Free Pascal, OpenCL and NVIDIA WORKS!
lazarus / 64-FPC development

Hi,
I'm able to compile and run OpenCL + NVIDIA + Ubuntu 18.04 under
Lazarus.

This is what I did:
apt-get install nvidia-384 nvidia-opencl-icd-384 clinfo

After installing, reboot your machine.

I tried first to download drivers from nvidia website but my VM
crashed hard when installing these drivers and I had to trash the VM.
Therefore, I think that it's easier to just install plain ubuntu
packages above.

Then, I did a hack:
cd /usr/lib/x86_64-linux-gnu
ln -s libOpenCL.so.1.0.0 libOpenCL.so

Question: is there a better alternative than the hack (ln -s) above?

I'm not certain but usually you would need to install a loader
component like it sounds like the "ocl-icd-opencl-dev" package is.
That will at least create an entry with that name, that I guess will
load the appropriate libOpenCL.so*** file

@Laksen
Just tested installing "sudo apt-get install ocl-icd-opencl-dev" and
it works without having to do the hack "ln -s libOpenCL.so.1.0.0
libOpenCL.so". Tested on Ubuntu 18.04 with NVIDIA GT 730.

Thank you!
