[xcrysden] swrast driver error

[Juanjo Meléndez]

Dear all:

I have installed the shared version of XCrysDen-1.5.60. Everything went on fine, apparently, as I found the executable. It actually starts to run, but then I get the message:

Executing: /home/bloch/xcrysden-1.5.60/bin/ftunit
libGL error: failed to load driver: swrast

I have googled the first error, and found that it might be related to broken symbolic links to libGL libs. In my case, I have:

ls -l /usr/lib64/libGL.*
	/usr/lib64/libGL.so -> libGL.so.1.2.0
	/usr/lib64/libGL.so.1 -> libGL.so.1.2.0
	/usr/lib64/libGL.so.1.2.0

so this does not seem to be the problem. I also checked that /usr/lib64/dri/swrast_dri.so exists. The test “LIBGL_DEBUG=verbose glxgears” yields the same swrast error. 

Do you have any ideas about what could be happening?

Thanks a lot in advance
