NixGLHost

Running OpenGL Nix-built binaries on a foreign Linux distro is quite often a challenge. NixGLHost is gluing your nix-built binaries to the host OpenGL implementation.

NixGLHost Approach

TODO before release, rephrase this, explain further. Clone the blog post in this section?

  1. Patched libGLVnd to load vendor DSOs from a custom location, not relying on the library path.
  2. Copy the host vendor DSOs to a nix-tmp location.
  3. Modify the vendor DSOs runpath to point to the place where the vendor libs live.
  4. Wrap the nix-built binary, inject the libGLVnd-specific env variables to point to the patched vendor lib dir.

Support

  • Proprietary Nvidia
    • GLX
    • EGL
    • Cuda
    • OpenCL
  • Mesa
    • GLX
    • EGL
    • OpenCL

Alternative Approaches

  • NixGL: tries to auto detect the host vendor driver, download it again, store it in the nix-store then wraps the nix-built binary and inject the downloaded vendor driver through LD_LIBRARY_PATH.
