6132429e 116Notes On Required Tools (With examples for Windows, OS X, and Linux) \r
aa0bf4f4 117-----------------------\r
118Software Installation Order:\r
119 After installing the compiler tools and your Subversion client, the following\r
120 required tools should be installed in order: \r
121 Java JDK, Apache-Ant, ant-contrib, xmlbeans, saxon8\r
122\r
123Java Development Kit:\r
124 \r
125 The Java Environment Variable must be set before attempting to build.\r
6132429e 126 For Sun JDK (see note below*):\r
127 set JAVA_HOME=c:\Java\jdk1.5.0_06 (Windows example)\r
128 export JAVA_HOME=/Library/Java/Home/ (OS X example)\r
129 export JAVA_HOME=/usr/lib/j2sdk1.5-sun/ (Linux example)\r
130 For Bea Systems:\r
782eb168 131 set JAVA_HOME=c:\Java\jrockit-R26.0.0-jdk1.5.0_04\r
aa0bf4f4 132 \r
133 *When using the Sun JDK5.0\r
134 During installation, you should specify the install directory as C:\Java\r
135 instead of C:\Program Files\(or some other drive letter.) While installing\r
136 to this non-standard location is not required. In use, it seems to work \r
137 more reliably. \r
138 For the JDK, the install path would be C:\Java\jdk1.5.0_06\r
139 For the JRE, the install path would be C:\Java\jre1.5.0_06\r
140 Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre.\r
01d2ed5e 141\r
aa0bf4f4 142 NOTE: You cannot combine the location for the JDK and the JRE, as the JRE\r
143 install removes most of the binaries and libraries installed by the JDK\r
144 install.\r
145\r
146Java Tools:\r
147 The Apache-ANT requires the ANT_HOME environment variable to be set before\r
148 attempting to build:\r
01d2ed5e 149 i.e. set ANT_HOME=c:\<full path to where ant was installed>\r
6132429e 150 export ANT_HOME=~/ExternalTools/apache-ant (OS X and Linux example)\r
aa0bf4f4 151\r
152 The ant-contrib.jar file should be installed in the %ANT_HOME%\lib \r
153 directory.\r
154\r
155 The XMLBeans, requires the XMLBEANS_HOME environment variable to be set\r
156 before attempting to build:\r
782eb168 157 i.e. set XMLBEANS_HOME=C:\<full path to where xmlbeans was installed>\r
6132429e 158 export XMLBEANS_HOME=~/ExternalTools/xmlbeans (OS X and Linux example)\r
aa0bf4f4 159\r
160 The saxon8.jar file should be copied to the %XMLBEANS_HOME%\lib directory.\r
161\r
162 The Ant and XMLBean tools are required to be in the path.\r
163 MS system example:\r
164 set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin\r
165 Linux/OS X bash shell example:\r
166 export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin\r
167 \r
168-------------------------------------------------------------------------------\r
169Quick Start\r
170-----------\r
3c367f9d 171For editing text files under Windows, use the Wordpad application. Notepad\r
172does not handle UNIX style newline characters properly.\r
173\r
a032fb4d 174Copy the target.template file in the Tools/Conf directory to target.txt, which\r
175must also be in the Tools/Conf directory.\r
176\r
e3f236c8 177Edit the text file, target.txt, located in the Tools/Conf directory. This \r
a032fb4d 178file contains options for setting the active platform and restricting the build. \r
179The restictions are used to limit the build output by specifying build target(s), \r
180tagname(s) and architecture(s) to less than the full set of possible options. \r
181\r
73da4c04 182The ACTIVE_PLATFORM must be set unless the current working directory contains one\r
183or more FPD files. All other options need not be set, however by unsetting these\r
184options (by removing the line from the file, or leaving the Value empty) will \r
185result in all available build possibilites when typing build. By default EDK II\r
186can build a matrix of binaries, using different target types, tool chain tags and \r
187architectures. Options to target.txt file are as follows:\r
a032fb4d 188\r
