Hi all, there is long standing problem with SWIG when you are wrapping around C code and use system headers. SWIG doesn't define "standard" C preprocessor macros. Due this it might happen that wrapped code uses wrong data types, wrong function prototypes etc. There is bug about this problem in upsteam bugzilla (http://sourceforge.net/tracker/?func=detail&atid=101645&aid=1604332&group_id=1645) but upsteam is not going to fix it. List of packages whose use SWIG and their maintainers is on http://atkac.fedorapeople.org/packages_needs_swig. I think every maintainer should check his package and if it uses system C headers he should add this to .i file (SWIG template) $ cpp -dM /dev/null | grep -v __STDC__ > cpp_macros.h # SWIG defines __STDC__ macro and then add '%include "cpp_macros.h" to top of .i file After that you can be sure that wrapped code uses correct data sizes. Feel free to ask me if you have any question.
