Hi, I'm building boost_1_33_1 on mingw win32 environment via: boost-jam-3.1.3-1-ntx86/bjam.exe -sTOOLS=mingw stage Everything goes fine and most libraries are built and run without problems, except for link-time errors of "undefined references" for the following functions: "boost::filesystem::detail::system_error_code()" "boost::filesystem::filesystem_error::~filesystem_error()" "boost::filesystem::filesystem_error::filesystem_error(...)" "vtable for boost::filesystem::filesystem_error" "boost::archive::ARCHIVE_VERSION()" "boost::archive::ARCHIVE_SIGNATURE()" "boost::signals::trackable::signal_connected(...)" It seems some of the object files doesn't get picked up while building their corresponding libraries; for example, ARCHIVE_VERSION() and ARCHIVE_SIGNATURE() are defined in libs/serialization/src/basic_archive.cpp file, which are compiled correctly into basic_archive.obj, yet somehow the bjam link process cannot find it while building the Serialization library. If I inline the definition of ARCHIVE_VERSION() and ARCHIVE_SIGNATURE() into its declaration header file of boost/archive/basic_archive.hpp, the the Serialization library is built without problem. This shows that I'm probably missing something for the above build command. Also, in my mingw win32 build output of stage/lib directory, the corresponding libraries with the above "undefined references" (libboost_filesystem-mgw-*, libboost_serialization-mgt-*, and libboost_signals-mgw-*) are generated as a result of the above bjam build command, even though mingw's ld.exe doesn't recognize these lib files. Is this a bug in bjam logic? Here's my mingw win32 environment: * MSYS-1.0.11-2004.04.30-1 * msysDTK-1.0.1 * binutils-2.16.91-20060119-1 * gcc-core-3.4.5-20060117-1 * gcc-g++-3.4.5-20060117-1 * w32api-3.7 * mingw-runtime-3.10 * mingw-utils-0.3 Attached is the excerpt of above undefined reference errors. I'm not familiar with bjam; it'd be great if someone can shed lights on what's wrong.
