116 Notes On Required Tools (With examples for Windows, OS X, and Linux)
117 -----------------------
118 Software Installation Order:
119 After installing the compiler tools and your Subversion client, the following
120 required tools should be installed in order:
121 Java JDK, Apache-Ant, ant-contrib, xmlbeans, saxon8
122
123 Java Development Kit:
124
125 The Java Environment Variable must be set before attempting to build.
126 For Sun JDK (see note below*):
127 set JAVA_HOME=c:\Java\jdk1.5.0_06 (Windows example)
128 export JAVA_HOME=/Library/Java/Home/ (OS X example)
129 export JAVA_HOME=/usr/lib/j2sdk1.5-sun/ (Linux example)
130 For Bea Systems:
131 set JAVA_HOME=c:\Java\jrockit-R26.0.0-jdk1.5.0_04
132
133 *When using the Sun JDK5.0
134 During installation, you should specify the install directory as C:\Java
135 instead of C:\Program Files\(or some other drive letter.) While installing
136 to this non-standard location is not required. In use, it seems to work
137 more reliably.
138 For the JDK, the install path would be C:\Java\jdk1.5.0_06
139 For the JRE, the install path would be C:\Java\jre1.5.0_06
140 Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre.
141
142 NOTE: You cannot combine the location for the JDK and the JRE, as the JRE
143 install removes most of the binaries and libraries installed by the JDK
144 install.
145
146 Java Tools:
147 The Apache-ANT requires the ANT_HOME environment variable to be set before
148 attempting to build:
149 i.e. set ANT_HOME=c:\<full path to where ant was installed>
150 export ANT_HOME=~/ExternalTools/apache-ant (OS X and Linux example)
151
152 The ant-contrib.jar file should be installed in the %ANT_HOME%\lib
153 directory.
154
155 The XMLBeans, requires the XMLBEANS_HOME environment variable to be set
156 before attempting to build:
157 i.e. set XMLBEANS_HOME=C:\<full path to where xmlbeans was installed>
158 export XMLBEANS_HOME=~/ExternalTools/xmlbeans (OS X and Linux example)
159
160 The saxon8.jar file should be copied to the %XMLBEANS_HOME%\lib directory.
161
162 The Ant and XMLBean tools are required to be in the path.
163 MS system example:
164 set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin
165 Linux/OS X bash shell example:
166 export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin
167
168 -------------------------------------------------------------------------------
169 Quick Start
170 -----------
171 Copy the target.template file in the Tools/Conf directory to target.txt, which
172 must also be in the Tools/Conf directory.
173
174 Edit the text file, target.txt, located in the Tools/Conf directory. This
175 file contains options for setting the active platform and restricting the build.
176 The restictions are used to limit the build output by specifying build target(s),
177 tagname(s) and architecture(s) to less than the full set of possible options.
178
179 The ACTIVE_PLATFORM must be set unless the current working directory contains one
180 or more FPD files. All other options need not be set, however by unsetting these
181 options (by removing the line from the file, or leaving the Value empty) will
182 result in all available build possibilites when typing build. By default EDK II
183 can build a matrix of binaries, using different target types, tool chain tags and
184 architectures. Options to target.txt file are as follows:
185
186 ACTIVE_PLATFORM = Value REQUIRED
187 Where Value is the WORKSPACE relative path and filename of a Framework Platform
188 Definition (FPD) File. Example:
189
190 ACTIVE_PLATFORM = MdePkg/MdePkg.fpd
191
192 TARGET = Value OPTIONAL
193 Where Value is a list of one or more of the following: DEBUG, RELEASE or a User
194 Defined Target type, such as PERF. Example:
195
196 TARGET = DEBUG RELEASE
197
198 TARGET_ARCH = Value OPTIONAL
199 Where Value is a list of one or more supported Architectures: IA32, X64, IPF or
200 EBC. Example:
201
202 TARGET_ARCH = IA32 X64 EBC
203
204 TOOL_CHAIN_CONF = Value OPTIONAL
205 Where Value is the Filename of an alternate tools_def.txt file created by the
206 user. The alternate tools_def.txt files must be in the Tools/Conf directory.
