Singleton factories, shared_ptr, and serialization, oh my!
by Bill Lear 20 Feb '05

20 Feb '05

I have a long question on how to combine a Singleton factory, serialization, shared pointers and an object hierarchy half of which will be created by a factory, and half of which will not. I think solving this problem in an elegant way might be very useful for others, so if someone with more experience with these things could take the time to plough through this, we might get something that is very valuable to the rest of the community. I have a base class (Base) and several derived classes that fall into two categories: production classes that are created by a singleton factory, and test derived classes that are created "by hand" in test code: Base DerivedProductionA DerivedProductionB DerivedTestA DerivedTestB A Singleton factory is used to create "production" Base objects by examining a string key and available data on the file system. If certain conditions obtain, DerivedProductionA is created, otherwise DerivedProductionB is created, and the key used to create the object is used to set a property in the object so it "knows" its creation key. The created object is stored in a hash map by key and a reference (currently, a raw pointer, but I'm contemplating using shared_ptr) to the object is returned. The Base object is used by other objects that need to be serialized: class Thing { Base* my_base; template <class Archive> void save(Archive& ar, unsigned int) const { // TBD } template <class Archive> void load(Archive& ar, unsigned int) { // TBD } }; Currently, the save/load methods inspect the Base object's creation key. If the key is blank, the object is serialized directly (a test class). If the key is not blank, the creation key is serialized (thus, a "production" class). Before this is done, a boolean flag is serialized indicating that a creation key was used to store the object or the object itself was stored. This is it, in rough form: template <class Archive> void save(Archive& ar, unsigned int) const { bool flag = key.size() != 0; ar << flag; if (flag) { ar << my_base->key(); } else { ar << my_base; } } template <class Archive> void load(Archive& ar, unsigned int) { bool flag; ar >> flag; if (flag) { string key; ar >> key; my_base = Factory::create(key); } else { ar >> my_base; } } Now, this works just fine, but it is a bit inelegant (a friend calls this uninheritance). I would prefer to be able to encapsulate the logic of serialization in a separate class, something like this: class BaseHandle { Base* my_base; template <class Archive> void save(Archive& ar, unsigned int) const { // As above. } template <class Archive> void load(Archive& ar, unsigned int) { // As above. } }; Then, the Thing class, and any other class that would want to serialize a Base object would be straightforward: class Thing { Base* my_base; template <class Archive> void save(Archive& ar, unsigned int) const { ar << my_base; } template <class Archive> void load(Archive& ar, unsigned int) { ar >> my_base; } }; My question is: Has anyone else run across this type of pattern? I would prefer to use a shared pointer to the Base class throughout and to hide the constructors of all Base (and its derived classes), to force allocation of these objects through special static alloc methods that create shared_ptr-wrapped objects. My problem is I don't quite know how to combine all of these ideas. For example, using shared_ptr, class Thing would be quite simple: typedef shared_ptr<Base> BasePtr; class Thing { BasePtr my_base; template <class Archive> void save(Archive& ar, unsigned int) const { ar << my_base; } template <class Archive> void load(Archive& ar, unsigned int) { ar >> my_base; } }; However, now I've broken the previous work: I'd have to go back and put all of the serialization logic for factory construction back in the Thing class itself. If I try to combine all of this in the BaseHandle class, I run into difficulties: typedef shared_ptr<Base> BasePtr; class BaseHandle { BasePtr my_base; template <class Archive> void save(Archive& ar, unsigned int) const { bool flag = key.size() != 0; ar << flag; // Ok, now what? Do I just proceed as before and // pick up the pieces in the load method?? if (flag) { ar << my_base->key(); } else { ar << my_base; } } template <class Archive> void load(Archive& ar, unsigned int) { bool flag; ar >> flag; // Ok, now I know how my BasePtr was created: either // through the factory, or through the static alloc() method. // But, is the following appropriate? if (flag) { string key; ar >> key; my_base = Factory::create(key); } else { ar >> my_base; } } }; I tried sketching this out with BaseHandle inheriting from shared_ptr (don't even know if that's possible or at all advisable), which seemed to me to be the most elegant solution: typedef shared_ptr<Base> BasePtr; class BaseHandle : BasePtr { template <class Archive> void save(Archive& ar, unsigned int) const { bool flag = key.size() != 0; ar << flag; // Is this reasonable? Base* my_base = get(); if (flag) { ar << my_base->get(); } else { ar << my_base; } } template <class Archive> void load(Archive& ar, unsigned int) { bool flag; ar >> flag; // Oy, now what?? Base* my_base; if (flag) { string key; ar >> key; my_base = Factory::create(key); } else { ar >> my_base; } // OK, I've got Base* now, fully built. // how do I make "this" (shared_ptr) wrap // this?? // Do I do this? : *this = BasePtr(my_base); // or this??: reset(my_base); } }; If someone could help out here, I'd really appreciate it. Thanks. Bill

proposed modif for boost connection
by frantz.maerten＠igeoss.com 19 Feb '05

19 Feb '05

I took a look at libsidc++ and found very interresting the way of blocking/unblocking connections. I added some small modifications in boost::signals lib in order to have this functionality (2 patches in attachment to apply at the parent of the boost_1_32_0 distrib). Only the interface of connection has changed (3 new methods), and I added a boolean flag in basic_connection struct. So, my questions are: 1) is it interresting to incorporate it (for me, YES, it is veru useful)? 2) is it a safe implementation? You can test it like that: MySignal sig ; boost::signals::connection conn1 = sig.connect(&fct1) ; boost::signals::connection conn2 = sig.connect(&fct2) ; sig(10) ; // call fct1 and fct2 conn1.block() ; sig(20) ; // call only fct2 conn1.unblock() ; sig(30) ; // call fct1 and fct2

boost::fsm and templated states
by Jan Eickmann 19 Feb '05

19 Feb '05

Hi, I'm trying to get templated states to work with boost::fsm. Background is that I want to create an OptionsDialog I can show from different screens. So for now this works: template<class ParentState> class OptionsDialog : public boost::fsm::simple_state< OptionsDialog<ParentState>, ParentState, boost::mpl::list< boost::fsm::transition<EvOptionsExit, ParentState>, boost::fsm::custom_reaction<EvOptionsSound>, boost::fsm::custom_reaction<EvOptionsSoundExit> > > { //... }; This works perfectly so far. Now, what I want to do is have inside of the OptionsDialog substates (one for the sound-panel, one for video, etc.). This is my attempt so far: template <class Parent> class InnerInitial; template<class ParentState> class OptionsDialog : public boost::fsm::simple_state< OptionsDialog<ParentState>, ParentState, boost::mpl::list< boost::fsm::transition<EvOptionsExit, ParentState>, boost::fsm::custom_reaction<EvOptionsSound>, boost::fsm::custom_reaction<EvOptionsSoundExit> > >, InnerInitial< OptionsDialog<ParentState> { //... }; template <class Parent> class InnerInitial : public fsm::simple_state<InnerInitial<Parent>, Parent> { }; When trying to compile this (and of course using the OptionsDialog as a substate somewhere) I get the following compiler errors (sorry, I know it's long, but I couldn't make any sense of it so I don't know whats important). Could anyone shed some light on this?

lexical_cast and wstring on VC 2003
by steve ahlgren 18 Feb '05

18 Feb '05

Hello : I would like to use lexical_cast to convert to/from std::wstring on vc 2003 but I'm failing. These fail : int foo = boost::lexical_cast< int >( std::wstring( L"1" ) ); std::string bar = boost::lexical_cast< std::string >( std::wstring( L"a" ) ); std::wstring fred = boost::lexical_cast< std::wstring >( std::string( "Fred" ) ); Any hints would be greatly appreciated and kindly rewarded with good programming karma. Thanks in advance; Steve a.

