| -------------------------------------------------------------------- | |
| Notes On Required Tools (With examples for Windows, OS X, and Linux*) | |
| -------------------------------------------------------------------- | |
| Software Installation Order: | |
| After installing the compiler tools and your Subversion client, install the | |
| following required tools in this order: | |
| 1. Java JDK | |
| 2. Apache-Ant | |
| 3. ant-contrib | |
| 4. xmlbeans | |
| 5. saxon8 | |
| Java Development Kit: | |
| The Java Environment Variable must be set before attempting to build. | |
| For Sun JDK (see note below): | |
| set JAVA_HOME=c:\Java\jdk1.5.0_06 (Windows example) | |
| export JAVA_HOME=/Library/Java/Home/ (OS X example) | |
| export JAVA_HOME=/usr/lib/j2sdk1.5-sun/ (Linux example) | |
| For Bea Systems: | |
| set JAVA_HOME=c:\Java\jrockit-R26.0.0-jdk1.5.0_04 | |
| When using the Sun JDK5.0: | |
| During installation, you should specify the install directory as C:\Java | |
| instead of C:\Program Files\(or some other drive letter.) While installing | |
| to this non-standard location is not required, in practice, it seems to work | |
| more reliably. | |
| For the JDK, the install path is C:\Java\jdk1.5.0_06 | |
| For the JRE, the install path is C:\Java\jre1.5.0_06 | |
| Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre. | |
| NOTE: You cannot combine the location for the JDK and the JRE, because the | |
| JRE install removes most of the binaries and libraries installed by the JDK | |
| install. | |
| Java Tools: | |
| The Apache-ANT requires the ANT_HOME environment variable to be set before | |
| attempting to build: | |
| set ANT_HOME=c:\<full path to where ant was installed> | |
| export ANT_HOME=~/ExternalTools/apache-ant (OS X and Linux example) | |
| The ant-contrib.jar file should be installed in the %ANT_HOME%\lib | |
| directory. | |
| XMLBeans, requires the XMLBEANS_HOME environment variable to be set | |
| before attempting to build: | |
| set XMLBEANS_HOME=C:\<full path to where xmlbeans was installed> | |
| export XMLBEANS_HOME=~/ExternalTools/xmlbeans (OS X and Linux example) | |
| Copy the saxon8.jar file to the %XMLBEANS_HOME%\lib directory. | |
| The Ant and XMLBean tools must be in the path. | |
| MS system example: | |
| set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin | |
| Linux/OS X bash shell example: | |
| export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin | |
| -------------------- | |
| A Word on Apache-ANT | |
| -------------------- | |
| The Apache-ANT program is a build tool that uses XML-based project files. | |
| Similar to Makefiles, these project files may contain multiple targets. Most | |
| build.xml files in EDK II are auto-generated; any edits performed on the | |
| build.xml files will be overwritten by the next build. | |
| Pre-defined targets in the build.xml file include: | |
| all - This target builds binaries for defined architectures. | |
| clean - This target removes object files generated by commands. | |
| cleanall - This target removes all generated files and directories. | |
| ---------------------------- | |
| A Word on the GCC Tool Chain | |
| ---------------------------- | |
| EDK II will not compile with a standard Linux gcc tool chain. While Linux | |
| distributions are usually based on ELF, EDK II requires a version of gcc | |
| that is configured to produce PE-COFF images. You will find a script in | |
| edk2/Tools/gcc that will download, configure, compile, and install a gcc | |
| 4.X cross-compile tool chain for EDK II development. This custom tool chain | |
| supports the IA-32 architecture. It can be built and run on Cygwin, Linux, and | |
| many other POSIX-compliant host operating environments. To compile the custom | |
| gcc tool chain, you need the following tools on your host computer: bash, gcc, | |
| gmake, curl (or wget). | |
| Only the MdePkg and EdkModulePkg are currently supported by gcc builds. Other | |
| builds, such as the EdkNt32Pkg, will not compile with gcc. By default, the edk2 | |
| will try to build the NT32.fpd, which is not supported by gcc. So, you need to | |
| change the Tools/Conf/target.txt. | |
| The platform to be built is identified by the Tools/Conf/target.txt file: | |
| # | |
| # PROPERTY Type Use Description | |
| # ---------------- -------- -------- ----------------------------------------------------------- | |
| # ACTIVE_PLATFORM Filename Recommended Specify the WORKSPACE relative Path and Filename | |
| # of the platform FPD file that will be used for the build | |
| # This line is required if and only if the current working | |
| # directory does not contain one or more FPD files. | |
