So it's perfectly reasonable to not free it. I could've sworn we just went through this a few months back. Perhaps its time to put a comment that links to the appropriate boost mailing thread. http://lists.boost.org/boost-users/2005/08/13538.php Might be related?

[GRAPH] How to use an external edge weight map in dijkstra_shortest_paths
by rohit wadhwa 24 Jan '06

24 Jan '06

Hi, I am a newbie and have been struggling over the past couple of days with dijkstra_shortest_paths. I want to use WeightMap as an external property. I create the Graph as follows typedef boost::adjacency_list<boost::vecS,boost::vecS, boost::directedS,boost::no_property, boost::property<boost::edge_index_t, std::size_t> > Graph; I added edges using add_edge(fromVertex, toVertex, edge_index, Graph); My edge_index can have any long value and they are not necessarily in sequence. Also, I want to create the weight map on the fly and want to use a std::map. I have tried all sorts of things but to no avail. Any help will be appreciated. Thanks, Rohit.

[iostreams] non-copyable device with Boost.Ref pattern
by Pedro Lamarão 24 Jan '06

24 Jan '06

Here follows a simple pattern to use Boost.IOstreams with your non-copyable Device, allowing you quick access to formatted input and output: #include <boost/iostreams/stream.hpp> #include <boost/ref.hpp> #include "foo_device.hpp" /* Don't; just to make lines shorter. */ using boost::iostreams; using boost; class foo_device; class foo_stream_base { public: /* Define constructor forwarding to foo_device. */ foo_stream_base (...) : _M_device(...) {} protected: foo_device _M_device; }; class foo_stream : private foo_stream_base, public stream<reference_wrapper<foo_device> > { public: /* Define constructor forwarding to foo_device. */ foo_stream (...) : foo_stream_base(...), stream<reference_wrapper<foo_device> >(ref(_M_device)) {} }; -- Pedro Lamarão Desenvolvimento Intersix Technologies S.A.

boost::iostreams - access object 'below' the stream
by Leon Mergen 24 Jan '06

24 Jan '06

Hello, Little question: I'm toying around to replace my socket_stream class with a boost::iostreams::stream class to implement a more generic approach... now, I use the socket file descriptor/handle as a unique identifier in my application, and so far this could easily be retrieved; however, when the boost::iostreams::stream "layer" is on top of my socket class, this is pretty much inaccessable. What is the most common approach to handle this problem ? I really don't want to resort to some kind of tuple which describes the stream and the handle, but at the moment, a construction like that is the only thing my mind can come up with... any suggestions ? Thanks in advance for any reactions. Regards, Leon Mergen

thread library
by Robert Hanson 24 Jan '06

24 Jan '06

I'm looking at porting a windows (win32) app to linux. Is there a good reason to consider the boost thread library over the linux thread library? Does boost provide a wrapper for threads, so that I won't need to change my source code when porting between the two?

How to reduce the boost library size

24 Jan '06

Hi I compiled version 1.33.1 under a Windows XP machine with MingW (gcc 3.4.2). The compiling is very smoothing. However the size of directory "boost" is around 1.27 GB. I believe there is some command to clean the building lib, but I could not find it. Any suggestion? thanks!

Tokenizer usage, combining escaped_list_ and char_?
by Jeremy Tudisco 24 Jan '06

24 Jan '06

I'm attempting to process a scripting language from a file through tokenizer (only recently found out about Spirit, more on that later), and am having difficulties, namely, in processing input like this: "[ ExampleRoutine input; switch( input.messageNumber ) { 1: "Number 1"; 2: "Stand. On one foot (and jump around)"; 3: ! a comment to be ignored input.messageNumber = 1; break; } ];" The ending quotes mark the input as a string literal, the internal are part of the file. The problem comes from the fact that I need to process certain separators as tokens, such as braces, parentheses, periods, end lines, etc, but also allow escape characters in the case of the quotes, which should be treated as one returned token. My current method of processing this is: typedef char_separator<char> CharSep; typedef tokenizer<CharSep> CharTokenizer; typedef CharTokenizer::iterator CTokenIter; const CharSep g_RoutineSep(" \t\n,", "\"';[]{}()<>.!"); #define S_QUOTE "\"" ... // meanwhile, inside a function body CharTokenizer tok( getRoutineFromFile(), g_RoutineSep ); CTokenIter curTok( tok.begin() ); for(; ( curTok != tok.end() ) && ( *curTok != S_CBRACKET ); ++curTok ) { string curWord; if( ( *curTok == S_QUOTE ) { for(++curTok; ( *curTok != S_QUOTE ) && ( curTok != tok.end() ); ++curTok) { curWord += *curTok + ' '; // sure, we could check to see if *curTok is a punctation mark, and if so // not include that last space, but a better way must exist! } } else { // assume it's a command word, and process it here } } Of course, this is prone to gross misinterpretation, as "switch( input.messageNumber )" would be handled in each iteration as "switch", "(", "input", ".", "messageNumber", ")". Yet, this same functionality breaks the string literal into unnatural spacings, as the above code would turn it into "Stand . On one foot ( and jump around ) ", which isn't desired. However, as it stands, escape_list_separator doesn't return the separators, it just acts upon them, so all that fancy operator parsing isn't possible out of the box, requiring breaking things like "switch(" and "input.messageNumber" into separate things. Possible, yes, but extra work. So, the question. Could my needs be satisfied by defining my own TokenizerFunction, and if so, is there a simpler/more exhaustive reference besides the page? Or, conversely, is it time to look into Spirit? - Veni, Vidi, Vemaili. I came, I saw, I replied. -- Jeremy Tudisco, circa now.

Re: [Boost-users] How to reduce the boost library size
by Merrill Cornish 24 Jan '06

24 Jan '06

Jianhong, If you did a simple Boost build without restricting the output, then your Boost output directory will have many variants of each library. For example, you will have static and dynamic libraries; libraries with and without debug information, libraries with and without threading. And, for each of the above, you will have a two copies of the library named with and without the Boost version number (e.g., -1_31_1) as a suffix. If you decided what combination of debug/threading/static/version you want, you can delete the others, or at least move them elsewhere. Merrill

boost thread does not honour BOOST_ALL_DYN_LINK
by Inge Norum 24 Jan '06

24 Jan '06

The boost thread library does not honour the BOOST_ALL_DYN_LINK setting in config/user.hpp. Thread used to be only available as a dynamically linked library in version 1.31, and I see a note about this in the comment for BOOST_ALL_DYN_LINK. I guess that it now ought to honour this general setting, to avoid defaulting to static linkage even when this is defined? Regards, Inge Norum thread/detail/config.hpp: #if defined(BOOST_THREAD_BUILD_DLL) //Build dll #elif defined(BOOST_THREAD_BUILD_LIB) //Build lib #elif defined(BOOST_THREAD_USE_DLL) //Use dll #elif defined(BOOST_THREAD_USE_LIB) //Use lib #else //Use default # if defined(BOOST_HAS_WINTHREADS) # if defined(BOOST_MSVC) || defined(BOOST_INTEL_WIN) //For compilers supporting auto-tss cleanup //with Boost.Threads lib, use Boost.Threads lib # define BOOST_THREAD_USE_LIB # else //For compilers not yet supporting auto-tss cleanup //with Boost.Threads lib, use Boost.Threads dll # define BOOST_THREAD_USE_DLL # endif # else # define BOOST_THREAD_USE_LIB # endif #endif

