This tool tries to solve the "OpenGL" problem on nix.

Motivation

You use Nix on any distribution, and any GL application installed fails with this error:

$ program
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

This library contains a wrapper which is able to launch GL application:

nixGL program

Installation / Usage

Clone this git repository:

git clone https://github.com/guibou/nixGL

(Optional) installation:

cd nixGL
nix-build
nix-env -i ./result

Usage:

nixGL program args

Limitations

The idea is really simple and should work reliably. However there is still two configurations variables hardcoded in the wrapper. Open a bug / pull request if this does not work on your distribution / driver.

Library paths

The path of where the libGL.so library can be found on your system, usually /usr/lib.

Name of the Nix package which contains libGL.so

This package will be ignored by the wrapper. It is currently hardcoded as mesa-noglu but this can be fixed.
