libva and libva-drm

[rubikstriangle]

After building OpenRV on centos7 and testing that build in Rocky Linux and Ubuntu I found that I was missing libva and libva-drm. Copying these libs from centos7 into my rv lib folder seems to fix the issue. As a more permanent solution I'm wondering if it would make sense to include these libs in OpenRv by default?

Actually, I tested this out about a week ago and I thought that I had found that libva and libva-drm weren't available on Rocky. I just double checked and found the they are available, they are just one version higher, so libva.so.2 instead of libva.so.1. In this case is it better to create a symbolic link from /usr/lib64/libva.so.2 to /some/dir/rv/lib/libva.so.1 or is it better to use the libs from centos 7. Both seem to work but I haven't thoroughly tested them.

...or would it be better to just compile OpenRV on Rocky Linux 8.7

Compiling on the same Linux distribution as the targeted one is always easier. Otherwise, you need to know what to include and avoid, and it's a trial-and-error process.

What version of Rocky Linux are you using?

Rocky Linux 8.7

You need to have openCL libraries installed. If you have the Nvidia graphics drivers installed it should take care of this. I recently did a build on a virtual machine without a graphics card and found that force installing the Nvidia drivers did the trick.
I also needed to install ninja-devel and meson using yum. Seems like Ninja also comes with QT but it didn't seem to work out of the box for me but the ninja-devel seemed to make the build happy.

I also found that the libva-drm and libra libs are missing on other flavors of linux so I packed it up with my install. This makes Rocky Linux happy.

cp /lib64/libva-drm.so.1.4000.0 /openRV/lib/libva-drm.so.1
cp /lib64/libva.so.1.4000.0 /openRV/lib/libva.so.1

Thanks a lot, it worked