207 These tool definitions are scoped to the WORKSPACE (location of the EDK
208 installation) and cannot be shared between WORKSPACES. (You can copy the files
209 from one workspace to another.) Example:
210
211 TOOL_CHAIN_CONF = alfred.txt
212
213 TOOL_CHAIN_TAG = Value OPTIONAL
214 Where Value is a list of TagName entries as defined in the tools_def.txt file.
215 The TagName can be used to specify different versions of a compiler, i.e.,
216 gcc 4.0 and gcc 4.1 which will allow you to build binaries with both tool chains
217 during the same build - useful during testing of a new compiler tool chain, or
218 for changing compiler flags to check out performance with a different set of
219 flags than flags used for production. Example:
220
221 TOOL_CHAIN_TAG = GCC40 GCC41
222
223 To clear a restriction, just remove any data after the equal sign. To clear
224 the TARGET_ARCH limitation that was set above, enter:
225
226 TARGET_ARCH =
227
228 -----------
229 Copy the tools_def.template file in Tools/Conf to tools_def.txt in the same
230 directory.
231
232 Edit the tools definition file, tools_def.txt, also located in the Tools/Conf
233 directory. This file contains the names of the compiler tool chains and the
234 location of the compiler binaries. It has been pre-populated with the standard
235 location for the Microsoft tool chains and includes the standard location of
236 the Intel C Compiler for EFI Byte Code (EBC.) In addition, EDK II provides
237 support for Cygwin, Linux and OS X GCC compiler tool chains. A script has been
238 provided in the Tools/gcc directory as well as instructions in obtaining and
239 building a version of GCC that has been tested. The tools_def.txt file has
240 the GCC binary locations that are created using this script.
241
242 Both target.txt and tools_def.txt files are formatted as Property = Value,
243 which must appear on a single line. Spanning a Value entry over multiple
244 lines is not supported at this time. In the target.txt file, the Property is
245 a single, uppercase word with underscore characters. These Property names are
246 fixed by the build system. The tools_def.txt file's Property is an underscore
247 delimited coding, which supports some user defined values. The coding for
248 the Property is: TARGET_TAGNAME_ARCH_COMMAND_ATTR The Value, is either a
249 full path, full path and filename or a reserved word.
250
251 TARGET - DEBUG and RELEASE are predefined, however the user may define one or
252 more of their own TARGET types in this file.
253
254 TAGNAME - HOST, MSFT, GCC, INTC are predefined, however the user may define
255 one or more of their own TAGNAME keywords in this file.
256
257 ARCH - EDK II supports IA32, X64, IPF and EBC at this time.
258
259 COMMAND - Predefined command codes are listed in the tools_def.txt file, however
260 the user can specify additional command codes for their one, non-
261 standard tools.
262
263 ATTR - Predefined Attributes are listed in the tools_def.txt file.
264
265 NOTE: The TAGNAME: HOST is reserved and MUST be defined in order to build the
266 included Tiano tools from their C source files. These tools have been
267 built and tested using both Microsoft and GCC tool chains.
268 NOTE: The "*" symbol may be used as a wildcard character in most of these
269 fields, refer to the tools_def.txt and the "EDK II Build and Packaging
270 Architecture Specification" for more details.
271
272
273 -----------
274 Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to
275 checkout the entire EDK II source tree.
276
277 In a command window, change to the top level directory of the Edk II sources.
278 Set the WORKSPACE environment variable, e.g.:
279
280 c:\> set WORKSPACE=C:\MyWork\Edk2
281
282 To test your tool chain setup and to build the Supplied Tools, execute:
283 c:\MyWork\Edk2\> edksetup
284
285 On Unix systems you must source the edksetup.sh file to load the correct
286 settings into your shell.
287
288 . edksetup.sh # Note the dot.
289
290 (This command will be referred to as the setup command throughout the rest of
291 this document.)
292 NOTE: You should run the setup command at the start of every session.
293 This configures the environment to include the TianoTools and the
294 Java applications and libraries.
295
296 If you are confident that none of the tool tool sources have changed, and you
297 only want to set up the workspace environment you may execute:
298 c:\MyWork\Edk2\> edksetup skip
299
300 Once this is completed, you are ready to test the Build, by executing:
301 c:\MyWork\Edk2\> build
302
303 This command builds active platform specified in text file target.txt. If
304 active platform is not specified, go to sub-directory which contains FPD files and
305 type build. More information about active platform policy reference to specification
306 <<EDK II Build and Packaging Architecture Specification>>.
307
308 -------------------------
309 Individual Platform Builds
310 -------------------------
311 After running the setup command, you can build individual platforms.
312 In the command window,
313 1. Set active platform in target.txt, and type "build" in whatever directory;
314 2. or cd to the platform (FPD file) that you want to build, and just type:
315 c:\MyWork\Edk2\EdkNt32Pkg\> build
316
317 Note that active platform with the high priority to build, that means active
318 platform will be built even if exists FPD file under current directory. More
319 information about active platform policy reference to specification
320 <<EDK II Build and Packaging Architecture Specification>>.
321
322 Go to <full build path>\DEBUG\MSFT\IA32 and execute SecMain.exe
323 to run the Nt32 emulation platform under Microsoft Windows.
