macOS Mojave(10.14.3)系统QEMU虚拟机运行Clockwork OS

# 默认情况下，macOS的文件系统不区分大小写，我们需要手工创建一个区分大小写的分区

$ brew uninstall --ignore-dependencies binutils

# 安装依赖工具
$ brew install automake

$ brew uninstall --ignore-dependencies gawk
$ brew install gawk

# 目前编译gettext-0.19.8.1的时候写死依赖automake-1.15，但是最新的已经是automake-1.16，我们通过手工编译安装automake-1.15规避这个问题
$ wget http://ftp.gnu.org/gnu/automake/automake-1.15.tar.gz

编译 u-boot

$ cd /Volumes/ClockworkOS

编译 Linux 内核

$ cd /Volumes/ClockworkOS

$ brew install aria2

$ aria2c -c https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.2.tar.xz

# 也可本站下载 wget http://www.mobibrw.com/wp-content/uploads/2019/03/linux-4.14.2.tar.xz

$ export PATH="/Volumes/ClockworkOS/u-boot/tools:$PATH"
# 或者 brew install u-boot-tools

$ mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n "Linux kernel" -d arch/arm/boot/zImage uImage
$ cd /Volumes/ClockworkOS

$ brew install aria2

# 官方给出的这个地址下不到，只能用镜像地址 http://106.185.33.196/clockworkos_v0.3.img.bz2
$ aria2c -c http://clockworkpi.k15.net/clockworkos_v0.3.img.bz2

$ rm -rf clockworkos_v0.3.img

$ bzip2 -d -k -vvvv clockworkos_v0.3.img.bz2

# 替换镜像中的内核文件
$ hdiutil attach clockworkos_v0.3.img -mountpoint /Volumes/clockworkos_v0.3

$ echo y | cp -i /Volumes/ClockworkOS/linux-4.14.2/uImage /Volumes/clockworkos_v0.3/uImage

$ hdiutil detach /Volumes/clockworkos_v0.3

$ brew install qemu

$ qemu-img convert -f raw -O qcow2 clockworkos_v0.3.img clockworkos_v0.3.qcow2

手工编译 qemu

$ cd /Volumes/ClockworkOS

$ git clone https://github.com/qemu/qemu.git

$ cd qemu

# 从 qemu v2.1.0-rc1 开始，内存需要被映射到0x60000000开始的地址，更低的地址被映射为只读闪存，我们需要取消这种映射行为，否则执行的时候会报告错误
$ sed -i "" "s/\[VE_NORFLASHALIAS\] = 0/\[VE_NORFLASHALIAS\] = -1/g" hw/arm/vexpress.c

$ bash configure

$ make -j8

$ cd ..

# list supported machine `qemu-system-arm -machine help`

$ /Volumes/ClockworkOS/qemu/arm-softmmu/qemu-system-arm -M vexpress-a9 -m 1024M -kernel /Volumes/ClockworkOS/u-boot/u-boot -serial mon:stdio -nographic -sd clockworkos_v0.3.qcow2 -net nic,model=lan9118 -net user

可惜到这一步了，还是没办法成功运行系统。

  2. 你好，我最近也在弄macos跨平台编译linux内核，发现资料较少，且容易报错，方便加个qq吗，方便以后一起交流；我qq:1378400723