| ACTIVE_PLATFORM = | |
| You can leave it black, as above, or set it to any .fpd file in the workspace. | |
| If you leave it blank, then you just cd to the dir that contains the .fpd that | |
| you would like to build (MdePkg/ or EdkModulePkg/) and then type build. | |
| ---------------------------- | |
| A Word on compiling on Linux | |
| ---------------------------- | |
| In order to compile on Linux, you will need to have the e2fsprogs-dev package | |
| installed. Check your distribution for the rpm, deb or other package format. | |
| This package contains the uuid library and header that are used by some of the | |
| host tools. | |
| If you are running on x86_64 Linux, then you should install a 64 bit version of | |
| the Java JDK. The version that was used was jdk-1_5_0_07-linux-amd64-rpm.bin. | |
| It may be downloaded from sun.com. | |
| ----------------------------------------- | |
| A Word on compiling under Cygwin with gcc | |
| ----------------------------------------- | |
| Cygwin is a POSIX style operating environment for Windows. It is possible to | |
| compile the EDK 2 using gcc and cygwin. Compiling under cygwin is slow, because | |
| the underlying file accesses are slow in cygwin. For this reason, we do not | |
| encourage the use of cygwin. A true unix system will be a superior choice for | |
| those wishing to compile with gcc. | |
| Make sure that you select the e2fsprogs development package when you install | |
| cygwin. It is necessary for the GenFvImage tool. | |
| ---------------------------------------- | |
| A Word on gcc for Processor Architectures | |
| ---------------------------------------- | |
| Currently gcc support is limited to IA-32 builds, generating IA-32 PE32 images. | |
| The X64 bit (Intel 64, etc.) support under the gcc compiler does not support the EFIAPI | |
| calling convention (as defined in the UEFI 2.0 specification Chapter 2), so it is not | |
| possible to build a working EFI image for an X64 environment. Since the x64 gcc does | |
| not support the EFIAPI calling convention the x64 tools do not support generating a | |
| PE32+ image. The EFIAPI calling convention is very similar to the Microsoft x64 | |
| calling convention. | |
| On Itanium® Processors the gcc compiler does not support generating a PE32+ image. | |

| Notes on Documentation | |
| ----------------------- | |
| The documents are being managed by the Subversion Source Control on | |
| Tianocore.org. The document repository is "docs" and must be checked out | |
| separately from the EDK II source tree. Refer to the checkout procedures on | |
| the Tianocore.org Web site for EDK II. | |
| The URL of the document repository is: | |
| https://edk2.tianocore.org/svn/edk2/trunk/docs | |
| ------------------------------------------------------------------------------- | |
| Quick Start | |
| ----------- | |
| (assumes Microsoft Tools and OS environment, for GCC Tools or Linux, see | |
| "Detailed Starting Instructions" below) | |
| Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to | |
| check out the entire EDK II source tree. | |
| In a command window, change to the top-level directory of the EDK II source. | |
| To test your tool chain setup and to build the supplied tools, execute: | |
| c:\MyWork\edk2\> edksetup ForceRebuild | |
| (The edksetup script is referred to as the setup command throughout the | |
| rest of this document.) | |
| NOTE: You should run the setup command at the start of every session. | |
| This configures the environment to include the TianoTools and the | |
| Java applications and libraries. | |
| You will need to set the WORKSPACE environment variable, or run the edksetup | |
| script (without any arguments), any time you want to build. | |
| Set the WORKSPACE environment variable, e.g.: | |
| c:\> set WORKSPACE=C:\MyWork\edk2 | |
| You may need to edit the text files Tools/Conf/target.txt and | |
| Tools/Conf/tools_def.txt (created by edksetup) using your favorite | |
| text editor to ensure that the paths to the tools you want to use | |
| to build EDK II binaries are correct. These files contain the default | |
| paths (as per the default installation of the tools), so a customized | |
| install may require this manual process. | |
| Once this is completed, you are ready to test the build, by executing: | |
| c:\MyWork\edk2\> build | |
| This command builds the active platform specified in text file target.txt. If | |
| the active platform is not specified target.txt, you must execute the build | |
| command from the sub-directory that contains FPD files. For more information | |
| about the active platform policy, see the EDK II Build and Packaging | |
| Architecture Specification. | |
