# Build it with Cabal:

Mario advises against building with Cabal as managing dependencies and upgrades to them is a pain. But for completeness lets try it.

These build steps were extracted from the `distribution/docker/x86_64-musl.dockerfile`. There are already scripts under `distribution/` folder to build for many different platforms. This is probably the easiest way
of doing it. But here is a more epxlicit step by step way for a Linux box.

Not that compared with the Dockerfile I had to remove static linking, it has `CABALOPTS="-f-export-dynamic -fembed_data_files --enable-executable-static -j4"`. Making a more portable statically linked binary is a bit tricky with Haskell, and that is why the Dockerfile builds on Alpine Linux to do that since it uses musl libc
which is a more standalone libc.

    curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
    export PATH="${PATH}:~/.ghcup/bin"

    ghcup install ghc 9.2.8 --set
    ghcup install cabal 3.10.1.0 --set    
    cabal update

    export CABALOPTS="-f-export-dynamic -fembed_data_files -j4"
    export GHCOPTS="-j4 +RTS -A256m -RTS -split-sections -optc-Os -optl=-pthread"

    cabal build $CABALOPTS --ghc-options="$GHCOPTS" --only-dependencies
    cabal build $CABALOPTS --ghc-options="$GHCOPTS"
