The compiler is compiled by myself. The official mingw website only release the gcc 3.44. I use this complier to compile the boost 1.33.0 and find there is some internal compiler error when compiling python. Since I am not a expert of gcc. I report this and hope it is helpful. I give the all internal compiler error as below C:/opt/boost/boost/python/detail/wrapper_base.hpp:17: warning: type attributes are honored only at type definition C:/opt/boost/boost/python/object/instance.hpp:14: warning: type attributes are honored only at type definition C:\opt\boost\libs\python\build\../src/object/class.cpp:688: internal compiler error: output_operand: invalid expression as operand Please submit a full bug report, with preprocessed source if appropriate.
