Hi, I need to compile boost python from my linux system. the host system is a 64bits , and the target a 32 bit one. when I try using it on the target system, I have this message, ImportError: ./libboost_python.so.1.55.0: undefined symbol: Py_InitModule4_64 So, I suppose it is not compiled for 32bits system . I have tried many things, what is the right way to compile a 32 bits boost python lib, from a linux 64 bits system ? Regards, Steph
