Build script for building ghc cross compilers targeting Android. This
script wraps up all the hacks and tweaks that are currently needed to
get a working ghc android crosscompiler. It will download the Android
NDK, the iconv library, the ncurses library and GHC itself as
required. If you already have the Android NDK you can put it in the
tarfiles directory or symlink it to this directory with the name
android-ndk-r10e and the build script will reuse it. If you already have a
ghc clone, you can use the mirror script to avoid doing a full
re-download during cloning.
To build a ghc-android compiler for both ARM and x86 execute:
./build
We recommend making the /opt/ directory writable for your user, temporarily at least.
By default this should give you a Cabal and GHC toolchain for ARM and x86 at:
/opt/ghc/bin
Add this directory to your PATH to use the cross compiler with the full target prefix.
Or add:
/opt/ghc/android-21/arm-linux-androideabi-4.9/arm-linux-androideabi/bin
to your PATH to use it without prefixes. There is also a cabal wrapper script in this directory that will cross compile packages with cable and add them to the ghc package-db.
You can change various variables via the environment to give you other configurations.
There is also a pre-configured x86 variation you can build like this:
./build --x86
If you want to build more than one configuration it is worth building a local mirror repo to speed up subsequent ghc clones. To build a mirror run:
./mirror {path to existing ghc clone}
During ./build the GHC repo is cloned into appropriate path, e.g.:
./build-android-21-arm-linux-androideabi-4.9/ghc
So the mirror path can become this:
./mirror build-android-21-arm-linux-androideabi-4.9/ghc
This will build a mirror that will automatically be used by the build script to speed up cloning.
The following configurations have been tested on an up-to-date Arch Linux install and are known to work. They are also known to work in Ubuntu 15.04.
* ghc-android-21-arm-linux-androideabi-4.9
* ghc-android-21-x86-4.9
Comments, patches and success reports are welcome.