Re: [Boost-users] Multi-Index compound key synthesis via MPL
by Joaquín Mª López Muñoz 24 Jan '06

[Luke, this message from you shows up at Google Groups frontend, but somehow it hasn't really made it to the users list. Responding to the list in the hope that at least this answer gets properly processed.] Luke Meyers ha escrito: > The indexed_by construct for a multi_index_container can be replaced by > an mpl::vector, so that the list can be synthesized. I would like to > do the same thing with compound_key, to synthesize such a key based on > a list of types. Can I do this? Alas there's no version of composite_key accepting an MPL sequence instead of the direct enumeration of the constituent key extractors. But with a little MPL and preprocessor stuff, however, you can do what you want, see the attached snippet. HTH, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[Boost][Bind] How to bind template function member

beginners problems linking serialization library
by Michael Shapiro 24 Jan '06

24 Jan '06

I am having problems linking a program using the serialization library. I have made a small program, considerably simpler than the demo.cpp listed at http://www.boost.org/libs/serialization/doc/tutorial.html and I have also tried linking demo.cpp itself. My hpp files are in /home/mshapiro.local/boost/include/boost-1_32/boost/ My libraries are in /home/mshapiro.local/boost/lib/ I have tried linking this code with gcc 3.4.5 on a linux machine using gcc -I/home/mshapiro.local/boost/include/boost-1_32/ \ -L/home/mshapiro.local/boost/lib/ \ -lboost_serialization-gcc \ demo.cpp I have tried many variations on this! (For example, I have tried g++ instead of gcc, I have tried all variations on the serialization library, such as boost_serialization-gcc-d-1_32, etc, I have tried turning off warnings as suggested in the compiler specific issues.) I can compile using the -c flag, but I cannot link it. I get a large number of error messages all of which look much like /tmp/ccuSnkzu.o(.gnu.linkonce.t._ZN5boost7archive18text_oarchive_implINS0_13text_oarchiveEED1Ev+0x51): In function `boost::archive::text_oarchive_impl<boost::archive::text_oarchive>::~text_oarchive_impl()': : undefined reference to `boost::archive::basic_text_oprimitive<std::basic_ostream<char, std::char_traits<char> > >::~basic_text_oprimitive()' I can find various references to this exact problem in the newsgroups, but can find no solution to it. Your help would be greatly appreciated. Many thanks in advance, Michael Shapiro

Yep, I see. You're right. Well, you can refer to get<> as follows boost::tuples::get<N,typename Tuple::inherited> Note that this is not relying on undocumented implementation, so called "const lists" are explained and made public at http://boost.org/libs/tuple/doc/tuple_advanced_interface.html So I'd say you can use the former reference to get safely. > > However, I am wondering if there would be a problem to declare the > thin > wrapper simply like this (example with the const version): > > template< int N , > typename Tuple > > inline > typename tuples::access_traits< > typename tuples::element< N , Tuples >::type > >::const_type > get( const Tuple& t ) > { > return tuples::get< N >( c ) ; > } > > ? That would also work, but my proposal above is simpler.

trouble building bgl-viz
by VP of Communciations 23 Jan '06

I have successfully installed boost with VC express (windows), but am having trouble getting the DOT reader going. I don't seem to have the bgl-viz library. I have followed the directions on the "getting started" page and the read_graphviz page, but I must be doing something wrong, because I am not getting the bgl-viz library. I'm new to boost and C++, so please forgive me if these are elementary questions. How do I build the bgl-viz library? Thanks.

graph compile error with gcc3.3 when edge container is slist
by Weiqing Guo 23 Jan '06

23 Jan '06

Hi, the attached source code is copied from boost_1_33_0/libs/graph/example/adjacency_list.cpp, I only changed the edge container to be slist, and include <slist.h> I compiled it on linux with AMD opteron 844 processor. gcc2.95.3 works fine, but gcc3.3 doesn't compile.

Dear list, What would be a good way to tell if a file is saved by boost::serialization? I notice that the first several characters of binary_oarchive saved files are "\026 \0 \0 \0 \0 \0 \0 serialization" and are "22 serialization" for text_oarchive saved files. Are they reliable signatures? Many thanks in advance. Bo

Weird cross compiling issue
by James Hughes 23 Jan '06

23 Jan '06

Hello all, I am cross compiling Boost to an embedded Linux Arm architecture. I reported a problem a week or so ago with failures in some of the libraries which I was unable to solve, and have a bit more information. One of the issues appears with the serialisation library. Although I am compiling for Arm, the serialisation libs end up as Intel X86 binaries, even though all the other successfully compiled libs are ARM. This then leads to problems elsewhere with libraries that appear to need the serialisation libs. I can only think that there is an issue with the make system to do with serialisation area. Anyone have any comments/thoughts? In addition, when I do a build to a particular directory: bjam "-sGCC_ROOT_DIRECTORY=/opt/montavista/mobilinux/devkit/arm/iwmmxt_le" "-sGCC=iwmmxt_le-gcc" "-sGXX=iwmmxt_le-g++" stage the stage folder is created, in which is a lib folder, in which are all the binaries (including the defective Intel ones). However, I would also expect some header files somewhere - should there also be a h (or header) folder next to lib? If not where are the headers I need to include in my apps using Boost?

Version Mgmt classes/algorithms
by Rich Johnson 23 Jan '06

23 Jan '06

Today 09:06:47 am Hi folks-- I'm looking for a peer-reviewed solutions for managing versions (dll compatibiity, data formats, etc.). If they exist, they're pretty hard to find. ( FWIW, searches with the terms "version" or "versioning" aren't very helpful :-() To date all I've been able to find are ad hoc discussions on matching a specific version. Ultimately, I _think_ I'm looking for 1) a base class for a version specification 2) a range for version compatibility 3)a mixin class (with compatibility check methods) for objects requiring version compatibility. The two use cases I have in mind are: 1) - an application wishes to verify compatibility of a dlopen()'d module as well as the compatibility of its separately compiled objects. 2) - a decoder wishes to verify compatibility with a data file being decoded. Have there been any discussions on this topic in the boost domain? If so, how would I find it? Any one have ideas where else I could look? Or any useful codewords to search for. Thnx --rich

Hi! I try to build boost from source (boost-1.33.1 from sf.net) under debian stable on x86. In the first run I followed the "Getting Started" document but run into problems. In a second round I tried out the following additionaly: * I downloaded and extracted the sources (tar) to my BOOST_ROOT * I built bjam according the "Building Boost.Jam" instructions: http://www.boost.org/tools/build/jam_src/index.html#building_bjam --> bjam seems ok to me * In Step 4 before carrying out the install uncommented the ``using gcc ;`` line in BOOST_ROOT/tools/build/v2/user-config.jam * Step 5: In the BOOST_ROOT I tried to trigger install``bjam --v2 install`` Now I'm stuck here, googling around didn't help.