I'm looking for applications using Boost and STL with source code available
by Matthew Johnson 18 Feb '05

18 Feb '05

I would like to study a gui application designed from the ground up with modern C++ techniques and built on top of STL and Boost. Ideally I am looking for an application that abstracts the system specific ui components (windows, controls, etc) as much as possible. The ideal application would: Implement significant, non-trivial functionality. Be elegant and efficient. Use modern C++ and implementation design techniques. Be built on top of STL and Boost. Use the best techniques for the job (metaprogramming, generic programming, functional programming, oo, etc) Have source code available for study (not necessarily available for legal use). Last but not least, a native Mac OS X application would be ideal. Does anyone here know of any applications that meet these requirements? I have been studying modern C++ for a while now and would like to study real world applications and uses of the these techniques and libraries as a next step in this study. Thanks, Matthew

unit test and BOOST_CHECK_CLOSE
by Thomas Lemaire 17 Feb '05

17 Feb '05

dear list, When executing a test defined by: BOOST_CHECK_CLOSE(t3.x(3), 0.0, epsilon); I get the message: difference between t3.x(3){2.34188e-17} and 0.0{0} exceeds 1e-08% where obviously the difference does not exceeds the given threshold 1e-08... What's going on ? -- thomas

metaprogramming exercise 2-0
by Chris Goller 17 Feb '05

17 Feb '05

I just finished the first exercise in the C++ meta programming book. Then I checked what had been done before on this mailing list. Here is my solution: using namespace boost; template <bool use_ref, typename T> struct add_const_ref_impl { typedef T const & type; }; template <typename T> struct add_const_ref_impl<true, T> { typedef T type; }; template<class T> struct add_const_ref { typedef typename add_const_ref_impl<is_reference<T>::value, T>::type type; }; From Bruce Trask comes: using namespace boost; template<typename T> struct add_const_ref { typedef typename add_reference<typename add_const<T>::type>::type type; }; His solution is SO much better then mine. However, when I first saw it I thought it must be wrong because I assumed that add_const on a reference would would return a const reference. In other words, the code below would be false: bool a = is_same<add_const<int &>::type, int &>::value; However! bool "a" is true. So my question is why is "a" true? Why isn't add_const<int &>::type == int const &? Thanks, Chris

See http://www.boost.org/libs/test/doc/components/test_tools/floating_point_com… for more detailed description of algorithm used in BOOST_CHECK_CLOSE. Either I do not understand something or you cannot use BOOST_CHECK_CLOSE for direct comparison with 0.0. Inequations given never satisfied in case one of arguments is zero. I think you could write BOOST_CHECK(t3.x(3) >= -epsilon && t3.x(3) <= epsilon); given that epsilon is non-negative. -- Best regards, Vladimir mailto:vkrasovsky@yandex.ru

Interval Arithmetic Tribool
by Robert Ferguson 16 Feb '05

16 Feb '05

Dear list, I hope I am writing to the correct place, and that this isn't a frequently asked question.. but I'd like to know alittle about comparisons and the Interval library. I am using intervals in a search algorithm to take advantage of the natural inclusion function as proposed in a paper I'm trying to implement. So far so good, except that I'm a little unhappy that I have to use "try" and "catch" to detect the indeterminate case. I'd like to use the boost::logic::tribool to identify the semi-frequent indeterminant case. For example: tribool cmp = interval1 < interval2; if (!indeterminate(cmp)) { if (cmp) { // something } else { // something else } else { // something } When I do this and the indeterminate case happens, an exception triggers and the function quits. This could be an error on my behalf, but it seems like this the default behavior. Its not that I can't do the try, catch, its just a matter of style. Can I have my cake and eat it too? Best, Robert Ferguson

Program runs OK in Cygwin, but got "Segment Fault" in Linux
by Welson Sun 16 Feb '05

16 Feb '05

Hi, The program is really simple, it creates a graph and output to a .dot file using the graphviz library in the BGL. It runs well in Cygwin, but in Linux, it got a segment fault when outputing the vertex id. Can you C++ gurus see what is going on? Thanks! Welson

[Boost.Test] and assert()
by Richard Jennings 16 Feb '05

16 Feb '05

When testing my program using the Unit Test Framework I find that if the program fails an assert() it is aborted with the message "Abnormal program termination" and no more tests are run. Is this the expected behaviour? The release notes for Boost.Test v1.30.0 say that a handler was added for SIGABRT (raised by abort() called by assert()) so I was expecting the test framework to catch this exception and report it in a similar way to a divide-by-zero error. I have my code compiled in debug with Borland C++ Builder 6.0 running on Windows XP. The behaviour is the same whether the command line option --catch_system_errors=yes or no. Richard

starting to learn Boost MPL and type_trait
by Sharon Galtzur 16 Feb '05

16 Feb '05

Hello all, I am trying to start learning the Boost MPL. The internals are more interesting for me then the usage I read both Abrahams&Gurtovoy and Alexandrescu books (both excelent btw) Some things i still don't quite understand: 1. How (or rather Why) does is_class works. 2. Same for is_enum 3. Can someone explain how MPL lambda works specially how the "_" works I tried to scan some of the archives but could not find any definite answer - i guess the discussions if they were are lost. P.S. neat trick to someone who try to learn the internals is to make a program that just include the header u interested to learn and just do the "pre-compile" stage (/EP /P flags in VC7.1 iirc) - you get a nice header without the unreadable MACROS. Thanks

Inserting elements in extensible associative sequences
by Lemings, Eric B. (Contr) 15 Feb '05

15 Feb '05

The semantics of MPL's insert metafunction for an extensible associative sequence is defined as: "For any Extensible Associative Sequence s, iterator pos in s, and arbitrary type x: typedef insert<s,x>::type r; Semantics: r is concept-identical and equivalent to s, except that at< r, key_type<s,x>::type >::type is identical to value_type<s,x>::type." What happens if the key type of x is already in s? Thanks, Eric.

OT: std::map<>::operator[] and default constructor
by Noel Yap 15 Feb '05

15 Feb '05

Please direct me to a more appropriate list if this is too off topic: It's come to my attention that our vendor's std::map<>::operator[] /always/ calls the default constructor of the key even when the key already exists in the map. This is what they say: It turned out to be a documentation bug. Our implementation is in sync with the standard. From 23.3.1.2 [lib.map.access]: T& operator[](const key_type& x); -1- Returns: (*((insert(make_pair(x, T()))).first)).second. Notice the T() in the call to make_pair() above: that's an invocation of the default ctor of the mapped type (i.e., Aoeu in the user's test case). So the program behaves as expected. If you do not like this behavior, replacing the expression map[16] in the program with map.find (16)->second will avoid the construction of the unused temporary. I modified the test case to incorporate this change. My inclination is to say the standard is a spec, not an implementation. Allowing std::map<>::operator[] not to call the default constructor requires no more and promises no less than the spec. All this is true unless, of course, there's some order of complexity issue I'm missing. But someone else had said, "an implementation has to have the same 'observable behaviour' as the abstract machine defined in the standard. Calling the default ctor definitely counts as observable behaviour, so I don't think RW have any choice but to implement it this way". What's the best place to get an official answer to the real intent of std::map<>::operator[]? Must it /always/ call the default constructor? Thanks, Noel

date_time: time_duration operator bug?
by Donato Petrino 15 Feb '05

15 Feb '05

Hello, I noticed that the "operator/()" isn't declared "const", I think this is an error. If so, can I correct it in my copy of boost (1_32) and hope that in the next version this is fixed? Further, I miss the "operator/(const time_duration&)", is there a reason why there isn't such a thing? BTW, I just read an old thread (Sep. 2003) about double arithmetic for the time_duration operators '*' and '/'. What's the plan here, is it going to stay 'int'-based (because I wrote my own double-based ones, not really nice I have to say). tia Donato

serialization newbie question
by Dave Gomboc 15 Feb '05

15 Feb '05

I've downloaded boost 1.32, downloaded bjam, ran the vcvars32.bat for MSVC7.1, ran bjam install, updated Tools | Options | Projects | VC++ Directories | Libraries to include "C:\Boost\lib" first.

