Run-Time EGL Error: "Failed to Open Swrast" (Nix) -
1 context
i have private repo builds via nix (in case matters, repo haskell + stack project). in particular, repo has low-level graphics dependencies, including (at top level):
buildinputs = pkgs; [ mesa xorg.pixman wayland-protocols wayland xorg.libx11 dbus weston ]; and system i'm building repo on arch linux machine (with nix installed outside package manager).
2 problem
the program compiles fine, when launch soul-crushing run-time error:
loading module '/nix/store/98ipsxd20n5nw71q1kjpb5kyr55ysx7y-weston-2.0.0/lib/libweston-2/x11-backend.so' loading module '/nix/store/98ipsxd20n5nw71q1kjpb5kyr55ysx7y-weston-2.0.0/lib/libweston-2/gl-renderer.so' egl client extensions: egl_ext_client_extensions egl_ext_platform_base egl_khr_client_get_all_proc_addresses egl_khr_debug egl_ext_platform_wayland egl_ext_platform_x11 egl_mesa_platform_gbm libegl warning: dri2: failed authenticate libegl warning: dri2: failed open swrast (search paths /run/opengl-driver/lib/dri) failed initialize display egl error state: egl_not_initialized (0x3001) socket: wayland-0 program-name: user error (failed compiling shader shader {shaderid = 0}) 3 inelegant solution
the issue it's searching in /run/opengl-driver/lib/dri, nixos specific path. in fact -- when build , launch program on secondary nixos system, compiles , runs fine.
a horrendous hack fix issue on non-nixos systems run:
sudo ln -s /nix/store/*-mesa-noglu-*-drivers /run/opengl-driver question: there more elegant, nixish solution problem?
sorry, open problem @ time of writing.
