98 Notes on Required Tools (Source Control System)
99 -----------------------------------------------
100 The EDK II is being managed by the Subversion Source Control on Tianocore.org.
101 Subversion provides speed, security, and additional features. The
102 recommended client is TortoiseSVN version 1.3.3.
103 (Available at http://tortoisesvn.tigris.org/)
105 The checkout procedures on the Tianocore.org Web site include
106 instructions for the use of Subversion Source Control.
108 The URL of the EDK II repository is:

112 --------------------------------------------------------------------
113 Notes On Required Tools (With examples for Windows, OS X, and Linux*)
114 --------------------------------------------------------------------
115 Software Installation Order:
116 After installing the compiler tools and your Subversion client, install the
117 following required tools in this order:
124 Java Development Kit:
126 The Java Environment Variable must be set before attempting to build.
127 For Sun JDK (see note below
\86):
128 set JAVA_HOME=c:\Java\jdk1.5.0_06 (Windows example)
129 export JAVA_HOME=/Library/Java/Home/ (OS X example)
130 export JAVA_HOME=/usr/lib/j2sdk1.5-sun/ (Linux example)
132 set JAVA_HOME=c:\Java\jrockit-R26.0.0-jdk1.5.0_04
134 \86 When using the Sun JDK5.0:
135 During installation, you should specify the install directory as C:\Java
136 instead of C:\Program Files\(or some other drive letter.) While installing
137 to this non-standard location is not required, in practice, it seems to work
139 For the JDK, the install path is C:\Java\jdk1.5.0_06
140 For the JRE, the install path is C:\Java\jre1.5.0_06
141 Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre.
143 NOTE: You cannot combine the location for the JDK and the JRE, because the
144 JRE install removes most of the binaries and libraries installed by the JDK
148 The Apache-ANT requires the ANT_HOME environment variable to be set before
150 set ANT_HOME=c:\<full path to where ant was installed>
151 export ANT_HOME=~/ExternalTools/apache-ant (OS X and Linux example)
153 The ant-contrib.jar file should be installed in the %ANT_HOME%\lib
156 XMLBeans, requires the XMLBEANS_HOME environment variable to be set
157 before attempting to build:
158 set XMLBEANS_HOME=C:\<full path to where xmlbeans was installed>
159 export XMLBEANS_HOME=~/ExternalTools/xmlbeans (OS X and Linux example)
161 Copy the saxon8.jar file to the %XMLBEANS_HOME%\lib directory.
163 The Ant and XMLBean tools must be in the path.
165 set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin
166 Linux/OS X bash shell example:
167 export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin
172 The Apache-ANT program is a build tool that uses XML-based project files.
173 Similar to Makefiles, these project files may contain multiple targets. Most
174 build.xml files in EDK II are auto-generated; any edits performed on the
175 build.xml files will be overwritten by the next build.
177 Pre-defined targets in the build.xml file include:
178 all - This target builds binaries for defined architectures.
179 clean - This target removes object files generated by commands.
180 cleanall - This target removes all generated files and directories.
182 ----------------------------
183 A Word on the GCC Tool Chain
184 ----------------------------
185 EDK II will not compile with a standard Linux gcc tool chain. While Linux
186 distributions are usually based on ELF, EDK II requires a version of gcc
187 that is configured to produce PE-COFF images. You will find a script in
188 edk2/Tools/gcc that will download, configure, compile, and install a gcc
189 4.X cross-compile tool chain for EDK II development. This custom tool chain
190 supports the IA-32 architecture. It can be built and run on Cygwin, Linux, and
191 many other POSIX-compliant host operating environments. To compile the custom
192 gcc tool chain, you need the following tools on your host computer: bash, gcc,
193 gmake, curl (or wget).
196 -----------------------
197 Notes on Documentation
198 -----------------------
199 The documents are being managed by the Subversion Source Control on
200 Tianocore.org. The document repository is "docs" and must be checked out
201 separately from the EDK II source tree. Refer to the checkout procedures on
202 the Tianocore.org Web site for EDK II.
204 The URL of the document repository is:
205 https://edk2.tianocore.org/svn/edk2/trunk/docs
208 -------------------------------------------------------------------------------
211 (assumes Microsoft Tools and OS environment, for GCC Tools or Linux, see
212 "Detailed Starting Instructions" below)
214 Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to
215 check out the entire EDK II source tree.