Possible error in serialization library

I ran some of my code through valgrind and it detected the use of an uninitialized value in the serialization library, as reported below: ==21969== Use of uninitialised value of size 8 ==21969== at 0x80A9CE3: void boost::archive::xml_oarchive_impl<boost::archive::xml_oarchive>::save<double>(double const&) (xml_oarchive.hpp:53) ==21969== by 0x80A9CD6: void boost::archive::save_access::save_primitive<boost::archive::xml_oarchive, double>(boost::archive::xml_oarchive&, double const&) (oserializer.hpp:97) ==21969== by 0x80A9CB1: boost::archive::detail::save_non_pointer_type<boost::archive::xml_oarchive, double>::save_primitive::invokex(boost::archive::xml_oarchive&, double const&) (oserializer.hpp:217) ==21969== by 0x80A9C97: boost::archive::detail::save_non_pointer_type<boost::archive::xml_oarchive, double>::invoke(boost::archive::xml_oarchive&, double const&) (oserializer.hpp:309) I took a peek at the code, but I can't see anything obviously wrong, so the report may be spurious.

generating an unique Identifier - integer- in the Method Scope - at compil time
by Olivier Vanden Bos 14 Feb '05

14 Feb '05

Not really a Boost relative question, but actually my current idea is making a STRING-CRC at compil time, and i imagine that perhaps in Boost Crc Library or Metaprogramming there is some useful things. i wanna do something like Object::Method() { int ID= CRC(__FILE__,__LINE) } actually i used only __LINE__, but i 've got trouble when the object is overloaded and the overloaded methods occurs at the exact same line in a different CPP, as i use the ID to retrieve some local information (method scope) in the current object through a map. If anyone as some idea or can redirect me on some information, Boost relative or not , it will be helpful. thanks in advance. - VDB - "LNK2019: unresolved external symbol" Olivier Vanden Bos MSN#TheVdeub(a)hotmail.com AI Programmer UBISOFT Montreal

Regex link issues
by Aaron Nauman 14 Feb '05

14 Feb '05

I have upgraded by stlport libs to 4.6.2 (from 4.5) and boost libs to 1_32_0 (from 1_26_0). I am getting odd linking errors in the regex library. I am on vc6 sp5 and linking dynamically. If I have something like this in the code, it links fine boost::regex test("foo"); But if I use an std::string, I get link errors. For example, this code std::string testStr("bar"); boost::regex test(testStr); Produces link errors vc.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: unsigned int __fastcall boost::reg_expression<char,class boost::regex_traits<char>,class boost::detail::allocator_adapter<char,class boost::detail::simple_alloc> >::se t_expression(class _STL::basic_string<char,class _STL::char_traits<char>,class _STL::allocator<char> > const &,unsigned int)" (__imp_?set_expression@?$reg_expression@DV?$regex_traits@D@boost@@V?$all ocator_adapter@DVsimple_alloc@detail@boost@@@detail @2@@boost@@QAIIABV?$basic_string@DV?$char_traits@D@_STL@@V?$allocator@D@ 2@@_STL@@I@Z) I dumped the exports for the library and there is mismatch in _STL and std namespaces.

"template with C linkage"
by Chris Coleman 14 Feb '05

14 Feb '05

Hi, I'm struggling with Boost (1.32) on Solaris 8 at the moment - I do not have root access to the machine. The default compiler is gcc-2.95, and so has no <ostream> <locale> etc so the -sTOOLS=gcc toolset won't work. I then thought that the solution would be to install STLPort, but can't get this to build cleanly. Since then I have discovered that there is another version of gcc (gcc-3.2) hidden in /opt/sfw/gcc-3.2. With this I then built the boost libraries again, and installed them with the line: bjam "--prefix=/staff/cqc/ -sGCC_ROOT_DIRECTORY=/opt/sfw/gcc-3.2 -sTOOLS=gcc" install This seemed to work fine with no problems at all. I then moved the headers, and the libs to the approprite places, and set about compiling my project. The result below is repeated many many times about various files: /opt/sfw/gcc-3.2/bin/gcc -DHAVE_CONFIG_H -I. -I. -I.. -D_REENTRANT -c -o zz_broker.o `test -f zz_broker.cpp || echo './'`zz_broker.cpp In file included from /opt/sfw/gcc-3.2/include/c++/3.2/utility:66, from /staff/cqc/include/boost/config/select_stdlib_config.hpp:20, from /staff/cqc/include/boost/config.hpp:40, from /staff/cqc/include/boost/smart_ptr.hpp:14, from zz_broker.h:28, from zz_broker.cpp:24: /opt/sfw/gcc-3.2/include/c++/3.2/bits/stl_relops.h:91: template with C linkage /opt/sfw/gcc-3.2/include/c++/3.2/bits/stl_relops.h:104: template with C linkage /opt/sfw/gcc-3.2/include/c++/3.2/bits/stl_relops.h:117: template with C linkage /opt/sfw/gcc-3.2/include/c++/3.2/bits/stl_relops.h:130: template with C linkage I have searched the list archives and googled around quite alot, but can't seem to find any info.

Re: [Boost-users] Re: Concatenation of many std::string
by Chateauneu Remi 14 Feb '05

14 Feb '05

Can I suggest this implementation which, thanks to your ideas, brings some speed-up, sometimes important ? It has to be used exactly like 'concat()' or 'fastcat()' that were suggested here. It has some specialised templates for char and fixed-size char arrays, which occur often in string concatenations, and have the advantage that their size is known at compile-time. -- DSL Komplett von GMX +++ Superg�nstig und stressfrei einsteigen!

compiling a project
by Noah Schwartz 13 Feb '05

13 Feb '05

Hi, Im running Gentoo over here and I installed boost from gentoo's portage tree. I then tried to compile a program that included boost/python.hpp. It completely failed: /usr/include/boost/python/detail/wrap_python.hpp:41:24: patchlevel.h: No such file or directory /usr/include/boost/python/detail/wrap_python.hpp:121:21: Python.h: No such file or directory Looks like I don't have some local variables set to tell things im trying to build where to find these files. Im compiling this absurdly simple program (pretty much just an #include <boost/python.hpp> and a main that returns 0) using a Makefile. Do I need to export some paths? If so, which vars? Do I need to add something to my g++ line? I've never used python's interpreter in c++ and so im not sure what I need to add to my Makefile. Sorry if im not being clear...its kind of late. thanks, Noah

RE: [Boost-users] [Signals] Named slot group usage?
by Brian Braatz 11 Feb '05

11 Feb '05

I do not use named slots. I do however wish that I could Add META-DATA to the slot. Specifically, for debugging I would like signals to store a user supplied structure with the slot. Why I am requesting this: I have one library that rides on top of signals\slots extensively. Because I am using it quite extensively, it is difficult to debug. I want to be able to "go back later" and have code that can tell me where that slot "came from". Right now, I keep this separate in a vector<mystruct>. This is ugly, because the slot can disappear without the vector knowing about it. The other thing I would also like to use this functionality for would be this: Fire a signal, where only slots that get notified are the ones that match an expression which checks the metadata I have provided. Even if I have to do this manually- this would be a nice feature for my usage of slots\signals.

Reverse of boost::bind?
by Jonathan Biggar 11 Feb '05

11 Feb '05

I can use boost::bind to use a function that takes several arguments in a context where it is passed fewer arguments: void f1(int, double); boost::function<void(double)> f2(boost::bind(f, 1, _1)); f2(1.0); Is there something a way to do the reverse, which is to call a function that takes fewer arguments in a context where it is passed more arguments? void f3(int); boost::function<void(int,double)> f4(/*what goes in here?*/); f4(1, 1.0); Or am I stuck writing the function mapping by hand? -- Jon Biggar Levanta jon(a)levanta.com

[Signals] Named slot group usage?
by Douglas Gregor 11 Feb '05

11 Feb '05

I'm trying to determine how widely used named slot groups are in the Signals library. I would appreciate it if I could get some feedback on if they're used, how they're used, etc. In particular: (1) Do you use named slot groups? (2) Did the FIFO ordering guarantees in 1.32.0 and the ability to add to the front or back of the slot list alleviate the need for named slot groups? (3) If performance of connection/disconnection of named slot groups were to get worse (e.g., linear in the number of slots), would it seriously impact the performance of your application? Responses should probably come to me, personally, unless they would be of interest to the group. Background: Signals performance is sub-par, and much of the problem can be traced back to support for named slot groups. I'm trying to determine the best way to proceed. Thanks, Doug

Problem with autotools + options
by Uzytkownik 11 Feb '05

11 Feb '05

1. How check does and where boost is by Autotools(autoconf+automake)? I try to check by AC_CHECK_HEADERS(boost/filesystem/path.hpp,,exit), but it don't work. 2. How in program_options use the options from list? For example --method=[http,ftp] Thanks. -- Linux user: #376500 (patrz http://counter.li.org/)

problem with push_relabel_max_flow
by Matthias Linkenheil 11 Feb '05

11 Feb '05

Hi, I used the edmunds_karp_max_flow algorithm in my project and it worked fine. Then I changed it to the push_relabel_max_flow algorithm but it doesn't work. I get an access violation at line 562 in the push_relabel_max_flow.hpp . Line 560: ai = out_edges(u, g).first; -> u is the node, that is directly connected with the source, when access violation occurs. Have anyone a suggestion where the problem could be? Thanks, Matthias

