boost::lambda::bind - a better name?
by Maciek Godek 10 Jul '07

10 Jul '07

Wouldn't it be better if boost::lambda::bind was named boost::lambda::call (or boost::lambda::eval, to make it more lispish), in order to: -avoid the confusion and potential overlap with boost::bind -make the name more sensible within lambda expressions, especially when "binding" nullary functions, ie. int six() { return 6; } if_(call(six) == 6) [ ... ] IMHO looks better than if_(bind(six) == 6) [ ... ] Yours, Chuj

boost::lambda library, error with << operator (on g++ with SGI STL)
by Maciek Godek 10 Jul '07

10 Jul '07

Hi, I've tried to compile the following code on linux/g++ (version 3.3.4 and 4.1.2), boost version 1.34: -- CODE BEGINS -- #include <iostream> using namespace std; #include "boost/function.hpp" #include "boost/ref.hpp" using namespace boost; #include "boost/lambda/lambda.hpp" #include "boost/lambda/bind.hpp" #include "boost/lambda/if.hpp" using namespace boost::lambda; int main(int argc, char *argv[]) { function<void (int, int)> f = if_(_1 == _2) [ cout << cref("arguments are equal\n") ].else_[ cout << cref("arguments differ\n") ]; f(1, 1); f(1, 2); } -- CODE ENDS -- On g++ 3.3.4 I got a (scarcely readable) error that std::ios_base copy constructor is private (the more recent compiler gave much more trashy output, but I've infered that the reason is probably the same). The error wouldn't appear if I had supplied at least one placeholder to the operator<< in both if's cases in the lambda expression above. Is there any way to overcome this limitation?

Does boost offer a random permutation function?
by Jeffrey Holle 09 Jul '07

09 Jul '07

I am looking for a function that randomly selects a permutation of a sequence. For instance given "1,2,3", it would produce something like "2,1,3" randomly selected from all possible permutations. I could code this myself by creating a container with all possible permutations and randomly selecting one, but this isn't reasonably if the size of the sequence gets larger. I've looked on the web and found an old 4 line FORTRAN subroutine that appears to do this. If boost don't already have this, I will attempt to convert this to C++.

[Boost.Python] Issues When Object Created in C++ and Then Used From Python
by Lawrence Spector 09 Jul '07

09 Jul '07

I created an example of code that demonstrates the error. Here's what the code looks like, as of right now: PythonPassReference.cpp: #include <boost/python.hpp> #include "TestClass.hpp" #include "TestClassWrap.hpp" #include <iostream> using namespace boost::python; int main() { try { Py_Initialize(); object main_module(( handle<>(borrowed(PyImport_AddModule("__main__"))))); object main_namespace = main_module.attr("__dict__"); TestClass testClass(std::cout, 3, 9.6f, 'Q'); { handle<> ignored((PyRun_String( "import PythonInterface" , Py_file_input , main_namespace.ptr() , main_namespace.ptr()) )); } TestClassWrap testClassWrapper(testClass); boost::python::object pyTestClass(testClassWrapper); // Works: pyTestClass.attr("output")(); { handle<> ignored((PyRun_String( // Works: "pyTestClass = PythonInterface.TestClass(6, 8.3, 'W')\n" "pyTestClass.output()\n" // Error unless the previous line is uncommented , Py_file_input , main_namespace.ptr() , main_namespace.ptr()) )); } } catch(boost::python::error_already_set& e) { std::cerr << "Caught error_already_set" << std::endl; if (PyErr_Occurred() != 0) { PyErr_Print(); } // end if } catch(...) { std::cerr << "Caught unknown error" << std::endl; } // end try-catch std::cin.get(); return 0; } // end main TestClass.hpp: #pragma once #include <iostream> class TestClass { private: std::ostream& m_outStream; int m_x; float m_y; char m_z; public: TestClass(std::ostream& p_outStream, int p_x, float p_y, char p_z) : m_outStream(p_outStream), m_x(p_x), m_y(p_y), m_z(p_z) { } // end TestClass ~TestClass() { } // end TestClass void output() { m_outStream << "x = " << m_x << ", y = " << m_y << ", z = " << m_z << "\n"; } // end callMethod }; // end TestClass TestClassWrap.hpp: #pragma once #include "TestClass.hpp" class TestClassWrap { private: TestClass m_testClass; public: TestClassWrap(const TestClass& p_testClass) : m_testClass(p_testClass) { } // end TestClassWrap TestClassWrap(int p_x, float p_y, char p_z) : m_testClass(std::cout, p_x, p_y, p_z) { } // end TestClass ~TestClassWrap() { } // end TestClass void output() { m_testClass.output(); } // end callMethod }; // end TestClassWrap PythonInterface.cpp (Built with BJam, makes PythonInterface.pyd, PythonInterface.lib): #include <string> #include <boost/python.hpp> #include <iostream> #include "TestClass.hpp" #include "TestClassWrap.hpp" using namespace boost::python; BOOST_PYTHON_MODULE(PythonInterface) { class_<TestClassWrap>("TestClass", init<int, float, char>()) .def("output", &TestClassWrap::output) ; } // end module As you can see in the example above, I have an object which I wrap and then pass to python as follows: TestClassWrap testClassWrapper(testClass); boost::python::object pyTestClass(testClassWrapper); This works just fine, and I can call methods on the object. However, when I try to run it as a string (as it would be if read from a .py script file), I get an error. Here's the code for that: { handle<> ignored((PyRun_String( "pyTestClass.output()\n" // Error unless the previous line is uncommented , Py_file_input , main_namespace.ptr() , main_namespace.ptr()) )); } Which produces the following error (based on my catching and outputting the error): Caught error_already_set Traceback (most recent call last): File "<string>", line 1, in <module> NameError: name 'pyTestClass' is not defined So, I guess the question is, how do I expose an instance called pyTestClass, in such a way, that I can call methods on it from a script? Or is there some mistake I'm making, that's preventing this from fully working? Thanks in advance, Lawrence

Réf. : [boost] Réf. : Re: [filesystem] building for cygwin
by frederic.bron＠alcan.com 09 Jul '07

09 Jul '07

Finally, I had a close look inside filesystem files and I discovered that to compile for cygwin 2 flags must be set: BOOST_POSIX_API and BOOST_POSIX_PATH! If only BOOST_POSIX_API, BOOST_WINDOWS_PATH is set automatically. Why??? This is a strange behaviour. Then: - either change the doc and add that for cygwin compilation, BOOST_POSIX_PATH must be set as BOOST_POSIX_API, - or change filesystem/config.hpp so that BOOST_POSIX_PATH is automatically set when BOOST_POSIX_API is set (I would prefer this solution).

[mpi] shared_ptr + packed_iarchive
by Andras Joo 09 Jul '07

09 Jul '07

Dear All, I'm facing the following problem. I have the following class hierarchy: AbstractBase <--- AbstractDerived <---- ConcreteDerived I managed to make the serialization of shared_ptr<AbstractBase> using text and binary archives (text_[i/o]archive, binary_[i/o]archive), tested, and works fine. However, when I try to send an shared_ptr<AbstractBase> with some MPI function, the compiler complains about packed_iarchive not having append() and reset() functions. /home/jooam/usr/include/boost-1_35/boost/serialization/shared_ptr.hpp:129: error: 'class boost::mpi::packed_iarchive' has no member named 'append' /home/jooam/usr/include/boost-1_35/boost/serialization/shared_ptr.hpp:137: error: 'class boost::mpi::packed_iarchive' has no member named 'reset' Any help is appreciated.

