Unfortunately /run/opengl-driver/lib contains neither libEGL.so nor libGLESv2.so. Do you know how to proceed? Does this means that there is just no support for these things from nVidia and I need another driver? FTR using exactly /nix/store/g1zgabwcbckwlsg2fiss1y3c1a6gas1v-nvidia-x11-340.24-3.12.26 Out of interest, is there a solution which would work both on NixOS and on setups with just nixpkgs? > On Fri, Aug 8, 2014 at 11:18 PM, Mateusz Kowalczyk <[email protected]> > wrote: > >> Hi, >> >> I have some software here that I'm trying to package.
