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. It *must* be the same version that you build for android. To find out the correct path, run:
$ which protoc /usr/local/bin/protoc $ protoc --version libprotoc 2.5.0
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
You should also copy config.sub and config.guess to gtest/build-aux.
$ cd $HOME/android $ wget <protobuf> $ tar -zxf <protobuf> $ cd protobuf-X.Y.Z # fetch config.sub and config.guess if needed $ ./configure --host=arm-linux-androideabi --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 --host=arm-linux-androideabi --prefix=/usr/local # we only want the libuuid bit $ cd lib/uuid $ make $ DESTDIR="$HOME/android/root 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" $ export PKG_CONFIG_SYSROOT_DIR="$HOME/android/root" $ pkg-config --list-all | grep uuid uuid uuid - Universally unique id library $ pkg-config --cflags uuid -I/Users/simonn/android/root/usr/local/include/uuid
OLA
export ac_cv_func_malloc_0_nonnull=yes ./configure --host=arm-linux-androideabi --disable-http --disable-unittests --disable-libftdi --disable-spi --disable-osc make
