NixOS 22.11
Kernel: 5.15.67
I’ve been using Hyprland WM for a while, and on a recent system rebuild I began getting this error:
error: builder for '/nix/store/701fi2g81yhwsibbbv9r2qyql8lv7bx6-wlroots-hyprland-hidpi-2022-09-18_2ad25b1.drv' failed with exit code 1;

For full logs, run 'nix log /nix/store/701fi2g81yhwsibbbv9r2qyql8lv7bx6-wlroots-hyprland-hidpi-2022-09-18_2ad25b1.drv'
I looked at libdrm in nixpkgs and it looks it isn’t updated yet for 2.4.113. At this point, my assumption was to just try and bump the version for my system via this overlay:
libdrm = prev.libdrm.overrideAttrs (oldAttrs: rec {
pname = "libdrm";
version = "2.4.113";
src = final.fetchurl {
url = "https://dri.freedesktop.org/${pname}/${pname}-${version}.tar.xz";
sha256 = "sha256-f9frKWf2O+tGBvItUOJ32ZNIDQXvdd2Iqb2OZ3Mj5eE=";
};
});
With this overlay, I get this error:

If I overlay the meson option to be -Domap=enabled, I can make progress and get this error:
-Dwrap_mode=nodownload --prefix=/nix/store/8s7gfvriicangwlzcvv7n7j39zw6cank-libdrm-2.4.113 -Dnm-path=nm -Dinstall-test-programs=true -Domap=enabled

The option nm-path is added from a patch file in nixpkgs libdrm
As a test, if I “overlay” out the nm-path option, I get this error:
error: builder for '/nix/store/ry4b6ihnbp562vka9iyl0ng3arnn8a6c-libdrm-2.4.113.drv' failed with exit code 1;

At this point, I’m way out of my depth on how everything is impacting everything else, and there are a couple of questions I could use help on before I put more time on resolving these errors:
- Is an overlay even a reasonable approach to my original issue
missing libdrm-2.4.113? - Is there a problem with my implementation/writing of the overlay?
- Is
libdrm-2.4.113so different that it has a whole new set of meson flags and dependencies (cunit, cairo) that make thenixpkgsversion not usable? - Should I just continue trying to resolve these error messages by incrementing my overlay one by one? I’m not sure if there is even hope here…
- Are there glaring errors in my understanding of the whole system?
