編譯步驟：
1. Download android source
$ export ANDROID_ROOT=/home/kanamaru/ics-netwalker $ mkdir -p $ANDROID_ROOT $ cd $ANDROID_ROOT $ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.3_r1.1 $ repo sync -j8
2. Download kernel source
$ cd $ANDROID_ROOT $ wget http://netbook-remix.archive.canonical.com/updates/pool/public/l/linux-fsl-imx51/linux-fsl-imx51_2.6.28-15.50fsl1araneo19.tar.gz $ tar zxf linux-fsl-imx51_2.6.28-15.50fsl1araneo19.tar.gz
3. Apply androidzaurus patch
$ cd $ANDROID_ROOT $ wget https://github.com/androidzaurus/droidwalker/archive/master.zip $ unzip master.zip $ tar zxf androidzaurus-droidwalker-61b2290.tar.gz $ cd jaunty-arm $ patch -p1 < ../androidzaurus-droidwalker-61b2290/diff-araneo-android-2.6.28.patch $ patch -p1 < ../androidzaurus-droidwalker-61b2290/disable_double_buffering.patch $ patch -p1 < ../androidzaurus-droidwalker-61b2290/fbmem_8m.patch $ patch -p1 < ../androidzaurus-droidwalker-61b2290/build-wifi-defconfig.patch
4. Apply another patch
$ cd $ANDROID_ROOT $ wget http://brain.cc.kogakuin.ac.jp/research/files/ics/device_tk-netwalker-ics4.0.3-20120102.tgz $ tar zxf device_tk-netwalker-ics4.0.3-20120102.tgz $ $ANDROID_ROOT/device/tk/netwalker/patch/tk_patch.sh
5. Build kernel
$ cd $ANDROID_ROOT/jaunty-arm $ export ARCH=arm $ export CROSS_COMPILE=$ANDROID_ROOT/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- $ export PATH=$ANDROID_ROOT/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin:$PATH $ make netwalker_android_defconfig $ make zImage modules
6. Build android
$ cd $ANDROID_ROOT/ $ export ARCH=arm $ export CROSS_COMPILE=$ANDROID_ROOT/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- $ export PATH=$PATH:$ANDROID_ROOT/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin $ source build/envsetup.sh $ lunch full_netwalker-eng $ make -j8 $ $ANDROID_ROOT/device/tk/netwalker/image/netwalker-image.sh
P.S. 結果將存放在$ANDROID_ROOT/device/tk/netwalker/image/ics