| ------------------------------------------------------------------------------- | |
| Detailed Starting Instructions | |
| ------------------------------ | |
| Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to | |
| check out the entire EDK II source tree. | |
| In a command window, change to the top-level directory of the EDK II source. | |
| If the active compiler tool chain is GCC, you must set the | |
| environment variable, TOOL_CHAIN to "gcc" before running the | |
| edksetup script. Example: export TOOL_CHAIN=gcc | |
| To test your tool chain setup and to build the supplied tools, execute: | |
| c:\MyWork\edk2\> edksetup ForceRebuild | |
| On Linux systems, you must source the edksetup.sh file to load the correct | |
| settings into your shell. | |
| . edksetup.sh # Note the dot. | |
| If you have recently updated your code from subversion, the tools will need to | |
| be rebuilt if there were any code changes made to them. You can request that | |
| the tools get rebuilt by typing: | |
| . edksetup.sh Rebuild # Unix-like systems | |
| edksetup.bat Rebuild # Windows | |
| The edksetup script is referred to as the setup command throughout the | |
| rest of this document. | |
| NOTE: You should run the setup command at the start of every session. | |
| This configures the environment to include the TianoTools and the | |
| Java applications and libraries. | |
| Any changes to the tool source code or XML Schema documents require that | |
| you execute the following: | |
| c:\MyWork\edk2\> edksetup ForceRebuild | |
| You must set the WORKSPACE environment variable, or run the edksetup | |
| script (without any arguments), any time you want to build. | |
| Set the WORKSPACE environment variable, e.g.: | |
| c:\> set WORKSPACE=C:\MyWork\edk2 | |
| You may need to edit the text files Tools/Conf/target.txt and | |
| Tools/Conf/tools_def.txt (created by edksetup) using your favorite | |
| text editor to ensure that the paths to the tools you want to use | |
| to build EDK II binaries are correct. These files contain the default | |
| paths (as per the default installation of the tools), so a customized | |
| tool installation may require this manual process. | |
| Once this is completed, you are ready to test the build, by executing: | |
| c:\MyWork\edk2\> build | |
| This command builds the active platform specified in text file target.txt. If | |
| the active platform is not specified, go to the sub-directory that contains FPD | |
| files and execute the build command. For more information about the active | |
| platform policy, see the EDK II Build and Packaging Architecture | |
| Specification. | |
| -------------------------- | |
| Individual Platform Builds | |
| -------------------------- | |
| After running the setup command, you can build individual platforms. | |
| In the command window: | |
| Set the active platform in target.txt, and execute this command: | |
| c:\<directory>\> build | |
| or | |
| cd to the platform (FPD file) that you want to build and execute this command: | |
| c:\MyWork\edk2\EdkNt32Pkg\> build | |
| Note that the active platform specified in target.txt overrides the platform | |
| specified by any FPD file in the current directory. For more information | |
| about active platform policy, see the EDK II Build and Packaging Architecture | |
| Specification. | |
| To run the Nt32 emulation platform under Microsoft Windows, go to | |
| <full build path>\DEBUG\MSFT\IA32 and execute SecMain.exe | |
| To exit the Nt32 emulation platform, type reset at the EFI Shell> | |
| command prompt. Alternatively, from the graphical interface, select the Boot | |
| Maintenance Manager's Reset System command. | |
| NOTE: When creating a new platform, the Platform Name is restricted | |
| to a single word containing alphanumeric characters, underscore, dash, | |
| and period. The space character and other special characters are | |
| not allowed. | |
| ----------------------- | |
| Notes on Symbolic Debug | |
| ----------------------- | |
| To enable EFI Symbolic Debugging, make sure the target output is set to DEBUG | |
| in the text file Tools/Conf/target.txt and then modify the FPD <BuildOptions> | |
| <Options><Option BuildTargets="DEBUG" ToolCode="CC"> and append the following | |
| compiler options to the string: | |
| "/D EFI_GENERATE_SYM_FILE", "/D EFI_SYMBOLIC_DEBUG" | |
| (If the Option line does not contain "/D EFI_DEBUG", you must add that | |
| option as well.) | |
| ------------------------ | |
| Individual Module Builds | |
| ------------------------ | |
| After running the setup command, you can build individual modules. | |
| In the command window, cd to the module that you want to build, and | |