Concatenation of many std::string
by Chateauneu Remi 11 Feb '05

11 Feb '05

I'm working on an application with many std::string concatenations, everywhere. This is consuming a lot of CPU resources, due to temporary strings, memory allocation, etc... Due to the size of the existing code, it is not possible to make big changes. I tried first to transform these kind of expressions: std::string a = b + c + d + e ; ... into ... std::string a(b); a += c ; a += d ; a += e ; ... and it is definitively faster, but not enough. I've then worked on a method, just by adding a special object after the '=' sign, which transforms these concatenations into a two pass operation, the first to calculate the total length and allocate the destination string, and the second pass to actually copy the source strings into the destination. One just need to re-write the concatenations this way : std::string a = my_special_object() + b + c + d + e ; But maybe I am reinventing the wheel. Is there in Boost, a way to speed up this kind of operation ? Thanks in advance. -- DSL Komplett von GMX +++ Superg�nstig und stressfrei einsteigen!

building boost::regex lib with mingw from gnu/linux
by atoral＠dlsi.ua.es 11 Feb '05

11 Feb '05

Hi, I would like to use the boost regex lib in a c++ program. This is being developed under gnu/linux (Debian-Sarge Kernel 2.4.27) with gcc 3.3.5. Also, we are creating binaries for Win32 by cross compiling with MinGW (i586-mingw32msvc-g++ (GCC) 3.4.2 (mingw-special)). Thus, i have to build the boost::regex library for both gnu/linux and win32. There was no problem to get the linux version (it is included in Debian, and anyway the source succeded to compile), but i'm having trouble to compile the win version. I compile from <boost_root_dir>/boost_1_31_0/libs/regex/build by using generic.mak (make -f generic.mak). in this file i've just added these lines: CXX=i586-mingw32msvc-g++ LINKER=i586-mingw32msvc-ar This is the output i obtain: xxxxx@xxxxx:~/boost/boost_1_31_0/libs/regex/build$ make -f generic.mak i586-mingw32msvc-g++ -o generic/boost_regex/c_regex_traits.o -c -O2 -I../../../ ../src/c_regex_traits.cpp ../src/c_regex_traits.cpp: In static member function `static size_t boost::c_regex_traits<boost::regex_wchar_type>::strnarrow(char*, size_t, const boost::regex_wchar_type*)': ../src/c_regex_traits.cpp:1052: error: `wcstombs' is not a member of `std' make: *** [generic/boost_regex/c_regex_traits.o] Error 1 any clues about what i'm doing wrong? thanks

Well Daniel, You were right, i was mixing up both the namespaces and that screwed up the code. Now i'm qualifiying the bind function, with the appropriate namespace. That solved the problem. Thanks, Surya

BOOST_STRONG_TYPEDEF
by gast128 08 Feb '05

08 Feb '05

Dear all, I was playing with the serialization library, and ran into the BOOST_STRONG_TYPEDEF. In our own development environment we have a similar feature based on the article 'True typedefs' from Matthew Wilson (CUJ march 2003): BOOST_STRONG_TYPEDEF(long, HBLA); BOOST_STRONG_TYPEDEF(long, HBLUB); HBLABLA hBla(1); HBLUB hBlub(3); bool bOk = false; bOk = (hBlub == hBla); //rejected if base types are different bOk = (hBlub != hBla); //does not compile on VC 7.1 bOk = (hBlub < hBla); //rejected if base types are different hBlub = hBla; //accepted by boost_strong_typedef, this is a deliberate choice So I guess one can discuss about some behavior. But perhaps if it supports '==', it should also support '!='? Wkr, me

boost::signals block/unblock
by frantz.maerten＠igeoss.com 08 Feb '05

08 Feb '05

Hi all, Maybe a stupid question: I wonder there's a way to connect a slot to signal (which gives a connection), temporarily disconnect this connection, and reconnect it later (like a block function) My problem is that I need to emit a signal to the connected slots given a condition. If a connection satisfies the precondition, it will be notified, otherwise it is temporarily disconnected. Thanks for any help

msvc vc 6.0 SP6 internal heap limit reached
by Ira 08 Feb '05

08 Feb '05

All, I am a newbie who is trying out the serialization library. In that article, there is a demo program (demo.cpp) that i am trying to build. Along with several warnings ('dynamic_cast' used on polymorphic type...), the compiler is generating the following error: fatal error C1076: compiler limit : internal heap limit reached; use /Zm to specify a higher limit I have tried various values for /Zm (200 is recomended) and either i still receive this error, or if increase the value too much, the compiler generates the following error: fatal error C1204: compiler limit : internal structure overflow Since this seesaw response doesn't seem correct, i am wondering if there is a particular flag or combination thereof that would correct this problem? Thank you.

Boost libraries and no exceptions
by David Ward 08 Feb '05

08 Feb '05

Boosters: In our embedded environment, we compile everything with -fno-exceptions. I'm getting errors in the new program_options library because it has naked throw calls in it. I did see a definition of boost::throw_exception and changed the naked throw calls to use that. That seems to work. However, naked throw calls are littered throughout many of the libraries. Is there some generic way to get these libraries to compile with -fno-exceptions or do I have to go through and change all calls to throw to boost::throw_exception? Thanks, David Ward Acterna

Bind question
by Surya Kiran Gullapalli 07 Feb '05

07 Feb '05

Hi all, This is a follow up to my previous message on boost::bind question. Please go thru the attached program. I've 2 structures X an Y, and i'm calling stable_sort on vectors of both the objects. But in one stable sort, i'm using the member variable directly, and in the other i'm using a member function to access that. When i use boost::bind with member variable directly, it has no problem (structure Y), But if i use member function to access the member variable, which is private, i'm getting compilation errors, The essence of the compilation error is given below.. ===================== ./boost/include/boost/lambda/detail/actions.hpp:86: error: no matching function for call to `boost::lambda::function_adaptor<int (X::*)()>::apply(int (X::*const&)(), const X&)' ./boost/include/boost/lambda/detail/function_adaptors.hpp:193: note: candidates are: static Result boost::lambda::function_adaptor<Result (Object::*)()>::apply(Result (Object::*)(), Object*) [with RET = int, Object = X, Result = int] ./boost/include/boost/lambda/detail/function_adaptors.hpp:197: note: static Result boost::lambda::function_adaptor<Result (Object::*)()>::apply(Result (Object::*)(), Object&) [with RET = int, Object = X, Result = int] ===================== what am i doing wrong. thanks in advance, Surya

Bind question
by Surya Kiran Gullapalli 07 Feb '05

07 Feb '05

Hi all, I'm having this particular class class File { public: int get_size(); std::string get_name(); private: int size, std::string name; } ; and a vector of objects of this class. vector <File> files ; and if want to sort the elements of the container i use stable_sort (files.begin(), files.end()) // Invokes operator < if its defined. otherwise shows up an error. there's another form of stable_sort, in which we can call a sorting function of our own. Now my problem is the sorting criteria i use is dependent on runtime. say at times i want to sort by size and at other times i want to sort them by name of the file. The simple solution could be write 2 functions, sort_on_size and sort_on_filename which does the work. Now, the sorting order is also decided at runtime. So i write 2 more functions for that. The problem is the number of functions i use increase like any thing, which does not look good. The best way should be to use bind (or am i wrong here ?) from Boost library. But i'm not getting the syntax correctly here. the crude way could be stable_sort (files.begin(), files.end(), (bind (&File::get_size, _1) > bind (&File::get_size, _2))) ; that is call get_size() on first argument, and call get_size() on second argument, and compare those values, and return a boolean value. Can anybody please help me out with the syntax here. ?? Thanks in advance, Surya

Signals and fuction documentation really old?