boost::serialization stream exception
by Adrian Grigore 23 Jan '06

23 Jan '06

Hi, I encountered a mysterious stream exception when trying to deserialize an std::map<std::string,long> container. The exception seems to occur depending on the data stored in the container. Unfortunately none of the hints regarding stream exceptions from the manual seem to help. The source code is as follows: >>>> std::map<RHANDLE,long> ArchiveEntries; ... void ResArchive::SaveToFile() { std::ofstream ofs (INDEX_FILE_NAME); boost::archive::binary_oarchive OArchive(ofs); OArchive <<ArchiveEntries; } void ResArchive::LoadFromFile() { std::ifstream ifs(INDEX_FILE_NAME); boost::archive::binary_iarchive IArchive(ifs); IArchive >>ArchiveEntries; //STREAM EXCEPTION!!! } <<<< I do not open any file stream to the index file in any other part of my source code, so multiple simultaneous streams can't be the problem. I can consistently reproduce the error for 2 given sets of test data, but I also have some test data ( just 2 entries instead of a few thousand) where the problem does not occur. I have not been able to isolate the exact data that is needed to cause such a stream exception though. Any hints on how to proceed would be greatly appreciated. Thanks in advance for your time! :-) Best Regards, -- Adrian Grigore -- Adrian Grigore adrian(a)lobstersoft.com Lobstersoft - Fun Brain-Bending Games For All Ages http://www.lobstersoft.com Member of the Association of Shareware Professionals

[iostreams] Error-handling with filters
by Paul Giaccone 23 Jan '06

23 Jan '06

How can you deal with a corrupt file when using filters? I have a chain of filters that includes a bzip2 and multichar filter have written myself. If the read() function fails to find what it expects in the file, it returns 0 (meaning "no characters read"). Otherwise it returns the number of characters read (which should be equal to the number of characters requested in the third function parameter) or -1 if the end of the file is reached. This works fine if the file is as is required, but if it is corrupted in any way, the program either hangs or crashes at if (s->strm != strm) return BZ_PARAM_ERROR; in bzlib.c, with s as a pointer that cannot be read (set to 0xcdcdcdcd). I'm working in Microsoft Visual C++ and gcc 3.2.3. How should this be handled? I haven't seen anything about it in the documentation. I imagine I should throw an exception instead of returning 0 (perhaps an iostreams exception?). Given that the crash is the bzip2 (bzip2 being the first operation done when deserialising the file), where would I put the associated catch block? Thanks, Paul

[Boost.Build v2] Incorrectly handled header dependencies
by Jaroslav Gresula 23 Jan '06

23 Jan '06

I'm using the CVS version of Boost.Build on WinXP. Consider the following project: top/ | +-- include/ | | | +-- dir/ | | | +--header.h +-- Jamroot +-- main.cxx // -- main.cxx #include <dir/header.h> int main() { return 0; } # -- Jamroot path-constant TOP : . ; exe app : main.cxx : <include>$(TOP)/include ; Modification of header.h does not invoke the app target. I'm not familiar with bjam at all, but there is one thing I noticed and which might be relevant. When bjam is run with -d7 the include directory appears in the bjam's output with leading '/' and 'header.h' itself is labeled as missing: set SEARCH = /c:/Temp/bb2/include set HDRSCAN = #[ t]*include[ ]*(<(.*)>|"(.*)") set SCANNER = object(c-scanner)@45 set HDRRULE = scanner.hdrrule set HDRGRIST = object(c-scanner)@45 build file: root = '/c:/Temp/bb2/include' dir = 'dir' base = 'header' search <object(c-scanner)@45>dir/header.h: /c:/Temp/bb2/include\dir/header.h build file: dir = '\c:\temp\bb2\include\dir' build file: dir = 'dir' base = 'header' search <object(c-scanner)@45>dir/header.h: dir/header.h build file: dir = 'dir' set SEARCH = set HDRSCAN = set SCANNER = set HDRRULE = set HDRGRIST = bind -- <object(c-scanner)@45>dir/header.h: dir/header.h time -- <object(c-scanner)@45>dir/header.h: missing made stable <object(c-scanner)@45>dir/header.h made* newer <p.-object(c-scanner)@45>main.cxx made+ update <pbin\msvc\debug>main.obj made+ update <pbin\msvc\debug>app.exe made update all -- Jarda

Hello: boost::filesystem with cygwin - windows style paths
by Simon Lam 22 Jan '06

22 Jan '06

Hello all, I've been fiddling around with the gnu gcc programming enviroment on cygwin, trying to make boost::filesystem work. I've hit a snag where the boost libraries consider my filesystem to be single rooted, and thus path won't take "c:\" as an argument. I've compiled the simple_ls.cpp program included in the documentation. It uses boost::filesystem::path::native_file_string(), and this returns a unix style path. I've tried running "simple_ls c:" but it complains that /home/<path to current dir>/c: is unavailable. I want to be able to use this in a program thats for windows, but independent of cygwin. Any ideas how to work around this? >Thanks >Simon (ps: yah! my first post!)

[Boost.Build v2] how to disable specific warnings on gcc
by Jaroslav Gresula 22 Jan '06

22 Jan '06

If I want to disable a specific warning on gcc (3.4.2, mingw) and use -Wall at the same time then on the gcc commnad line the -Wall option must precede the option disabling the specific warning. E.g. gcc -Wno-non-virtual-dtor -Wall main.cxx ignores the '-Wno-non-virtual-dtor' option, whereas gcc -Wall -Wno-non-virtual-dtor main.cxx works as expected. My problem is that I can't achieve the correct option order with Boost.Build v2 as the -Wall is used by default and the disabling option is always put before it. I tried to specify it in the toolset configuration: using gcc : : : <cxxflags>-Wno-non-virtual-dtor ; and also putting <toolset>gcc:<cxxflags>-Wno-non-virtual-dtor ; into project's requirements but neither works. Please, could anyone help me out with this? -- Jarda

[Win32 VC70 Linking] Hard coding library name for the final linking ('libboost_filesystem-vc7-mt-s-1_33_1.lib' ...)?
by Allen Zhao 22 Jan '06

22 Jan '06

Hi, All, I have a weired problem in linking libtorrent dll with my application. The libtorrent depends on 3 boost projects. This is what I got: test fatal error LNK1104: cannot open file 'libboost_filesystem-vc7-mt-s-1_33_1.lib' It looks like I have to build libboost_filesystem-vc7-mt-s-1_33_1.lib, and add this library explicitly in the final linking, no mater what my project setting is. The library filename must be named above. I also built a VC 7.0 from scratch (which contains all the needed boost source (not the prebuilt library)), it all ends the same linker error. Mystereous as it is, I am a little suspecious now. Is it possible that this library name is actually coded somewhere by some algorithm? Best regards, Allen Zhao

statechart: interaction with environment
by Oliver.Kowalke＠infineon.com 21 Jan '06

21 Jan '06

Hello, I try to understand how boost::statechart work - so I have some questions. If the FSM implements a communication protocol how does the FSM interact with the environment? 1. Problem: How to passing callback-functions to the FSM? * The callback should be invoked if the FSM is in a certain state and some conditions are met. * Do I have to pass the callback(s) with an event which has to be injected to the FSM from outside and store them in a given state? 2. Problem: How to pass initialization parameter into the FSM? * Some states need to be initialized with parameters (for instance host and port in order to create a socket). * Do I Have to pass the parameters via injected events? 3. Problem: How to pass data between several states in an FSM? * Same as Problem 2? With best regards, Oliver