09 Jul '07

Hi Everyone: I use boost 1.3.3.1 and stlport in my project,actually Boost::regex is my need. If I compile my project without include boost files in project settings,it's ok and of course cl told me that it can't find some header files such as regex.hpp . But if I add boost path into my project settings,the compiler will threw some erro just like below: BoostRegHandler.cpp D:\SyncSdk\include/stlport\cstddef(35) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information Error executing cl.exe. I have no idea on this,does anyone compile your project with boost & stlport successfully? Or is there any seetings error of my project. BTW:I use vc6.0 , XP proffessional ,Intel P4 2.0 512 RAM Hongquan

Objects serialized > through pointers are tracked by default. Your "ResourceID" seems a > re-implemenation of the "object id" used by the serialization libary > to track This is true, but the serialization libraries view of the id's only have archive scope, which means the same id's are used for totally different things when you use multiple archives. My ResourceID's have to be globally unique, in the sense they are GUIDs or relative pathnames, which can then be mapped to a fully qualified pathname and can be loaded on demand. As far as the archive class is concerned its a user defined translation (proxy-to-real and real-to-proxy) that exists for certain types. So in this case its conceptually an archive of archives. With the outermost archive being the filesystem, and the innermost being a single object (a file). The file only contains one object, and all links to other objects are handles (a filename). So the innermost code when it is loading from the filesystem, it knows that it wants a pointer to another object, but it only has its name. So it has to ask the filesystem class to translate the name into an object, which it can do because it can lookup if its already loaded and return that, or literally open another file based archive and read it in on demand, and return that. The archive class doesn't care about the specifics really, it just needs the means to achieve the result. So the archive's base class code should be doing this in a conceptual way: for_each type X, if has_user_defined_translation<X*> implement : on_save -> translate type X* to type ProxyX via a function : ProxyX RealToProxy(X* x), serialize the ProxyX on_load -> read ProxyX translate to X*, via a function : X* ProxyToReal(ProxyX& px), return the X* Except that this on_save and on_load example needs to have yet another template argument, on whether the first occurence of X should be literally saved or not, since we might be saving a hierarchy of Bar's that always save handles to Foo's at all times. > > > ... > > > > I also have to hard-code the full list of derived Asset types and > > manually provide specializations for all of them in save_override and > > load_override. > > > **** > Well, since they're different - I would expect each of them to have a > different serialize function.

In my currently kind-of-working hacked up version of the archive classes the methods load_override are nearly identical when specializing for AssetModel, AssetTexture, etc. The behavior is constant (proxy-to-real translation or vice-versa) but the type is not. I can slice them here safely on saving, but not on loading (since the C++ code in the serialize method 'ar & foo', is expecting a more-derived type to be filled in). > I can't make serialize virtual, since the intrusive serialize methods > > are templates, but it certainly would solve the problem if it were > > possible. > > *** > I suspect that if the other changes suggested were implemented this > would disappear as a problem.

That isn't possible with learning new code :) This is what the path of least resistance yielded, with the docs and examples provided by boost. Basically this is as far as I got without having to directly hack on the existing boost code, and having to deal with a crash course on the code flow and internal data structure of everything. > > > *** me this is exactly the wrong approach.

The library can do what I want, because I have the source code :) Anyway the classes aren't coupled to the archive with what I've come up with so far, its the other way around. I definitely do not want my classes to understand archiving beyond a very basic sense of having to call operator& on most of their fields, since I plan on having several wildly different archive classes calling the serialize methods on my classes.

I could also template specialize the serialize methods for the archive in question, but then I would have to write more than one. Its the archives job to interpret what to do when you call ar & foo. I anticipate having more data than I can load, so I need to load and save at an object level. But I still need to write the serialize methods as if they all could fit in memory, since I plan on having other archive classes that do operate on the graph of what is loaded at runtime (i.e. to compute garbage collection). In essence the archive classes need to be made to be programmable for these behaviors to work: Graph of Foo: Saving: save the first Foo*, translate all further Foo*'s into a user defined handle with a user defined function and save that instead. Loading: load the first Foo*, assume all further Foo*'s are saved with a user defined handle, translate them back into live objects on demand, and also use the existing caching scheme to prevent having to translate the same user-defined handle over and over. Graph of Bar: Saving: save all Bar's, but save all occurences of Foo*'s as handles Loading: save all Bar's, but load all occurences of Foo*'s from handles Garbage Collecting Foo: 'Saving' : archive an array of live root level Foo objects, build a list of all Foo* that are reachable through serialization. Compare this list to the full list of Foo objects, and unload the ones that are missing.

non-boost: project idea help. Java expert apperciated.
by chun ping wang 08 Jul '07

08 Jul '07

Dear boost community. Right now I am planning on doing somewhat of a mock boost for java. http://cs.calstatela.edu/wiki/index.php/Current_MS_Students/Chun_ping_Wang. I am not going to use the name boost but i want to know a.) a good name for it. b.) five common non-ui files you think Java needs that it is missing. All implementation can be done using low level arrays and iterators (if needed). Thanks

[boost.python] How to get derived class from base class in Python?
by Marcin Kalicinski 08 Jul '07

08 Jul '07

This may potentially be unrelated to Boost.Python, but how to do an equivalent of C++ dynamic_cast in Python, having all the classes wrapped using boost.python? See below: // All the components inherit from Component class Component { }; class ComponentA: public Component { }; class ComponentB: public Component { }; // Find a component by name Component *FindComponent(const char *name); // In C++ result of FindComponent may be dynamic_casted to appropriate type: void f() { Component *c = FindComponent("a"); ComponentA *a = dynamic_cast<ComponentA *>(c); } How to do this in Python (all Component classes are wrapped)? def f(): c = FindComponent("a") # Unforunately Python sees c as an instance of Component, not as ComponentA which it really is a = ??? Thanks, Marcin

Re: [Boost-users] [Serialization] link errors serializing user types via pointer
by Sean Cavanaugh 08 Jul '07

08 Jul '07

Ok well in trying to get the serialization library working on my environment, I am having trouble loading user types via pointer. I've simplifed the class in question down to a struct containing PODs. Changing the trivial example to save and load via a local stack variable (i.e. ar & pass-by-reference) does work, however the real program I am trying to save a graph of structures foo with pointers to bar, I'm back to the original link error when trying to load the graph back, even when the root type passed into serialize is a reference type.

Grabbing web page content
by Scott Meyers 07 Jul '07

07 Jul '07

I'm looking for an easy way to grab the contents of a web page, i.e., something like this (ignoring error handling): std::string pageContent = getPageContent("http://www.interestingsite.com/funkypage.html"); Is there a Boost library that will give me this kind of interface? I know I can build this on top of asio, but I'd prefer something where I don't have to do much more work than the above. If there's no Boost library, I'd welcome suggestions for other cross-platform ways to achieve this. Thanks, Scott

[filesystem] building for cygwin
by frederic.bron＠alcan.com 07 Jul '07

07 Jul '07

In the documentation, it is written what follows for compiling with cygwin. Basically set BOOST_POSIX_API when building for cygwin and BOOST_WINDOWS_API when building for windows (i.e. -mno-cygwin). My question is: how to set BOOST_POSIX_API in user-config.jam? I have tried <define>BOOST_POSIX_API but it did not work. I have tried <cflags>-DBOOST_POSIX_API <cxxflags>-DBOOST_POSIX_API... and the -DBOOST_POSIX_API is given to g++ but I still have the windows behaviour. For example cout << boost::filesystem::path("/cygdrive/c/toto").file_string() ; gives \cygdrive\c\toto. Can you help to get the POSIX behaviour when compiling without "-mno-cygwin"? Regards, F. Bron The library's implementation code automatically detects the current platform, and compiles the POSIX or Windows implementation code accordingly. Automatic platform detection during object library compilation can be overridden by defining either BOOST_POSIX_API or BOOST_WINDOWS_API macros. With the exception of the Cygwin environment, there is usually no reason to define these macros, as the software development kits supplied with most compilers only support a single platform. The Cygwin package of tools supports traditional Windows usage, but also provides an emulation layer and other tools which can be used to make Windows act as Linux (and thus POSIX), and provide the Linux look-and-feel. GCC is usually the compiler of choice in this environment, as it can be installed via the Cygwin install process. Other compilers can also use the Cygwin emulation of POSIX, at least in theory. Those wishing to use the Cygwin POSIX emulation layer should define the BOOST_POSIX_API macro when compiling bother user programs and the Boost.Filesystem's object-library.