324
325 To exit the Nt32 emulation platform, you may type reset at the EFI Shell>
326 command prompt. Alternately, you may use the Graphical interface, Boot
327 Maintenance Manager screen's Reset System command.
328
329 ------------------------
330 Individual Module Builds
331 ------------------------
332 After running the setup command, you can build individual modules.
333 In the command window, cd to the module that you want to build, and just
334 type:
335 c:\MyWork\Edk2\MdePkg\Library\BaseLib\> build
336
337 Note active platform must be set for individual module build.
338
339 -------------------------------------------------------------------------------
340 A Word on Apache-ANT
341 --------------------
342 The Apache-ANT program is a build tool that uses XML-based project files.
343 Similar to Makefiles, these project files may contain multiple targets. Most
344 build.xml files in EDK II are auto-generated; any edits performed on the
345 build.xml files will be overwritten the next time build is executed.
346
347 Pre-defined targets in the build.xml file include:
348 all - This target builds binaries for defined architectures
349 clean - This target removes object files generated by commands
350 cleanall - This target removes all generated files and directories.
351
352 A Word on GCC tool chain
353 ------------------------
354 EDK II will not compile with a standard Linux gcc tool chain. While Linux
355 distributions are usually based on ELF, EDK II requires a version of gcc
356 that is configured to produce PE-COFF images. You will find a script in
357 edk2/Tools/gcc that will download, configure, compile, and install a gcc
358 4.X cross-compile tool chain for EDK II development. It has support for
359 the IA32 architecture. It can be built and run on Cygwin, Linux, and many
360 other POSIX compliant host operating environments. There are a few tools
361 that you will need on your host computer in order to compile the tool
362 chain. Among them are bash, gcc, gmake, curl (or wget).
363
364 -------------------------------------------------------------------------------
365
366 General Information:
367 ===============================================================
368 Mechanisms:
369 ----------
370 A brief overview:
371
372 A) Surface Area Package Description (SPD) file contains information about the
373 modules that the package contains, including the location of all MSA files, and
374 public library names and headers that might be provided by a module in the
375 package. Packages are defined by SPD files. (Found in the root of the Package
376 subdirectory (i.e. EdkNt32Pkg)) The SPD is further explained in the "EDK Build
377 and Packaging Architecture Specification" document.
378
379 B) Module Surface Area Definition (MSA) files. A description of a module's
380 surface area, with all module specific default flags and features specified.
381 Refer to the "Module Surface Area Architecture Specification" for additional
382 details. The MSA is further explained in the "EDK II Build Packaging Architecture
383 Specification" document.
384
385 C) Framework Platform Description (FPD) files. A description of a platform's
386 surface are, including a list of modules that are needed by the platform. To
387 support individual module builds, developers are not required to provide
388 information about specific flash devices, nor flash device layout. There are
389 specific sections in the FPD file that do control aspects of the build, such
390 as the Supported Architectures and Build Targets, as well as the tool flags
391 that are used to create the binary files. A valid platform file can specify
392 zero or more modules, so individual modules can be compiled within the context
393 of a platform (FPD) definition.
394
395 D) Platform Configuration Database (PCD). A platform database which contains a
396 variety of current platform settings or directives by which a driver or
397 application can interact with. The PCD is defined by the PCD_Protocol (This is
398 further explained in the "Platform Configuration Database Infrastructure
399 Description" document.
400
401 E) Library Class. A library class is a logical grouping of similar functions.
402 When developing components, the module surface area declares the class of
403 libraries that can be used by the component. The MSA and SPD files can specify
404 a recommended instance of the library that a platform integrator may select,
405 however this is only a recommendation. The PI may choose to select a different
406 library instance to be used during compilation/linking. All library type modules
407 must include header files in their distribution package, as well as their MSA
408 files. Components, on the other hand, need only provide an MSA and either source
409 or binary files when distributing packages. The Library Classes are further
410 explained in the "EDK II Build and Packaging Architecture Specification"
411 document.
412
413 =========================================================================
414 The common operations by developers of new modules are:
415 -------------------------------------------------------
416
417 1) How to manually create a new module in a package:
418 - The module source code must first be created in an appropriate directory
419 (under the package the module is to be a part of.)
420 - An MSA file must be created, spelling out all aspects of the module.
421 - The MSA must be added to the SPD for the package to include the module.
422
423 -----------------------------------------
424 2) Add/Remove module(s) to/from a package:
425
426 - Setup environment as Build
427 - Add a module to a package
428 * Generate the module SurfaceArea description file
429 * Add a new <Filename> element under <MsaFiles> into
430 <PackageDir>\<PackageName>.spd, using relative path to package
431 * Add a new <ModuleSA> entry under each <FrameworkModules> into
432 <PackageDir>\<PackageName>.fpd file if necessary.