gcc3.2 preprocessor concatenation or not on negative numbers

Hi all, Using gcc3.2 the concatenation of 1##Num where Num is negative leaves a space eg 1e#-1 --> 1e -1 as can be seen by the preprocessed output below. The only way round it that I can see is to simply not use a macro for this compiler Is there a preprocessor workaround for this problem? Is this even the correct behaviour? Any help appreciated. #define POW_EVAL(Num, Float_type)\ template <>\ struct pow_eval< \ Float_type BOOST_PP_COMMA() Num BOOST_PP_COMMA()\ 1 BOOST_PP_COMMA() false\ >{\ enum{ required = true};\ typedef Float_type result_type;\ result_type operator()()const\ { result_type result\ = static_cast< Float_type > (1e ## Num);\ return result;\ }\ }; POW_EVAL(-60, double) POW_EVAL(-59, double) POW_EVAL(58, double) POW_EVAL(57, double) // preprocessor output template <> struct pow_eval< double , -60 , 1 , false >{ enum{ required = true}; typedef double result_type; result_type operator()()const { result_type result = static_cast< double > (1e- 60); return result; } }; template <> struct pow_eval< double , -59 , 1 , false >{ enum{ required = true}; typedef double result_type; result_type operator()()const { result_type result = static_cast< double > (1e- 59); return result; } }; template <> struct pow_eval< double , 58 , 1 , false >{ enum{ required = true}; typedef double result_type; result_type operator()()const { result_type result = static_cast< double > (1e58); return result; } }; template <> struct pow_eval< double , 57 , 1 , false >{ enum{ required = true}; typedef double result_type; result_type operator()()const { result_type result = static_cast< double > (1e57); return result; } }; regards Andy Little

regex format string extension for more than nine captures
by Evan Burkitt 21 Jan '06

21 Jan '06

I need to be able to reformat match_results that contain more than nine captures using format strings. I'm looking for advice as to the easiest way to accomplish this. Is there some existing work I can build on or borrow from? I need syntax similar to the boost extended syntax, possibly using two digits for the capture number, e.g., '$01' It's important to me to be able to use the extended syntax's conditional expression '?Ntrue-expression:false-expression', again probably with two digits 'NN' in place of the single 'N'. Any help would be greatly appreciated. -eb-

[tuple] no easy access to get function
by Frank Birbacher 21 Jan '06

21 Jan '06

Hi! Today I wanted to std::transform a range of tuples into a sequence of one element. I thought I could just take the address of some tuple::get<N> function. Maybe also specify the Tuple type as template parameter. But from the source I figured the get function is not designed in a way that would allow me easy access. I had to write myself an additional function for this task (see below). Am I trying the wrong way? Or would you fix the implementation? template<size_t N, typename Tuple> typename boost::tuples::element<1,Tuple>::type const& getTupleElement(const Tuple& tuple) { return boost::get<N>(tuple); } to do: transform(..., ..., ..., &::getTupleElement<1,Tuple>); or //using boost::lambda for_each(..., ..., var(i) += bind(&::getTupleElement<1,Tuple>, _1)); I'd rather want to take the address of boost::tuple::get<N,Tuple>, but the template parameters won't match.

Parse errors when building against Insure++ by ParaSoft.
by Sven Delmas 20 Jan '06

20 Jan '06

I am trying to do some memory allocation debugging using Insure++ on my Windows machine. They use their own parser, and inject all kinds of fun stuff. However, their parser appears to be more restrictive (or just plain different) than the usual parsers. I end up with two parser errors: One in boost/details/indirect_traits.hpp (line 254 in boost 1.33.1): BOOST_STATIC_CONSTANT( bool, value = sizeof(detail::is_function_ref_tester(t,0)) == sizeof(::boost::type_traits::yes_type)); The error is: namespace "boost::detail" has no member is_function_ref_tester I can resolve that by taking the detail:: away, which seems to make sense if it indeed not part of the namespace. Can anyone confirm whether that is a valid solution/issue? The second issue is in boost/pool/detail/ct_gcd_lcm.hpp (line 68 in boost 1.33.1): BOOST_STATIC_CONSTANT(unsigned, value = ct_gcd2<B>::helper<A % B>::value); The error is: the global scope has no value I can resolve this by switching to the other branch with respect to the macro BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION. That compiles fine for VC 7.0, VC 7.1 and VC 8.0, so my question is whether it will produce the correct result, and if so, whether the visualc.hpp should be adjusted for those compiler. Any help would be appreciated. Thanks, Sven

Serialization "stream error" when using binary_iarchive/binary_oarchive & make_binary_object, but xml_iarchive & text_iarchive suceeds

In the mean time I would appreciate help from anyone that might have a suggestion. I've looked at the code and can find nothing wrong, as I said, ASCII and XML serialization works flawlessly I'm using Visual Studio 8 with Boost 1.33.1.

Re: [Boost-users] gcc3.2 preprocessor concatenation or not on negative numbers
by Merrill Cornish 20 Jan '06

20 Jan '06

Andy, I _think_ I may know why concatenation is working like it is. I believe the purpose of the ## concatentation operator is to cause one symbol (i.e., letters, numbers, underscore) to be created out of two symbols. Since the result of the concatenation that you specified is _not_ a legal symbol, the preprocessor appears to have made a best guess at what should be done rather than flag an error. Merrill

[Nat] These are things we changed in boost/boost/config/user.hpp: // BOOST_WHATEVER_DYN_LINK: Forces library "whatever" to be linked as a dll // rather than a static library on Microsoft Windows: replace the WHATEVER // part of the macro name with the name of the library that you want to // dynamically link to, for example use BOOST_DATE_TIME_DYN_LINK or // BOOST_REGEX_DYN_LINK etc (this macro is used to turn on __declspec(dllimport) // modifiers, so that the compiler knows which symbols to look for in a dll // rather than in a static library). // Note that there may be some libraries that can only be statically linked // (Boost.Test for example) and others which may only be dynamically linked // (Boost.Threads for example), in these cases this macro is unsupported. // #define BOOST_WHATEVER_DYN_LINK #define BOOST_FILESYSTEM_DYN_LINK #define BOOST_SIGNALS_DYN_LINK #define BOOST_PYTHON_DYN_LINK // BOOST_ALL_NO_LIB: Tells the config system not to automatically select // which libraries to link against. // Normally if a compiler supports #pragma lib, then the correct library // build variant will be automatically selected and linked against, // simply by the act of including one of that library's headers. // This macro turns that feature off. #define BOOST_ALL_NO_LIB

Thanks a lot for this. I have a quick question - I would like to build the static library and not the DLL. Could you tell me what should be changed in the project apart form the "General->static lib"? Do you know how to disable the auto-link of boost?

Hi, Thanks for help, I did not understand your statement properly -> did you create your own VC 7.1 projects for the three libraries? Is this a standard procedure what people do when something is not working in boost? Could you give me your compiler/linker options and setting so that I could make something similar?

Thanks for help, I would like to build (compile and link) some examples from the filesystem directory. Can anyone tell me how to do this? In which file I can find the compiler and linker flags used by bjam for vc-7_1-stlport build?

[Review][fixed_string] : First Example

Hi Reece, When I started of with the first example in the documentation I found that there some issues in compilation. All those issues are due to the two phase argument lookup problem that I have seen the second time today :-). Once I fixed it I was able to get a clean compile. Attached are the diff of modified files. 1. basic_string_impl.hpp.diff and 2. and fixed_string.hpp.diff The Compiler that I am using is $ g++ -v Reading specs from /usr/lib/gcc/i686-pc-cygwin/3.4.4/specs Configured with: /gcc/gcc-3.4.4/gcc-3.4.4-1/configure --verbose --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-languages=c,ada,c++,d,f77,java,objc --enable-nls --without-included-gettext --enable-version-specific-runtime-libs --without-x --enable-libgcj --disable-java-awt --with-system-zlib --enable-interpreter --disable-libgcj-debug --enable-threads=posix --enable-java-gc=boehm --disable-win32-registry --enable-sjlj-exceptions --enable-hash-synchronization --enable-libstdcxx-debug : (reconfigured) Thread model: posix gcc version 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) Thank you, -- Nitin Motgi NITIN .

