Hi, since 1.44 boost python does not compile anymore using python 3.x (after a GSOC project it worked fine with python 3.1). I reported this after the 1.44 release and i thought someone had fixed it. This is really sad to see this great library not working anymore. These are the errors generated: compile-c-c++ e:\devel\_ext\boost_out_64\out\boost\bin.v2\libs\python\build\msvc-10.0\debug\address-model-64\threading-multi\object\function_doc_signature.obj function_doc_signature.cpp E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C2039: 'PyInt_FromLong' : is not a member of '`global namespace'' E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C3861: 'PyInt_FromLong': identifier not found E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C2065: 'PyInt_Type' : undeclared identifier E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C2039: 'PyInt_FromLong' : is not a member of '`global namespace'' E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C3861: 'PyInt_FromLong': identifier not found E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C2065: 'PyInt_Type' : undeclared identifier E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C2039: 'PyInt_FromLong' : is not a member of '`global namespace'' E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(138) : error C3861: 'PyInt_FromLong': identifier not found E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C2039: 'PyInt_FromLong' : is not a member of '`global namespace'' E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C3861: 'PyInt_FromLong': identifier not found E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C2065: 'PyInt_Type' : undeclared identifier E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C2039: 'PyInt_FromLong' : is not a member of '`global namespace'' E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C3861: 'PyInt_FromLong': identifier not found E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C2065: 'PyInt_Type' : undeclared identifier E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C2039: 'PyInt_FromLong' : is not a member of '`global namespace'' E:\devel\boost_1_45_0\boost/python/converter/builtin_converters.hpp(144) : error C3861: 'PyInt_FromLong': identifier not found E:\devel\boost_1_45_0\boost/python/detail/caller.hpp(55) : warning C4244: 'return' : conversion from 'Py_ssize_t' to 'unsigned int', possible loss of data libs\python\src\object\function_doc_signature.cpp(287) : warning C4244: 'initializing' : conversion from 'boost::python::ssize_t' to 'int', possible loss of data libs\python\src\object\function_doc_signature.cpp(294) : warning C4244: '=' : conversion from 'boost::python::ssize_t' to 'int', possible loss of data libs\python\src\object\function_doc_signature.cpp(303) : warning C4244: '=' : conversion from 'boost::python::ssize_t' to 'int', possible loss of data
