Dockerfile and config for cross compiling Haskell to run on Raspberry Pi

README.md

Dockerfile to cross compile Haskell to Raspberry Pi

Follow the instructions by zw3rk to get the sysroot from your Raspberry Pi for the libraries:

  mkdir sysroot
  rsync -rzLR --safe-links \
      pi@raspberrypi:/usr/lib/arm-linux-gnueabihf \
      pi@raspberrypi:/usr/lib/gcc/arm-linux-gnueabihf \
      pi@raspberrypi:/usr/include \
      pi@raspberrypi:/lib/arm-linux-gnueabihf \
      sysroot/

Build the container with:

docker build -t ghc-to-rpi .

Then run it with:

docker run --rm -it -v $(pwd)/sysroot/:/rpi/sysroot/ ghc-to-rpi

And you can now cross-compile with

arm-linux-gnueabihf-ghc