[Review] Formal review of Fixed Strings library starts today
by Hartmut Kaiser 19 Jan '06

19 Jan '06

Hi all, The review of the proposed Boost Fixed Strings library written by Reece Dunn starts today (January 19th, 2006) and ends January 28th, 2006. You can download the library here: http://tinyurl.com/czrh9 --------------------------------------------------- About the library: The fixed_strings library is a buffer-overrun safe version of using fixed-size character array data buffers. It provides integration with the C API allowing strcpy, et. al. to be used safely for a fixed string and provides a basic_string interface allowing easy migration to C++ strings. There is also a formatter function object allowing (w)sprintf to be used in a single line! Example: boost::fixed_string< 5 > hi; strcpy( hi, "Hello World" ); hi.push_back( '!' ); std::cout << hi << std::endl; std::cout << boost::formatter( "Meine %s Welt!", "kleine" ) << std::endl; output: Hello Meine kleine Welt! --------------------------------------------------- Please always state in your review, whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain? Regards Hartmut Review Manager

STL port link error

Hi, I have compiled the boost library for VC7.1 with STL_PORT using the following command line arguments: bjam -"sTOOLS=vc-7_1-stlport" --prefix=C:\Boost\temp install Everything went fine after I have exported the STLPORT_PATH. I create a simple project, code is generated for dynamic runtime lib with the multithreaded option.

Boost Review Wizard's Report: January 2006
by Ronald Garcia 19 Jan '06

19 Jan '06

Review Wizard Status Report for January 2006 Tom Brinkman Ronald Garcia 1) News 2) Review Managers Needed 3) Review Queue 4) Libraries Under Development //////////////////////////////////////////////////////////////////// 1) News //////////////////////////////////////////////////////////////////// Happy New Year! Here are some statistics regarding Boost Library reviews in 2005: - 12 Libraries were reviewed - 8 Libraries were accepted - 1 Library (Function Types) was accepted pending a mini-review - 2 Libraries were rejected - 1 Library has yet to receive a final verdict (ASIO) Policy Pointer has been removed from the review queue because the author has stated that it is not quite ready. We need review managers. Please take a look at the list of libraries in need of managers and check out their descriptions. If you can serve as review manager for any of them, send one of us an email. Note: If you have any suggestions about how we could improve the Review Wizard's status report, please email "reportbase at gmail dot com" and "garcia at cs dot indiana dot edu". //////////////////////////////////////////////////////////////////// 2) Review Managers Needed //////////////////////////////////////////////////////////////////// There are a few libraries in the review queue in need of review managers. If you would like to volunteer to be a review manager, please contact Ron or Tom. The following libraries still require review managers: Fusion Shmem Pimpl Pointer Type Traits (modification) Function Types //////////////////////////////////////////////////////////////////// 3) Review Queue //////////////////////////////////////////////////////////////////// Fixed Strings - January 19 2006 - January 28 2006 Intrusive Containers Function Types (mini-re-review) Shmem Fusion Pimpl Pointer Type Traits (modification) Fixed Strings Author - Reece Dunn Review Manager - Harmut Kaiser Download: Boost Sandbox (http://boost-sandbox.sourceforge.net/) under fixed_string Description: The fixed string library provides buffer overrun protection for static sized strings (char s[ n ]). It provides a C-style string interface for compatibility with C code (for example, porting a C program to C++). There is also a std::string-style interface using a class based on flex_string by Andre Alexandrescu with a few limitations due to the non-resizable nature of the class. Intrusive Containers Author - Olaf Krzikalla Review Manager - to be determined Download: http://people.freenet.de/turtle++/intrusive.zip Description: While intrusive containers were and are widely used in C, they became more and more forgotten in the C++-world due to the presence of the standard containers, which don't support intrusive techniques. Boost.Intrusive not only reintroduces this technique to C++, but also encapsulates the implementation in STL-like interfaces. Hence anyone familiar with standard containers can use intrusive containers with ease. Function Types (mini-re-review) Author - Tobias Schwinger Review Manager - to be determined Download: http://boost-sandbox.sourceforge.net/vault/ Description: This library provides a metaprogramming facility to classify, decompose and synthesize function-, function pointer-, function reference- and member function pointer types. For the purpose of this documentation, these types are collectively referred to as function types (this differs from the standard definition and redefines the term from a programmer's perspective to refer to the most common types that involve functions). The classes introduced by this library shall conform to the concepts of the Boost Metaprogramming library (MPL). The Function Types library enables the user to: * test an arbitrary type for being a function type of specified kind, * inspect properties of function types, * view and modify sub types of an encapsulated function type with MPL Sequence operations, and * synthesize function types. This library supports variadic functions and can be configured to support non-default calling conventions. Shmem Author - Ion Gaztanaga Review Manager - to be determined Download: Boost Sandbox Vault -> Memory (http://boost-sandbox.sourceforge.net/vault/index.php? direction=0&order=&directory=Memory) http://ice.prohosting.com/newfunk/boost/libs/shmem/doc/html/index.html Description: Shmem offers tools to simplify shared memory usage in applications. These include shared memory creation/destruction and synchronization objects. It also implements dynamic allocation of portions of a shared memory segment and an easy way to construct C++ objects in shared memory. Apart from this, Shmem implements a wide range of STL-like containers and allocators that can be safely placed in shared memory, helpful to implement complex shared memory data-bases and other efficient inter-process communications. Fusion Author - Joel de Guzman Review Manager - to be determined Download: http://spirit.sourceforge.net/dl_more/fusion_v2/ Description: Fusion is a library of heterogenous containers and views and algorithms. A set of heterogenous containers (vector, list, set and map) is provided out of the box along with view classes that present various composable views over the data. The containers and views follow a common sequence concept with an underlying iterator concept that binds it all together, suitably making the algorithms fully generic over all sequence types. The architecture is somewhat modeled after MPL which in turn is modeled after STL. It is code-named "fusion" because the library is the "fusion" of compile time metaprogramming with runtime programming. Pimpl Pointer Author - Asger Mangaard Review Manager - to be determined Download: Boost Sandbox (http://boost-consulting.com/vault/) under pimpl_ptr. Description: The pimpl idiom is widely used to reduce compile times and disable code coupling. It does so by moving private parts of a class from the .hpp file to the .cpp file. However, it's implementation can be tricky, and with many pitfalls (especially regarding memory management). The pimpl_ptr library is a single header file, implementing a special policy based smart pointer to greately ease the implementation of the pimpl idiom. Type_Traits (modification) Author - Alexander Nasonov Review Manager - To be determined Download : You can download it from http://cpp-experiment.sourceforge.net/promote-20050917.tar.gz or browse it online http://cpp-experiment.sourceforge.net/promote-20050917/ Description: Proposal to add promote, integral_promotion and floating_point_promotion class templates to type_traits library. Alexander tried it on different compilers with various success: GNU/Linux (gentoo-hardened): gcc 3.3 and 3.4, Intel 7, 8 and 9 Windows: VC7 free compiler Sparc Solaris: Sun C++ 5.3 and 5.7 See comments at the beginning of promote_enum_test.cpp for what is broken. http://cpp-experiment.sourceforge.net/promote-20050917/libs/ type_traits/test/promote_enum_test.cpp Alexander requests a fast-track review. //////////////////////////////////////////////////////////////////// 4) Libraries under development //////////////////////////////////////////////////////////////////// Property Tree Author - Marcin Kalicinski Download: Boost Sandbox Vault (http://boost-consulting.com/vault/) property_tree_rev3.zip Please let us know of any libraries you are currently developing that you intend to submit for review.

boost program_options: change program options

Hi Is there any possibility to posteriorily change the values stored in the options map read from the config file? I.e.: I have assigned the following option: ( "AutomZoneDetect", po::value<std::string>() ->default_value( "off" ), "To detect zones automatically" ); Now I would like to e.g. set this option to "on" at some point in my code...

