Officially the ISE suite is not supported to run on RHEL / CentOS 7. But since time moves on and Vivado nowadays is supported on those systems you may be tempted to run the ISE tools on this system as well.

If you face the issue that XPS just shows a blank window and even XPS project files are opened as text files, the following will probably solve this issue:

yum install mesa-libGLU

By now this was also mentioned on a Xilinx forum thread but I thought I’d post it anyway.
