BaseTools/ReadMe.txt - SHIFTPHONES/android_bootable_bootloader_edk2 - Gitiles

 This directory contains the next generation of EDK II build tools and template files.
 Templates are located in the Conf directory, while the tools executables for
 Microsoft Windows 32-bit Operating Systems are located in the Bin\Win32 directory, other
 directory contatins tools source.

 1. Build step to generate the binary tools.

 === Windows/Visual Studio Notes ===

 To build the BaseTools, you should run the standard vsvars32.bat script.

 In addition to this, you should set the following environment variables:

  * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree
  * BASE_TOOLS_PATH - The directory where the BaseTools source is located.
    (It is the same directory where this README.txt is located.)
  * PYTHON_FREEZER_PATH - Path to where the python freezer tool is installed

 After this, you can run the toolsetup.bat file, which is in the same
 directory as this file.  It should setup the remainder of the environment,
 and build the tools if necessary.

 Please also refer to the 'BuildNotes.txt' file for more information on
 building under Windows.

 === Unix-like operating systems ===

 To build on Unix-like operating systems, you only need to type 'make' in
 the base directory of the project.

 === Ubuntu Notes ===

 On Ubuntu, the following command should install all the necessary build
 packages to build all the C BaseTools:

   sudo apt-get install build-essentials uuid-dev

 === Python sqlite3 module ===
 On Windows, the cx_freeze will not copy the sqlite3.dll to the frozen
 binary directory (the same directory as build.exe and GenFds.exe).
 Please copy it manually from <PythonHome>\DLLs.

 The Python distributed with most recent Linux will have sqlite3 module
 built in. If not, please install sqlit3 package separately.

 2. The binary tools will be updated only after passing developer testing.

 Current state of the tools is Proto-Type - not all tool functions have been implemented
 and there may be bugs in these tools.  These tools are under constant development at
 this time.

 3. Tool usage introduction.
 BaseTools Simple Usage:
 1) Change the directory to the EDK2 root directory, where the edksetup.bat is
 2) Run "edksetup.bat NewBuild"
 3) Set the ACTIVE_PLATFORM to your desired platform description file
    (%WORKSPACE%\Conf\target.txt)
 4) To build platform, run "build" command in non-module directory
 5) To build module individually, run "build" command in module directory, i.e. where the
    *.inf file is

 Notes:
 1) The tree structure generated by build tools is similar to Ant build system.
 2) Makefile can be called directly by nmake for both top level platform and module. But
    after you call "nmake cleanall", you have to call "build" command to rebuild platform
 	 or modules because the AutoGen.* files have been be removed. The "makefile" itself
 	 cannot generate AutoGen.* files. Only "build" command can.
 3) All .exe binary file including C and python tools are generated from:
     r1911 <buildtools_project>\BaseTools\Source\.

 Brief usage for Migration Tool MigrationMsa2Inf.exe:
 1. Command line format:
   MigrationMsa2Inf [options]
 2. Input Files:
   A syntactically valid MSA file
 3. Output Files:
   An extended INF file with possible auto-generated EntryPoint.c, CommonHeader.h/CommonHeader.txt, depending on options and module contents.
 4. Prerequisite:
    a. The workspace directory must be specified either by environment variable or -w option.
    b. The Framework Database file must exist to specify the available packages in current workspace.
       Two possible locations are: (The first location overrides the second)
             $(WORKSPACE)\Tools\Conf\FrameworkDatabase.db
             $(WORKSPACE)\Conf\FrameworkDatabase.db.
       The <PackageList> field in FrameworkDatabase.db lists all available packages in current workspace.
       One example:
       <PackageList>
         <Filename>MdePkg/MdePkg.nspd</Filename>
         <Filename>MdeModulePkg/MdeModulePkg.spd</Filename>
         <Filename>IntelFrameworkPkg/IntelFrameworkPkg.spd</Filename>
       </PackageList>
       The package list in FrameworkDatabase.db is important to the final quality of migration:
       (1) It suggests the new package location: Translate package dependency Guid in MSA to Workspace relative path.
          If the package dependency Guid cannot be found in current workspace a warning message is raised.
       (2) It collects the Protocol/Guid/Ppi GuidCName a package contains.
          The GuidCName acts as "clue" to add e.g. #include <Protocol/DiskIo.h> in CommonHeader.h