[multi_array] view-multi_array compatibility in assignments and parameter passing
by Antonio Piccolboni 18 Jan '06

18 Jan '06

I have a 4D multi_array and I define a 3D view on it. I can assign the view to a 3D multi array but I can't pass it directly to a constructor that takes a 3D multi_array. Isn't a 3d view on anything a model of a 3d multi_array? (for the sake of this discussion, element is always double). Code: #include <boost/multi_array.hpp> using namespace boost; class moviva { public: moviva(multi_array<double, 3> m) {} }; main(){ typedef multi_array<double, 4> array_type; typedef array_type::index_range range; multi_array<double, 4> ta4; multi_array<double, 3> ta3; ta3 = ta4[indices[range()][range()][range()][1]]; moviva ma(ta3); // compiles moviva ma1 (ta4[indices[range()][range()][range()][1]]); //does not, line 20 } Compilation view_test.cpp: In function `int main()': view_test.cpp:20: error: no matching function for call to `moviva::moviva( boost::detail::multi_array::multi_array_view<double, 3>)' view_test.cpp:5: error: candidates are: moviva::moviva(const moviva&) view_test.cpp:7: error: moviva::moviva(boost::multi_array<double, 3, std::allocator<double> >) Thanks Antonio

[multi_index][ann][rfc] Preview of Boost.MultiIndex 1.34 release
by Joaquín Mª López Muñoz 18 Jan '06

18 Jan '06

It is a pleasure for me to announce the availability of a preview version of Boost.MultiIndex as planned for shipping with Boost 1.34, downloadable at the Vault: http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directo… (file multi_index.zip) This version includes several important new features: * New random access indices, which behave like sequenced indices with the added benefit of random access semantics. * Rearrange facilities in sequenced and random access indices, allowing for interoperability with external mutating algorithms. This is IMHO an important feature that can open up new usage scenarios for Boost.MultiIndex. * Several optimizations, of which the most important one relates to ordered indices headers, which are now 4 bytes shorter (on 32 bit systems): this optimization also leads to better performance for large numbers of elements. All in all, the upgrade is very extensive, so I'd appreciate if you test if for backwards compatibility even if you don't plan to use the new features. Additionally, I'd greatly welcome receiving any kind of feedback on the new stuff, the docs (which has been restructured and expanded) and whatever aspect you might think can be improved. I plan to commit this new version to the CVS in a couple of weeks or so, so if you have any comments please bring them here now! Thanks very much for your interest in the library, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

<smart_ptr>: A newbie question (about BOOST_SP_USE_QUICK_ALLOCATOR)
by Svaley Streasm 18 Jan '06

18 Jan '06

Hi, I understand that shared_ptr uses the 'quick_allocator' when I compile the library with BOOST_SP_USE_QUICK_ALLOCATOR. But this means that I get the 'quick_allocator' working for every type that I use with shared_ptr, and this bothers me because this seems as a waste of memory for instances of classes that are not frequently used. Besides, the 'quick_allocator' unlike Scott Meyers suggestion (use a pool that can be destroyed) doesn't frees its free blocks which means that, shared_ptr of types that are used only in initialization stage will occupy memory which can not be recycled. Am I missing something? Thank you, Svaley --------------------------------- Yahoo! Photos Ring in the New Year with Photo Calendars. Add photos, events, holidays, whatever.

[posix_time] truncation warning from VC71
by Dale Wilson 18 Jan '06

18 Jan '06

Hi, (possible duplicate, but I think the original was rejected 'cause of a mail alias. If not, please forgive the noise.) I'm using boost 1.32 posix_time in some code that is intended to be portable (MS VC7.1 / Solaris gcc 3.3.1 / RHLinux gcc 3.3.1). When I build with VC 7.1.3088 on Windows XP Pro SP2 get warnings about integer trunction (see below). I can duplicate it by compiling a cpp file containing a single line: #include "boost/date_time/posix_time/posix_time.hpp" and I can work around it by: #ifdef _MSC_VER #pragma warning(push) #pragma warning(disable:4244) // boost/posix_time has truncation warnings #endif // _MSC_VER #include "boost/date_time/posix_time/posix_time.hpp" //include all types plus i/o #ifdef _MSC_VER #pragma warning(pop) #endif // _MSC_VER but this might hide real problems (or this might *BE* a real problem -- I haven't really looked into the difference between a boost::date_time::counted_time_rep<config>::int_type. and a boost::date_time::gregorian_calendar_base<ymd_type_,date_int_type_>::date_int_type Suggestions?

Serialization of static member variables?
by Joseph Turian 17 Jan '06

17 Jan '06

Hi, If see from the serialization documentation that if I serialize a pointer more than once, only one instance will appear in the archive. However, what about static member variables? Will they only be serialized once, even if I serialize multiple objects of the class type? e.g. class foo { private: int i; static int j; friend class boost::serialization::access; template<class Archive> void serialize(Archive& ar, const unsigned int version) { ar & i; ar & j; // Will j be serialized multiple times, i.e. once per foo instance? } }; Thanks, Joseph -- http://www.cs.nyu.edu/~turian/

[serialization] default constructor problem
by Andreas Sæbjørnsen 17 Jan '06

17 Jan '06

Hi, I am currently experimenting with writing a compiler tool which generates the code necessary for using boost::serialization. While working on this I found that I am unable to serialize a variable declaration which is a reference to a class constructed with the default constructor '()'( ex. class foo var(); ). I have tried to find an explanation for this in the examples, documentation and through searching the web without success. Using pointers it works fine with the default constructor and I do not see why it should be any different for references (as references in essence are pointers). Is it possible to serialize a class constructed using the default constructor using boost::serialization, and if so how? Example: #include <fstream> // include headers that implement a archive in simple text format #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> class gps_set { friend class boost::serialization::access; public: int x; gps_set::gps_set(){ x = 2;}; virtual gps_set::~gps_set(){}; gps_set::gps_set(int i) : x(1) {}; private: template<typename Archive> void serialize(Archive& ar, const unsigned int version){ ar& x; }// End method: X::serialization }; int main() { // save the schedule std::ofstream ofs("filename"); // create class instance //Compile time error if s1() is used. No error if s1(1) is used. const gps_set s1(); // save data to archive { boost::archive::text_oarchive oa(ofs); // write class instance to archive oa << s1; // archive and stream closed when destructors are called } }; Thanks, Andreas Saebjoernsen

[mpl] inherit_linearly

I'm trying something new using mpl's inherit_linearly but I can't figure out how to do what I want to do. The idea, simply: template<typename Policies> class Test : public inherit_linearly<Policies, inherit<_1, _2> >::type { public: void do_something(void) { for each Base in Policies Base::do_something(); rof } }; Is there a straightforward way to do this or am I thinking about this in the wrong way? -Dave

Why don't smart pointers have the same semantics as plain pointers?
by Pierre THIERRY 17 Jan '06

