Hello all, I'm trying to cross compile boost python under linux to windows using the mingw32 compiler. Static linking works great, but when trying to make a dll, I get the following errors: gcc.link.dll bin.v2/libs/python/build/gcc-mingw-mingw32/release/target-os-windows/threadapi-win32/threading-multi/libboost_python-mt.dll.a /usr/bin/i686-w64-mingw32-ld: cannot find -lutil /usr/bin/i686-w64-mingw32-ld: cannot find -lpthread /usr/bin/i686-w64-mingw32-ld: cannot find -ldl collect2: ld returned 1 exit status My compile line is: b2 --with-system --with-date_time --with-python --with-filesystem --with-program_options -j 4 toolset=gcc-mingw32 target-os=windows threadapi=win32 variant=release --layout=tagged -sNO_BZIP2=1 -sNO_ZLIB=1 link=shared All the other libraries (system, date_time, program_options) generate dlls sucessfully. Any help is appreciated. Thanks!
