FGA tool crashing at startup on centos7

Hi there,

I downloaded and installed intel advisor, in order to use the FGA tool. The advisor gui works fine but if I try to start fga tool I get the following crash:

#0 0x00007f795e4eefc8 in QXcbCursor::queryPointer(QXcbConnection*, QXcbVirtualDesktop**, QPoint*, int*) ()

Looks like a QT5 issue. My system is centos 7.5 64 bit Linux.

Is this a bug in fga? Is there a workaround?

Thanks!

Hi Andres,

Thank you for your submission - we will try to reproduce it and see if there's a workaround.

Andres,

FGA is normally packaged with an appropriate version of Qt.

Looking at the logs, it looks like FGA is picking Qt from some other location.(/lib64/libQt5XcbQpa.so.5)

Starting FGA with the run_fga.sh script ensures that the packaged Qt is picked up rather than any that might be on the system.

Please refer to the link below for directions to start FGA with the run_fga.sh script.

Do not hesitate to let us know if you have any further issues.

Thanks,

Elvis.
