如何编译Android Goldfish 3.4内核并在模拟器上运行

Question

首先，我要告诉你我正在使用OS X 10.7.5的MAC工作。我正在尝试编译Goldfish 3.4内核并在模拟器上运行它。它编译得很好，但当我运行它时，模拟器打开并冻结了。当我执行“top”命令时，我可以看到模拟器疯狂地运行，但屏幕上没有任何显示。以下是我编译内核的方法：

git clone https://android.googlesource.com/kernel/goldfish.git
git checkout -t origin/android-goldfish-3.4 -b goldfish3.4
make ARCH=arm goldfish_defconfig
make ARCH=arm SUBARCH=arm CROSS_COMPILE=/Volumes/androidSpace/android_work/prebuilts/gcc/darwin-x86/arm/arm-eabi-4.6/bin/arm-eabi-

然后我通过以下方式运行模拟器

./emulator -debug init -kernel /Volumes/androidSpace/goldfish/goldfish/arch/arm/boot/zImage -system /Volumes/androidSpace/android_work/out/target/product/generic/system.img -ramdisk /Volumes/androidSpace/android_work/out/target/product/generic/ramdisk.img -avd firstAvd -wipe-data

以下是运行模拟器的调试输出的最后部分。

QEMU options list:
emulator: argv[00] = "./emulator64-arm"
emulator: argv[01] = "-android-hw"
emulator: argv[02] = "/Users/deathwillarrive/.android/avd/firstAvd.avd/hardware-qemu.ini"
Concatenated QEMU options:
./emulator64-arm -android-hw /Users/deathwillarrive/.android/avd/firstAvd.avd/hardware-qemu.ini

emulator: Could not open file: (null)/system/build.prop: No such file or directory
emulator: control console listening on port 5554, ADB on port 5555
emulator: sent '0012host:emulator:5555' to ADB server
emulator: ping program: /Volumes/androidSpace/android_work/out/host/darwin-x86/bin/./DDSs

输出结果在此处停止。有人知道构建3.4 goldfish内核的步骤吗？

目标“goldfish_defconfig”配置内核以适用于ARM 926，但现在模拟器配置为运行在cortex A8上，这是一个armv7架构。您应该使用“goldfish_armv7_defconfig”。

按照以下步骤构建模拟器的3.4内核：

git clone https://android.googlesource.com/kernel/goldfish.git
git checkout -t origin/android-goldfish-3.4 -b goldfish3.4

make ARCH=arm goldfish_armv7_defconfig
make ARCH=arm SUBARCH=arm CROSS_COMPILE=/Volumes/androidSpace/android_work/prebuilts/gcc/darwin-x86/arm/arm-eabi-4.6/bin/arm-eabi-

这应该能够构建一个3.4内核，然后您可以像这样运行它（我假设您的目录结构具有默认sdk ramdisk.img）。

./emulator -debug init -kernel /Volumes/androidSpace/goldfish/goldfish/arch/arm/boot/zImage -system /Volumes/androidSpace/android_work/out/target/product/generic/system.img -ramdisk /Volumes/androidSpace/android_work/out/target/product/generic/ramdisk.img -avd firstAvd -wipe-data
