Appendix B
Creating a Vault Repository for
CentOS
On CentOS, yum install kernel-headers always installs the latest version of the headers,
but might not match your kernel version. This causes the installaon of XRT to skip compilaon
of the driver modules and will silently fail. To correctly install XRT, you must create a vault
repository le that points to versions matching the kernel.
Use the following example repository as a guide to create your own repository. It is an example
repository for CentOS 7.4 created in the following le:
/etc/yum.repos.d/centos74.repo
# CentOS-Base-7.4.repo
#
# This repo is locked to 7.4.1708 version
#
# C7.4.1708