..or am I having a day of profound stupidity. documentation: Boost.Function 3.5 Comparing Boost.Function objects me: okay, boost function object wrapper objects are comparable. documentation: Chapter 5 FAQ 5.1 Comparison between boost::function objects cannot be implemented well, and therefore will not be implemented. me:okay so it is not implemented documentation: 5.1 This essentially negates the usefulness of operator==in the context in which it is most desired:multitarget callbacks. me: great, multitarget callbacks is exactly why I am reading all this documentation documentation: 5.1 The Signals library has a way around this. me: great, if I only had an example of that way that wouldn't contain 2 free functions declared in the same file as the signal itself. Any help in clearing up my confusion greatly appreciated Tony

deepcpy_ptr
by gast128 06 Feb '05

06 Feb '05

Dear all, I couldn't find functionality a la deep copy pointer in boost. Isn't this an idea to extend the smart_ptr library with it? Basically it has the same functionality as if the object was hold by value, but sometimes you want to dismiss the header file and only have a fwd decl: #include "bla.hpp" struct Foo { Bla m_Bla; }; deep copy: class Bla; //fwd decl. is sufficient { deepcpy_ptr<Bla> m_ptr; }; Or do I overlook something?

I'm running on gentoo linux and I believe this started happening when I recently upgraded from gcc 3.3.4 to 3.3.5. Originally I was using boost 1.31.0 but I have tried upgrading to 1.32.0 and also upgrading gcc to 3.4.3. I have not yet tried downgrading gcc to 3.3.4 but that's pretty much next on the list. I really don't know for sure what is causing this, but it really is quite annoying. It could be gentoo's packaging of gcc or something else, or it could be gcc or boost, or ... I do see a few similar sounding posts such as http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg74258.html but so far haven't been able to fix the problem. Any help or insight would be greatly appreciated. Cheers, Derek

Linker Problem with Regex Libraries VC7
by Nicholas Cardi 06 Feb '05

06 Feb '05

The linker is complaining that it can't find the file libboost_regex-vc71-mt-sgd-1_32.lib This file was not built when I made the regex library. Here is the exsact linker error: fatal error LNK1104: cannot open file 'libboost_regex-vc71-mt-sgd-1_32.lib' The file libboost_regex-vc7-mt-sgd-1_32.lib does exist on my machine and it is in my include directory. >From the install document Finally when you use regex++ it is only necessary for you to add the <boost> root directory to your list of include directories for that project. It is not necessary for you to manually add a .lib file to the project; the headers will automatically select the correct .lib file for your build mode and tell the linker to include it. Is it possible the headers are referancing the wrong lib file? Thanks Nicholas Cardi

[variant] is_a/can_be
by Yuval Ronen 05 Feb '05

05 Feb '05

Hi. I encountered the need to query a boost::variant to which type it currently contain. I'm talking about something like: variant<int, string> v(3); assert(v.is_a<int>()); assert(!v.is_a<string>()); This can be done using the which() method, but its drawback is that I rely on the order of the types in the variant declaration rather on the type, which is really what I'm interested in. I can implement the variant_is_a<>() feature using a visitor such as: template <typename T> struct is_a_visitor : public boost::static_visitor<bool> { template <typename U> bool operator()(const U &) const { return false; } bool operator()(const T &) const { return true; } }; template <typename T, class Variant> bool variant_is_a(const Variant &v) { return v.apply_visitor(is_a_visitor<T>()); } but this way has a problem: calling variant_is_a<double>() on a variant of type variant<int, string> (no double for this variant) will simply return false, rather than just not compile, which is what I prefer. Making this not compile will require a new feature from variant: a boolean constant 'can_be'. With this, the variant_is_a() function could be written with additional line: BOOST_STATIC_ASSERT(Variant::can_be<T>::value); IMO, the is_a/can_be features are general and useful enough to be included in the library. Wouldn't you agree? Yuval

implementing an iterator
by Chris Goller 04 Feb '05

04 Feb '05

I'm using iterator_facade to implement an iterator over file based data. So, my question is, since deference returns a reference to a value does that reference need to persist when the iterator is incremented or decremented? Because this is file based data I can't always keep a reference around because the data is stored on disk. Thanks, Chris

Use of dollar signs in variable names when using boost::archive::xml_iarchive
by lloyd.reed＠leica-microsystems.com 04 Feb '05

04 Feb '05

I have found a bug or undocumented limitation in the boost serialization library. I'm using VC++ 2003, which allows you to use variable names which include dollar signs ($). Variables with names containing dollar signs can be saved to an archive using the boost::archive::xml_oarchive class. When boost::archive::xml_iarchive is used to reload the variable, however, the parsing of the variable name fails, and basic_xml_iarchive<Archive>::load_start(const char *name) calls boost::throw_exception( archive_exception(archive_exception::stream_error) ). For example, std::string filename( "C:\\dollar.txt" ); int $(0); { std::ofstream archive_file( filename.c_str() ); if( archive_file.good() ) { boost::archive::xml_oarchive output_archive(archive_file); output_archive << BOOST_SERIALIZATION_NVP( $ ); } } produces the following file: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="3"> <$>0</$> </boost_serialization> but trying to load the file causes a boost::archive::archive_exception to be thrown: { std::ifstream archive_file( filename.c_str() ); if( archive_file.good() ) { boost::archive::xml_iarchive input_archive(archive_file); input_archive >> BOOST_SERIALIZATION_NVP( $ ); // throws } } I think the spirit definitions for the names of variables are in C:\boost_1_32_0\libs\serialization\src\basic_xml_grammar.ipp and C:\boost_1_32_0\libs\serialization\src\xml_grammar.cpp. Name = (Letter | '_' | ':') >> *(NameChar); and template<> void xml_grammar::init_chset(){ Char = chset_t("\x9\xA\xD\x20-\xFF"); Letter = chset_t("\x41-\x5A\x61-\x7A\xC0-\xD6\xD8-\xF6\xF8-\xFF"); Digit = chset_t("0-9"); Extender = chset_t('\xB7'); Sch = chset_t("\x20\x9\xD\xA"); NameChar = Letter | Digit | chset_p("._:-") | Extender ; } ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.

shared_ptr on HP-UX - patch
by Jaroslav Gresula 04 Feb '05

04 Feb '05

I tried to compile the smart pointer regression tests on HP-UX and found out that the compiler takes the 'advanced' version of get_deleter() template function (defined in shared_ptr.hpp) which is evidently beyond its limits (we use aCC, version HP ANSI C++ B3910B A.03.35). In case anyone is interested, I attached a 'patch' against shared_ptr.hpp, revision 1.52 - it just redirects the compiler to the already existing workaround version. /Jarda *** shared_ptr.hpp.orig Wed Feb 2 22:12:50 2005 --- shared_ptr.hpp Wed Feb 2 21:49:23 2005 *************** *** 442,448 **** // get_deleter (experimental) ! #if (defined(__GNUC__) && (__GNUC__ < 3)) || (defined(__EDG_VERSION__) && (__EDG_VERSION__ <= 238)) // g++ 2.9x doesn't allow static_cast<X const *>(void *) // apparently EDG 2.38 also doesn't accept it --- 442,450 ---- // get_deleter (experimental) ! #if (defined(__GNUC__) && (__GNUC__ < 3)) ||\ !

weak_ptr_test - non-portable?
by Jaroslav Gresula 04 Feb '05

04 Feb '05

When I run the weak_ptr_test (a part of the regression tests) on HP-UX (aCC version HP ANSI C++ B3910B A.03.35) I'm getting a lot of failures. The reason is that IMHO the weak_ptr_test.cpp relies on a non-portable construct. There is copy_assignment() template function which takes shared_ptr<> by value. All caller sites of this function pass on an unnamed shared_ptr<> temporary. The first line of copy_assignment() checks if shared_ptr<>::unique() is true for the passed object. This test succeeds for all compilers we use in our shop but for the aCC. The reason is that upon entering copy_assignment() shared_ptr::use_count() is equal 2 as the compiler creates a temporary on the caller site and copy-ctor is used to pass on the object to copy_assignment() which seems to be in concert with the C++ standard [12.2]. Is my observation correct? Thanks, Jarda

[mpl::transform] How to make metafunction from transform?
by Vyacheslav E. Andrejev 04 Feb '05

