Dear prof. tone,<BR>in my old posts (<a href="http://www.democritos.it/pipermail/xcrysden/2012-March/001121.html">http://www.democritos.it/pipermail/xcrysden/2012-March/001121.html</a>) i had been observing problems with fermi surface visualization.<BR>as you suggested i compiled the latest version, which downloaded and installed all the required libraries it self. for the time it worked great.<BR> <BR>however, it is again having same problem. when i try to visualize FS, it crashes with the following error:<BR> <BR><font style="font-size: 8pt;" size="1" face="Courier New">*** glibc
