could you run yade inside gdb? Like this: $ gdb /usr/bin/python (gdb) run /usr/local/bin/yade-something
(gdb) run ~/YADE/bin/yade-trunk Starting program: /usr/bin/python ~/YADE/bin/yade-trunk [Thread debugging using libthread_db enabled] Welcome to Yade bzr2341 Program received signal SIGSEGV, Segmentation fault. 0x00007ffff39266fc in ?? () from /usr/lib64/libqt-mt.so.3 (gdb) May be the error not connected with QGLViewer library? -- Best regards, Sergei D. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