[Boost.Graph] Property map of a bundled property
by Ewgenij Sokolovski 07 Jul '07

07 Jul '07

Hello, I want to apply dijkstra_shortest_paths to my Graph. I have added the lengths of the edges with while adding the edges with the function add_edge(vi, vj, distance, *nodesGraph) where vi, vj are the vertex descriptors, distance is the length of the edge and nodesGraph is a pointer to my graph. Now I need to provide an appropriate property map for the bundled property "distance". In the manual I read that I have to provide a member pointer to the property value: file:///usr/share/doc/packages/boost-doc/libs/graph/doc/bundles.html But in my case I do not have a class with members like 'Highway' in the manual. In my case the bundled property is represented by a single float value. And so I need access to it, not to some members of it. I tried to write weight_map(get(&float, myGraph)) instead of weight_map(get(&Highway::miles, map)) in the example, but then I get a compiler message "expected primary expression before "," token". So how can I access the distance? Or comes the compiler message due to some other bug in my code? Ewgenij -- Psssst! Schon vom neuen GMX MultiMessenger gehört?

[serialization] DLL woes
by Anders Wang Kristensen 07 Jul '07

07 Jul '07

Hi, I'm trying to serialize a class using two functions located in different DLLs. I can serialize fine by calling one function, but when I call the second it triggers an assertion in extended_type_info.cpp: // make sure that attempt at registration is done only once assert(lookup(eti) == m_self->m_map.end()); Apparently the class is registered twice, but how do I avoid that? -- Anders

[Graph] I could not get the reversed graph!
by jiangfan shi 06 Jul '07

06 Jul '07

HI, All, I could not get a instance of reversed graph by calling make_reverse_graph(g). That is, I have following type: typedef adjacency_list< listS, listS, bidirectionalS, property<vertex_index_t, std::size_t>, no_property> G; typedef reverse_graph<G, G&> ReverseG; //Maybe something wrong here. After I call make_revserse_graph(G) as following, I could not get a instance of modified graph by accessing some fields of ReverseG. ReverseG tmp=boost::make_reverse_graph(g); //I try to get the reservsed graph here. The only field is tmp.m_g, which is G& type and the original graph, but is not the reversed graph. Thanks.

Python rules for compiling in Mac OS X
by Antony Chazapis 06 Jul '07

06 Jul '07

Hi all. It seems that the tools/build/v2/tools/python.jam file is broken when used in Mac OS X (darwin). I had many problems when trying to compile libtorrent's python bindings using bjam and they all were finally solved by changing this file. I would suggest applying the following patch to the code. This fixes the missing "python_for_extensions" rule problem, and allows for properly setting the include paths (without relying on env vars). For linking I just used "-framework Python". I don't get what all the $ (PYTHON_FRAMEWORK) stuff is about. With the "official" python install, gcc automatically finds the framework. However, there is still an issue: In rule "init-mac" the "root" variable should not be necessary. When I tried to change that, compilation broke again. I guess there are references to the variable elsewhere that have to be changed first. For now I can compile everything by setting (in user-config.jam): using python : 2.5 : /Library/Frameworks/Python.framework/Versions/2.5 ; Hope this helps, as it should apply to other python-related projects as well. Antony

[1.34][fusion] tuple_size doesn't work anymore
by Christian Henning 06 Jul '07

06 Jul '07

Hi there, in the process of recompiling my project with boost 1.34. it seems that tuple_size doesn't work for long tuples anymore. The following code used to work: #define FUSION_MAX_MAP_SIZE 20 #define FUSION_MAX_VECTOR_SIZE 20 #include <boost/fusion/sequence.hpp> #include <boost/fusion/tuple.hpp> struct A { typedef boost::fusion::vector< int , int , int , int , int , int , int , int , int , int , int , int > type; static const std::size_t table_size = boost::fusion::tuple_size<type>::value; }; int main() { return 0; } The code does compile when the number of parameters is 10 or less. Any ideas? Christian

wrapping stdlib fstream with boost filtering streams
by Daniel Oberhoff 06 Jul '07

06 Jul '07

Hi, I have a homebrewed matlab file library for which I am considering using the boost filtering streams for zlib compression. In Matlab(tm) files, variables may be compressed individually, meaning there will be compressed blocks inside the file surrounded by umcompressed data. Thus I would like to have (de)compressors which I can plug in at the start of the block and take back out when I am done. I went and applied the boost filtering streams but I have some problems, so before I go into hardcore debugging I would like to ask if I am using the lib right (because the docs are a bit sparse at the relevant spots). This is how I start up the stream(s): File::File(std::string path, std::ios_base::openmode mode) : _fstream(path.c_str(), mode | std::ios_base::binary) { if (!_fstream.is_open()) throw_error("could not open matfile " << path); _istream.set_auto_close(false); _ostream.set_auto_close(false); _istream.push(_fstream); _ostream.push(_fstream); } and these are the methods for starting/stopping the compressed blocks for reading/writing: void File::startunzipping(std::streampos len) { stopunzipping(); _unzend = _fstream.tellg() + len; _unzcount = 0; _istream.pop(); _istream.push(boost::iostreams::zlib_decompressor()); _istream.push(_fstream); _unzipping = true; } void File::stopunzipping() { if (_unzipping==false) return; _istream.pop(); _istream.pop(); _istream.push(_fstream); _unzipping = false; _fstream.seekg(_unzend); } void File::startzipping() { stopzipping(); write_type_and_size(TypeAndSize(Types::Compressed,0),false); _zstart = _fstream.tellp(); _zcount = 0; _ostream.pop(); _ostream.push(boost::iostreams::zlib_compressor()); _ostream.push(_fstream); _zipping = true; } void File::stopzipping() { if (_zipping==false) return; _ostream.flush(); _ostream.pop(); _ostream.pop(); _ostream.push(_fstream); _zipping = false; _zend = _fstream.tellp(); } Two open questions that come to mind: 1) does the compressor flush the zlib compression buffer when I flush/ pop it? 2) is fstream a bidirectional stream (my guess due to separate seekg/ seekp methods) or a seekable stream (one read/write head)? Because I currently require the former. btw: the above code runs without exceptions, but when I read back variables I have just written they are garbled.

[asio] File I/O
by William Kemper 05 Jul '07

05 Jul '07

I know I'm not the first person to bring this up and it seems that some work has been done: http://lists.boost.org/Archives/boost/2006/03/102350.php . Does anybody know if Felipe has posted his code somewhere? Or when we might an implementation of asynchronous file I/O in asio itself? Failing that - is there some class in the library (or examples) which would be a suitable starting point or reference/guide for creating a non-socket asynchronous I/O service? Thanks in advance.

