AOCL install failing to find kernel source files

Hello

I am trying to install the aocl drivers on my machine but I am getting the following error: 

# aocl install .
aocl install: Running install from /opt/intel/intelFPGA_pro/17.0/hld/board/a10_ref/linux64/libexec
Looking for kernel source files in /lib/modules/3.10.0-693.11.6.el7.x86_64/build
Looking for kernel source files in /usr/src/kernels/3.10.0-693.11.6.el7.x86_64
Error: Failed to find kernel source files.  The PCIe driver requires
headers and Makefiles for your current Linux kernel, but these could
not be found on your system.  Please install these on the machine.
   For example:
      On RedHat: sudo apt-get source linux
      On Ubuntu: sudo yum install kernel-devel
aocl install: failed.

The machine is running Centos 7.4 and the FPGA is an Arria 10. I tried to install kernel-devel like the warning message suggests but it didn't help. Any recommendations?

Thanks!

Adel

    By default CentOS will install kernel headers for the latest available kernel, which might be newer than your active kernel. Apart from installing kernel headers, you should also update your existing kernel and reboot your machine and after that make sure your kernel and kernel header versions match.
