Revision as of 10:03, 20 May 2013

These are my notes from trying to get OLA working on Android. This work was done on a Mac, but it should be the same on Linux with a few minor tweaks.

Toolchain

Download the Android NDK. Extract, this assumes you extracted to $HOME/android-ndk-XXX.

The NDK comes with a script to build a stand alone toolchain. We need to run it.

$ cd android-ndk-XXX
$ ./build/tools/make-standalone-toolchain.sh --system=darwin-x86_64 --platform=android-9 --install-dir=$HOME/android-toolchain/api9

Setup

We'll do all the work in $HOME/android

$ mkdir $HOME/android
# where we install libs to
$ mkdir $HOME/android/root

Setup env variables. Make sure you adjust the first line to use the version you downloaded.

$ export ANDROID_NDK_PATH=$HOME/android-ndk-XXX
$ export ANDROID_PLATFORM=9
$ export ANDROID_NDK_STANDALONE_TOOLCHAIN=~/android-toolchain/api$ANDROID_PLATFORM
$ export CPPFLAGS=""
$ export LDFLAGS=""
$ export PATH=$ANDROID_NDK_PATH/android-sdk-linux_x86/tools:$ANDROID_NDK_PATH/android-sdk-linux_x86/platform-tools:$ANDROID_NDK_STANDALONE_TOOLCHAIN/bin:$PATH

Test it out:

$ ls $ANDROID_NDK_PATH
$ ls $ANDROID_NDK_STANDALONE_TOOLCHAIN

Protobuf

You need to have protoc installed on your system first. To find out the correct path, run:

$ which protoc
/usr/local/bin/protoc

Then pass this path shown in the --with-protoc argument below.

Note: if you get an error like Invalid configuration `arm-linux-androideabi': system `androideabi' not recognized when running ./configure, you need to get new versions of config.sub and config.guess and replace the ones in each package. The latest can be downloaded from http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree


$ cd $HOME/android
$ wget <protobuf>
$ tar -zxf <protobuf>
$ cd protobuf-X.Y.Z
# fetch config.sub and config.guess if needed
$ ./configure   --target=arm-linux-androideabi-gcc  --with-protoc=/opt/local/bin/protoc
$ make
$ DESTDIR="$HOME/android/root" make install


TODO: Figure out how to package (or should we statically link to ola?)

UUID

OSSP UUID is quite old (2008) now so it doesn't cross compile well. Instead we'll use the libuuid from e2fsprogs.

Download from http://e2fsprogs.sourceforge.net/

$ cd $HOME/android
$ wget <e2fsprogs-url>
$ tar -zxf <e2fsprogs>
$ cd e2fsprogs-X.Y.Z
$ ./configure   --target=arm-linux-androideabi   
# we only want the libuuid bit
$ cd lib/uuid
$ make
$ DESTDIR="$HOME/android make install

Dependency Check

By this point you should have protobuf and uuid installed into ~/android/root. Check this is so:

$ ls ~/android/root/usr/local/include/
google uuid
ls ~/android/root/usr/local/lib/pkgconfig/
protobuf-lite.pc protobuf.pc      uuid.pc
$ export PKG_CONFIG_PATH="$HOME/android/root/usr/local/lib/pkgconfig"
$ pkg-config --list-all | grep uuid
uuid        uuid - Universally unique id library

OLA

export ac_cv_func_malloc_0_nonnull=yes
export PKG_CONFIG_PATH="$HOME/android/root/usr/local/lib/pkgconfig"
./configure --target=arm-linux-androideabi  --disable-http --disable-unittests
make
