seems it doesn't link libstdc++ :<..\..\mingwlibs\lib\libboost_program_options-mt.a(value_semantic.o):value_semantic.cpp:(.eh_frame+0x12): undefined reference to `__gxx_personality_v0' ..\..\mingwlibs\lib\libboost_program_options-mt.a(convert.o):convert.cpp:(.text+0x2e): undefined reference to `std::codecvt<wchar_t, char, int>::codecvt(unsigned int)'

..\..\mingwlibs\lib\libboost_program_options-mt.a(cmdline.o):cmdline.cpp:(.text+0xf5): undefined reference to `_Unwind_Resume'
anyone knows how to solve this?