217 In a command window, change to the top-level directory of the EDK II source.
219 To test your tool chain setup and to build the supplied tools, execute:
220 c:\MyWork\edkii\> edksetup ForceBuild
222 (The edksetup script is referred to as the setup command throughout the
223 rest of this document.)
224 NOTE: You should run the setup command at the start of every session.
225 This configures the environment to include the TianoTools and the
226 Java applications and libraries.
228 You will need to set the WORKSPACE environment variable, or run the edksetup
229 script (without any arguments), any time you want to build.
231 Set the WORKSPACE environment variable, e.g.:
233 c:\> set WORKSPACE=C:\MyWork\edkii
235 You may need to edit the text files Tools/Conf/target.txt and
236 Tools/Conf/tools_def.txt (created by edksetup) using your favorite
237 text editor to ensure that the paths to the tools you want to use
238 to build EDK II binaries are correct. These files contain the default
239 paths (as per the default installation of the tools), so a customized
240 install may require this manual process.
242 Once this is completed, you are ready to test the build, by executing:
243 c:\MyWork\edkii\> build
245 This command builds the active platform specified in text file target.txt. If
246 the active platform is not specified target.txt, you must execute the build
247 command from the sub-directory that contains FPD files. For more information
248 about the active platform policy, see the
\93EDK II Build and Packaging
249 Architecture Specification.
\94
251 -------------------------------------------------------------------------------
252 Detailed Starting Instructions
253 ------------------------------
255 Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to
256 check out the entire EDK II source tree.
258 In a command window, change to the top-level directory of the EDK II source.
260 If the active compiler tool chain is GCC, you must set the
261 environment variable, TOOL_CHAIN to "gcc" before running the
262 edksetup script. Example: export TOOL_CHAIN=gcc
264 To test your tool chain setup and to build the supplied tools, execute:
265 c:\MyWork\edkii\> edksetup ForceBuild
267 On Linux systems, you must source the edksetup.sh file to load the correct
268 settings into your shell.
270 . edksetup.sh # Note the dot.
272 The edksetup script is referred to as the setup command throughout the
273 rest of this document.
274 NOTE: You should run the setup command at the start of every session.
275 This configures the environment to include the TianoTools and the
276 Java applications and libraries.
278 Any changes to the tool source code or XML Schema documents require that
279 you execute the following:
280 c:\MyWork\edkii\> edksetup ForceBuild
282 You must set the WORKSPACE environment variable, or run the edksetup
283 script (without any arguments), any time you want to build.
285 Set the WORKSPACE environment variable, e.g.:
287 c:\> set WORKSPACE=C:\MyWork\edkii
289 You may need to edit the text files Tools/Conf/target.txt and
290 Tools/Conf/tools_def.txt (created by edksetup) using your favorite
291 text editor to ensure that the paths to the tools you want to use
292 to build EDK II binaries are correct. These files contain the default
293 paths (as per the default installation of the tools), so a customized
294 tool installation may require this manual process.
296 Once this is completed, you are ready to test the build, by executing:
297 c:\MyWork\edkii\> build
299 This command builds the active platform specified in text file target.txt. If
300 the active platform is not specified, go to the sub-directory that contains FPD
301 files and execute the build command. For more information about the active
302 platform policy, see the
\93EDK II Build and Packaging Architecture
305 --------------------------
306 Individual Platform Builds
307 --------------------------
308 After running the setup command, you can build individual platforms.
309 In the command window:
310 Set the active platform in target.txt, and execute this command:
311 c:\<directory>\> build
313 cd to the platform (FPD file) that you want to build and execute this command:
314 c:\MyWork\edkii\EdkNt32Pkg\> build
316 Note that the active platform specified in target.txt overrides the platform
317 specified by any FPD file in the current directory. For more information
318 about active platform policy, see the
\93EDK II Build and Packaging Architecture
321 To run the Nt32 emulation platform under Microsoft Windows, go to
322 <full build path>\DEBUG\MSFT\IA32 and execute SecMain.exe
324 To exit the Nt32 emulation platform, type
\93reset
\94 at the EFI Shell>
325 command prompt. Alternatively, from the graphical interface, select the Boot
326 Maintenance Manager's
\93Reset System
\94 command.
328 NOTE: When creating a new platform, the Platform Name should be restricted
329 to a single word, containing alphanumeric characters, with special characters,
330 underscore, dash and the period character also allowed. Space characters and
331 other special characters are not allowed.
