boost::threads and dual processor Macs
by Stephen Carson 13 Dec '04

13 Dec '04

We are having a problem that we have narrowed down to a problem with boost::threads on dual processor Macs. The very same software works fine, with boost::threads, on a single processor Mac. It also works fine with native Mac threads on a dual processor Mac. The crash is repeatable though, as threaded programs are wont to do, it crashes in slightly different places each time. The program does seem to crash during memory allocation. We have CodeWarrior 9 on its way to see if a compiler upgrade might address the problem, (there are some known problems with CodeWarrior 8 and threads, but only in debug builds. We see our crash in release builds as well). Our questions for the boost crew: -Are there any known issues with boost::threads and multi-processor machines? -Has boost::threads been tested on multi-processor machines? On multi-processor Macs? Details: Compiler: CodeWarrior 8.3 Computer: Dual processor 1.8Ghz Macintosh G5 OS: MacOS X 10.3.6 Boost: v1.31 -- Stephen W.

Hi, Has anyone tried and have succeed in compiling and using boost from the command line using the vc toolkit provided by Microsoft? I have tried to compile boost using bjam but I get messages such as "The system cannot find the path specified." I have take care to define VC71_ROOT variable and included the appropriate \bin, \lib, \include directories. Thanks for the help. K

boost::threads: howto organize them ?
by Martin Pasdzierny 13 Dec '04

13 Dec '04

Hi Boost::Thread users (developers) During the past months I had to create a portable thread management shell around boost::threads to allow a simple thread management. The idea was to (implicitly) put each thread into a hierarchy (just like forked processes but with more features than boost::threadgroup offers). These threads now share a global structure to allow global access to their control interface (mainly a 'stop!' flag). Additionally I wanted to make threads requested to stop (triggered by themselves or from outside) implicitly stop their children and finally remove themselves from the thread management structures. It took me some time to make this approach a stable implementation (would have been much easier if boost::threads exposed their internal and platform-specific id). I think the idea of hierarchially organized threads is quite common and wonder how it could be *elegantly* designed using boost::threads. Any suggestions are welcome ! Martin.

Hello I would like ot use g++ to compile a programme which use boost regex To use regex I put this lines in the header of test_expreg.cpp : #include <boost/cregex.hpp> #include <boost/regex.hpp> The file compiles fine with this command line : g++ -c test_expreg.cpp -o test_expreg.o But I can't link : g++ -o test_expreg test_expreg.o Produce error : : undefined reference to `boost::RegEx::RegEx(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, bool)' I tried : g++ -o test_expreg test_expreg.o -L/usr/bin -llibboost_regex And obtained this error : /usr/bin/ld: ne peut trouver -llibboost_regex Someone could tel me how compile correcly this programme that already compiles well en Microsoft Visual C++ but that I can't compile with g++ on Linux Fecora Core 3 Thanks, Laurent

Problems with compiling Boost 1.32.0 in RHEL 3.0 on Itanium2
by Yuguang Xiong 11 Dec '04

11 Dec '04

First of all, Boost 1.32.0 can be compiled correctly in IA32 platform without any problems. But when I tried to compile it on Itanium2 system, I ran into the following problem: I issued the standard building command: bjam "-sTOOLS=gcc" install which supposes to compile both the debug and the release , both the static and the dynamic, both the single-threading and multi-threading versions, specified by the default value of the BUILD variable: "-sBUILD=debug release <runtime-link>static/dynamic <threading>single/multi" However an error always occurred when the compilation went to this place: gcc-C++-action bin/boost/libs/thread/build/libboost_thread.so/gcc/debug/shared-l inkable-true/threading-multi/barrier.o In file included from /home/xyg/downloads/boost_1_32_0/boost/thread/detail/confi g.hpp:18, from /home/xyg/downloads/boost_1_32_0/libs/thread/src/barrier.c pp:12: /home/xyg/downloads/boost_1_32_0/boost/config/requires_threads.hpp:47:5: #error "Compiler threading support is not turned on. Please set the correct command lin e options for threading: -pthread (Linux), -pthreads (Solaris) or -mthreads (Min gw32)" Since my Itanium2 runs RHEL 3.0 with the standard GCC 3.2.3, the same version of the GCC that I used to compile Boost in RHEL 3.0 on IA32 platform, I don't understand why this error happened. Could anyone tell me how to get Boost 1.32.0 compiled smoothly on Itanium2 machine? Any information are greatly appreciated! Thanks a lot! __________________________________ Do you Yahoo!? Yahoo!

