03 Jul '07

Hi, using Code Blocks i got the folowing message.ld.exe "Cannot find -lboost_filesystem-mgw-mt-s-l_33_l"So I decided to use bjam. Then, cd /jam source location/build.bat. Then I set the variables BOOST_ROOT= C:\Documents and Settings\src\boostand BOOST_BUILD_PATH=C:\Documents and Settings\src\boost\tools\build\v2. So what must I do now in order to build my project with bjam under Code Blocks? Be very clear, Thank You. Thank You _________________________________________________________________ Besoin d'un e-mail ?

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?

[filesystem] Link issues with vc80
by Daniel Andersson 02 Jul '07

02 Jul '07

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? Thanks, Paul. 1>c:\sdk\boost\boost cvs\boost\boost\circular_buffer\debug.hpp(133) : error C2248: 'boost::cb_details::iterator<Buff,Traits>::m_it' : cannot access private member declared in class 'boost::cb_details::iterator<Buff,Traits>' 1> with 1> [ 1> Buff=boost::circular_buffer<int>, 1> Traits=boost::cb_details::nonconst_traits<std::allocator<int>> 1> ] 1> c:\sdk\boost\boost cvs\boost\boost\circular_buffer\details.hpp(231) : see declaration of 'boost::cb_details::iterator<Buff,Traits>::m_it' 1> with 1> [ 1> Buff=boost::circular_buffer<int>, 1> Traits=boost::cb_details::nonconst_traits<std::allocator<int>> 1> ] 1> c:\sdk\boost\boost cvs\boost\boost\circular_buffer\base.hpp(1950) : see reference to function template instantiation 'void boost::cb_details::debug_iterator_registry::invalidate_iterators<boost::cb_details::iterator<Buff,Traits>>(const Iterator &)' being compiled 1> with 1> [ 1> Buff=boost::circular_buffer<int>, 1> Traits=boost::cb_details::nonconst_traits<std::allocator<int>>, 1> Iterator=boost::cb_details::iterator<boost::circular_buffer<int>,boost::cb_details::nonconst_traits<std::allocator<int>>> 1> ] 1> c:\sdk\boost\boost cvs\boost\boost\circular_buffer\base.hpp(1947) : while compiling class template member function 'void boost::circular_buffer<T>::destroy_item(int *)' 1> with 1> [ 1> T=int 1> ] 1> i:\development\projects\test\test\main2.cpp(6) : see reference to class template instantiation 'boost::circular_buffer<T>' being compiled 1> with 1> [ 1> T=int 1> ] -- View this message in context: http://www.nabble.com/-circular_buffer--problem-compiling-in-VC80-tf4010271… Sent from the Boost - Users mailing list archive at Nabble.com.

[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
