GHCJS

System setup where installing ghcjs was succeeded. In another system setup the steps could be different.

    OS: Manjaro 23.0.0 Uranos
    Kernel: x86_64 Linux 6.4.6-1-MANJARO
    DE: KDE 5.108.0 / Plasma 5.27.7

GHC-8.6 version for encoins project

  1. I use ghcup for tool management. Thus there should not exist (or be visible in a PATH) any alternative of cabal setup (for example in /home/$USERNAME/.cabal ) except ones that installed by ghcup. Also,no extra ghc-pkg setups, for example in /usr/bin PATH. Highly likely installed globally happy should have version 1.19.11. Likely, in your case there are another toolings installed with different version that slips into GHCJS compiling.

  2. GHCUP: GHC set to 8.6.5, Cabal set to 3.2.0.0

  3. git clone --branch ghc-8.6 https://github.com/ghcjs/ghcjs.git

  4. cd ghcjs

  5. git submodule update --init --recursive

  6. Replace _AC_PROG_CC_C99 with AC_PROG_CC_C99 in ghc/aclocal.m4 if you run into error:

     configure:6892: error: possibly undefined macro: _AC_PROG_CC_C99 If this token and others are legitimate, please use m4_pattern_allow

  7. ./utils/makePackages.sh

  8. cabal new-configure

  9. cabal new-build

  10. Make ghcjs-run visible by adding to utils/dist-newstyle-wrapper.sh the lines:

elif [ "$PGM" = "ghcjs-run" ]; then
  exec "$DISTDIR/ghcjs-run/ghcjs-run" ${1+"$@"}
  1. Make executables being global:
ln -sf `pwd`/utils/dist-newstyle-wrapper.sh /home/$USER/.local/bin/ghcjs && \
ln -sf `pwd`/utils/dist-newstyle-wrapper.sh /home/$USER/.local/bin/ghcjs-pkg && \
ln -sf `pwd`/utils/dist-newstyle-wrapper.sh /home/$USER/.local/bin/haddock-ghcjs && \
ln -sf `pwd`/utils/dist-newstyle-wrapper.sh /home/$USER/.local/bin/hsc2hs-ghcjs && \
ln -sf `pwd`/utils/dist-newstyle-wrapper.sh /home/$USER/.local/bin/ghcjs-boot && \
ln -sf `pwd`/utils/dist-newstyle-wrapper.sh /home/$USER/.local/bin/ghcjs-run
  1. ghcjs-boot -s ./lib/boot --no-haddock -j8 I turned off building haddock documentation with --no-haddock because of an error Haddock's resource directory does not exist! which could be fixed for sure.