Quick questions
by TEMPLIE Cédric 10 Dec '04

10 Dec '04

Hello, I am new with the build boost sytem, before I wanted to use jam, but it was not enough for me. I have 2 quick questions: - How it is possible to check if a directory is present or not ? - I want to do a system call before building some files, how can i do that (I want to call perforce to sync the files before compiling them....) ? Thanks in advance for your answers. TEMPLIE Cédric

Serialization: Cannot use name-value-pairs with indirectly serialized maps.
by Martin Proulx 10 Dec '04

10 Dec '04

Hello, While evaluating the serialization library, I've ran into a problem while modifying my code to add name value pairs to the serialized objects in order to be able to serialize them to an xml file. before doing this, everything worked fine, but now that I'm using NVPs, I get the following error: c:\projects\dev_tools\libs\c++\boost_1_32_0\boost\serialization\access.hpp(106): error C2039: 'serialize' : is not a member of 'std::map<_Kty,_Ty>' with [ _Kty=std::string, _Ty=std::string ] I'm using VC 7.1, and a stripped-down but compilable version of the code that causes the problem is included at the end of this mail. I'm really puzzled at this problem as the following modifications to the code will have things compile: -) Comment out only the 'oa << BOOST_SERIALIZATION_NVP(instanceOfB);' line. -) Comment out only the 'ia >> BOOST_SERIALIZATION_NVP(instanceOfB);' line. -) Serializing and unserializing directly the instanceOfA object instead. -) redefining BOOST_SERIALIZATION_NVP to 'BOOST_SERIALIZATION_NVP(x) x' is this really a bug or am I missing something ?

Some suggest to the author of Serialization Lib
by goodmen 10 Dec '04

10 Dec '04

Dear Robert Ramey , Here is a new boost user ( but an 'old' c++ programmer ) writting to you. Now , with several painful night , my test code of serialization lib has't run. OK , as some letter in the list , I meet the link problem. The libs has been compiled and linked with bjam correctly,and the lib files have been copied to the right position.But the compiler complained there are some symbol not resolved. I have inspected the source code,and find the serialization use some file in the [[archive]] dir. And in the docs, there are no any info about archive. It seems that archive is not an independent lib(bjam not compile the archive files,but copy the header file to the destination dir). Some classes in the archive are used by Serialization, but the implementation of these classes are not processed by bjam,so these class excite link errors(not compile errors!). Another feedback about your code is that There are not any C1204 compile error in MSVC71 if you build in the release mode. It seems that in debug mode, the compiler add addition info to the result binary and madee the scope of compiling became to too large to the compiler. Here are some questions about the serialization: 1, Is the archive written by you ? 2, Is the archive an independent lib? 3, how can I solve the link problem? 4, It seems that there is not a single header file that can be included by user who want to use the serialization(and the user can forget all other header files ). Do you have any plan to add this feature ? Here are my suggestions: 1, Take the archive to be an independent lib. 2, Move the whole serialization code to the head file,so there is no need to compile the lib with the bjam,and this can bring more protablity.( Since the io stream interface of stl is standard, I think it is no need to compile code into platform specific libs ) note: I am a Chinese , and my english is poor . If some word above offends you or seems to be impolite , forgive me please ^_^ 　　　　　　　　goodmen 　　　　　　　　goodmen(a)x263.net 　　　　　　　　　　2004-12-09