3c367f9d 189ACTIVE_PLATFORM = Value RECOMMENDED\r
a032fb4d 190 Where Value is the WORKSPACE relative path and filename of a Framework Platform \r
191 Definition (FPD) File. Example:\r
192\r
193ACTIVE_PLATFORM = MdePkg/MdePkg.fpd\r
194\r
195TARGET = Value OPTIONAL\r
196 Where Value is a list of one or more of the following: DEBUG, RELEASE or a User\r
197 Defined Target type, such as PERF. Example: \r
198\r
199TARGET = DEBUG RELEASE\r
200\r
201TARGET_ARCH = Value OPTIONAL\r
202 Where Value is a list of one or more supported Architectures: IA32, X64, IPF or\r
203 EBC. Example: \r
204\r
205TARGET_ARCH = IA32 X64 EBC\r
206\r
207TOOL_CHAIN_CONF = Value OPTIONAL\r
208 Where Value is the Filename of an alternate tools_def.txt file created by the\r
209 user. The alternate tools_def.txt files must be in the Tools/Conf directory.\r
210 These tool definitions are scoped to the WORKSPACE (location of the EDK \r
211 installation) and cannot be shared between WORKSPACES. (You can copy the files\r
212 from one workspace to another.) Example: \r
213\r
214TOOL_CHAIN_CONF = alfred.txt\r
215\r
216TOOL_CHAIN_TAG = Value OPTIONAL\r
217 Where Value is a list of TagName entries as defined in the tools_def.txt file.\r
218 The TagName can be used to specify different versions of a compiler, i.e., \r
219 gcc 4.0 and gcc 4.1 which will allow you to build binaries with both tool chains \r
220 during the same build - useful during testing of a new compiler tool chain, or \r
221 for changing compiler flags to check out performance with a different set of \r
222 flags than flags used for production. Example:\r
223\r
224TOOL_CHAIN_TAG = GCC40 GCC41\r
225\r
226To clear a restriction, just remove any data after the equal sign. To clear\r
227the TARGET_ARCH limitation that was set above, enter: \r
228\r
229TARGET_ARCH =\r
230\r
231-----------\r
232Copy the tools_def.template file in Tools/Conf to tools_def.txt in the same\r
233directory.\r
e3f236c8 234\r
235Edit the tools definition file, tools_def.txt, also located in the Tools/Conf \r
236directory. This file contains the names of the compiler tool chains and the \r
237location of the compiler binaries. It has been pre-populated with the standard \r
238location for the Microsoft tool chains and includes the standard location of \r
a032fb4d 239the Intel C Compiler for EFI Byte Code (EBC.) In addition, EDK II provides\r
240support for Cygwin, Linux and OS X GCC compiler tool chains. A script has been\r
241provided in the Tools/gcc directory as well as instructions in obtaining and\r
242building a version of GCC that has been tested. The tools_def.txt file has\r
243the GCC binary locations that are created using this script.\r
244\r
245Both target.txt and tools_def.txt files are formatted as Property = Value, \r
246which must appear on a single line. Spanning a Value entry over multiple\r
247lines is not supported at this time. In the target.txt file, the Property is\r
248a single, uppercase word with underscore characters. These Property names are\r
249fixed by the build system. The tools_def.txt file's Property is an underscore\r
250delimited coding, which supports some user defined values. The coding for\r
251the Property is: TARGET_TAGNAME_ARCH_COMMAND_ATTR The Value, is either a \r
252full path, full path and filename or a reserved word.\r
253\r
254TARGET - DEBUG and RELEASE are predefined, however the user may define one or\r
255 more of their own TARGET types in this file.\r
256\r
257TAGNAME - HOST, MSFT, GCC, INTC are predefined, however the user may define \r
258 one or more of their own TAGNAME keywords in this file.\r
259\r
260ARCH - EDK II supports IA32, X64, IPF and EBC at this time.\r
261\r
262COMMAND - Predefined command codes are listed in the tools_def.txt file, however\r
263 the user can specify additional command codes for their one, non-\r
