With the boost CVS from 2005/12/28 I was still able do link boost_python.lib under Windows (using our own build system), but with the latest boost CVS this is no longer possible: link /nologo /incremental:no /dll /out:lib\boost_python.dll /implib:lib\boost_python.lib /LIBPATH:C:\Python24\libs python24.lib boost\libs\python\src\numeric.obj boost\libs\python\src\list.obj boost\libs\python\src\long.obj boost\libs\python\src\dict.obj boost\libs\python\src\tuple.obj boost\libs\python\src\str.obj boost\libs\python\src\slice.obj boost\libs\python\src\aix_init_module.obj boost\libs\python\src\converter\from_python.obj boost\libs\python\src\converter\registry.obj boost\libs\python\src\converter\type_id.obj boost\libs\python\src\object\enum.obj boost\libs\python\src\object\class.obj boost\libs\python\src\object\function.obj boost\libs\python\src\object\inheritance.obj boost\libs\python\src\object\life_support.obj boost\libs\python\src\object\pickle_support.obj boost\libs\python\src\errors.obj boost\libs\python\src\module.obj boost\libs\python\src\converter\builtin_converters.obj boost\libs\python\src\converter\arg_to_python_base.obj boost\libs\python\src\object\iterator.obj boost\libs\python\src\object\stl_iterator.obj boost\libs\python\src\object_protocol.obj boost\libs\python\src\object_operators.obj boost\libs\python\src\wrapper.obj boost\libs\python\src\exec.obj boost\libs\python\src\import.obj LINK : fatal error LNK1104: cannot open file 'libboost_serialization-vc80-mt-1_34.lib' Where does the boost_serialization dependency come from and how can I turn it off?
