macos m1下编译linux内核

2022-07-11 03:31:21  阅读:65  来源: 互联网

标签:opt macos make elf vmlinux m1 内核 linux homebrew


说明

结合网上一些资源并折腾了一段时间后才成功的。因为完全参考无法正常编译,记录一下供有需要的,希望能对其有所帮助

uboot也可以参考编译通过

macos版本

uname -a
Darwin finnmac-mini.local 21.5.0 Darwin Kernel Version 21.5.0: Tue Apr 26 21:08:29 PDT 2022; root:xnu-8020.121.3~4/RELEASE_ARM64_T8101 arm64

安装环境

brew install make
brew install aarch64-elf-gcc
brew install [email protected]

依赖环境

elf.h

个人在内核源码同级新建include目录,拷贝其中

编译步骤

/opt/homebrew/opt/make/libexec/gnubin/make ARCH=arm64 CROSS_COMPILE=aarch64-elf- defconfig

# 去掉CONFIG_KVM选项避免不必要的报错
# [ ] Virtualization  ----
/opt/homebrew/opt/make/libexec/gnubin/make ARCH=arm64 CROSS_COMPILE=aarch64-elf- menuconfig
  • 修改内核
diff --git a/scripts/mod/file2alias.c b/scripts/mod/file2alias.c