 5. Example:
    WORKSAPCE has already been set: $(WORKSPACE) = c:\work\EdkII.

    a. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -o c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.inf
    b. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -a
    Example a & b are equivalent to migrate WinNtThunk driver from EDKII to EDKII' code base.

    c. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -a -c
    The extra "-c" option performs several hardcode mapping due to the naming change in EDKII':
       OldMdePkg Guid -> MdePkgGuid,
       EdkModulePkg Guid -> MdeModulePkgGuid,
       EdkGraphicsLib -> GraphicsLib
       HiiLib -> HiiLibFramework
       ...

    d. MigrationMsa2Inf -f c:\work\EdkII\Nt32Pkg\WinNtThunkDxe\WinNtThunk.msa -m
    The extra "-m" option suppresses the generation of "CommonHeader.h" and leave all C files intact.
    Instead, it generates "CommonHeader.txt". Developers can manually copy its content to a local common header file in a module.

 6. Known Limitations:
    a. Tool does not handle Exit Boot Services Callback & Virtual Address Changed Event. Developers need  to handle it manually.
    b. The #include <Library/AbcLib.h> is based on library class naming convention: The header filename for "AbcLib" class are "AbcLib.h" by convention.
    c. The #include <Guid/Xyz.h>, <Protocol/Xyz.h> and <Ppi/Xyz.h> are added based on gGuidCName listed in MSA.
       If a GuidCName cannot map to a package Guid/Protocol/Ppi header file, a warning message is raised.
       If a module uses the definition in a pakcage Guid/Protocol/Ppi header file without list its associative GuidCName, the build will beak. Developer needs to       manually add the include statement.
    d. The [Depex] sections are generated from DXS files with Guid Macro translated to Guid CName by naming convention, etc.
     If tool fails to "guess" the Guid CName from Guid Macro, it will leave the GuidMacro in [Depex] section for manual resolution.
    e. When tool generates [Sources] section, the modifiers for source files are lost. (Need to add proper tool chain, etc)
    f. When tool generates [LibraryClasses] section, the recommended library instances are lost. (No impact to build)

 7. Pyton Source
    BaseTools\Source\Python\MigrationMsa2Inf

 Brief usage for Migration Tool Spd2Dec.exe:
 1. Command line format:
   Spd2Dec [options] input_filename
 2. Input File:
   A syntactically valid SPD file
 3. Output Files:
   A DEC file whose syntax confirms to DEC spec.

 4. Example:
    a. Spd2Dec -o c:\work\EdkII\Nt32Pkg\Nt32.spd c:\work\EdkII\Nt32Pkg\Nt32.dec
    b. Spd2Dec -a c:\work\EdkII\Nt32Pkg\Nt32.spd
    Example a & b are equivalent to migrate Nt32 package SPD file from EDKII to EDKII' snytax.

 6. Pyton Source
    BaseTools\Source\Python\spd2dec

 Brief usage for Migration Tool Fpd2Dsc.exe:
 1. Command line format:
   Fpd2Dsc [options] input_filename
 2. Input File:
   A syntactically valid FPD file
 3. Output Files:
   A DSC file which syntax confirms to DSC spec.
 4. Prerequisite:
    a. The workspace directory must be specified either by environment variable or -w option.

 5. Example:
    WORKSAPCE has already been set: $(WORKSPACE) = c:\work\EdkII.

    a. Fpd2Dsc -o c:\work\EdkII\Nt32Pkg\Nt32.dsc c:\work\EdkII\Nt32Pkg\Nt32.fpd
    b. Fpd2Dsc -a c:\work\EdkII\Nt32Pkg\Nt32.fpd
    Example a & b are equivalent to migrate Nt32 platform description file from EDKII to EDKII' snytax.

 6. Known Limitations:
    a. Tool does not handle Libraries Section since no related info in original FPD file. Developers need  to handle it manually in the output DSC file.
    b. If MSA file which is corresponds to module guid could not be found in currect workspace, tool will dump the module guid.
