Install Required RHEL/CentOS Packages

Before installing the Vitis software platform on CentOS or RedHat, you must install the Extra Packages for Enterprise Linux (EPEL), and ensure you have the proper kernel-headers and kernel-devel packages installed. The initial setup commands depend on your operating system. For more information, see https://fedoraproject.org/wiki/EPEL.

Install EPEL.
On RedHat:
To enable an additional repository on your system and install the packages, open a terminal window, and enter the following command:
```
$ sudo yum-config-manager --enable rhel-7-server-optional-rpms

$ sudo yum install -y https://dl.fedoraproject.org/pub/epel/
epel-release-latest-7.noarch.rpm
```
On CentOS:
Open a terminal window, and enter the following command:
```
sudo yum install epel-release
```
To install kernel headers and kernel development packages, run the following commands:
```
$ sudo yum install kernel-headers-`uname -r` 
$ sudo yum install kernel-devel-`uname -r`
```
Note: Ensure that uname is surrounded by backticks (`) and not single quotes (').
To install additional packages required for emulation, run the following commands.
```
sudo yum install gcc
sudo yum install gcc-c++
sudo yum install python2
ln -s /usr/bin/python2 /usr/bin/python
```
Cold reboot your system.