[Boost-user]multithreaded app hangs in boost libraries
by Farberov, Inga 05 Jul '07

05 Jul '07

Hello, I have written a static library that uses boost program_options, threads, date-time and serialization libraries. There is also an extensive use of shared_ptr. I am working on a multithreaded application, so when I link my library into the executable, I use multithreaded versions of the boost libraries. When I compile my library and application that links to it, I use -pthread flag in attempt to make it multi-threaded. Everything compiles and links without a problem, however when I try to run the application, it hangs. I have tried to bedug it and when I suspend a hanging thread it gives me following stack trace: 18 _dl_sysinfo_int80() 0x003317a2 17 __lll_mutex_lock_wait() 0x0062e30e 16 _L_mutex_lock_35() 0x0062af3b 15 <symbol is not available> 0x080c80e8 14 <symbol is not available> 0x00472ff4 13 <symbol is not available> 0x080c80e8 12 <symbol is not available> 0xbffff6b0 11 <symbol is not available> 0xbffff208 10 pthread_mutex_lock() 0x0042097e 9 pthread_mutex_lock() 0x0042097e 8 scoped_lock() /usr/include/boost/detail/lwm_pthreads.hpp:72 0x080598eb 7 boost::detail::sp_counted_base::add_ref_copy() /usr/include/boost/detail/shared_count.hpp:122 0x0805b679 6 shared_count() /usr/lib/boost/include/boost-1_34/boost/detail/shared_count.hpp:216 0x0805b65b 5 shared_ptr() /usr/include/c++/3.4.6/bits/stl_construct.h:81 0x0807a7c8 4 boost::program_options::options_description_easy_init::operator() libs/program_options/src/options_description.cpp:178 0xb7fd7189 3 Settings() ../Settings.cpp:9 0x08081808 If this post sounds familiar, that's because this is my second attempt to get this problem resolved. Previously I have been told that this sounds like I've built my application with single-threading, and linked it to multi-threaded build of a boost library, or vice versa. Could you please let me know what's the right way to build my app with multi-threading. I am using Boost 1.34 libraries on Linux and compile with gcc 3.4.6 Thank you in advance for your help, Inga

Hi all, here is my code: #define BOOST_AUTO_TEST_MAIN #include <boost/test/auto_unit_test.hpp> BOOST_AUTO_TEST_CASE( test1 ) { BOOST_CHECK(true); } I link it dynamically with boost ver 1.3.3.1 with gcc-3.4.4 on Linux 2.6. (Note I did not compile this library myself.) However there is a lot of other libraries linked to the module but never used. Bellow is output I am getting. I suspect that other libraries have embedded boost tests. BUT 1) There is no test1 in my output. 2) How I can remove all unnecessary test and stick only to those in my files only?

[Serialization] serializing handles to pointers, and serializing as garbage collection
by Sean Cavanaugh 05 Jul '07

05 Jul '07

I'm a bit new to boost and am trying to determine if I can coax the existing boost serialization system to work for a fairly standard asset loading system. Assets in my domain of game programming are things such as bitmaps, model geometry, audio data, shaders, and various chunks of meta data attached to them. The quantity of such data should always be assumed to vastly exceed the ability to load it all at once, which means getting sneaky when dealing with persistence. From my point of view the boost::serialization code is missing a lot of important features, so I am kind of surprised that they are not there. A) Serializing for persistence: Assets can reference other assets via pointers, but serializing for persistence should only store names of other assets, and query a resource manager to help convert the pointer into a name (or vice versa). A model object might reference via a pointer a shader and a texture in addition to its geometric data. When I serialize the model for persistence I want to store the geometric data, but when it comes to the shader and textures I only want to store their names. I could manually do this in each method's serialize methods. However the serialization system should also be able to do this via type traits, so that I don't have to hack up the serialize methods. The type trait method for this is preferable, since the method bodies of serialize could then be written as the originally would want to be, so that completely different kinds of archivers can operate on them, especially ones that depend on actually being able to walk into the pointers. Its the archive's call how to walk the data really. B) Serializing for garbage collection: A full set of raw assets for an engine can easily push into the terabyte range, which means you never actually work with all of the data at once. To work you need to be able to load what you need as you go, but to keep your working set down you need to evict unused assets as much as possible. Another type trait could be used to build a list of reachable objects containing the type trait from an array of root objects which are serialized. You can then compare this list to the full list of what the resource manager has currently loaded, and either delete or save the modified but now unreachable nodes. This system has the advantage of being useful for other purposes, such as making making an asset browser, without having to also implement a full blown system for reflection and introspection. C) Serializing for counting memory: You can also make the archive simply count the memory overhead of your objects. It needs the ability to count memory without counting the memory twice, and it also needs to be able to either do this for a single object (i.e. don't follow reference to other assets), or for a hierarchy (i.e. 'how much memory does using this asset require, factoring in its dependencies'). So my real question boils down to : I can't really be the first person to want it to be able to do these things right? Am I crazy for wanting to coax the boost serialization code into working this way?

Can you please describe a bit more? How do you start your threads (before your app enters main or from the main)? Is there any chance, that you create threads and afterwards leave main? Try to build in some simple logging mechanism, which will produce logs to cout from your threads and main as well... Do not forget to lock access to cout. Try may be create an instance of a global object, which will output log message from its constructor.

[tuples] How to impose external allocator onto a class?
by Zeljko Vrba 05 Jul '07

05 Jul '07

I want to define custom new and delete operators for tuples. The usual way to do it would be, I presume, to derive from a base class and define these operators in the derived class. However, doing this for tuples would require me to provide all possible templated derivations for up to 10 arguments, including constructors. (And then maybe even defining new make_tuple functions). Is there a better way to accomplish this task?

[serialization] bad alloc and deserialization
by Cyril 05 Jul '07

05 Jul '07

Hello all, I have some trouble using boost::serialization : this code ============== try { std::stringstream erroneousStream; erroneousStream << "not a message ! @@@"; boost::archive::text_iarchive input(erroneousStream); Message* deserializedMessage; input >> deserializedMessage; // failure } catch (boost::archive::archive_exception& e){ std::cerr << e.what() << std::endl; } catch (std::exception& e) { std::cerr << e.what () << std::endl; } catch(...) { failmsg("unexpected !"); } =============== fails with a bad alloc exception. I don't think this is a normal behavior. So, what can I do to make this code fail correctly (with an archive_exception or even better with a serialization_exception) ? I must precise that in a normal scenario (with a real serialized message, this works perfectly well ! Any other idea ? Tanks in advance for you answers.

[Boost-docs] [Improving Boost Docs] Help Request, Request for Testers
by Stuart Dootson 05 Jul '07

05 Jul '07

As many of you will be aware, Matias Capeletto has been working at improving the Boost documentation in various ways, one of which is adding webpage functionality. Now, hopefully all these changes are cross-browser compatible, but to make sure, we need testers using as many platforms and browsers as we can get hold of. We currently have the combinations shown below covered, but could do with coverage a) for ones we don't already have, and b) to provide confirmation of existing test results. Firefox 2, Opera 9, Konqueror on Linux Firefox 2, IE 6, IE 7 on Windows XP Firefox 2, Camino 1.5, Safari 3 on Mac OS X If you are willing and able to help with testing (see http://svn.boost.org/trac/boost/wiki/BrowserTestingChart for details of what's involved), please let me know. I will then add you to the list of testers I have and will let you know when updated docs are available and re-testing is required. I'll then collate results (manually at first, but not for long - I'm lazy). So - please get in touch! Stuart Dootson

Boost::Thread 1.34 - Acess Violation at runtime (release-static)
by Mario Figueiredo 05 Jul '07

05 Jul '07

Hello everyone, I get an access violation at runtime after building against the boost::test release static library. The error doesn't occur with the debug static library. -> MinGW 3.4.5 (last updated 2007-03-26) -> Running Windows XP with SP2 Furthermore, Access violation also occurs after building (against the static-debug lib) doc\boost_1_34_0\libs\test\example\unit_test_example_02.cpp Output occurs as expected, but Access Violation is triggered at system error BOOST_CHECK. No output for this error is shown on screen. Can't seem to be able to copy-paste call stack without triggering a top-posting warning. Let me know if you need it and I'll try to format it. Anyone else experienced this two problems?

