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)

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.
|

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.
