Hi, Sorry for my late reply. Anyway I solved the problem in installing the official version of Python and not the activestate version. Thanks a lot for your help. Cheers. Julien. -----Message d'origine----- De : Boost-users [mailto:boost-users-bounces@lists.boost.org] De la part de Steven Watanabe Envoyé : vendredi 1 mars 2013 23:54 À : boost-users@lists.boost.org Objet : Re: [Boost-users] Problem for compiling Boost 1.53 AMDG It looks like the problem is that you're using a native Windows python installation with MinGW. MinGW doesn't understand the import lib, so it tries to link to python2.7 .dll directly. IIRC, This doesn't handle global variables correctly. (Notice that all the undefined references are for variables, not functions.)
