Я пытаюсь запустить модифицированное ядро Android на Android Lollipop. Я скачал Android sdk api-22 x86 и скомпилировал золотую рыбку, используя следующие команды:
$ git clone https://android.googlesource.com/kernel/goldfish.git
$ cd goldfish/
$ git checkout -t origin/android-goldfish-3.4 -b goldfish3.4
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/x86/i686-linux-android-4.6
$ export PATH=$(pwd)/x86_64-linux-android-4.7/bin:$PATH
$ export CROSS_COMPILE=x86_64-linux-android-
$ make ARCH=x86 CC="${CROSS_COMPILE}gcc -mno-android" goldfish_defconfig
$ make ARCH=x86 CC="${CROSS_COMPILE}gcc -mno-android" bzImage
Использование вышеуказанных команд сгенерировало arch/x86/boot/bzImage, и компиляция была успешно завершена.
Когда я попытался запустить эмулятор с скомпилированным ядром, используя
$ ./tools/emulator -debug init -kernel ~/Android_Project/goldfish/arch/x86/boot/bzImage -system ./system-images/android-22/google_apis/x86/system.img -ramdisk ./system-images/android-22/google_apis/x86/ramdisk.img -avd Nexus_S_API_22 -wipe-data -qemu -enable-kvm -show-kernel
