【edk2 】【00】【windows环境搭建】

1. 下载edk2官方源码

• git clone git@github.com:tianocore/edk2.git
• cd edk2 & git submodule update --init --recursive
• 最近【2024.09.29】github访问比较慢，可能需要梯子加速，或者找国内的官方镜像

2. 安装编译工具

• python3
• iasl，添加路径到系统变量IASL_PREFIX=xxx
• nasm，添加路径到系统变量NASM_PREFIX=xxx
• 下载https://github.com/tianocore/edk2-BaseTools-win32，重命名为win32放到BaseTools\Bin目录下
• 下载http://www.cygwin.com/setup-x86_64.exe，添加路径到系统变量CYGWIN_HOME=xxx
• 将vs的clang工具链路径添加到系统变量，例如我的是CLANG_BIN=D:\VisualStudio\Software\VC\Tools\Llvm\x64\bin\
• 将vs工具链路径添加到系统变量，例如VS2019_PREFIX=D:\VisualStudio\Software\VC\Tools\MSVC\14.39.33519\

3. 尝试编译edk2工程

• 执行edksetup.bat，这一步会在Conf路径下生成tools_def.txt和target.txt
• 修改Conf\target.txt

TARGET_ARCH           = X64
...
TOOL_CHAIN_TAG        = VS2019

• 修改Conf\tools_def.txt

# *_*_*_ASL_FAMILY                   = INTEL
#
# *_*_*_ASL_PATH                     = D:\IASL\iasl.exe
#
####################################################################################
#
# Microsoft ACPI Source Language Compiler (Template)
#
####################################################################################
# *_*_*_ASL_FAMILY                   = MSFT
#
# *_*_*_ASL_PATH                     = D:\IASL\asl.exe

• 执行edksetup.bat rebuild
• 打开vs的编译命令行Developer Command Prompt for VS2022，然后进Conf文件夹，执行build命令，正常就可以进行编译了，编译完成可以看到如下打印：