17 Jan '06

I use more and more BOOST smart pointers instead of plain pointers in my C++ code, and it is incredible how it saves time and prevent bugs! But I was wondering why one couldn't just change the type of a pointer a keep all code as it is, instead of having to change affectation to reset(), for example. E.g., the following code: Foo* ptr_foo; ptr_foo = new Foo; Has now to be changed to: shared_ptr<Foo> ptr_foo; ptr_foo.reset(new Foo); But I'd like it to be: shared_ptr<Foo> ptr_foo; ptr_foo = new Foo; Is there a problem to have shared_ptr<T>::operator=(T*)?

boost::spirit block of C++ code
by elviin 17 Jan '06

17 Jan '06

I created this parser and it is working for me except the detail: //------------------ //the body of the block cpp_code_block_text = *(anychar_p-ch_p('{')-ch_p('}')); //the code begins with '{' cpp_code_block_begin_p = ch_p('{'); //the code ends with '}' cpp_code_block_end_p = ch_p('}'); //parser: cpp_code_block_p = cpp_code_block_begin_p >> repeat_p (0, 100)[(cpp_code_block_p|cpp_code_block_text)] >> cpp_code_block_end_p; ---------------------- Here is the text I'm using for tests: {asas {bbbbbb bbb b b { asa}bb bbb b bb } as {aaaa} {aaaacc} asasa {} aaa } And the problem is in repeat_p (0, 100). I'd like to use * instead but it does not work for me because the parser runs forever. 100 means the number of blocks cpp_code_block_p or cpp_code_block_text. Where is the problem? Thank you very much for reply.

lvalue error
by Fredrik Wikström 16 Jan '06

16 Jan '06

Hi! I have a polymorphic class in c++ like: class Example { public: void do_something() = 0; void do_something_more {} } This is wrap like: #include <boost/python.hpp> using namespace boost::python; struct ExampleWrap : Example, wrapper<Example> { void do_something() { this->get_override("do_something")(); } }; and finally: BOOST_PYTHON_MODULE(test) { class_<ExampleWrap, boost::noncopyable>("Example") .def("do_something", pure_virtual(&Window::do_something)) .def("do_something_more", &Window::do_something_more) ; } This compiles fine, the python code that work looks like: class Example(test.Example) def do_something(self): ...some code... e = Example() e.do_something_more() The python code that doesn't work looks like: class Example(test.Example) def __init__(self): ..some code... def do_something(self): ...some code... e = Example() e.do_something_more() This generates the error: e.do_something_more() Boost.Python.ArgumentError: Python argument types in Example.do_something_more(Example) did not match C++ signature: do_something_more(Example {lvalue}) How can I fix this? I really need to define a constructor in python class that inherit from the c++ Example class. /Fredrik ----------------------------------------------- This mail was sent through www.lulea.cc

Re: [Boost-users] Pyste/Pyplusplus/Boost documentation problems
by Drumheller, Michael 16 Jan '06

16 Jan '06

(Sorry for the lateness of this response to the notes of Dave Abrahams, Tony Kirke, Stefan Seefeld & Roman Yakovenko.) I asked whether anyone out there gets anything done using Boost.Python *without* using Pyste or pyplusplus, and I said >> It does not seem like a practical thing to do--but maybe I'm missing >> something...? Dave replied: >> Why do you say that? Similarly, Stefan replied: >> I have been using boost.python for a number of projects but I never >> used pyste for any of them. What's wrong with that ? What do you >> think *I* am missing ? (By the way, Stefan: Does your above remark mean you have not tried Pyste, or you tried it and decided to use Boost.Python directly?) To answer your questions: Maybe I *would* just be using Boost.Python directly if I had spent a more time getting used to it at the beginning. But I found that getting even the simplest class hierarchies with virtual functions to work was an error-prone pain in the rear, not to mention a lot of typing. I discovered Pyste at the same time, and tried it, and looked at its output and said, "Wow, I'm glad I didn't have to write all that myself. Who has time for that?" I mean, Pyste's output is by definition a mechanical transformation of my C++ header files--why would I want to perform such a transformation by hand? That's how I got hooked on Pyste. It occurs to me that maybe the reason you do not seem bothered by writing Boost.Python code manually is that you're doing it "minimally," i.e., you're exposing that part (and only that part) of your C++ interface that really needs to be exposed at the Python level. I think I need to revisit my code with this in mind, and I will do that. And/or maybe I can/should just use Pyste as a "bootstrap" mechanism--to generate the *first version* of my Boost.python files, but maintain them manually thereafter. Roman indicates, with this message, <<http://mail.python.org/pipermail/c++-sig/2006-January/010030.html>>, that this is what a lot of people do, but I'm not sure it has really been substantiated. Of course, there is at least one excellent reason for writing Boost.Python wrappers by hand: The longer your tool chain, the more complicated your life. A longer tool chain (i.e., a tool chain with Pyste *and* GCCXML in it) makes it harder for me to sell the hybrid Python/C++ approach to my organization--or even to myself. It is not clear to me what the right balance is between automatic Boost.Python code generation & tool-chain complexity. I'm sure it is project-dependent. I suppose my main suggestion is that the Boost documentation might provide more guidance in making this trade-off. (There is a link to Pyste and that's it. There is no discussion about trade-off or how to address it.) Thanks, Michael

shared_ptr with template class
by Pooyan McSporran 15 Jan '06

15 Jan '06

I'm in the process of converting a large pile of legacy code which uses raw pointers to instead use boost::shared_ptr exclusively. I've got almost all of it converted and working, with one exception. Normally, given a type of Foo I define a smart pointer FooPtr, for example: class Foo; typedef boost::shared_ptr<Foo> FooPtr; But some code uses a templated type, for example: template<typename T> class Foo; Ideally, I'd use a templated typedef, for example: template<typename T> typedef boost::shared_ptr<Foo<T> > FooTPtr; but that is currently illegal in C++. Has anyone found a clean workaround? For now, I'll just do without a typedef in this case :)

Pyste/Pyplusplus/Boost documentation problems
by Drumheller, Michael 15 Jan '06

15 Jan '06

This gmane entry <<http://article.gmane.org/gmane.comp.python.c++/9049/match=pyplusplus+m ature>> says, among other things, the following """If you can, use pyplusplus over pyste. I say that for ALL users of pyste, pyplusplus is now mature enough to be useful as well as being actively developed. It can also do quite a few tricks pyste cannot.""" If this is really the case, I think the Boost documentation needs to say so. For example, the doc page <<http://www.boost.org/libs/python/pyste/>> does not give any warning that Pyste is essentially deprecated (which it apparently is, if the above quote is true). Further, as far as I can tell there are no clues at <<http://www.boost.org/libs/libraries.htm#Inter-language>> indicating that users might want to check out pyplusplus, whereas the official Boost.Python page <<http://www.boost.org/libs/python/doc/index.html>> explicity directs users to Pyste. The end result is that an innocent user who is new to integrating Python and C++ (like, um, say, me) could reasonably come away with the impression that the most state-of-the-art approach to use is Boost.Python+Pyste. As a side question, does anyone use Boost.Python *without* an automatic code generator such as Pyste or Pyplusplus? It does not seem like a practical thing to do--but maybe I'm missing something...? Thank you. Michael D.

