Description of problem: The BLT TCL/TK modules massively crash in TK thus the running wish is inflicted and terminates with sig-11/ core dump. Run the demos in the 'demos' directory in the of the package (Fedora-22&23): /usr/share/tcl8.6/blt2.4/demos ) to reproduce. This happens on FEdora-22&23 and on CentOS-7 all the same way. Most demos crash on termination. The 'hierbox' module crashes on startup. Anyway, in this state BLT cannot be used reliably. Best regards.

I have been digging a bit deeper ... You can forget about this. See: http://wiki.tcl.tk/199 This says _clearly_ that BLT in version 2.4 it not compatible; neither with TCL/TK 8.5 (in Fedora-22) nor in TCL/TK-8.6 (in Fedora-23). So, on CentOS-7 it _cannot_ work as well: [root@clumas ~]# cat /etc/centos-release CentOS Linux release 7.2.1511 (Core) [root@clumas ~]# rpm -qa| grep -i tcl-8 tcl-8.5.13-8.el7.x86_64 BLT should be removed from distributions that have TCL/TK >=8.5 installed. It just produces crashes and core dumps. See the above TCL/TK wiki page for replacements. Best regards ...