[wave] some more question...
by Ovanes Markarian 04 Jul '07

04 Jul '07

Hello Hartmut! I have a file delived from some processor manufacturer which I can not change. In the file I have following defines, which wave can't parse: #define UINT_MAX 4294967295U #define ULONG_MAX 1099511627775U First error which happens during parsing of UINT_MAX is: description: error: ill formed integer literal or integer constant too large: 4294967295U I do not understand why I get the first error, since the value 4294967295U is 0xFFFFFFFF which is 32 bits long and should be fine (since it is also marked as unsigned for the preprocessor)... Clearly the ULONG_MAX has a wrong numeric format (should be 1099511627775UL or 1099511627775ul), but unfortunately this file comes from some vendor and is deeply incorporated into the build process, so that it can not easily be changed. What do you think, could be the possible solution in this case? My other question would be: Is there any change to allow the hooking interface to specify, which preprocessor directives should be expanded, an which not. Let me summarize: I need some few macros to be expanded, which are defined in some 2-3 headers and I do not want wave to preprocess everything (huge source dir). Ideally, it would be great to have some functionality, which can notify the preprocessor whether to skip the preprocessing directive or not, e.g. function void found_include_directive(std::string const &filename, bool include_next); (as well as other functions like expanding_function_like_macro) from the default_preprocessing_hooks interface could additionaly return bool value, which would notify the preprocessor whether to include and expand the file/macro or not. May be in this second case I could solve the first problem as well, since I don't really need these defines, they are parsed as part of dependency, which is not required in my case. With Kind Regards, Ovanes Markarian

get all the elements with a certain value with multi_index
by boost＠larroy.com 04 Jul '07

Hello I'm trying to use multi_index with an ordered_non_unique index. My question is how can I perform a search like with "find(key)" and get all the elements that match that key. Since find only returns one element that match, and there can be several in the container. I've tried to iterate "count(key)" times with the iterator returned by find but doesn't seem to work. Is there a way to do this?

Using lambda bind as destruct functor to shared_ptr
by Scott French 04 Jul '07

04 Jul '07

Hello, Should the following code sample work? It is the simplest reproduction case I could come up with: #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> #include <boost/shared_ptr.hpp> #include <stdlib.h> using namespace std; using namespace boost; using namespace boost::lambda; int main(void) { void * myResource = malloc(5); shared_ptr<void> mySharedResource(myResource, bind(free, _1)); } I get a compile error using g++ 4.0.1 on Mac OS X: /Documents/boost_1_34_0/boost/detail/sp_counted_impl.hpp: In member function 'void* boost::detail::sp_counted_impl_pd<P, D>::get_deleter(const std::type_info&) [with P = void*, D = boost::lambda::lambda_functor<boost::lambda:: lambda_functor_base<boost::lambda:: action<2, boost::lambda::function_action<2, void> >, boost::tuples::tuple<void (&)(void*), const boost::lambda::lambda_functor<boost::lambda::placeholder<1> >, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type> > >]': test.cpp:13: instantiated from here /Documents/boost_1_34_0/boost/detail/sp_counted_impl.hpp:150: error: no match for ternary 'operator?:' in '(+ ti)->std::type_info::operator==(((const std::type_info&)((const std::type_info*)(& _ZTIN5boost6lambda14lambda_functorINS0_19lambda_functor_baseINS0_6action ILi2ENS0 _15function_actionILi2EvEEEENS_6tuples5tupleIRFvPvEKNS1_INS0_11placehold erILi1EE EEENS7_9null_typeESG_SG_SG_SG_SG_SG_SG_EEEEEE)))) ? boost::lambda::operator&(const boost::lambda::lambda_functor<T>&) [with Arg = boost::lambda::lambda_functor_base<boost::lambda::action<2, boost::lambda::function_action<2, void> >, boost::tuples::tuple<void (&)(void*), const boost::lambda::lambda_functor<boost::lambda::placeholder<1> >, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type> >]() : 0' Of course, just using "free" instead of bind(free, _1) works, but my real case is more complicated and this appears to be a general conflict between lambda::bind and shared_ptr.

Iteratiing on regex results with pointer-to-member-function
by Alain Leblanc 04 Jul '07

04 Jul '07

Hi, I wrote some code where I want to iterate on the result of a regex matching and call a member function for each match. It goes roughly like this: ====================================================================== class XX { typedef bool (XX::*FuncPtr)(const boost::match_results<std::string::const_iterator>& what); FuncPtr funcPtr; }; bool XX::regex_callback(const boost::match_results<std::string::const_iterator>& what) { return true; } void XX::addDelayedVariables(string expr) { funcPtr = &XX::regex_callback; regex re("([[:alpha::]][[:alnum]]+)(\[[^\\]]+])"); sregex_iterator m1(expr.begin(), expr.end(), re); sregex_iterator m2; match_results<string::const_iterator> results; (*) bool a = (this->*funcPtr)(results); (*) for_each(m1, m2, (this->*funcPtr)); (#) } =========================================================================== When compiling (gcc 4.1 on FC 6) I get an error message at (#) that says: invalid use of non-static member function I added the two lines with a (*) as a sanity check to see that I declared the pointer-to-member-function correctly, and I have no problem compiling those. So my question is: is this a problem with me not understanding how to handle pointer-to-member-functions in C++, or is there something with the boost libraries that I'm missing or is preventing me from performing this operation? I would appreciate any help or opinion. thanks, Alain

Can't compile boost 1.3.3.1 with stlport 4.6.2
by Hongquan 04 Jul '07

04 Jul '07

Hi Buddy: I down the boost 1.3.3.1 and stlport 4.6.2 and then using the command < bjam.exe -sTOOLS=msvc-stlport -sSTLPORT_4.6.2_PATH=D:\SDK\Stlport\STLport-4.6.2 > to build the boost source ,but some error was threw out in compile process just as: E:\boost_1_33_1\boost/date_time/date_formatting.hpp(64) : fatal error C1001: INT ERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information I searched the web and find out some clues at microsoft web site http://support.microsoft.com/kb/226110/en-us and Microsoft has comfirmed that this is a bug of vc6 . But I'm thinking if there is any other way to build the boost with stlport . If anyone knows it,please give me a tip! Thank you very much! Hongquan I-ZQ

Simple regex question
by david v 04 Jul '07

04 Jul '07

Hello, I'm trying to use regex_search to look for regular expressions. regex = (david|divad) stringtosearch = "david" So I'm looking for regex above in the string "david". As you see a very basic example. I'm expecting to find two hits, but I thought I should recover "david" and "david" and not twice the same match "david" ??? Here is a snippet of the code: .... boost::smatch match; start = stringtosearch.begin(); //that would be the start of "david" end = stringtosearch.end(); // that would be the end of "david" old_pos = 0; cout << "Looking for regex:" << regex << " in string " << stringtosearch << endl; while (boost::regex_search(start,end,match,regex)) { old_pos += match.position()+1; std::string t = match[0]; std::cout << "\tFound:" << match[0] << endl; old_pos += match.length(); start = match[0].second; } catch(const std::exception &regex) { std::cerr << "Exception:" << regex.what() << std::endl; exit(-1); } Here is the output: Looking for regex:(david|divad) in string david Found david Looking for regex:(david|divad) in string david Found david As you can see, pattern "david" is found twice ??? I was expecting two different patterns to be found "david" and "divad". By the way how can I recover the total number of matches found ?? thanks, david _________________________________________________________________ MSN Messenger : discutez en direct avec vos amis ! http://www.msn.fr/msger/default.asp

[signal] How to disconnect?
by Boris 04 Jul '07

04 Jul '07

void Hello() { } boost::signal<void ()> sig; sig.connect(&Hello); // OK sig.disconnect(&Hello); // Error Can anyone tell me how I disconnect the callback function Hello? I can see in the documentation that I can call disconnect with a group_type and with a slot_type but not with a slot_function_type. I'm surprised to run into such a problem as from the point of view of a library user it can't get much easier than that? Boris PS: This is with Boost 1.33.1.

