Build a debian package with cabal-debian

This article describes steps to build hakyll for debian. It uses libraries from debian repository. This is the preferred method because it uses the debian package repository.

cabal

apt-get --yes install haskell-platform cabal-debian haskell-devscripts ghc cabal-install
apt-get --yes install libghc-hakyll-doc
cd -P "$(mktemp -d)"
hakyll-init hakyll
dh_make -p haskell-hakyll_0.1.0.0 --indep --yes --createorig
cabal-debian
debuild -uc -us

Build hakyll with haskell stack

This method need more time and space because all libraries are recompiled. It works for all platforms with haskell-stack.

hakyll

aptitude install haskell-stack -y
su hakyll -c sh <<-"EOF"
        stack update
        stack setup --no-install-ghc
        stack install hakyll --compiler=ghc-8.0.1
        .local/bin/hakyll-init hakyll
EOF

Build pandoc with haskell stack

This builds pandoc with haskell stack.

pandoc

apt build-dep pandoc
stack install pandoc --resolver lts-9.20 --system-ghc
