ghcHEAD (and the to be released GHC 9.6) have a JS backend that will replace ghcjs. We should get it to work in order to be able to get rid of the burdensome ghcjs 8.10.7. Ideally we can do this via the already existing pkgsCross.ghcjs infrastructure, but emscripten is proving to be a little annoying, so it may not be entirely possible.

Upstream build instructions.

This is probably blocked on #194634, as the JS backend requires llvm/llvm-project@2368f18.

Thanks! Should something like

nix-build -A pkgsCross.ghcjs.haskell.packages.ghcHEAD.colour

work in theory now?

I get these strange errors, as if the build doesn’t include all the necessary files:

~/build/nixpkgs $ nix-build -A pkgsCross.ghcjs.haskell.packages.ghcHEAD.colour
this derivation will be built:

@nomeata Interesting! We should find out if it is possible to build “dynamic” js objects or not with the JS backend – if not, we simply need to disable building shared objects for the js backend in generic-builder.nix which I may have neglected.

@nomeata We get further with #217168, but then hit llvm/llvm-project#60949.

@nomeata The JS backend can only build executables at the moment: https://gitlab.haskell.org/ghc/ghc/-/issues/23235#note_491474
