Could you check the two files in https://gna.org/patch/index.php?2960 ... Which two? And what am I testing them for? Sorry, my answer was too short ;-) The patch basically rewrites the debug.m4 file. It collects all debug relating code of the configure process and puts it in this file. The second patch changes the handling of --enable-debug=yes to include nearly all checks but the check which results in a compile error for gtk2. This check can be activated using --enable-debug=checks. The question is, if this is a configuration as you asked? ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev

Yeah, i need to file some bugs in this area too. Compilation fails
when using clang [which is now default on OSX 10.7/XCode 4.2]:

In the meantime i've set my package to use llvm, but enable-debug is
problematic. A user reported that it fails later with warnings registry.c.
I don't have a specific error message, but will see what i can dig up.