333 -----------------------
334 Notes on Symbolic Debug
335 -----------------------
336 To enable EFI Symbolic Debugging, make sure the target output is set to DEBUG
337 in the text file Tools/Conf/target.txt and then modify the FPD <BuildOptions>
338 <Options><Option BuildTargets="DEBUG" ToolCode="CC"> and append the following
339 compiler options to the string:
340 "/D EFI_GENERATE_SYM_FILE", "/D EFI_SYMBOLIC_DEBUG"
342 (If the Option line does not contain "/D EFI_DEBUG", you must add that
345 ------------------------
346 Individual Module Builds
347 ------------------------
348 After running the setup command, you can build individual modules.
349 In the command window, cd to the module that you want to build, and
350 execute the build command:
351 c:\MyWork\edkii\MdePkg\Library\BaseLib\> build
353 You must set the active platform in target.txt for individual module builds.
355 -------------------------------------------------------------------------------
358 ===============================================================
363 A) The Surface Area Package Description (SPD) file contains information about
364 the modules that the package contains, including the location of all MSA files,
365 and public library names and headers that might be provided by a module in the
366 package. Packages are defined by SPD files. (Found in the root of the Package
367 subdirectory (i.e. EdkNt32Pkg).) The SPD file is further explained in
\93EDK II
368 Build and Packaging Architecture Specification.
\94
370 B) Module Surface Area Definition (MSA) files. A description of a module's
371 surface area, with all module specific default flags and features specified.
372 For additional details, see the "EDK II Module Surface Area Specification" and
373 the "EDK II Build and Packaging Architecture Specification."
375 C) Framework Platform Description (FPD) files. A description of a platform's
376 surface are, including a list of modules that are needed by the platform. To
377 support individual module builds, developers are not required to provide
378 information about specific flash devices, nor flash device layout.
379 Specific sections in the FPD file control aspects of the build, such
380 as the Supported Architectures and Build Targets, as well as the tool flags
381 that are used to create the binary files. A valid platform file can specify
382 zero or more modules, so individual modules can be compiled within the context
383 of a platform (FPD) definition.
385 D) Platform Configuration Database (PCD). A platform database that contains a
386 variety of current platform settings or directives that can be accessed by a
387 driver or application. The PCD is defined by the PCD_Protocol (This is
388 further explained in the "EDK II Platform Configuration Database Infrastructure
391 E) Library Class. A library class is a logical grouping of similar functions.
392 When developing components, the module surface area declares the class of
393 libraries that can be used by the component. The MSA and SPD files can specify
394 a recommended instance of the library that a platform integrator (PI) may
395 select, however this is only a recommendation. The PI may choose to select a
396 different library instance to be used during compilation and linking. All
397 library type modules must include header files in their distribution package,
398 as well as their MSA files. Components, on the other hand, need provide only an
399 MSA file and either source or binary files when distributing packages. The
400 Library Classes are further explained in the "EDK II Build and Packaging
401 Architecture Specification."
403 =========================================================================
404 The common operations by developers of new modules are:
405 -----------------------------------------------
406 1) Manually creating a new module in a package:
407 - The module source code must first be created in an appropriate directory
408 (under the package the module is to be a part of.)
409 - An MSA file must be created, spelling out all aspects of the module.
410 - The MSA must be added to the SPD for the package to include the module.
412 -----------------------------------------------------
413 2) Adding and Removing modules to and from a package:
415 - Set up environment as Build
416 - Adding a module to a package:
417 - Generate the MSA file
418 - Add a new <Filename> element under <MsaFiles> into
419 <PackageDir>\<PackageName>.spd, using arelative path to the package
420 - Add a new <ModuleSA> entry under each <FrameworkModules> into the
421 <PackageDir>\<PackageName>.fpd file if necessary.
423 - Removing a module from a package:
424 - Comment out or remove the corresponding <Filename> element under
425 <MsaFiles> from <PackageDir>\<PackageName>.spd
426 - Comment out or remove the corresponding <ModuleSA> entry under each
427 <FrameworkModules> from <PackageDir>\<PackageName>.fpd if necessary.
429 -------------------------------
430 3) Manually creating a package:
431 - Identify the modules that are to be members of the project.
432 - Identify the Variables and Guids required in and of the Package (including
433 consumption and production information).
434 - Create an SPD file defining these modules and calling out their MSA files.
435 - Add a new <Filename> element under <PackageList> into
436 Tools\Conf\FrameworkDatabase.db, using the relative path to the workspace.
438 -----------------------------------------
439 4) Declaring a new Protocol in a package:
440 - This release requires manual editing of the SPD file, adding the protocol
441 to the ProtocolDeclarations section of the file.
