我的解答思路和尝试过的方法

pip install brotli
sudo apt install build-essential uuid-dev
sudo apt install acpica-tools
环境都按照了，网上说出现这个错误需要下载这些，但是依然报错

我想要达到的结果

1 我一直是在ubuntu 16上搭建x86环境，因为用得比较少。更多的时候，是在windows10上用VS搭建的。Ubuntu 20我没有去试过，因为不想被各种编译器版本的问题缠着；

2 tianocore社区这块，写搭建环境的部分，不是特别好。我现在开发arm的环境，是在ubuntu 18上的，可以参考：
https://developer.arm.com/tools-and-software/open-source-software/firmware/edkii-uefi-firmware/building-edkii-uefi-firmware-for-arm-platforms
对在ubuntu 20上搭建可能会有所帮助（主要看前面工具部分）；
brotli通过git更新submodules实现的，不用安装；acpi工具需要重新编译。

3 拷贝我之前的笔记，看看是否有帮助（ubuntu 16上安装的）

1.2 准备EDK2，edk2-libc,edk-platform
 准备工具：bash$ sudo apt-get install build-essential uuid-dev iasl git gcc-5 nasm python3-distutils
 实际上还缺一些：sudo apt install bison build-essential flex git uuid-dev  python3-distutils
( python3-distutils-extra)
  git clone git@gitee.com:luobing4365/edk2-libc.git
  git clone git@gitee.com:luobing4365/acpica.git
  git clone --branch edk2-stable202108 git@gitee.com:luobing4365/edk2.git

1.2.1 edk2的submodule处理
  修改地址为自己的(.gitmodule)：
[submodule "CryptoPkg/Library/OpensslLib/openssl"]
        path = CryptoPkg/Library/OpensslLib/openssl
        url = https://gitee.com/luobing4365/openssl.git
[submodule "SoftFloat"]
        path = ArmPkg/Library/ArmSoftFloatLib/berkeley-softfloat-3
        url = https://gitee.com/luobing4365/berkeley-softfloat-3.git
[submodule "UnitTestFrameworkPkg/Library/CmockaLib/cmocka"]
        path = UnitTestFrameworkPkg/Library/CmockaLib/cmocka
        url = https://gitee.com/luobing4365/cmocka.git
[submodule "MdeModulePkg/Universal/RegularExpressionDxe/oniguruma"]
        path = MdeModulePkg/Universal/RegularExpressionDxe/oniguruma
        url = https://gitee.com/luobing4365/oniguruma.git
[submodule "MdeModulePkg/Library/BrotliCustomDecompressLib/brotli"]
        path = MdeModulePkg/Library/BrotliCustomDecompressLib/brotli
        url = https://gitee.com/luobing4365/brotli.git
[submodule "BaseTools/Source/C/BrotliCompress/brotli"]
        path = BaseTools/Source/C/BrotliCompress/brotli
        url = https://gitee.com/luobing4365/brotli.git
        ignore = untracked
[submodule "RedfishPkg/Library/JsonLib/jansson"]
        path = RedfishPkg/Library/JsonLib/jansson
        url = https://gitee.com/luobing4365/jansson.git
进入edk2,git submodule update --init 

1.2.2  编译acpica 
    export WORKSPACE=$PWD
    make -C $WORKSPACE/acpica 

1.2.3 工作路径和平台路径
  新建myexport.sh,填入以下内容：
  export WORKSPACE=$PWD
  export PACKAGES_PATH=$PWD/edk2:$PWD/edk2-libc
  export IASL_PREFIX=$PWD/acpica/generate/unix/bin/
  export PYTHON_COMMAND=/usr/bin/python3

1.2.4 编译基本工具 
  
robin@robin-VirtualBox:~/jmuefi$ source ./myexport.sh 
robin@robin-VirtualBox:~/jmuefi$ cd edk2/
robin@robin-VirtualBox:~/jmuefi/edk2$ make -C BaseTools/

1.2.5 编译EmulatorPkg
robin@robin-VirtualBox:~/jmuefi$ source ./myexport.sh
robin@robin-VirtualBox:~/jmuefi$ cd edk2/
robin@robin-VirtualBox:~/jmuefi/edk2$. edksetup.sh
修改Conf/target.txt
GCC5 X64
robin@robin-VirtualBox:~/jmuefi/edk2$ build –D ADD_SHELL_STRING
(stable201108的模拟器Host好像无法运行)

1.2.6 一些可能的错误：
   A: 缺少sys/cdefs.h    sudo apt install libc6-dev-i386
   B 缺少X11/Xlib.h  $sudo apt-get install libx11-dev libx11-dev:i386
   C 缺少X11/extensions /XShm.h    sudo apt-get install libxext-dev libxext-dev:i386

以上过程用Ubuntu16.04搭建成功，但Ubuntu20.04还是不行

Toolchain = GCC5
明明是GCC5为啥参数那里写的是GCC48
尝试
build -p edk2/EmulatorPkg/EmulatorPkg.dsc -t GCC5 -a X64
