Question

我试图在android lollipop上运行修改过的android内核。我下载了Android sdk api-22 x86并使用以下命令编译了金鱼：

$ 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

使用上面的命令生成了arch/x86/boot/bzImage并且编译成功完成。

当我尝试使用

运行自定义编译内核的模拟器时

$ ./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

Please make sure you've got updated system images and do not force the specific kernel image together with the engine version

Answer 1

尝试编译金鱼v3.10或3.18，这些可以在这里找到 - https://android.googlesource.com/kernel/goldfish/ 正如您在输出中看到的那样，当模拟器需要＆gt; = 3.10时，您正在编译3.4内核。
