[Lazarus] OS X/Carbon Compilation

[Hess, Philip J]

I was going to suggest that, but it's not clear to me how to do that. In the Inherited tab, it includes /usr/X11R6/lib; /sw/lib even when Carbon is selected. These library paths are read-only and appear to be hardwired into the IDE.

Thanks.

The Mac OS X 10.5 linker uses -L paths to search for indirect libraries. The combination of these two causes a re-export cycle which will make the linker error out. The work around is to add: -dylib_file /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib to the link line. The -dylib_file option takes a colon separate pair of paths and instructs the linker where to look for a particular indirect dylib.

Or remove the X11 dependency, since you're compiling for carbon.