442 - Add the Protocol .h file to the Include\Protocol directory.
443 - Add an <Entry> to the <ProtocolDeclarations> element in the
444 <PackageName>.spd file
445 - Each line contains Protocol base name, followed by the global variable
446 name, and the hex value of the Protocol GUID.
448 Example Protocol Entries (NOTE: The Guid entry is a single line in the SPD
450 <ProtocolDeclarations>
452 <C_Name>gEfiBdsArchProtocolGuid</C_Name>
453 <GuidValue>665E3FF6-46CC-11D4-9A38-0090273FC14D</GuidValue>
457 <C_Name>gEfiCpuArchProtocolGuid</C_Name>
458 <GuidValue>26BACCB1-6F42-11D4-BCE7-0080C73C8881</GuidValue>
461 </ProtocolDeclarations>
463 ------------------------------------
464 5) Declaring a new PPI in a package:
465 - This release requires manual editing of the SPD file
466 - Add the PPI .h file to the Include\Ppi directory.
467 - Add an <Entry> to the package <PpiDeclarations> element in the
468 <PackageName>.spd file
469 - Each line contains the PPI base name, followed by the global variable
470 name and the hex value of the PPI GUID.
472 Example Ppi Entries (NOTE: The Guid entry is a single line in the SPD file):
474 <Entry Name="BootInRecoveryMode">
475 <C_Name>gEfiPeiBootInRecoveryModePpiGuid</C_Name>
476 <GuidValue>17EE496A-D8E4-4B9A-94D1-CE8272300850</GuidValue>
480 <C_Name>gEfiPeiCpuIoPpiInServiceTableGuid</C_Name>
481 <GuidValue>E6AF1F7B-FC3F-46DA-A828-A3B457A44282</GuidValue>
486 -------------------------------------
487 6) Declaring a new GUID in a package:
488 - This release requires manual editing of the SPD file to include the new
489 Guid. This is identical to adding a ProtocolDeclaration or PpiDeclaration
490 element, as described above.
492 ------------------------------------------
493 7) Declaring a new PCD entry in a package:
494 - This release requires manual editing of the SPD file to include the new
495 PCD. New Pcd entries are added to the PcdDefinitions section of the
496 <PackageName>.spd file using the following example for the format
497 (NOTE: The hex <Token> value must be unique):
500 <PcdEntry ItemType="FIXED_AT_BUILD">
501 <C_Name>PcdMaximumUnicodeStringLength</C_Name>
502 <Token>0x00000001</Token>
503 <TokenSpaceGuidCName>gEfiMdePkgTokenSpaceGuid</TokenSpaceGuidCName>
504 <DatumType>UINT32</DatumType>
505 <ValidUsage>FIXED_AT_BUILD</ValidUsage>
506 <DefaultValue>1000000</DefaultValue>
507 <HelpText>The maximum lengh for unicode string.</HelpText>
511 ------------------------------
512 8) Declaring a new Library Class:
513 - This release requires manual editing of the SPD file to include the new
514 Library Class. New Library Class entries are added to the
515 LibraryClassDeclarations section of the <PackageName>.spd file using
516 the following example for the format:
518 <LibraryClassDeclarations>
519 <LibraryClass Name="BaseLib">
520 <IncludeHeader>Include/Library/BaseLib.h</IncludeHeader>
523 <LibraryClass Name="BaseMemoryLib">
524 <IncludeHeader>Include/Library/BaseMemoryLib.h</IncludeHeader>
527 </LibraryClassDeclarations>
529 =======================================================
530 EDK II Changes Relative to the original EDK:
531 --------------------------------------------
532 The EDK II represents significant changes in the structure of the EDK.
533 Therefore, it is very difficult to isolate all of the changes of this version of
534 the EDK with the original EDK.
538 1) EDK II contains new hardware feature support for the ICH SMBUS Libraries.
539 These libraries are provided to make Memory Reference Code (MRC) development
541 2) The MDE libraries represent significant changes in source
542 (with only limited changes in functionality.) These new libraries conform
543 to the "EDK II Module Development Environment Library Specification.
\94
544 3) The Fat Binary and the EDK Shell Binary Packages are functionally identical
546 4) The EDK tools directory has been expanded to include more tools and more
548 5) The EDK NT32 section has been ported to the new build process, but
549 functionally remains the same as the original EDK.
550 6) The Application "HelloWorld" has been ported to EDK II as well.
