EDK2开发(1)-Ubuntu开发环境搭建

环境说明

使用 WSL2+VSCode 的组合进行开发，方便快捷

教程参考官方 Github 仓库 Wiki：Common instructions · tianocore/tianocore.github.io Wiki

环境搭建

更新工具链

sudo apt install build-essential uuid-dev iasl git  nasm  python-is-python3

• python-is-python3可以不装，自己做一个链接python->python3.8也行

从仓库拉取源码

基于区域封锁情况自行设置代理，或者从镜像站点拉取

bakaft@BakaFT-PC:~$ git clone https://github.com/tianocore/edk2.git
Cloning into 'edk2'...
remote: Enumerating objects: 370092, done.
remote: Total 370092 (delta 0), reused 0 (delta 0), pack-reused 370092

Resolving deltas: 100% (268196/268196), done.

拉完之后要初始化子模块

bakaft@BakaFT-PC:~/edk2$ git submodule update --init

编译 EDK2 工具链

EDK2 拥有自己的构建工具链

bakaft@BakaFT-PC:~/edk2$ make -C BaseTools

配置工作区环境变量

每次重启 Bash 还要重新设置一次

bakaft@BakaFT-PC:~/edk2$ . edksetup.sh 

构建测试

设置构建目标信息

编辑$CONF_PATH/target.txt

修改 20 行：

ACTIVE_PLATFORM       = MdeModulePkg/MdeModulePkg.dsc

54 行:

TOOL_CHAIN_TAG        = GCC5

尝试构建

build
# ....

- Done -
Build end time: 00:20:58, May.22 2022
Build total time: 00:00:45

构建完毕后即可看到编译好的文件

root@BakaFT-PC:~/edk2# ls Build/MdeModule/DEBUG_*/*/HelloWorld.efi
Build/MdeModule/DEBUG_GCC5/IA32/HelloWorld.efi

到这里就说明环境是没问题的了