[parameter] _type not defined in function signature
by Krishna Roskin 03 Jul '07

03 Jul '07

Hey everyone, I'm trying to use Boost.Parameter to make my 9 parameter BGL function more manageable. My code is very close to the example given in the Parameter docs for depth_first_search: BOOST_PARAMETER_NAME(simplified) BOOST_PARAMETER_NAME(original) BOOST_PARAMETER_NAME(initial_vertex) BOOST_PARAMETER_NAME(final_vertex) BOOST_PARAMETER_FUNCTION( (void), simp, tag, (required (in_out(simplified), *) (original, *) ) (optional (initial_vertex, (typename graph_traits<original_type>::vertex_descriptor), original.initial_vertex) (final_vertex, (typename graph_traits<original_type>::vertex_descriptor), original.final_vertex) ) ) { simplify(simplified, original, target_io_edge_map<simplified_type, original_type>(), accumulate_edge_weight(), initial_vertex, final_vertex); } When compiling this under GCC 4.0.1 I get an "'original_type' has not been declared" error in the function signature. The original_type in the function body is fine. If I change the type of initial_vertex and final_vertex to *, then everything works fine. Any idea why this code (which is almost the same as the example given for depth_first_search) doesn't work? Thanks for any help anyone can give and I hope everyone's having a good summer. -krish I'm using 1.34 and here's what gcc -v says: Using built-in specs.

[BGL] Troubles with floyd_warshall_all_pairs, johnson_all_pairs
by Alex Ivanov 03 Jul '07

03 Jul '07

Hi, guys! I'm stumbled upon a weird problem using SUBJ. functions! Lets suppose that we don't know how much Vertexes we are going to have (for instance Vertexes might be got from file or stdin). So then, in my opinion, is completely impossible to execute SUBJ functions! Let me explain: =============== int xx; //"xx" is runtime-defined vertices size. double* cmat=new(xx*xx); //"cmat" is adjacency matrix actually, it's also defined during runtime. InitCmat(); //here I fill in "cmat" array typedef adjacency_list<listS, vecS, directedS, no_property, property<edge_weight_t, double> > Graph; //This is from some example Graph G(xx); for (int i=0;i<xx;i++) { for (int j=0;j<xx;j++) { if (cmat[i*xx+j]!=0) { add_edge(i,j,cmat[i*xx+j],G); } } } //and now the most interesting part of the code //AFAIK it's impossible to declare array using directive below in runtime: double [xx][xx] D; //Compiler says the same: "C2057: expected constant expression" //even code: double [(const int)xx][(const int)xx] D; //won't work, so the only option left is to make a pointer: double* D = new [xx*xx] ; //but both "floyd_warshall_all_pairs_shortest_paths" and "johnson_all_pairs_shortest_paths" are declared to take a reference, not a pointer, so you'll get multiple compile errors, if you try to compile like below: floyd_warshall_all_pairs_shortest_paths(G, D); //the instruction above will cause multiple compile errors like this: \boost_1_34_0\boost\graph\floyd_warshall_shortest.hpp(115): error C2109: subscript requires array or pointer type P.S. Compiler is MSVC7.1, but I also read that gcc does the same. P.S.S. Sorry for duplication, if this also appears in [devel] list. =============== 1. What can I do to get this code work? 2. If no workaround is available, don't you think that it's a good idea to change the DistanceMatrix type in prototypes to pointers? Thanks in advance! //Alex.

[Boost.Graph] Parameter for the Dijkstra-Algorithm
by Ewgenij Sokolovski 03 Jul '07

03 Jul '07

Hello, I read in the documentation that the parameter weight_map of dijkstra_shortest_paths should be a model of Readable Property Map. http://www.boost.org/libs/graph/doc/dijkstra_shortest_paths.html Readable Property Map interface defines a function get(), which has to be contained in each implementation of the interface. OK so far. But when you look at the example provided with the boost library, you see that a simple STL vector is used as weight map. http://www.boost.org/libs/graph/example/dijkstra-example.cpp And STL vector doesn't provide a get() function at all. So the whole thing shouldn't work at all. So where is the magic explanation?:) Ewgenij -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS.

problems building Boost.Python with cygwin
by Knox, Matt 02 Jul '07

02 Jul '07

Hello all, I am trying to install the Boost.Python library (and then compile C++ python extensions after that) using cygwin and am not having much luck. I know I have the main part of boost working because I was able to compile and run the basic example for testing the boost configuration. Then to install Boost.Python I did the following: $ ./configure -with-libraries=python This generates the following output: Building Boost.Jam with toolset gcc... tools/jam/src/bin.cygwinx86/bjam Detecting Python version... 2.5 Detecting Python root... c:\Python25 Unicode/ICU support for Boost.Regex?... not found. Backing up existing Boost.Build configuration in user-config.jam.2 Generating Boost.Build configuration in user-config.jam... Generating Makefile... I then type "make install", which generates the following output: ./tools/jam/src/bin.cygwinx86/bjam --user-config=user-config.jam --prefix=/usr/local --exec-prefix= /usr/local --libdir=/usr/local/lib --includedir=/usr/local/include --with-python install WARNING: No python installation configured and autoconfiguration failed. See http://www.boost.org/libs/python/doc/building.html for configuration instructions or pass --without-python to suppress this message and silently skip all Boost.Python targets warning: Python location is not configured warning: the Boost.Python library won't be built warning: Unable to construct ./install-unversioned warning: Unable to construct ./install-unversioned warning: Unable to construct ./install-unversioned warning: Unable to construct ./install-unversioned warning: Unable to construct ./install-unversioned warning: Unable to construct ./install-unversioned warning: Unable to construct ./install-unversioned warning: Unable to construct ./install-unversioned ...found 7812 targets... Those warnings look rather problematic. And indeed, when I try to compile the basic example (/boost_1_34_0/libs/python/example/tutorial) by typing "bjam target-os=cygwin toolset=gcc", I get the following errors: Jamroot:17: in modules.load rule python-extension unknown in module Jamfile</cygdrive/p/c_libs/boost_1_34_0/libs/python/example/ tutorial>. /cygdrive/p/c_libs/boost_1_34_0/tools/build/v2/build/project.jam:312: in load-jamfile /cygdrive/p/c_libs/boost_1_34_0/tools/build/v2/build/project.jam:68: in load /cygdrive/p/c_libs/boost_1_34_0/tools/build/v2/build/project.jam:170: in project.find /cygdrive/p/c_libs/boost_1_34_0/tools/build/v2/build-system.jam:237: in load /cygdrive/p/c_libs/boost_1_34_0/libs/python/example/../../../tools/build /v2/kernel/modules.jam:261: in import /cygdrive/p/c_libs/boost_1_34_0/libs/python/example/../../../tools/build /v2/kernel/bootstrap.jam:132 : in boost-build /cygdrive/p/c_libs/boost_1_34_0/libs/python/example/boost-build.jam:7: in module scope Any ideas?

