The generic_x86 board target provides basic services on
|
||||
very basic hardware. To build with generic_x86, you will
|
||||
need an appropriate kernel for your device (or emulation).
|
||||
|
||||
A1. Create a new top level directory and pull the AOSP repository
|
||||
mkdir $HOME/AOSP
|
||||
cd $HOME/AOSP
|
||||
repo init -u git://android.git.kernel.org/platform/manifest.git
|
||||
repo sync
|
||||
|
||||
A2. Copy in the buildspeck.mk
|
||||
cd $HOME/AOSP
|
||||
cp build/target/board/generic_x86/buildspec-generic_x86.mk buildspec.mk
|
||||
|
||||
A3. Copy in the kernel
|
||||
cd $HOME/AOSP
|
||||
cp ~/bzImage.your_device $HOME/AOSP/prebuilt/android-x86/kernel/kernel
|
||||
|
||||
A4. Build
|
||||
cd $HOME/AOSP
|
||||
source build/envsetup.sh
|
||||
lunch generic_x86-eng
|
||||
make -j8
|
||||
|
||||
The build will generate some image files whose format may or may not be correct for your
|
||||
device.
