This repository contains build scripts and patches that can be used to build selected native libraries using the Android Native Development Toolkit (NDK). Often, existing libraries need small changes to the build system or simple tweaks to the source code to be usable on Android. This repository collects such tweaks for selected packages.
You will need the Android tools or SDK, as well as the Android NDK to build the packages.
- Install Android tools
- Install Android NDK into the directory of Android tools and rename to ndk
- Install cmake, git, and ant
- Set path to something like: PATH=SDK/tools:SDK/platform-tools:SDK/ndk:$PATH
To build all libraries, make sure the Android NDK is on your path and run build-all
in the top-level directory. The script will download release tarballs for individual
libraries from the internet.
Let's suppose you need to patch a package because it would not compile on
android. A common problem is that config.guess and config.sub are too old
and don't recognize the android platform.
Enter the package's directory and create patches subdirectory:
$ mkdir patches
Download config.guess and config.sub from savannah. Untar the package's source tarball.
Create a new patch:
$ quilt new 01-config_guess.patch
$ quilt add package/config.guess
Now replace the file with the downloaded version, then refresh the patch:
$ quilt refresh
After that repeat the same for config.sub. At the end delete the extracted source tarball and the subdirectory .pc and try to build the package.
Each time you want to add another modification to the topmost patch you can
just edit the file and rerun quilt refresh.