04 Feb '05

Hello All! I want to parametrize mpl::transform to form a new metafunction. But I have confused with mpl syntax and notations. Imagine, I have following vector typedef boost::mpl::vector<Type1, Type2, Type3, Type4> types; and following transformation: typedef boost::mpl::transform< types , boost::is_convertible<Type3, boost::mpl::_1> >::type result; The result of the tansformation is a bool vector that indicates whether Type3 is convertible to any of type from types vector. Now I want to form metafunction that will construct such array not from Type3, but from its argument. Of course, I may use straightforward method: struct WhoConverted { template <typename ConversionType> struct apply { typedef typename boost::mpl::transform< types , boost::is_convertible<ConversionType, boost::mpl::_1> >::type type; }; }; But it seems more like workaround rather than solution. Can it be done in more convenient and short manner by means of all mpl machinery like mpl::lambda, mpl::bind, placeholders, etc... ? -- Vyacheslav E. Andrejev System Architect, Excelsior, LLC

Build problems with Sun Studio 8 compiler
by steven.sims＠invensys.com 04 Feb '05

04 Feb '05

Hi, I'm very new to boost & jam - wanting to use boost::format for internationalisation. I'm having problems building on Solaris 9 using the Studio 8 compiler and accompanying stlport4. Best results so far are using BBv2 (with boost 1.32.0 distribution I get 100 targets built, 8 failed, 5 skipped). I've read a lot of the online doco but now grinding to a halt. This is what I have: Platform: SunOS 5.9 Generic_112233-12 sun4u sparc SUNW,Sun-Fire-V240 Compiler: Sun C++ 5.5 Patch 113817-08 2004/04/13 Distribution: boost-jam-3.1.10 & boost_1_32_0 The tarballs are unpacked in ./boost-jam & ./boost respectively. I added following lines to my user-config.jam: using sun ; using stlport : : /opt/Studio8/SUNWspro/prod/include/CC/stlport4 ; >From my top-level Makefile, bjam builds ok, then I kick off the boost build: ( \ PATH=`pwd`/boost-jam/bin.solaris:${PATH} ; \ BOOST_BUILD_PATH=`pwd`/boost/tools/build/v2 ; \ export PATH BOOST_BUILD_PATH ; \ cd boost ; \ bjam --v2 \ ) The build errors in the 8 failed targets are mostly template-related (no surprise there!). By minor tweaks to a few sources, I'm down to 3 failed, 2 skipped; but the remaining problems I find a bit more obscure. I can post actual errors if desired, but my initial questions are: # Am I doing anything obviously dumb in the above? Eg. should I be using BBv1 rather than BBv2? # Is anyone successfully building with this compiler? If so, what magic am I missing? Plus any other advice would be appreciated (however switching compilers is not an option :) Steve Sims

Hi everyone, I'm getting some link errors when I try to use the serialization library. I'm using VC7.1 and other modules (array, tokenizer, assign) seem to compile and link fine. Also, is there built-in support for serialization of boost::array? If not, it's easy to create one, of course. thanks, Kevin The errors I'm getting are: boost_tests error LNK2019: unresolved external symbol "public: __thiscall boost::archive::basic_binary_oprimitive<class boost::archive::binary_oarchive,class std::basic_ostream<char,struct std::char_traits<char> > >::~basic_binary_oprimitive<class boost::archive::binary_oarchive,class std::basic_ostream<char,struct std::char_traits<char> > >(void)" (??1?$basic_binary_oprimitive@Vbinary_oarchive@archive@boost@@V?$basic_ostream@DU?$char_traits@D@std@@@std@@@archive@boost@@QAE@XZ) referenced in function "public: virtual __thiscall boost::archive::binary_oarchive_impl<class boost::archive::binary_oarchive>::~binary_oarchive_impl<class boost::archive::binary_oarchive>(void)" (??1?$binary_oarchive_impl@Vbinary_oarchive@archive@boost@@@archive@boost@@UAE@XZ) boost_tests error LNK2019: unresolved external symbol "protected: virtual __thiscall boost::archive::detail::basic_oarchive::~basic_oarchive(void)" (??1basic_oarchive@detail@archive@boost@@MAE@XZ) referenced in function "public: virtual __thiscall boost::archive::detail::common_oarchive<class boost::archive::binary_oarchive>::~common_oarchive<class boost::archive::binary_oarchive>(void)" (??1?$common_oarchive@Vbinary_oarchive@archive@boost@@@detail@archive@boost@@UAE@XZ) boost_tests error LNK2019: unresolved external symbol "public: __thiscall boost::archive::basic_binary_iprimitive<class boost::archive::binary_iarchive,class std::basic_istream<char,struct std::char_traits<char> > >::~basic_binary_iprimitive<class boost::archive::binary_iarchive,class std::basic_istream<char,struct std::char_traits<char> > >(void)" (??1?$basic_binary_iprimitive@Vbinary_iarchive@archive@boost@@V?$basic_istream@DU?$char_traits@D@std@@@std@@@archive@boost@@QAE@XZ) referenced in function "public: virtual __thiscall boost::archive::binary_iarchive_impl<class boost::archive::binary_iarchive>::~binary_iarchive_impl<class boost::archive::binary_iarchive>(void)" (??1?$binary_iarchive_impl@Vbinary_iarchive@archive@boost@@@archive@boost@@UAE@XZ)

accessing the underlying C array of a boost::array
by Frank Hess 02 Feb '05

02 Feb '05

Does anyone know what the preferred method of accessing the underlying C array of a boost::array is? In boost 1.32 there is a data() member which returns a const pointer, and a c_array() member which returns a pointer. Also, the elems member itself is public. But at http://www.josuttis.com/cppcode/array.html, the author states that data() can be used for both const and non-const pointers, and indeed it is so in the version he posts on his website http://www.josuttis.com/cppcode/array.hpp.html (which doesn't provide the c_array() member but overloads data() instead). -- Frank

regex_token_iterator bug?
by samantha Quark 02 Feb '05

02 Feb '05

Dear all, I just played a little bit with the regex_token_iterator ( boost v 1.32) and modified the "html" example. I found this (strange?) behavior when i "tokenize" a string. while (i != j) { std::cout << i++->str().length() << std::endl; } crashes at runtime at the last sub-match of a match with: mtest: ../boost_1_32_0/boost/shared_ptr.hpp:253: T* boost::shared_ptr<T>::operator->() const [with T = boost::regex_token_iterator_implementation<__gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, char, boost::regex_traits<char>, std::allocator<char> >]: Assertion `px != 0' failed. zsh: 24497 abort mtest test.html Whereas: while (i != j) { std::cout << i->str().length() << std::endl; i++; } works fine. Is this behavior a bug, or is it correct, that the first version does not work, if yes, why? Cheers, Joe. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[BGL] implementing operator < for edge_descriptors
by Max Schoebinger 02 Feb '05

02 Feb '05

Hello, I am trying to create a std::map<edge_descriptor, unsigned int>. Unfortunaltely, there is no less operator defined for edge descriptors, so i'd like to implement my own version based on a custom internal property associated with the edge. Is it possible to access an arbitrary property, solely based on an edge_descriptor without having access to the graph object? Here some pseudo-code: struct compare_edge_descriptors { bool operator()(edge_descriptor e1, edge_descriptor e2) { unsigned int val1 = get_property_somehow(e1.get_property(), my_custom_property); unsigned int val2 = get_property_somehow(e2.get_property(), my_custom_property); return (val1 < val2 ); } }; Do you have an idea how to implement "get_property_somehow"? Thanks, Max

boost-users: cant i use mpl::contains to find members of list_c ??
by suresh.t＠philips.com 02 Feb '05

02 Feb '05

hi, I was trying to use mpl::contains with list_c and it always seems to return mpl::false_. For example typedef mpl::list_c< int ,16,8 > mylist; typedef mpl::contains<mylist, mpl::int_<16> >::type tt; "tt::value" is zero though i thought 16 being in the mylist it would be 1. Can someone please let me know whether the usage is improper and if so what should be used to find elements in list_c? Thanks in Advance S.T

Exercices 3-3 and 3-4 (C++ Templates Metaprogramming)
by Philippe Mori 02 Feb '05

02 Feb '05

I'm not sure of the meaning of "twice twice" and "twice on itself" respectively. My guess would be for exercice 3 that I should do something like : typedef twice<to_be_filled_1>::type T1; // T1 would be T ** // The second time, I replace T (in to_be_fiiled_1) by // T1 (in to_be_filled_2) , thus T2 is T1** which is also T**** typedef twice<to_be_filled_2>::type T2; while for exercice 4, we want something that would look like : typdef twice<twice<to_be_filled_3a>to_be_filled_3b>::type T3; Does I understand the questions correctly? For twice, I use the definition from section 3.3.2. Philippe

