Issue Potential Cause Fix
XRT package fails to install in
CentOS7.4 or CentOS7.5
Kernel development headers are
missing. The XRT package is missing a
dependency on kernel-devel and
kernel-headers.
Manually install kernel-devel and
kernel-header with yum install:
$ sudo yum install kernel-
headers-`uname -r`
$ sudo yum install kernel-
devel-`uname -r`
Note: Do not run sudo yum upgrade.
This will update the kernel-headers to an
incompable version.
