FINAL NOTE: The build adjustment done in this repo has been merged into Nixpkgs and GHC. Therefore, this repo is archived.
NOTE: nixpkgs is a moving target. This nix build has been tested against commit: ce2756f701886313180655a069202f3771621404 (2016-01-19)
This repo contains nix expressions to build ghc as a cross compiler for android. This automatically downloads sources for ghc-7.10.2 and android-ndk r10c. Right now, ghc compiler is built on x86-64 and will run on x86-64 targetting arm devices.
You can start nix-shell by
nix-shell shell.nix -I nixpkgs=(your nixpkgs directory)
Inside nix-shell, you can run
arm-unknown-linux-androideabi-ghc test.hs
For recent android, you should make executable binary as position independent executable. To do that, run
arm-unknown-linux-androideabi-ghc -fPIC -optl-pie test.hs
cabal can also be easily used.
cabal --with-ghc=arm-unknown-linux-androideabi-ghc --with-ld=arm-linux-androideabi-ld.gold --with-ghc-pkg=arm-unknown-linux-androideabi-ghc-pkg --ghc-options=-fPIC --ghc-options=-optl-pie configure
cabal build
Then you can push resultant executable by adb push and run it in adb shell.
Enjoy!
We also have a full android development shell made with buildFHSUserEnv to follow conventional filesystem hierarchy. Start the shell by
nix-shell adb-fhs-shell.nix -I nixpkgs=(your nixpkgs directory)