Exercice 3-7 (C++ Templates Metaprogramming)
by Philippe Mori 02 Feb '05

02 Feb '05

I do not understand well the semantic of some constructs. 1) For t1, does the external mpl::lambda has any effect on some use of t1 or mpl::lambda<_1>::type and also mpl::lambda<_1> are always equivalent? 2) Does the uses of lambda in t8 has any effect or the result is always the same as with t2. 3) Does there are other tests that the ones below (i to vii) that would shows some other differences in the semantics of the expression? 4) Same question but for to_be_filled part of my tests. Anything different that the four ones belows (a to d)? 5) In any ot the tests with a to_be_filled part, is it possible to have more than one template argument and that the extra ones are used? The thing I have some of the following (what I have tried and what compile depends on the construct - that is t1, t2,...) : i) display_type(tn); ii) display_type(tn::type); iii) display_value(tn::type::value); iv) display_type(mpl::apply<tn, to_be_filled>::type) v) display_value(mpl::apply<tn, to_be_filled>::type::value) vi) display_type(tn::apply<to_be_filled>::type) vii) display_value(tn::apply<to_be_filled>::type::value) where tn is one of the type t1, t2,... t8 and to_be_filled is something similar to one of those : a) int b) X where X is a metafunction class c) mpl::plus<int_<1>, int_<2> > d) Y where Y is a simple metafunction similar to always_int in section 3.5.4. I have look at the documentation but it is hard to see the relation between each construct, the possible uses of each ones and their prmary purpose. I would be nice to provide more samples and more equivalences. Philippe

uBLAS sparse_matrix "default" value
by Austin Bingham 02 Feb '05

02 Feb '05

Apparently the wheels of the ublas mailing list move slowly, so I'm asking this question here. Is there any way to set the "default" value of a sparse_matrix? sparse_matrix seems to guarantee that you always get a value when you access an index, even if that index hasn't been explicitly set. For sparse_matrix<float>, for instance, you get 0. Is there any way to specify this value? That is, if I wanted to get back, say, -1 for unset entries, is there a way to do this? There's no direct mention of this that I can find, although there were some discussions of zero-constructors or somesuch that may have been dealing with this question. Thanks. Austin Bingham

mpl -> integral sequence wrappers -> wrapping enums ?
by Martin Pasdzierny 02 Feb '05

02 Feb '05

Hello MPL experts, I'd like to use meta - vectors of integral constants defined as enums. But unfortunately the code below does not compile. <code> #include <iostream> #include <boost/mpl/vector_c.hpp> #include <boost/mpl/size.hpp> enum MY_ENUM {X,Y}; // (*) typedef boost::mpl::vector_c<MY_ENUM,X,Y> my_vector_c; static const int size = boost::mpl::size<my_vector_c>::value; int main(int argc, char** argv) { std::cout << "\nsize:" << size << "\n... bye" << std::endl; } </code> After replacing line (*) with typedef boost::mpl::vector_c<int,X,Y> my_vector_c; the code compiles and runs fine, but this does not look type safe any more. Any suggestions ?! regards, Martin.

Re: Rationale for intrusive_ptr?
by Brian Neal 02 Feb '05

02 Feb '05

Well to answer my own question, I think, it can be used when you already have something that is reference counted and you want to manage it yourself. Also in places where new and delete aren't the correct actions. Or when you need something with less resource requirements than shared_ptr. For example, when multi-threading is turned on, shared_ptr asks for a mutex. Intrusive_ptr leaves that up to you. Am I getting close here? I didn't think about using it when you have a function that takes a shared_ptr but you need to pass in this. I dunno, I tend to use shared_ptr sparingly. If I don't need a shared_ptr, I don't ask for one on the interface to a function. That way the user can pass in a naked pointer or a shared_ptr::get(). I make sure to document what the function does (and does not do) with the input pointer though. Thanks. __________________________________ Do you Yahoo!? Yahoo!

equality fails with C++ bools
by Ross Boylan 02 Feb '05

I have a function declared bool that is acting rather non-bool. std::cout << obj.fn() gives me "76" and BOOST_CHECK_EQUAL(obj.fn), true) fails, with the message /home/ross/peter/R/mspath/src/test/Covariates_test.cc(178): error in "obs_covariates": test env.matchesObservation() == true failed [76 != 1] std::cout << true prints "1". obj.fn() works OK as an argument to if (obj.fn()). I am using g++ 1:3.3.5-5 on Debian GNU/Linux. I've tried -O2 and -O1; same behavior either way. boost is 1.31.0-9 The function is declared bool matchesObservation() const Maybe bool is being typedef'd or #define'd to int somewhere, for compatibility with old code? Probably not; I tried printing typeid(xxx).name() and got "b" for true and the function return value, while I got "i" for the number 1. I tried tracing into the code with limited success. Some mix of the fact that the underlying libraries weren't a debug version, that the code was optimized, and that there are #line directives (the source files were generated out of another file) made it hard to follow.

Hi, I have defined the following: bigint* bigint_constructor(long_ l){ return new bigint(to_bigint(l)); } class_<bigint>("bigint") .def("__init__", make_constructor(bigint_constructor)) .... .... implicitly_convertible<boost::python::long_, bigint>(); Now I want to have a implicit conversion from long_ to bigint. My original c++ class has no constructor with long_ but my python-bigint class. The compiler tries to find one on c++ bigint and doesn't find it. How should I use implicitly_convertible to reach my goal? Benjamin

Two issues with lexical_cast
by Yuval Ronen 01 Feb '05

01 Feb '05

Hi. I'm probably just another one out of a million who make these remarks, but I found nothing in the documentation about them, so I'll mention them anyway. 1. lexical_cast(Source arg) takes the source argument by value. Why not by const& ? Calling lexical_cast(some_basic_string) now makes a copy of the source argument for no reason. 2. lexical_cast ignores trailing whitespaces, but not leading whitespaces. Meaning that int a = lexical_cast<int>("3 "); // three-space will work and return 3, but int a = lexical_cast<int>(" 3"); // space-three will throw. Why? There's no rationale here. Both cases should be treated in the same manner, and IMHO, that manner should be throwing. After a look at the code, it seems that the trailing-whitespace-ignore code ('stream >> std::ws' in line 151) was specifically added, so there was supposed to be a reason for this. But as I said, I believe this is wrong, at least as the default behaviour when converting a string to something else. Maybe some policies (IgnoreLeadingWhitespace, IgnoreTrailingWhitespace) can be added to control this? And again, I suppose I'm not the first to think of it... Thanks, Yuval

[Nat] Consider: class MyClass; void some_func(const boost::shared_ptr<MyClass>& ptr); class MyClass { public: void process() { // BAD THINGS HAPPEN! some_func(boost::shared_ptr<MyClass>(this)); } }; In our current project, we've been bitten more than once :-( by situations that are analogous but less obvious. Inside a member function, you don't have a shared_ptr<MyClass>, you only have a dumb MyClass* 'this' pointer. But if MyClass is managed with smart pointers, you probably have processing functions that accept only a smart pointer to MyClass. A natural-looking data conversion is easy to code and makes the compiler happy. What happens, though, is that when you instantiate a new shared_ptr<MyClass> from your dumb 'this' pointer, it gets a whole new refcount object! In the example above, the temporary shared_ptr<> goes away as you're about to exit MyClass::process() -- which makes its spurious refcount go to 0 -- which deletes the MyClass instance in question, even though there are probably still existing shared_ptr<MyClass> references to the same instance lying around! (e.g. the one with which you called the process() method) We now use intrusive_ptr almost exclusively (vs. shared_ptr). We limit its intrusiveness by deriving all subject classes from an intrusive_base we wrote, which contains the refcount we use and a couple of methods. This practice has cut down considerably on bizarre crashes.

implicitly_convertible<a,b>
by Benjamin Schmeling 31 Jan '05

31 Jan '05

Hi, I have exposed a bigint class which has no constructor for long_ . I added an additional constructor by defining .def("__init__", make_constructor(bigint_constructor)) This works fine. Now I want to use the implicitly_convertible function which expects from the class to have an constructor which takes the first argumen (in this case a long_) I used implicitly_convertible<boost::python::long_ ,bigint> but now the problem is that the original c++ class has no such constructor, but the wrapped class. How can I make him use my new constructor in implicitly_convertible? Benjamin

Compile problems with multi_index on CW 9.3 (mac)?

