Dear all:
<div class=""><br class="">
</div>
<div class="">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

<div class="">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:</div>
<div class=""><br class="">
</div>
<div class="">ls -l /usr/lib64/libGL.*</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>/usr/lib64/libGL.so
-> libGL.so.1.2.0</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>/usr/lib64/libGL.so.1
-> libGL.so.1.2.0</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>/usr/lib64/libGL.so.1.2.0</div>
<div class=""><br class="">
</div>
<div class="">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. </div>
<div class=""><br class="">
</div>
<div class="">Do you have any ideas about what could be happening?</div>
<div class=""><br class="">
</div>
<div class="">Thanks a lot in advance</div>
