[Mesa3d-users] Linking

[Filipe B. <bo...@im...>]

Hi,

I have just installed Mesa 3.1-2 on my Linux Redhat 6.1 and I can't
compile any of my old OpenGL programs. (I used OpenGL on Sun computers,
and I have never used Mesa under Linux.) The problen is in the linking
stage, actually. I installed the RPM file, didn't compile the library
myself, so maybe I didn't do something crucial.

The directory /usr/X11R6/lib contains, apart the non-GL stuff, the
libraries/files

libGL.la	libGL.so.1	libGL.so.1.0	libGL.so.1.2.0
libGLU.la	libGLU.so.1	libGLU.so.1.2.0	libGLU.so.3
libGLU.so.3.1.2	libglut.la	libglut.so.3	libglut.so.3.7
libglut.so.3.7.0

Although I include -L/usr/X11R6/lib in my compile-line I get the
message:

/usr/bin/ld: cannot open -lGL: No such file or directory
collect2: ld returned 1 exit status
make: *** [visu_3D] Error 1

So ld doesn't find the libGL file. I suspect it's because it looks for
an archive file (presumably libGL.a) which doesn't exist.

Reading the README files from the Mesa WWW page, I tried (as root) to
run "ldconfig -v" but that didn't solve it. I restarted Linux with no
more success.

Can anyone tell me how I can compile my programs? Do I have to create
the archive with ar? Is there some compile-lne option I forgot?

Thanks,

Fil
