Linux 内核编译
1、工具链
2、 内核源码
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git --depth=1
3、内核配置
3.1、使用deconfig
armhf
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig
arm64
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make defconfig
3.2、手动配置
armhf
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
arm64
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make menuconfig
4、内核编译
4.1、zImage/ Image
armhf
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4 zImage
arm64
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j4 Image
编译结束后，应该在arch/arm/boot（armhf）中生成zImage，或者在arch/arm64/boot（arm64）中生成Image
4.2、设备树
armhf
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4 dtbs
arm64
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j4 dtbs
现在，您应该在arch/arm/boot/dts（armhf）或arch/arm64/boot/dts（arm64）中有一个与你的设备匹配的设备树二进制文件（.dtb）
4.3、模块
armhf
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4 modules
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- INSTALL_MOD_PATH=<any-path-you-like> make modules modules_install
arm64
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j4 modules
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH=<any-path-you-like> make modules modules_install
After the build succeeds, you can find the modules in the supplied INSTALL_MOD_PATH directory.
4.4、头文件
armhf
ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- INSTALL_HDR_PATH=<any-path-you-like> make headers_install
arm64
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_HDR_PATH=<any-path-you-like> make headers_install
将INSTALL_HDR_PATH更改为你想要将头文件安装到的路径，例如，/usr or <some_prefix>/usr
