Environment construction

First step ：

download EDK2

https://sourceforge.net/projects/edk2/files/latest/download?source=files

  The second step ：

Will download UDK2015.Complete.MyWorkSpace Medium BaseTools(Windows).zip Unzip it to the working directory defined by you , for example ：E:\code\edkWorkSpace\

  The third step ：

take UDK2015.Complete.MyWorkSpace Files in package , The specific path is as follows （UDK2015.Complete.MyWorkSpace\UDK2015.MyWorkSpace.zip\MyWorkSpace\） Unzip all to the working directory (E:\code\edkWorkSpace\)

  Step four ：

To website https://www.acpica.org/downloads   download asl compiler （ Optional ）

Step five ：

perform edksetup.bat --nt32

  Step six ：

edit E:\code\edkWorkSpace\Conf\target.txt Medium TOOL_CHAIN_TAG = VS2010x86,（ The compiler you are currently using ）, Save and execute    build   Instructions

  Step seven ：

perform build run can Open the interface of simulation software .

standard C Addition of modules

  Use git clone https://github.com/tianocore/edk2.git  Download the code locally （ File size in 230M about ）

StdLib There are items containing the standard library （AppPkg, StdLib, and StdLibPrivateInternalFiles.）, Need to copy to E:\code\edkWorkSpace\ Under the table of contents

Compile with instructions ： build -a X64 -p AppPkg\AppPkg.dsc

If you need to make the files in the standard library cheap and available in the virtual machine （SecMain） Run in , After research, it is found that \AppPkg\AppPkg.dsc The following changes are made in

#OUTPUT_DIRECTORY = Build/AppPkg
OUTPUT_DIRECTORY = Build/NT32IA32

If you compile your own test program , You need to in \AppPkg\AppPkg.dsc Add your own part to it （ The underlined parts below ）. for example ：

[Components]

#### Sample Applications.
  AppPkg/Applications/Hello/Hello.inf        # No LibC includes or functions.
  AppPkg/Applications/Main/Main.inf          # Simple invocation. No other LibC functions.
  AppPkg/Applications/Enquire/Enquire.inf    #
  AppPkg/Applications/ArithChk/ArithChk.inf  #
  AppPkg/Applications/Main_test/Main.inf

Then compile with instructions ：build -a X64 -p AppPkg\AppPkg.dsc -m AppPkg\Applications\Main_test\main.inf ( Suppose your program path is AppPkg\Applications\Main_test\ Next )

In the use of build run  Command to run the simulator program .
