Hi all, I failed compiling luabind using boost 1.3.2 on AIX 5.1 (xlC) xlC -c class_rep.cpp -o class_rep.o ... -I.. -I/some_dir/include/boost-1_32 "/some_dir/include/boost-1_32/boost/mpl/aux_/O1_size_impl.hpp", line 33.38: 1540-0827 (S) The constant expression on the #if directive contains a syntax error at "BOOST_TESTED_AT". "/some_dir/include/boost-1_32/boost/mpl/aux_/include_preprocessed.hpp", line 31.13: 1540-0836 (S) The #include file "boost/mpl/aux_/preprocessed/AUX_PREPROCESSED_HEADER" is not found. "/some_dir/include/boost-1_32/boost/mpl/aux_/include_preprocessed.hpp", line 31.13: 1540-0836 (S) The #include file "boost/mpl/aux_/preprocessed/AUX_PREPROCESSED_HEADER" is not found. -- <snipped> -- To me it looks like a configuration problem, but bjam nicely installed the boost-base as specified without any errors. Any help is very appreciated! Christoph
