This is probably https://github.com/cython/cython/commit/c9765a85e1f11a61c604890435b8cebdd49e4cca which means your declaration of callback_test_hello in callbacks.cpp also needs to be extern "c" to have the same (i.e. no) mangling. - Robert _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