I'm trying to use boost::multi_index for the first time, and I'm getting odd compile errors. I have a class with two "keys", a text one and a numeric one, and I want to have two indices into the collection. So, I tried several things, and all of them get the same error: 'index_class' is not a member of class 'boost::multi_index::ordered_unique<boost::multi_index::identity<Foo>, boost::multi_index::detail::null_arg, boost::multi_index::detail::null_arg>' (and then an amazing cascade after that) Here's the basic idea: typedef boost::multi_index_container < Foo, boost::multi_index::indexed_by < boost::multi_index::ordered_unique < boost::multi_index::identity < Foo >, LessThanNumeric >, boost::multi_index::ordered_unique < boost::multi_index::identity < Foo >, LessThanText > > > Foo_; where LessThanNumeric (and LessThanText, too) looks like this: struct LessThanNumeric: std::binary_function< Foo, Foo, bool > { bool operator () ( const Foo& x, const Foo& y ) const { return x.NumericKey () < y.NumericKey (); } }; My source is at <http://www.idio.com/misc/mi-test.cpp> Anyone got any tips?

Hi, I am currently writing a gtkmm component which acts as a file browser, much like a small filemanager which can be embedded in gtkmm applications as a scrolled window. I have just rewritten the component to use the boost::filesystem classes instead of the C functions for interacting with the filesystem. However I am getting a strange error when I start my app: When iterating through a directory I suddenly get the message: Aborted. void FileBrowser::rebuild_file_list() { namespace boostfs = boost::filesystem; boostfs::path cur_path( m_cur_dir ); FileContainer tail; // m_files will first only contain directories, // while tail will contain only files m_files.clear(); try { boostfs::directory_iterator end; for( boostfs::directory_iterator dir( cur_path ); dir != end; ++dir ) { std::cout << (*dir).string() << std::endl; if( boostfs::is_directory( *dir ) ) m_files.push_back( *dir ); else tail.push_back( *dir ); } } catch( std::runtime_error & e ) { std::cerr << e.what() << std::endl; } m_files.sort( SortedByName() ); tail.sort( SortedByName() ); drx::list_concat( m_files, tail ); } OUTPUT: [...] /home/mkay/.acrobat /home/mkay/.synce /home/mkay/.gimp-2.0 /home/mkay/.fonts /home/mkay/.designerrctb2 /home/mkay/.eclipse /home/mkay/.gftp /home/mkay/.ntrc_2 /home/mkay/.DCOPserver_anthrax__0 /home/mkay/.DCOPserver_anthrax_:0 /home/mkay/.kpackage /home/mkay/.fonts.conf /home/mkay/.xscreensaver /home/mkay/xdefaults_old /home/mkay/.reslisarc /home/mkay/.aMule /home/mkay/.gtkrc Aborted At this point the application exits. Any idea what is causing this? Thanks in advance, Matthias

enabling boost::threads for HP-UX
by Oliver Kowalke 31 Jan '05

31 Jan '05

Hi, I want to use boost on HP-UX together with gcc-3.3.2. As I figured out that thread-support is disabled (BOOST_DISABLE_THREADS is defined in file boost/config/platform/hpux.hpp). Up gcc-3.3 posix-threads are supported on HP-UX-plattform (http://gcc.gnu.org/install/specific.html#hppa*-hp-hpux11) Is it then save to remove #define BOOST_DISABLE_THREADS in boost/config/platform/hpux.hpp? with best regards, Oliver -- "Der Spezialist ist ein Barbar, dessen Unwissenheit nicht allumfassend ist."

Setting the path to use Boost
by Grek 31 Jan '05

31 Jan '05

Hi fellow Boost users! I am new to the Boost Graph Library (BGL) and I have a query about setting the path to access the library. My platform is Cygwin. I want to use the g++ command and incorporate the BGL in it. How do I go about it? Let's say that I want to use the dijkstra's algorithm. I set the path as follows: boost_1_32_0/libs/graph/example Then I typed the following. g++ -g dijkstra-example.cpp But it displays error messages and I do not know how to proceed. It would be of great help if anyone could tell me how one has to set the path to use the dijkstra's algorithm in a program. Thanks for taking the time to read through this!

atlanta statics...

http://houseandhome.msn.com/pickaplace/comparecities.aspx?FromState=WA&From… Hope this link works for you. It takes 5 min. to load a page from website for me. Microsoft's MSN uses windows technology now I guess... The big thing that stands out for me is crime. Seattle is above the national average by about 2x, Atlanta appears to be between 7 and 8 times! I'll have to consider such a move with care....

Thread stack size
by Thorsten Froehlich 30 Jan '05

30 Jan '05

Hi, Googling I found a thread "Boost.Threads. Anything happening?" (in July 2004) in comp.lang.c++.moderated that suggests there should be a development branch of the thread code that already supports this feature. Unfortunately I cannot find the right branch for it in the boost CVS (using the web CVS viewer). The thread_dev and thread_development branches I found do not appear to be the correct ones as they have not been changed for a very long time and the above mentioned thread suggests it would be a rather recently added feature. While I could add this feature myself for the platforms that I need, I would prefer to avoid duplicating work already done. Could someone point me where to find the branch referred to in the above mentioned comp.lang.c++.moderated thread? Regards, Thorsten Froehlich

Bug in lexical_cast<> with doubles
by Leon Raj 29 Jan '05

29 Jan '05

I think I've found a bug in the boost::lexical_cast<> library (v1.31.0) on WinXP SP1, MSVC 6.0 (sp5) and MSVC.NET 2003. --- Start code snippet --- #include <boost/lexical_cast.hpp> #include <iostream> int main( int argc, char* argv[] ) { double dMax = = std::numeric_limits< double >::max(); // On a Win32 x86 system, dMax is now 1.7976931348623157e+308 // This is successful and strMax is "1.797693134862316e+308" std::string strMax = boost::lexical_cast< std::string >( dMax ); try { double newDMax = boost::lexical_cast< double >( strMax ); std::cout << "Successfuly" << std::endl; } catch ( boost::bad_lexical_cast& ) { std::cout << "Failed to cast" << std::endl; } // On a Win32 x86 system, this always fails, // because (I think) strMax overflows a double, // because 1.7976931348623157e+308 is *rounded UP* // to 1.797693134862316e+308, which cannot be // represented by a double } --- End code snippet --- ----------------------------------------------------- Leon Raj Senior Engineer Invetech Pty.

Unit test case inheritance problem
by Bill Lear 29 Jan '05

29 Jan '05

I am having trouble working around a problem with inheriting unit test cases. Suppose I have a base class Foo and several derived classes. Suppose I have a corresponding base test case and I would like to reuse that base test case with test cases for the derived classes. What I would like to do is this, in highly stylized form: class BaseFooTestCase { public: virtual Foo* create() = 0; void test_base() { Foo* foo = create(); // test foo ... } void add(test_suite* ts) { ts->add(BOOST_CLASS_TEST_CASE(&BaseFooTestCase::test_base, this); } }; class DerivedFooTestCase { public: virtual Foo* create() { return new Derived(); } void test_derived() { Foo* foo = create(); // test foo } void add(test_suite* ts) { BaseFooTestCase::add(ts); ts->add(BOOST_CLASS_TEST_CASE(&DerivedFooTestCase::test_derived, this); } }; Then, something like this: test_suite* init_unit_test_suite(int, char* []) { auto_ptr<test_suite> ts(new test_suite("test")); DerivedFooTestCase* tc = new DeriveFooTestCase(); tc->add(ts); return ts; } However, I can't get the add() methods in the test case classes worked out. The BOOST_CLASS_TEST_CASE macro seems to want a shared_ptr, and passing "this" to it does not seem to work. Could anyone please provide an example of how to do this? Every time I try to work this out, I end up with a mess --- static allocator methods, weak_ptr wrapped by shared_ptr, and other workarounds --- all of which works, but is really quite a lot of effort for what I want and is overly complex for me to recommend to my team as a solution. Any help appreciated. Thanks. Bill
