This means that OpenGl must be linked-in (not sure if the change from previous Lazarus revisions is intentional).
Building Lazarus on Mac OS X 10.5.2 (i386) with:
make LCL_PLATFORM=carbon OPT="-k-framework -kCarbon -k-framework -kOpenGL"
results in
ld: cycle in dylib re-exports with /usr/X11R6/lib//libGL.dylib An error occurred while linking
The cause is a new feature (AKA bug) in /usr/bin/ld on Mac OS X 10.5, coupled with the fact that Apple rather stupidly chose the same name "libGL.dylib" for two linked but different libraries in /usr/X11/lib and in the OpenGL framework
(<http://lists.apple.com/archives/x11-users/2007/Oct/msg00146.html>)
The fix is to build Lazarus for Carbon with
(<http://wiki.finkproject.org/index.php/Fink:Packaging:Preparing_for_10.5#OpenGL_Bug>)
make LCL_PLATFORM=carbon OPT="-k-framework -kCarbon -k-framework -kOpenGL -k-dylib_file -k/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib"
The build now succeeds