OK, here is the code: #include<boost/numeric/ublas/storage.hpp> #include<boost/numeric/ublas/lu.hpp> using namespace boost::numeric::ublas; int main(){ // create a permutation matrix permutation_matrix P( 5 ); // default contructions gives the identity-permutation return 0; } The errors are: g++ -c -I. -I/s/chopin/a/grad/dane/thesis/code/boost-1.32/include/boost-1_32 -Wall -g3 -o permutationTest.o permutationTest.cpp In file included from permutationTest.cpp:5: /s/chopin/a/grad/dane/thesis/code/boost-1.32/include/boost-1_32/boost/numeric/ublas/lu.hpp: In function `typename M::size_type boost::numeric::ublas::axpy_lu_factorize(M&, PM&)': /s/chopin/a/grad/dane/thesis/code/boost-1.32/include/boost-1_32/boost/numeric/ublas/lu.hpp:181: error: parse error before `>' token /s/chopin/a/grad/dane/thesis/code/boost-1.32/include/boost-1_32/boost/numeric/ublas/lu.hpp:181: error: parse error before `)' token permutationTest.cpp: In function `int main()': permutationTest.cpp:15: error: `permutation_matrix' undeclared (first use this function) permutationTest.cpp:15: error: (Each undeclared identifier is reported only once for each function it appears in.) permutationTest.cpp:15: error: parse error before `(' token I thought that this error might signal the need for including vector.hpp (or vector_expression.hpp or something) but this did not fix it. Including operation.hpp (which I beleive contains the definition for axpy) causes several screen-fulls of errors! Again, I am at a loss and appreciate any help I might receive. Thank you, Dan elliott

Linker error when building regex (Boost 1.32.0) with Visual C++ 7.1
by Jochen Hammann 10 Dec '04

Hello, I tried to build the regex library from Boost 1.32.0 with the Microsoft Visual C++ 7.1 compiler and without native wchar_t support. Below is the call to bjam: bjam -sTOOLS=vc-7_1 "-sBUILD=<native-wchar_t>off" --with-regex The build results of the dynamic link library (DLL) shows the following linker errors: Creating library bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debug\native-wchar_t-off\threading-multi\boost_regex-vc71-mt-gd-1_32.lib and object bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debug\native-wchar_t-off\threading-multi\boost_regex-vc71-mt-gd-1_32.exp instances.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) winstances.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) regex.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) regex_debug.obj : error LNK2019: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) referenced in function "void __cdecl regex_lib_print_compiler_macros(void)" (?regex_lib_print_compiler_macros@@YAXXZ) w32_regex_traits.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) wide_posix_api.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) c_regex_traits.obj : error LNK2019: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) referenced in function "public: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::syntax_type(unsigned int)const " (?syntax_type@?$cpp_regex_traits@_W@boost@@QBAII@Z) c_regex_traits_common.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) cregex.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) posix_api.obj : error LNK2001: unresolved external symbol "private: unsigned int __cdecl boost::cpp_regex_traits<wchar_t>::do_syntax_type(unsigned int)const " (?do_syntax_type@?$cpp_regex_traits@_W@boost@@ABAII@Z) bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debug\native-wchar_t-off\threading-multi\boost_regex-vc71-mt-gd-1_32.dll : fatal error LNK1120: 1 unresolved externals ...failed vc-Link bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debug\native-wchar_t-off\threading-multi\boost_regex-vc71-mt-gd-1_32.dll bin\boost\libs\regex\build\boost_regex.dll\vc-7_1\debug\native-wchar_t-off\threading-multi\boost_regex-vc71-mt-gd-1_32.lib... ..skipped <@boost!lib>boost_regex-vc71-mt-gd-1_32.dll for lack of <@boost!libs!regex!build\boost_regex.dll\vc-7_1\debug\native-wchar_t-off\threading-multi>boost_regex-vc71-mt-gd-1_32.dll... ...skipped <@boost!lib>boost_regex-vc71-mt-gd-1_32.lib for lack of <@boost!libs!regex!build\boost_regex.dll\vc-7_1\debug\native-wchar_t-off\threading-multi>boost_regex-vc71-mt-gd-1_32.lib... The build of the static library succeeds. Do I have to define a special macro, if I want to build regex without native wchar_t support? Or do the regex library support both, native wchar_t support and the mapping to unsigned short? In the header regex_traits.hpp I saw some wrappers to "redirects calls to cpp_regex_traits<unsigned short> to cpp_regex_traits<__wchar_t>". Regards, Jochen.
