Remove jdk from R dependencies on arm platforms, as there is no free jdk on arm.

Motivation for this change

Despite being free itself, R is unavailable on aarch64 (wtihout setting allowUnfree to true) because it has an optional dependency on jdk and there is no free jdk package on arm platforms.

Things done

Made jdk optional, exclude it from the build inputs on aarch32 and aarch64.

  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Fits CONTRIBUTING.md.

Sorry, something went wrong.

I'm not sure if it's worth trying to do it differently, so that R can still depend on jdk on aarch64 if allowUnfree is true.

What does R need jdk for?

For "java support" apparently. https://cran.r-project.org/doc/manuals/r-release/R-admin.html#Java-support Looks like you can write R packages which can call java code or use java for graphics output.

I appear to have messed something up. This shouldn't trigger any rebuilds on other platforms.

It's probably the configureFlags which has changed.

Okay, not sure if this is a good idea or not. Building R on aarch64 would be great, but not supporting java is a tough tradeoff. I'll defer to someone who actually uses aarch64.

Looks good to me. I'm happy to see this PR merged assuming the test builds succeed.

Could you make "javaSupport" an arg here? Just to emphasize that you really don't need jdk with R anyway - we can just enable it by default on all other platforms.

Add javaSupport as an argument for R. Default to false on arm as there is no free jdk on arm.
