Installation dependencies on NixOS about gr

[IngoMeyer441]

Hey @MikiVanousek,
I tried your example on a fresh NixOS (latest) installation and it works for me. How did you install julia and GR? I fetched Julia from the official home page (binary release) since the Julia package in NixOS is currently broken. I installed GR with the Julia package manager in the REPL (], add GR).

[MikiVanousek]

I used the Nixpkgs package julia_17-bin, which works, with the notable exception of Julia packages that ship binaries linked against specific dependency paths that are different on NixOS.

As for just downloading of the binary form the website, I somehow failed at this task. Did you do something besides running the binary in /bin of the downloaded folder? I get:

bash: /home/miki/dow/julia-1.7.3/bin/julia: No such file or directory

even though

/home/miki/dow/julia-1.7.3/bin/julia

[MikiVanousek]

In any case, I don't think there should be much of a difference between the manually downloaded Julia binary and the Nixpkgs one. Would you try it with the NixOS binary? You can obtain it with nix-shell -p julia-stable-bin.

The problem is caused by a hard-coded ELF interpreter path in the GR binaries. gksqt expects the interpreter to be located at /lib64/ld-linux-x86-64.so.2 which is not the case under NixOS. The official Julia binaries have the same problem, so for a quick and dirty fix I simply created a symlink at /lib64/ld-linux-x86-64.so.2 which was also the reason that gksqt started working.

[IngoMeyer441]

So the qksqt application either needs to be patched (see https://nixos.wiki/wiki/Packaging/Binaries#The_Dynamic_Loader) or GR should be installed from source. GR.jl can pick up an existing GR installation. However, I am new to NixOS. Is it possible to simple run a make install or must everything be installed with the Nix package manager?

[MikiVanousek]

I am not that well versed in NixOS packaging, but I think the best/most robust way would be to use Nix to package GR, which if you know what you are doing should not be too difficult.

[IngoMeyer441]

I have no experience with NixOS or Nix at all. For this issue, I set up my first virtual machine with NixOS. It would be great to have a guide for this.
