Hi, I build release 1.36.0 on linux using jam successfully. By using this, I've got linker errors: interpreter.cpp.o: In function `void boost::call_once<void (*)()>(boost::once_flag&, void (*)())': interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x16): undefined reference to `boost::detail::get_once_per_thread_epoch()' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x4f): undefined reference to `boost::detail::once_epoch_mutex' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x89): undefined reference to `boost::detail::once_epoch_mutex' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0xc1): undefined reference to `boost::detail::once_global_epoch' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0xc7): undefined reference to `boost::detail::once_global_epoch' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0xd2): undefined reference to `boost::detail::once_global_epoch' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0xd8): undefined reference to `boost::detail::once_global_epoch' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0xdd): undefined reference to `boost::detail::once_global_epoch' CMakeFiles/eda.dir/src/python/interpreter.cpp.o:interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0xe3): more undefined references to `boost::detail::once_global_epoch' follow CMakeFiles/eda.dir/src/python/interpreter.cpp.o: In function `void boost::call_once<void (*)()>(boost::once_flag&, void (*)())': interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0xf2): undefined reference to `boost::detail::once_epoch_cv' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x125): undefined reference to `boost::detail::once_epoch_cv' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x198): undefined reference to `boost::detail::once_epoch_mutex' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x19f): undefined reference to `boost::detail::once_epoch_cv' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x20e): undefined reference to `boost::detail::once_global_epoch' interpreter.cpp:(.text._ZN5boost9call_onceIPFvvEEEvRNS_9once_flagET_[void boost::call_once<void (*)()>(boost::once_flag&, void (*)())]+0x214): undefined reference to `boost::detail::once_global_epoch' main.cpp.o: In function `main': main.cpp:(.text+0x312): undefined reference to `boost::program_options::options_description::m_default_line_length' main.cpp:(.text+0x3aa): undefined reference to `boost::program_options::options_description::m_default_line_length' main.cpp:(.text+0x478): undefined reference to `boost::program_options::options_description::m_default_line_length' main.cpp:(.text+0x4c6): undefined reference to `boost::program_options::options_description::m_default_line_length' main.cpp:(.text+0x55e): undefined reference to `boost::program_options::options_description::m_default_line_length' Any ideas what gone wrong? linker flags where: -rdynamic -L/usr/local/boost_1_36_0/lib ... -lboost_python -lboost_program_options -lboost_thread -Wl,-rpath,/usr/local/boost_1_36_0/lib:/usr/lib/python2.5/config Thanks, Olaf
