[Lazarus] OS X/Carbon Compilation

[Hess, Philip J]

Damien,

I google and found this:

See this item down in known issues:

Re-export cycle detection causes many X11 programs to fail to link

There are two libGL.dylib files. One in /usr/X11/lib and one in /System/Library/Frameworks/OpenGL.framework/Libraries and the former re-exports the latter. 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.

#

That looks like the error you're getting.

Maybe you can comment out the OpenGL dependency in the Carbon widgetset for now until this gets worked out.

Thanks.

-Phil

Thanks for the OPT,  I missed -framework just before -kOpenGL.  
However, I still have a(nother) problem :)

In the same time, I think a dependancy on the OpenGL framework is not  
a great idea for an application which does not use it.