Hello, I have built Boost 1.34 using the msvc toolkit (vc80) and I am now trying to compile a small test app that uses the filesystem library. The test app source is attached to this mail. The compile itself works just fine and linking to the static version of the filesystem lib works fine as well: $ cl -nologo -EHsc -MDd fst.cpp libboost_filesystem-vc80-mt-gd.lib fst.cpp However, linking to the import library of the shared filesystem library produces an error: $ cl -nologo -EHsc -MDd fst.cpp boost_filesystem-vc80-mt-gd.lib fst.cpp fst.obj : error LNK2019: unresolved external symbol "unsigned int boost::filesystem::detail::not_found_error" (?not_found_error@detail@filesystem@boost@@3IA) referenced in function "private: unsigned int __thiscall boost::filesystem::basic_directory_iterator<class boost::filesystem::basic_path<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::filesystem::path_traits> >::m_init(class boost::filesystem::basic_path<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::filesystem::path_traits> const &)" (?m_init@?$basic_directory_iterator@V?$basic_path@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@Upath_traits@filesystem@boost@@@filesystem@boost@@@filesystem@boost@@AAEIABV?$basic_path@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@Upath_traits@filesystem@boost@@@23@@Z) fst.exe : fatal error LNK1120: 1 unresolved externals Is this a setup issue or a problem with filesystem?

[circular_buffer] problem compiling in VC80
by Paul O'Neill 02 Jul '07

02 Jul '07

The following code will not compile in MSVC80. It seems to be caused by an attempt to access a private member which is made public for the unit testing and so may not be caught by the boost unit tests. This was compiled against the Main CVS on 30-Jun-2007. int main(int argc, char* argv[]) { boost::circular_buffer<int> cb(3); return 0; } A look at the m_it that is referenced (error log below) shows that it is private in when BOOST_CB_TEST is not defined. If I define this macro everything works as expected. #if !defined(BOOST_CB_TEST) private: #endif // #if !defined(BOOST_CB_TEST) // Member variables //! The circular buffer where the iterator points to. const Buff* m_buff; //! An internal iterator. pointer m_it; Any ideas?

[iterator_adaptor] typedef problem
by Mark Ruzon 01 Jul '07

01 Jul '07

In the private part of my own iterator adaptor called skip_iterator, I would like to write the following: private: typedef typename skip_iterator::iterator_adaptor_::difference_type difference_type; void advance(difference_type n); difference_type distance_to(const skip_iterator& x) const; because it looks nice. What I get from gcc 3.4.6 is strange: skip_iterator.hpp:22: error: `typedef ptrdiff_t skip_iterator<__gnu_cxx::__normal_iterator<float*, std::vector<float, std::allocator<float> > > >::difference_type' is private /usr/include/c++/boost_1_33_1/boost/iterator/iterator_facade.hpp:868: error: within this context However, if I forgo the typedef and write uglier code: private: void advance(typename skip_iterator::iterator_adaptor_::difference_type n); typename skip_iterator::iterator_adaptor_::difference_type distance_to(const skip_iterator& x) const; then it compiles and works fine. What is the issue with my typedef? Thanks, Mark

Boost verion lookup

Hello. How can I find out which version of Boost is installed on my system? Currently I do it on the simple way of opening the corresponding boost documentation installed with the boost library and looking at the "latest news" entry. But it isn't a really proper way, is it? What is the right way then?:) Ewgenij -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS. Alle Infos und kostenlose Anmeldung: http://www.gmx.net/de/go/freemail

[filesystem][Windows][1.34.0] Paths not getting normalized correctly.
by Jurko Gospodnetić 01 Jul '07

01 Jul '07

Hi. Boost.Filesystem's path::normalize() function does not remove the trailing '\\.' element and my guess is that it should. I'm using Boost 1.34.0 on Windows XP sp2 with MSVC 7.1. Some expected normalization examples: '.' --> '.' '\\' --> '\\' 'aaa\\..' --> '.' 'aaa\\bbb\\..' --> 'aaa' 'aaa' --> 'aaa' Some unexpected normalization examples: '\\.' --> '\\.' (expected '\\' ) 'aaa\\..\\.' --> '.\\.' (expected '.' ) 'aaa\\..\\.\\.' --> '.\\.' (expected '.' ) 'aaa\\..\\.\\.\\.' --> '.\\.' (expected '.' ) 'aaa\\bbb\\..\\.' --> 'aaa\\.' (expected 'aaa') 'aaa\\.' --> 'aaa\\.' (expected 'aaa') Hope this helps... Best regards, Jurko Gospodnetić

[Boost.Graph] Profiling using the graph library
by Ewgenij Sokolovski 30 Jun '07

30 Jun '07

Hello, I use the boost graph library (Version 1.33.1 of Boost) for my programming task. I wanted to profile my program with gprof. I compilated the source code with the -pg option and linked it also with that option. Now I'm examining the output file of gprof. Some functions of boost graph library are not explicitly listed there althogh I use them. These functions are: vertices() add_edge() What I see instead are some complicated functions. I have copied them here from my gprof-Output. But where are vertices() and add_edge()? Or are they meant by these complicated functions.

[Boost.Graph] Visitors - dummy functions
by Ewgenij Sokolovski 30 Jun '07

30 Jun '07

Hello! I want to implement a visitor for the dijkstra_shortest_paths (...) algorithm. The visitor interface requires several methods which should be provided in each visitor object. But I need only one of these functions. So I considered to implement the others as empty functions like: void function(...) { } The problem now is, that as I apparently don't use the parameters, given to the function, inside of its body, the compiler prints out warnings about unused parameters. Is there a possibility to avoid this annoying thing? Except of disabling the warnings of the compiler in general. Regards Ewgenij -- Psssst! Schon vom neuen GMX MultiMessenger gehört?

boost_regex with/without BOOST_REGEX_MATCH_EXTRA on same machine?
by Markus Grabner 30 Jun '07

30 Jun '07

Hi! For an application I'm writing, I need the match_results::captures feature, which requires to recompile boost with BOOST_REGEX_MATCH_EXTRA. I did so and globally installed the modified boost-1.33.1 on my machine. However, several utilities installed on my machine that came with my Linux distribution (openSUSE-10.2) don't work with the modified library (including the yast2 package manager, which made it somewhat challenging to re-install the original version). So I have two questions: *) What is the recommended installation if applications requiring BOOST_REGEX_MATCH_EXTRA must be installed on the same machine together with applications that don't require this extension? *) Are there any chances that future versions of the boost_regex library will remove this compile-time distinction? Are the few extra bytes for the (unused) m_captures member in sub_match really such a big problem?

