[Bug-gnubg] Compile error/3d error on MacOS 10.5.2 (Leopard)

[Achim Mueller]

 Hi again,

threads are working fine, but there is a problem with 3d-support. On the
system there are two directories:

macace:gnubg ace$ ls -l
/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries 
total 54672
-rwxr-xr-x  1 root  wheel    584848 19 Feb 07:00 libGL.dylib
-rwxr-xr-x  1 root  wheel   1325776 19 Feb 07:00 libGLImage.dylib
-rwxr-xr-x  1 root  wheel  24242144 19 Feb 07:00
libGLProgrammability.dylib
-rwxr-xr-x  1 root  wheel   1832592 19 Feb 07:00 libGLU.dylib

lrwxr-xr-x  1 root  wheel       14 31 Mär 22:06
/usr/X11R6/lib/libGLU.dylib -> libGLU.1.dylib

When I just compile with --with-3dboard the linker stops:

ld: cycle in dylib re-exports with /usr/X11/lib/libGL.dylib

This seems to be a known bug, see also
http://my.bzflag.org/bb/viewtopic.php?t=12107#120160.

When I set export
LDFLAGS=${LDFLAGS}-L/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries
 

the sources compile, but after starting gnubg I get this error:

Python supported.
SQLite database supported.
Window system supported.
External players supported.
XML match equity files supported.
3d Boards supported.
External commands supported.
Multiple threads supported.
SSE supported and available.
