Cannot run on NixOS

[ThibaultLemaire]

I have managed to compile on NixOS, but the resulting executable can't find its runtime dependencies (specifically libXrandr.so.2 but I suspect the issue will happen again with other dependencies).

Command:

nix-shell -p rustup pkg-config openssl alsaLib xorg.libX11 xorg.libXrandr cmake python3 freetype expat --run 'cargo run'

Output:

    Finished dev [unoptimized + debuginfo] target(s) in 6.16s
     Running `target/debug/space-menace`

(This is a dev build, but the same happens with a release build)

This is the first Rust project I try to compile on NixOS, I'll ask on the Nix Matrix room for insights.

HINT: The following command reveals all the run-time dependencies, AFAIK:

$ ldd <binary>

For instance:

$ ldd /usr/bin/docker
    linux-vdso.so.1 =>  (0x00007ffde665a000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f34e9df0000)

I think I'll try to take inspiration from veloren/veloren!506 to write a working derivation

[ThibaultLemaire]

Wait, could it have to do with vulkan? My GPU doesn't support vulkan.

[erlend-sh]

That would be it. We do not yet support OpenGL.

[ThibaultLemaire]

Closing as irrelevant. As far as I could test compilation is successful on NixOS. The support for OpenGL is another issue.