[Test] Testing generated code.
by Michael Marcin 30 Jun '07

30 Jun '07

I have written type safe wrappers around some math operations that I need to use everywhere and I expect and rely on them being equivalent to the handcoded or macro based approach for performance reasons. I tend to check the resulting assembly by hand every so often and it surprises me from time to time to see that inefficiencies have crept in. If I write a routine in C and a routine using the type safe wrappers that I expect to have equivalent generated assembly is there a way to test that this is indeed the case? Can anyone else think of a better way to make sure that register usage is optimal, proper inlining is occurring, etc? Thanks, Michael Marcin

ASIO: Detecting broken connections
by Andrej van der Zee 29 Jun '07

29 Jun '07

Hi, I was wondering how I can find out with ASIO whether a connection is broken. I have a client connected to the server that continuously streams data. I have to know at the client-side when the server has hung up. I tried to use an async_write and after 5 erroneous tries the running thread for the connection is terminated. Like this: void connection::run_thread() { while (!stopped()) { event_ptr e = fetch_event(); if (!stopped()) { int write_tries = 0; boost::asio::async_write(_socket, boost::asio::buffer(*e, e->length()), boost::bind(&connection::handle_write, this, boost::asio::placeholders::error, e, write_tries)); } } } void connection::handle_write(const boost::system::error_code &err, const event_ptr event, int write_tries) { if (write_tries == max_write_tries) stopped(true); // thread will break out of its main-loop after being notified if (stopped()) return; // no meaning to continue if (err) { // incremenent write_tries and retry async_write boost::asio::async_write(_socket, boost::asio::buffer(*event, event->length()), boost::bind(&connection::handle_write, this, boost::asio::placeholders::error, event, ++write_tries)); } } I think I am misunderstanding something. I thought that after a async_write the registered handler will be invoked. But the handler is NEVER invoked somehow, although data is send from the client to the server. I have the following questions: - Why is the handler never invoked? When is it supposed to be invoked? - What is the best way to find out a connection has been reset by the server? And client?

[bind] using bind for << to ostream

Hello, i want to use bind to create a pair and forward it to an std::ostream, i.e. like: std::for_each(vec.begin(), vec.end(), bind(&write, std::cout, bind(constructor<std::pair<value_t, value_t> >(), _1, _1))); but the compiler says: ios_base.h:781: error: 'ios_base(const ios_base &)' is private boost/boost/lambda/detail/bind_functions.hpp:472: error: within this context boost/boost/lambda/detail/function_adaptors.hpp: In static member function `static void boost::lambda::function_adaptor< void (*)(ostream &, const pair<value_t, value_t> &) >::apply( void (*)(ostream &, const pair<value_t, value_t> &), const ostream &, const pair<value_t, value_t> &)' ... it seem that temporary is created? why? how to avoid it? i've tried the obvious way (at least for me): std::for_each(vec.begin(), vec.end(), (std::cout << bind(constructor<std::pair<value_t, value_t> >(), _1, _1))); but now the output from compiler is kind of 'heavy stuff' and i'm having difficulties to figure out what am i doing wrong. can you help me, please? many thanks for your attention, Mojmir --------8<---- complete source ------ #include <boost/lambda/bind.hpp> #include <boost/lambda/construct.hpp> #include <memory> #include <vector> #include <iostream> using namespace boost::lambda; typedef int value_t; typedef std::vector<value_t> vect_t; typedef std::vector<std::pair<value_t, value_t> > vect2_t; std::ostream & operator<< (std::ostream & os, std::pair<value_t, value_t> const & p) { return os; } void write (std::ostream & os, std::pair<value_t, value_t> const & p) { } int main () { vect_t vec; vect2_t vec2; vec.push_back(1); std::transform(vec.begin(), vec.end(), std::back_inserter(vec2), bind(constructor<std::pair<value_t, value_t> >(), _1, _1)); // ok /* std::for_each(vec.begin(), vec.end(), bind(&write, std::cout, bind(constructor<std::pair<value_t, value_t> >(), _1, _1)) ); std::for_each(vec.begin(), vec.end(), (std::cout << bind(constructor<std::pair<value_t, value_t> >(), _1, _1))); */ } This e-mail and any attachment is for authorised use by the intended recipient(s) only.

Cross-compiling boost for win32 on linux
by rodolfo＠rodsoft.org 29 Jun '07

29 Jun '07

Hi, I used to be able to cross-compile boost on linux for win32 with boost.build v1 without problems, but now with v2 I cannot find the mingw toolset. It seems that now we can use gcc toolset but with a mingw flavor. So, where can I set this flavor? Everything I do makes bjam use plain g++ (for building to run on linux), not mingw32-g++ (run on win32). Regards, Rodolfo Lima.

about shared_ptr
by Daniel Oberhoff 28 Jun '07

28 Jun '07

Hi all, I am using shared_ptr to ease implementation of a matlab file wrapper. Esepcially the fact that it is in tr1 and thus available on many platforms already pushed that decision. Now I was wondering about one thing: Is there a devent way, using shared_ptr, to hand out multiple references? What I mean is something like this: class Variable { shared_ptr<Variable> ref(); }; The problem with shared_ptr is, that, or so it seems, you can only create one directly from the object like this: shared_ptr<Variable> p(new Variable(...)); and all further references have to be created as copies of this (or copies of copies...). So I have to keep one of those around to make new ones. But I cannot keep one inside the class itself or else it will never be deleted (because it would reference itself). The same goes for weak_ptr, since there must be a live shared_ptr around for the object not to be deleted. The only way I can think of is implementing my own refcount and hooking into my own release method. THe problem with this is that I cannot, acoording to the docs, hook up the retain method, so each shared_ptr "cloud" (i.e. set of shared_ptrs that have been created from a common shared_ptr) is hooked up to one ref_count, so they might invalidate when the object stays alive, making any attached weak_ptrs useless. The other is using intrusive_ptr, but that a) is not in tr1 and b) does not have a weak ptr. I was also wondering why intrusive_ptr is not wrapped inside shared_ptr, i.e. why I cannot hook up both retain (increase refcount) and release into shared_ptr, but I suppose that is for the developers list. One other way I could think of would be that I keep a reference to the global ref_count of all the shared_ptrs, and creating new shared_ptrs on top of that, thus binding all shared_ptrs together, but that part does not seem to be exposed in the api. Any Ideas? Daniel Oberhoff ps: should it be possible to post to this list via gmane? I would like that much better, so this won't clog my inbox. But trying to post I keep getting error 441 in gnus

[ snip ] Hello Avery, I suspect You need to BOOST_CLASS_EXPORT(A) as well, since You do try to serialize an A in X's serialize() method. This is was I ended up doing when serializing a hierarchy of derived classes and a base class. I'm not sure how to do that in Your case, since I had all classes and all BOOST_CLASS_EXPORT macros in a single header file. HTH, Johan Franzén

when i clean the solution and then rebuild it,it is useless; >* Try disabling the option /Gm (Enable Minimal Rebuild.) Yes,i just turn off it,then the error disappear. ps: its really a painful thing waiting for compiling, it about 10s for that litte file in a pentium 2.8G cpu. 一起来，150 万人同时在玩的梦幻西游

Creating a property map inside Dijkstra Visitor
by Jonas Gabriel 28 Jun '07

28 Jun '07

Good afternoon, Inside a dijkstra visitor I would like to change the edge weights at some point, so in my visitor I'm trying to make a property map called weight : > template<class DynamicMap> > class gds_visitor : public dijkstra_visitor<> > { > public: > > gds_visitor(DynamicMap input):dynamic(input){} > > .... > > template <class Edge, class Graph> > void examine_edge (Edge e, Graph& g) { > typename property_map<Graph, edge_weight_t>::type weight; > weight=get(edge_weight, g); > > std::cout << "An edge is being examined..." << "\n"; > } > > protected: > DynamicMap dynamic; > }; where Graph: > typedef adjacency_list<listS, vecS, directedS, no_property, property<edge_weight_t, int> > Graph; and Edge: > typedef std::pair<int, int> Edge; But it is not compiling, mentioning a problem with weight 'soperator = . Thank you in advance, Jonas Gabriel
