I am using Ubuntu 18.04 in the host machine and succesfully initialized the opencl image in the a10gx board.
I am trying to run aocl install with a10_ref bsp but its apparently broken. Below is the error log.
Error log

Is there simple fix for this issue without downgrading my kernel to 16.04? It will be really helpful if someone can come up with a solution with simple tweak

You need to Install the Build essentials first.
sudo apt-get install build-essential
./make_all.sh: 45: ./make_all.sh: make: not found
means it can not find make which is part of the Build System.
after that re run the setup
Greetings Thomas

Thank you for the answer. Now make file can find build system but i get following errors

new linux kernel has some changes and remove some deprecated structs and methods. I had to make changes to the driver source files for a successful compilation.
