NixGLHost
Running OpenGL/Cuda/OpenCL Nix-built binaries on a foreign Linux distro is quite often a challenge. These programs are relying on some host-specific graphics drivers at runtime. These drivers are host-specific, it is obviously impossible to distribute the drivers for each and every hosts setup through a pre-defined generic nix closure.
NixGLHost solves this issue by re-using your host system graphics drivers. It copies them to an isolated environment and inject the said environment to the Nix runtime closure.
Current status: experimental.
How to Use
All you have to do is to wrap your nix-built OpenGL/Cuda program with nixglhost
:
For instance, let's say you want to run my-gl-program
, a nix-built
program on your favorite distribution. All you'll have to do is:
nixglhost my-gl-program
Example
Let's nix-build glxgears, living in the glxinfo Nixpkgs derivation then execute it with nixglhost.
cd $thisRepoCheckout
PATH=$(nix build --print-out-paths)/bin:$PATH
nixglhost $(nix build --print-out-paths .#glxinfo)/bin/glxgears

You can read the INTERNALS.md file to learn how exactly NixGLHost
works.
