[QE-developers] pwgui problem in qe 7.0 on Centos 7

[フォンスポール Ｊ]

Thanks for the research Tone,

Your explanation makes sense regarding Tcl8.6.  I am a little hesitant to upgrade to Centos 8 due to end of life considerations. The server rack I have has infiniband and graphics cards in it and there is a vendor that supports it and changing OS would probably create more problems than it is worth. On the other hand, the binary Paolo mentioned works fine. I think this will be a stop gap solution. Eventually the vendor will supply an OS upgrade to something else they decide to support. For the most part, Centos 7 is very stable and can run for long periods of time without problem. Thanks again.