433
434 - Remove a module from a package
435 * Comment out or remove corresponding <Filename> element under <MsaFiles>
436 from <PackageDir>\<PackageName>.spd
437 * Comment out or remove corresponding <ModuleSA> entry under each
438 <FrameworkModules> from <PackageDir>\<PackageName>.fpd if necessary.
439
440 -----------------------------------
441 3) How to manually create a package:
442 - Identify the modules that are to be members of the project.
443 - Identify the Variables and Guids required in and of the Package (including
444 consumption/production information).
445 - Create an SPD file defining these modules and calling out their MSA files.
446 - add a new <Filename> element under <PackageList> into
447 Tools\Conf\FrameworkDatabase.db, using the relative path to workspace.
448
449 --------------------------------------
450 4) Declare a new Protocol in a package:
451 - This release requires manual editing of the SPD file, adding the protocol
452 to the ProtocolDeclarations section of the file.
453 - Add the Protocol .h file to the Include\Protocol directory.
454 - Add an <Entry> to the <ProtocolDeclarations> element in the
455 <PackageName>.spd file
456 * Each line contains Protocol base name then the global variable name and
457 then the hex value of the Protocol GUID.
458
459 Example Protocol Entries (NOTE: The Guid entry is a single line in the SPD file):
460 <ProtocolDeclarations>
461 <Entry Name="Bds">
462 <C_Name>gEfiBdsArchProtocolGuid</C_Name>
463 <GuidValue>665E3FF6-46CC-11D4-9A38-0090273FC14D</GuidValue>
464 <HelpText/>
465 </Entry>
466 <Entry Name="Cpu">
467 <C_Name>gEfiCpuArchProtocolGuid</C_Name>
468 <GuidValue>26BACCB1-6F42-11D4-BCE7-0080C73C8881</GuidValue>
469 <HelpText/>
470 </Entry>
471 </ProtocolDeclarations>
472
473 ---------------------------------
474 5) Declare a new PPI in a package:
475 - This release requires manual editing of the SPD file
476 - Add the PPI .h file to the Include\Ppi directory.
477 - Add an <Entry> to the package <PpiDeclarations> element in the
478 <PackageName>.spd file
479 * Each line contains PPI base name then the global variable name and then
480 the hex value of the PPI GUID.
481
482 Example Ppi Entries (NOTE: The Guid entry is a single line in the SPD file):
483 <PpiDeclarations>
484 <Entry Name="BootInRecoveryMode">
485 <C_Name>gEfiPeiBootInRecoveryModePpiGuid</C_Name>
486 <GuidValue>17EE496A-D8E4-4B9A-94D1-CE8272300850</GuidValue>
487 <HelpText/>
488 </Entry>
489 <Entry Name="CpuIo">
490 <C_Name>gEfiPeiCpuIoPpiInServiceTableGuid</C_Name>
491 <GuidValue>E6AF1F7B-FC3F-46DA-A828-A3B457A44282</GuidValue>
492 <HelpText/>
493 </Entry>
494 </PpiDeclarations>
495
496 ----------------------------------
497 6) Declare a new GUID in a package:
498 - This release requires manual editing of the SPD file to include the new
499 Guid. This is identical to adding a ProtocolDeclaration or PpiDeclaration
500 element as described above.
501
502 ---------------------------------------
503 7) Declare a new PCD entry in a package:
504 - This release requires manual editing of the SPD file to include the new
505 PCD. New Pcd entries are added to the PcdDefinitions section of the
506 <PackageName>.spd file using the following example for the format:

540 Notes:
541 ------
542 The EDK II represents significant changes in the structure of the EDK.
543 Therefore it is very difficult to isolate all of the changes of this version of
544 the EDK with the previous (EDK 1.0) version.
545
546 Of particular note:
547
548 1) EDK II contains new hardware feature support for the ICH SMBUS Libraries.
549 These libraries are provided to make Memory Reference Code (MRC) development
550 easier.
551 2) The MDE Libraries - The MDE libraries represent significant changes in source
552 (with only limited changes in functionality.) These new libraries conform
553 to the "MDE Library Specification".
554 3) The Fat Binary and the EDK Shell Binary Packages are functionally identical
555 to the EDK 1.0 version.
556 4) The EDK tools directory has been expanded to include more tools and more
557 tool functionality.
558 5) The EDK NT32 section has been ported to the new build process, but
559 functionally remains the same as the EDK 1.0 version.
560 6) The Application "HelloWorld" has been ported to EDK II as well.
