UEFI-1搭建环境

1.准备工作：
Build environment :Microsoft Windows
NASM
iasl
VS2017 安装选项如下图

2.环境变量
setx NASM_PREFIX=C:\nasm
path中加入
C:\ASL
C:\nasm
Python 2.7.10 或更高版本仍可与PYTHON_HOME<最新的要用PYthon3.8>
Python_HOME=C:\Python27
3.将code 从远程拉取下来并checkout 出2018版本
4.C盘下新建一个文件夹这里取名为UEFIWORKSPACE将code解压到这里，解压后的路径C:\UEFIWORKSPACE\EDK2\Conf
5.新建一个批处理文件testbuild.bat

set WorkSpace=C:\UEFIWORKSPACE
SET EDK_TOOLS_PATH=C:\UEFIWORKSPACE\EDK2\BaseTools
SET CONF_PATH=C:\UEFIWORKSPACE\EDK2\Conf
SET PACKAGES_PATH=C:\UEFIWORKSPACE\EDK2;C:\UEFIWORKSPACE\edk2-libc;C:\UEFIWORKSPACE\EDK2\MdeModulePkg

6.cmd运行以下指令

testbuild.bat
edk2\edk2setup.bat
build -a IA32 -p OvmfPkg\OvmfPkgIa32.dsc -D DEBUG_ON_SERIAL_PORT

至此build成功
VS2017中选择文件-》新建-》从现有代码创建项目，下图项目名称随意

1位置：

cd /D C:\UEFIWORKSPACE
    SET WORKSPACE=C:\UEFIWORKSPACE\
    SET EDK_TOOLS_PATH=C:\UEFIWORKSPACE\EDK2\BaseTools
    SET CONF_PATH=C:\UEFIWORKSPACE\EDK2\Conf
    SET PACKAGES_PATH=C:\UEFIWORKSPACE\EDK2;C:\UEFIWORKSPACE\edk2-libc
    call edk2/edksetup.bat
    call build.bat -a IA32 -p OvmfPkg\OvmfPkgIa32.dsc  -D DEBUG_ON_SERIAL_PORT

2位置

    cd /D C:\UEFIWORKSPACE
    SET WORKSPACE=C:\UEFIWORKSPACE\
    SET EDK_TOOLS_PATH=C:\UEFIWORKSPACE\EDK2\BaseTools
    SET CONF_PATH=C:\UEFIWORKSPACE\EDK2\Conf
    SET PACKAGES_PATH=C:\UEFIWORKSPACE\EDK2;C:\UEFIWORKSPACE\edk2-libc
    call edk2/edksetup.bat
    call build.bat -a IA32 -p OvmfPkg\OvmfPkgIa32.dsc  -D DEBUG_ON_SERIAL_PORT clean

3位置

    cd /D C:\UEFIWORKSPACE
    SET WORKSPACE=C:\UEFIWORKSPACE\
    SET EDK_TOOLS_PATH=C:\UEFIWORKSPACE\EDK2\BaseTools
    SET CONF_PATH=C:\UEFIWORKSPACE\EDK2\Conf
    SET PACKAGES_PATH=C:\UEFIWORKSPACE\EDK2;C:\UEFIWORKSPACE\edk2-libc
    call edk2/edksetup.bat
    call build.bat -a IA32 -p OvmfPkg\OvmfPkgIa32.dsc  -D DEBUG_ON_SERIAL_PORT clean
    call build.bat -a IA32 -p OvmfPkg\OvmfPkgIa32.dsc  -D DEBUG_ON_SERIAL_PORT

关于调试的配置：图中命令处为QEMU运行程序《注意：此处不加.exe 会出错！！！》，工作目录为qemu运行程序的目录《此处为绝对路径地址，末尾要加\注意：此处不加\ 会出错！！！》，

至此vs20017关于uefi的环境搭建完毕.<本文参考UEFI编程与实践>
