Installing Haskell as an extra compiler

[jeroenvanderzwam]

Dear developers,

I have been trying to install Haskell as an extra compiler within the chroot. Underneath is the code I have added to the chroot-and-tar.sh

apt-get update -y
apt-get install -y --no-install-recommends \
        curl \
        libnuma-dev \
        zlib1g-dev \
        libgmp-dev \
        libgmp10 \
        git \
        wget \
        lsb-release \
        software-properties-common \
        gnupg2 \
        apt-transport-https \
        gcc \
        autoconf \
        automake \
        build-essential

# gpg --batch --keyserver keyserver.ubuntu.com --recv-keys 7D1E8AFD1D4A16D71FADA2F2CCC85C0E40C06A8C

curl https://downloads.haskell.org/~ghcup/x86_64-linux-ghcup > /usr/bin/ghcup
chmod +x /usr/bin/ghcup
# ghcup config set gpg-setting GPGStrict

GHC=latest
CABAL=latest
CHROOTDIR="/chroot/domjudge"

ghcup -v install ghc --isolate "$CHROOTDIR/usr/local/lib" --force ${GHC}
# ghcup -v install ghc --force ${GHC}
ghcup -v install cabal --isolate "$CHROOTDIR/usr/local/lib" --force ${CABAL}
# ghcup -v install cabal --force ${CABAL}

# chroot /chroot/domjudge ln -s -f /usr/local/lib/bin/ghc-9.8.1 /usr/local/bin/ghc

But it seems that when I try to compile with the domserver the ghc command is not recognized.

Later I just tried to install ghc and cabal manually within the docker container. But this still does not help.

If somebody could help me I would be very grateful.

You should install ghc inside the chroot. I'm not really familiar with our docker packaging, but I assume that just adding it to that script doesn't do so. Have a look at the dj_make_chroot script. Also note that only a few directories from the chroot are mounted by default in the sandbox, so if ghc needs files from other directories, then you may need to adjust that. See the judge/chroot-start-stop.sh script in the main repo.

FYI, for questions please use our slack chat or mailinglist, as this is meant for bug reports and feature requests.

I'll close this one as its not a bug.
