ghcjs-m1.md
  1. Install rosetta, command line tools, etc.
  2. install gnu tar, gnu coreutils and bash from brew.
  3. compile this dylib https://github.com/yairchu/macos11-haskell-workaround
  4. clone ghcjs 8.6 branch and submodules
  5. install ghc 8.6 and cabal-install 2.4 with ghcup
  6. Edit the ghcup ghc wrapper script to add the dylib to DYLD_INSERT_LIBRARIES before invoking ghc
  7. Edit the ./ghc/aclocal.m4 and remove the underscore before AC_
  8. Edit the ./utils/makePackages.sh to use the brew-installed bash
  9. Run the makePackages script
  10. Run cabal install, have a cup of tea
  11. It will put a bunch of broken symlinks into your bin folder, remove them and replace them with wrapper scripts that invoke GHC from your dist-new/build directory similar to ghcup, being sure to set topdir to your root ghcjs directory
  12. Run ghcjs-boot -s ./lib/boot --no-prof --no-haddock
  13. Upgrade cabal to a more sane version (And ghc too if you want)
  14. Compile your project with cabal build --ghcjs