Config problem / initial setup
by Greg Buchholz 14 Jan '06

14 Jan '06

Here's what will probably be a really easy question (hopefully it is not too far off topic). I'm trying to get Boost installed on my machine, but I haven't been able to get a working program yet. I downloaded the "bjam" program and the source for the libraries. Performing the 'bjam "-sTOOLS=gcc" install' as recommended by the "Getting Started Guide" seemed to run smoothly. (and I can't find any logs in the build directory which which would tell me differently). So next I tried to compile an example program from Regex... http://www.boost.org/libs/regex/example/snippets/credit_card_example.cpp ...this initially failed with a message complaining about "boost/regex.hpp" not being found. So I added an additional include search path... g++ -I /usr/local/include/boost-1_33_1/ credit_card_example.cpp ...this works fine until the linker gets invoked... > /tmp/ccagNJn9.o(.gnu.linkonce.t._ZN5boost11regex_matchIN9__gnu_cxx17__ > : undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__ > collect2: ld returned 1 exit status ...etc. So it looks like it can't find the libraries to link against. But my /usr/local/lib directory has all sorts of libboost* files, including libboost_regex-gcc.so and friends. I've tried a number of other g++ options including "-lboost", "-llibboost", "-llibboost_regex", and "-llibboost_regex-gcc". Any hints on what I might try to get things up and running? My system is Slackware Linux 9.1 and gcc 3.4.2. Thanks, Greg Buchholz

[Serialization] Many similar looking types

Hello, I have to serialize some classes that look like this : struct A { vector<Base*> v; Base* get(int i); }; struct B1: A { Derived1* get(int i); }; ... struct B1000 : A { Derived1000* get(int i); }; (well, not exactly 1000, but definitively more than a couple, and no, I cannot change this design). I would like not to add serialization code to all of thoses classes, just to the base class, since all those classes are almost the same. Is this possible ? If I do not define anything for Bn classes, I get some archive_exception::unregistered_class exception. Regards, -- Loïc

[iostreams] implementing an xdr streams
by Jeff Flinn 13 Jan '06

13 Jan '06

I've looked at Jack Reeves' XDRStream code from earlier CUJ articles. I've tested his code which seems extract values properly, but has problems with tellg, seekg, ... returning incorrect values and corrupting the stream state. This seems like an ideal application for the iostreams library. JR's implementation is based on an XDR_CHAR 32 bit character type. Any thoughts on whether this is the ideal approach? Any guidance on design directions would be appreciated. Thanks, Jeff

Re: [Boost-users] [test] How do you create test cases in a DLL
by Stewart Tootill 13 Jan '06

13 Jan '06

This may not help, and may not be the right way to go about it, but typically I get around this by putting all of the internal bits into a static lib, then linking that into the test binary. This also means that when I link the DLL, the test bits are left out, so I don't have to ship alot of redundant test code which the unused testInternals export would cause to be included in the final DLL. Admitedly, my DLLs are designed to be built in this way.. -----Original Message----- From: boost-users-bounces(a)lists.boost.org [mailto:boost-users-bounces@lists.boost.org]On Behalf Of Mark Snelling Sent: 12 January 2006 17:53 To: boost-users(a)lists.boost.org Subject: [Boost-users] [test] How do you create test cases in a DLL I have some internal (non-exported) classes in a DLL that I want to test. I'm trying to do this by exporting a testInternals() function that my tester application will add to it's test suite. The problem I'm having is that to use any of the BOOST_CHECK_??? etc macros I have to include the <boost/test/test_tools.hpp> file. This causes undefined symbol linker errors. Is there a way to do what I want to do? ________________________________________________________________________ This e-mail has been scanned for viruses by MessageLabs. ________________________________________________________________________ This e-mail has been scanned for viruses by MessageLabs.

I'll hang loose for the moment then! I will go back to 33.0 to see if that compiles cleanly for arm (and post any significent resutls), and in the meantime keep an eye on things here for any news.

Assertion failure usign boost::format with Visual C++ 2005
by Jean-Sébastien Otis 12 Jan '06

12 Jan '06

Hello, Here is a sample that generates an assertion failure with Visual C++ 2005 using boost 1.33.1. A NULL ptr is passed to std::string::append() by boost::io::detail::mk_str(). //////////////////////////////////////////////////////////////////// #include <boost/format.hpp> int main(int argc, char* argv[]) { std::string str(""); // Empty string. boost::format frmt( "%s" ); std::string res = ( frmt % str ).str(); return 0; } //////////////////////////////////////////////////////////////////// This is due to all the assert statements added in the new "secure" STL that is shipped with VC2005. But still, I don't think passing NULL to string::append() is correct anyway... Regards. J.S.Otis Software Developper InnovMetric Software Inc.

[Boost.Build v2] vc 8.0 manifest problem
by Jaroslav Gresula 12 Jan '06

12 Jan '06

Running bjam.exe on the Jamroot listed below gives bin\msvc-8.0\debug\runtime-link-static\shared.dll.manifest : general error c1010070: Failed to load and parse the manifest. The system cannot find the file specified. <Jamroot> using msvc : 8.0 ; lib shared : file.cxx : <link>shared <runtime-link>static ; </Jamroot> I've noticed that removing <runtime-link>static or replacing it with <runtime-link>shared 'fixes' the problem. I use Boost.Build from the Boost CVS and MSVC 8.0 Professional Edition. -- Jarda

boost::gregorian::months : access value / serialize
by Oliver.Kowalke＠infineon.com 12 Jan '06

12 Jan '06

Hallo, I've to serialize the value of months into a databse. This requires to access the value (amount of months) stored inside of boost::gregorian::months. How can I access the internal value (nothing found in the docu)? If this is not possible which boost::date_time type should I in order to store a datetime duration consisting of the pair years and months (Oracle database type INTERVAL YEAR TO MONTH)? Regards, Oliver

Re: [Boost-users] Cross compiling boost libraries with gcc and using boost jam to crosscompile third-party library (Jambase problem)

I then used "-sGXX=m68k-elf-g++ -sGCC=m68k-elf-gcc -sAR=m68k-elf-ar" on my build command line. Additionally, I added support for selecting the CPU model (architecture/instruction-set) by adding the following: (I don't know how/why this works, just imitated the respective block for other architectures). Perhaps, boost build system should support (kind of) multilib builds for cross compilation, in a similar way that gcc/g++ does when cross-compiling it for targets where this applies? This enabled me to add "-sBUILD=debug release <runtime-link>static <optimization>size <architecture>m68k <instruction-set>5200" to the build command line for a Coldfire cross-build. It even somehow worked, as gcc got called with the correct -m option... # Coldfire and other m68k (WS, Tue Dec 20 16:46:10 2005). .ARCH = <architecture>m68k <architecture>native ; flags gcc CFLAGS <architecture>m68k/<instruction-set>default : -m5200 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>68000 : -m68000 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5200 : -m5200 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5206e : -m5206e ; flags gcc CFLAGS <architecture>m68k/<instruction-set>528x : -m528x ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5307 : -m5307 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5407 : -m5407 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>cpu32 : -mcpu32 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>68040 : -m68040 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>68060 : -m68060 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>soft-float : -msoft-float ; >So I've done a small patch to tools/build/v1/gcc-tools.jam adding >GCC_PREFIX variable, that if set up, will prefix names of all tools with >that prefix. > >So I can compile boost with > >bjam -sTOOLS=gcc -sGCC_PREFIX=arm-linux- stage > > Ah, your approach with using GCC_PREFIX is even better!

But I don't know or use jam or bjam (other than building (parts of) boost itself), so unfortunately I would be of little help... :-( I replied to the post becuase somone else might find the information helpful as well, I hope. >By the way, the same problem appears when boost jam is used to compile >some third-party libraries.
