Missing (or bad) header file: ghc/utils/unlit/fs.h

[danwdart]

Following the instructions on the 8.8 branch using 8.8, despite the --local-bin-dir option not working in stack, I get:

Cabal-simple_mPHDZzAJ_3.0.1.0_ghc-8.8.2: Missing dependency on a foreign
library:             
* Missing (or bad) header file: ghc/utils/unlit/fs.h

This seems to have been taken out from ghc 2 years ago at ghc/ghc@4de585a#diff-cb0536dc6dae54d28ea6f9f45caf033d - which breaks the build.

Try running utils/makePackages.sh first. That got me past that problem.

[danwdart]

I tried that but it only helps me on 8.6, not 8.8.

[yobson]

Well that is so strange. Did you change the branch before or after submoduling? I don't know if the order matters

[danwdart]

I cloned as the branch so didn't need to change it.
Here's my old version trying to fix headers by re-cloning newer versions of dependencies, as a Dockerfile:

https://github.com/danwdart/dockers/blob/master/ghcjs/8.8/Dockerfile

(although I'd prefer it as nix now, but one step at a time)

Edit: it dies at stack install stage, and don't even think of using Docker Hub, it doesn't provide enough memory :p

I've just got GHCJS 8.8 to build. My method was:

$ [enstall emsdk etc]
$ git clone https://github.com/ghcjs/ghcjs.git
$ cd ghcjs
$ git branch ghc-8.8
$ git submodule update --init --recursive
$ ./utils/makePackages.sh
$ cabal v2-install --overwrite-policy=always --install-method=copy --installdir=inplace/bin

Now I lie a little bit. I had to change 3 file in ghc to get the build to finish. But one step at a time!

[danwdart]

I think that's the critical bit we're after :p