| execute the build command: | |
| c:\MyWork\edk2\MdePkg\Library\BaseLib\> build | |
| You must set the active platform in target.txt for individual module builds. | |
| ------------------------------------------------------------------------------- | |
| General Information: | |
| =============================================================== | |
| Mechanisms | |
| ---------- | |
| A brief overview: | |
| A) The Surface Area Package Description (SPD) file contains information about | |
| the modules that the package contains, including the location of all MSA files, | |
| and public library names and headers that might be provided by a module in the | |
| package. Packages are defined by SPD files. (Found in the root of the Package | |
| subdirectory (i.e. EdkNt32Pkg).) The SPD file is further explained in EDK II | |
| Build and Packaging Architecture Specification. | |
| B) Module Surface Area Definition (MSA) files. A description of a module's | |
| surface area, with all module specific default flags and features specified. | |
| For additional details, see the "EDK II Module Surface Area Specification" and | |
| the "EDK II Build and Packaging Architecture Specification." | |
| C) Framework Platform Description (FPD) files. A description of a platform's | |
| surface are, including a list of modules that are needed by the platform. To | |
| support individual module builds, developers are not required to provide | |
| information about specific flash devices, nor flash device layout. | |
| Specific sections in the FPD file control aspects of the build, such | |
| as the Supported Architectures and Build Targets, as well as the tool flags | |
| that are used to create the binary files. A valid platform file can specify | |
| zero or more modules, so individual modules can be compiled within the context | |
| of a platform (FPD) definition. | |
| D) Platform Configuration Database (PCD). A platform database that contains a | |
| variety of current platform settings or directives that can be accessed by a | |
| driver or application. The PCD is defined by the PCD_Protocol (This is | |
| further explained in the "EDK II Platform Configuration Database Infrastructure | |
| Description." | |
| E) Library Class. A library class is a logical grouping of similar functions. | |
| When developing components, the module surface area declares the class of | |
| libraries that can be used by the component. The MSA and SPD files can specify | |
| a recommended instance of the library that a platform integrator (PI) may | |
| select, however this is only a recommendation. The PI may choose to select a | |
| different library instance to be used during compilation and linking. All | |
| library type modules must include header files in their distribution package, | |
| as well as their MSA files. Components, on the other hand, need provide only an | |
| MSA file and either source or binary files when distributing packages. The | |
| Library Classes are further explained in the "EDK II Build and Packaging | |
| Architecture Specification." | |
| ========================================================================= | |
| The common operations by developers of new modules are: | |
| ----------------------------------------------- | |
| 1) Manually creating a new module in a package: | |
| - The module source code must first be created in an appropriate directory | |
| (under the package the module is to be a part of.) | |
| - An MSA file must be created, spelling out all aspects of the module. | |
| - The MSA must be added to the SPD for the package to include the module. | |
| ----------------------------------------------------- | |
| 2) Adding and Removing modules to and from a package: | |
| - Set up environment as Build | |
| - Adding a module to a package: | |
| - Generate the MSA file | |
| - Add a new <Filename> element under <MsaFiles> into | |
| <PackageDir>\<PackageName>.spd, using arelative path to the package | |
| - Add a new <ModuleSA> entry under each <FrameworkModules> into the | |
| <PackageDir>\<PackageName>.fpd file if necessary. | |
| - Removing a module from a package: | |
| - Comment out or remove the corresponding <Filename> element under | |
| <MsaFiles> from <PackageDir>\<PackageName>.spd | |
| - Comment out or remove the corresponding <ModuleSA> entry under each | |
| <FrameworkModules> from <PackageDir>\<PackageName>.fpd if necessary. | |
| ------------------------------- | |
| 3) Manually creating a package: | |
| - Identify the modules that are to be members of the project. | |
| - Identify the Variables and Guids required in and of the Package (including | |
| consumption and production information). | |
