hey everyone! i am extremely new to nixos. i am trying to make a dev environment shell for compiling the julia compiler. Julia uses Makefiles to fetch external dependencies and then build them locally (this is doable but causes a lot of rebuilds everytime). You can avoid it by settings a flag which will download binaries for those dependencies instead of source but thats obviously wont work on nixos. Julia’s Makefile also provides flags to use system depencies instead of building/downloading its own. I am trying to setup that.
# flake.nix
{
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixos-24.11";
};
outputs =
{ self, nixpkgs }:
let
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
fhs = pkgs.buildFHSEnv {
name = "julia-fhs-env";
strictdeps = true;
targetPkgs =
pkgs: with pkgs; [
gnumake
llvmPackages.libunwind
libnghttp2
openlibm
# .....
];
runScript = "bash";
};
in
{
devShells.${system}.default = fhs.env;
};
}
I created this flake file and also setup the Makefile flag to use system libs. After compiling ( which i am able to do successfully). I run the julia binary and i get this:
ERROR: Unable to load dependent library /home/prashant/Proj/fork/usr/bin/../lib/libopenlibm.so
Message:/home/prashant/Proj/fork/usr/bin/../lib/libopenlibm.so: cannot open shared object file: No such file or directory
The ./usr directory was created by julia during compilation.

I created a dev shell with all the required libs (compile time and runtime) but julia is unable to find them? how can i get around this?
I have also tried using nix-ld with all the deps required.
Thank you!
