Dear PWSCF Users,

I have set the environment for PWgui in two systems: RedHat8 and RedHat10.
In the former case everything is ok but in the latter I get the following
message:
----------------------
 PWgui: using the system default "wish" interpreter

 PWGUI       : /home/pwscf/.PWSCF_ROOT/PWgui-0.6.1
 GUIB engine : /home/pwscf/.PWSCF_ROOT/PWgui-0.6.1/lib/Guib-0.2.1

./pwgui: line 55: 15360 Segmentation fault      wish $PWGUI/pwgui.tcl
--------------------------------
How can I fix this problem?
Thanks for any comments.
Best regards,

Mahmoud Payami