| - Create an SPD file defining these modules and calling out their MSA files. | |
| - Add a new <Filename> element under <PackageList> into | |
| Tools\Conf\FrameworkDatabase.db, using the relative path to the workspace. | |
| ----------------------------------------- | |
| 4) Declaring a new Protocol in a package: | |
| - This release requires manual editing of the SPD file, adding the protocol | |
| to the ProtocolDeclarations section of the file. | |
| - Add the Protocol .h file to the Include\Protocol directory. | |
| - Add an <Entry> to the <ProtocolDeclarations> element in the | |
| <PackageName>.spd file | |
| - Each line contains Protocol base name, followed by the global variable | |
| name, and the hex value of the Protocol GUID. | |
| Example Protocol Entries (NOTE: The Guid entry is a single line in the SPD | |
| file): | |
| <ProtocolDeclarations> | |
| <Entry Name="Bds"> | |
| <C_Name>gEfiBdsArchProtocolGuid</C_Name> | |
| <GuidValue>665E3FF6-46CC-11D4-9A38-0090273FC14D</GuidValue> | |
| <HelpText/> | |
| </Entry> | |
| <Entry Name="Cpu"> | |
| <C_Name>gEfiCpuArchProtocolGuid</C_Name> | |
| <GuidValue>26BACCB1-6F42-11D4-BCE7-0080C73C8881</GuidValue> | |
| <HelpText/> | |
| </Entry> | |
| </ProtocolDeclarations> | |
| ------------------------------------ | |
| 5) Declaring a new PPI in a package: | |
| - This release requires manual editing of the SPD file | |
| - Add the PPI .h file to the Include\Ppi directory. | |
| - Add an <Entry> to the package <PpiDeclarations> element in the | |
| <PackageName>.spd file | |
| - Each line contains the PPI base name, followed by the global variable | |
| name and the hex value of the PPI GUID. | |
| Example Ppi Entries (NOTE: The Guid entry is a single line in the SPD file): | |
| <PpiDeclarations> | |
| <Entry Name="BootInRecoveryMode"> | |
| <C_Name>gEfiPeiBootInRecoveryModePpiGuid</C_Name> | |
| <GuidValue>17EE496A-D8E4-4B9A-94D1-CE8272300850</GuidValue> | |
| <HelpText/> | |
| </Entry> | |
| <Entry Name="CpuIo"> | |
| <C_Name>gEfiPeiCpuIoPpiInServiceTableGuid</C_Name> | |
| <GuidValue>E6AF1F7B-FC3F-46DA-A828-A3B457A44282</GuidValue> | |
| <HelpText/> | |
| </Entry> | |
| </PpiDeclarations> | |
| ------------------------------------- | |
| 6) Declaring a new GUID in a package: | |
| - This release requires manual editing of the SPD file to include the new | |
| Guid. This is identical to adding a ProtocolDeclaration or PpiDeclaration | |
| element, as described above. | |
| ------------------------------------------ | |
| 7) Declaring a new PCD entry in a package: | |
| - This release requires manual editing of the SPD file to include the new | |
| PCD. New Pcd entries are added to the PcdDefinitions section of the | |
| <PackageName>.spd file using the following example for the format | |
| (NOTE: The hex <Token> value must be unique): | |
| <PcdDeclarations> | |
| <PcdEntry ItemType="FIXED_AT_BUILD"> | |
| <C_Name>PcdMaximumUnicodeStringLength</C_Name> | |
| <Token>0x00000001</Token> | |
| <TokenSpaceGuidCName>gEfiMdePkgTokenSpaceGuid</TokenSpaceGuidCName> | |
| <DatumType>UINT32</DatumType> | |
| <ValidUsage>FIXED_AT_BUILD</ValidUsage> | |
| <DefaultValue>1000000</DefaultValue> | |
| <HelpText>The maximum lengh for unicode string.</HelpText> | |
| </PcdEntry> | |
| </PcdDeclarations> | |
| ------------------------------ | |
| 8) Declaring a new Library Class: | |
| - This release requires manual editing of the SPD file to include the new | |
| Library Class. New Library Class entries are added to the | |

| EDK II Changes Relative to the original EDK: | |
| -------------------------------------------- | |
| The EDK II represents significant changes in the structure of the EDK. | |
| Therefore, it is very difficult to isolate all of the changes of this version of | |
| the EDK with the original EDK. | |
| Of particular note: | |
| 1) EDK II contains new hardware feature support for the ICH SMBUS Libraries. | |
| These libraries are provided to make Memory Reference Code (MRC) development | |
| easier. | |
| 2) The MDE libraries represent significant changes in source | |
| (with only limited changes in functionality.) These new libraries conform | |
| to the "EDK II Module Development Environment Library Specification. | |
| 3) The Fat Binary and the EDK Shell Binary Packages are functionally identical | |
| to the original EDK. | |
| 4) The EDK tools directory has been expanded to include more tools and more | |
| tool functionality. | |
| 5) The EDK NT32 section has been ported to the new build process, but | |
| functionally remains the same as the original EDK. | |
| 6) The Application "HelloWorld" has been ported to EDK II as well. | |
