Chipscope under Linux

In fact the problem was with Chipscope server, when I tryed to launch it, it gace the following message:

----DEGIN---- cs_server.sh /opt/Xilinx/ISE7.1 application-specific initialization failed: Can't find a usable init.tcl in the following directories: /usr/local/lib/tcl8.4 /opt/Xilinx/chipscope/bin/lib/tcl8.4 /opt/Xilinx/chipscope/lib/tcl8.4 /opt/Xilinx/chipscope/bin/library /opt/Xilinx/chipscope/library /opt/Xilinx/chipscope/tcl8.4.3/library /opt/Xilinx/tcl8.4.3/library /usr/local/lib/tcl8.4

This probably means that Tcl wasn't installed properly.

CS% /opt/Xilinx/chipscope/bin/lin/cs_server.sh: line 26: 4504 Segmentation fault cse $args

----END----

The solution was to copy the tcl8.4 directory (from the $CHIPSCOPE/bin/lin/xilinx/bin/lib/tcl8.4) to /usr/local/lib ... after that all was normal. I don't undestand why I had such an error, even changing the environment variables (LD_LIBRARY_PATH, PATH, XILINX, CHIPSCOPE) didn't change the error messages displayed by the server, this means that the paths are hard coded and don't use environment variables, very strange for me to see this kind of errors from Xilinx.
