復制內容保存為compiler-gcc5.h，放在要編譯內核模塊的內核代碼的include/linux下。

Welcome to the mykernel!

It is a platform to write your own OS kernel,its based on Linux Kernel 3.9.4 source code.

Set up this platform

sudo apt-get install qemu # install QEMU

sudo ln -s /usr/bin/qemu-system-i386 /usr/bin/qemu

wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.9.4.tar.xz # download Linux Kernel 3.9.4 source code

wget https://raw.github.com/mengning/mykernel/master/mykernel_for_linux3.9.4sc.patch # download mykernel_for_linux3.9.4sc.patch

xz -d linux-3.9.4.tar.xz

tar -xvf linux-3.9.4.tar

cd linux-3.9.4

patch -p1 < ../mykernel_for_linux3.9.4sc.patch

make allnoconfig

make

qemu -kernel arch/x86/boot/bzImage?

從qemu窗口中您可以看到my_start_kernel在執行，同時my_timer_handler時鐘中斷處理程序周期性執行。

cd mykernel 您可以看到qemu窗口輸出的內容的代碼mymain.c和myinterrupt.c

當前有一個CPU執行C代碼的上下文環境，同時具有中斷處理程序的上下文環境，我們初始化好了系統環境。

您只要在mymain.c基礎上繼續寫進程描述PCB和進程鏈表管理等代碼，在myinterrupt.c的基礎上完成進程切換代碼，一個可運行的小OS kernel就完成了。

start to write your own OS kernel,enjoy it!
