Compiling ScummVM/Android
Compiling ScummVM for Android
This page describes how you build Android packages from the ScummVM source tree.
Mandatory tools
Use the SDK Manager to install:
- Android SDK Tools
- Android SDK Platform-tools
- SDK Platform Android 1.6, API 4
- SDK Platform Android 2.2, API 8
Set the ANDROID_SDK environment variable to the root directory of the SDK, and ANDROID_NDK to the root directory of the NDK.
Optional libraries
- MAD to play .mp3 audio files
- Tremor (lowmem branch) to play .ogg audio files
- FLAC to play lossless .flac files
Again, you have two options:
Precompiled binaries
Get this archive and extract it to e.g. /opt/android.
Build the libraries yourself
Here's a a simple script to set up a shell for crosscompiling:
#!/bin/sh
PREFIX=${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-
export CC=${PREFIX}gcc
export CXX=${PREFIX}g++
export AS=${PREFIX}gcc
export LD=${PREFIX}gcc
export AR=${PREFIX}ar cru
export RANLIB=${PREFIX}ranlib
export STRIP=${PREFIX}strip
export OBJCOPY=${PREFIX}objcopy
export MACHDEP="--sysroot=$ANDROID_NDK/platforms/android-4/arch-arm -g -mandroid -mthumb-interwork"
export CFLAGS="${MACHDEP} -Os -Wall -mandroid -msoft-float -march=armv5te -mtune=xscale"
export CXXFLAGS="${CFLAGS}"
export LDFLAGS="${MACHDEP}"
echo "./configure --host=arm --prefix=/opt/android/3rd-android-4-armeabi"
Save it to a file (like android-4-eabi.sh) and run
. ./android-4-eabi.sh
in your shell. Build systems should now use the correct tools.
Tremor
Get a SVN checkout (r17852. as of this writing):
svn co http://svn.xiph.org/trunk/Tremor
configure it:
./autogen.sh --host=arm --prefix=/opt/android/3rd-android-4-armeabi --enable-low-accuracy --enable-64kHz-limit
and finally build & install it:
make make install
FLAC
Get a tarball of the latest stable version here (v1.2.1 as of this writing) and extract it.
configure it:
./configure --prefix=/opt/android/3rd-android-4-armeabi --disable-largefile --disable-thorough-tests --disable-doxygen-docs --disable-xmms-plugin --disable-cpplibs --disable-ogg --disable-oggtest --disable-rpath
and build & install the required parts:
make -C src/libFLAC make -C src/libFLAC install make -C include install
Compiling
The Android port can be compiled with the configure script. The most basic way to accomplish this is to run:
./configure --host=android --enable-plugins --default-dynamic make
The script supports various arguments, which you can use to en- or disable features, see ./configure --help.
If you want support for additional libraries, you need cross-compiled binaries. If you followed the above description and have those libraries in /opt/android/3rd-android-4-armeabi, the configure command line would look like this:
./configure --host=android --enable-plugins --default-dynamic --with-tremor-prefix=/opt/android/3rd-android-4-armeabi --with-mad-prefix=/opt/android/3rd-android-4-armeabi --with-flac-prefix=/opt/android/3rd-android-4-armeabi