264 standard tools.\r
265\r
266ATTR - Predefined Attributes are listed in the tools_def.txt file.\r
267\r
268NOTE: The TAGNAME: HOST is reserved and MUST be defined in order to build the\r
269 included Tiano tools from their C source files. These tools have been\r
270 built and tested using both Microsoft and GCC tool chains.\r
271NOTE: The "*" symbol may be used as a wildcard character in most of these\r
272 fields, refer to the tools_def.txt and the "EDK II Build and Packaging\r
273 Architecture Specification" for more details.\r
274\r
275\r
276-----------\r
aa0bf4f4 277Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to\r
13421853 278checkout the entire EDK II source tree.\r
aa0bf4f4 279\r
e3f236c8 280In a command window, change to the top level directory of the Edk II sources.\r
aa0bf4f4 281 Set the WORKSPACE environment variable, e.g.:\r
282\r
a032fb4d 283 c:\> set WORKSPACE=C:\MyWork\Edk2\r
aa0bf4f4 284\r
285To test your tool chain setup and to build the Supplied Tools, execute:\r
a032fb4d 286 c:\MyWork\Edk2\> edksetup\r
aa0bf4f4 287\r
6132429e 288On Unix systems you must source the edksetup.sh file to load the correct\r
289settings into your shell.\r
290\r
291 . edksetup.sh # Note the dot.\r
292\r
aa0bf4f4 293(This command will be referred to as the setup command throughout the rest of\r
294this document.)\r
295 NOTE: You should run the setup command at the start of every session.\r
296 This configures the environment to include the TianoTools and the\r
297 Java applications and libraries.\r
298\r
a032fb4d 299If you are confident that none of the tool tool sources have changed, and you\r
300only want to set up the workspace environment you may execute:\r
301 c:\MyWork\Edk2\> edksetup skip\r
302\r
aa0bf4f4 303Once this is completed, you are ready to test the Build, by executing:\r
a032fb4d 304 c:\MyWork\Edk2\> build\r
aa0bf4f4 305\r
e3f236c8 306This command builds active platform specified in text file target.txt. If \r
307active platform is not specified, go to sub-directory which contains FPD files and\r
308type build. More information about active platform policy reference to specification\r
309<<EDK II Build and Packaging Architecture Specification>>.\r
90f7b6a8 310\r
aa0bf4f4 311-------------------------\r
e3f236c8 312Individual Platform Builds\r
aa0bf4f4 313-------------------------\r
e3f236c8 314After running the setup command, you can build individual platforms.\r
315 In the command window, \r
316 1. Set active platform in target.txt, and type "build" in whatever directory;\r
317 2. or cd to the platform (FPD file) that you want to build, and just type:\r
a032fb4d 318 c:\MyWork\Edk2\EdkNt32Pkg\> build\r
e3f236c8 319\r
320 Note that active platform with the high priority to build, that means active \r
321 platform will be built even if exists FPD file under current directory. More \r
322 information about active platform policy reference to specification\r
323 <<EDK II Build and Packaging Architecture Specification>>. \r
aa0bf4f4 324\r
a032fb4d 325Go to <full build path>\DEBUG\MSFT\IA32 and execute SecMain.exe\r
e3f236c8 326to run the Nt32 emulation platform under Microsoft Windows.\r
aa0bf4f4 327\r
03fed93e 328To exit the Nt32 emulation platform, you may type reset at the EFI Shell>\r
329command prompt. Alternately, you may use the Graphical interface, Boot\r
330Maintenance Manager screen's Reset System command.\r
331\r
aa0bf4f4 332------------------------\r
333Individual Module Builds\r
334------------------------\r
335After running the setup command, you can build individual modules.\r
336 In the command window, cd to the module that you want to build, and just\r
337 type:\r
a032fb4d 338 c:\MyWork\Edk2\MdePkg\Library\BaseLib\> build\r
e3f236c8 339\r
340 Note active platform must be set for individual module build. \r
aa0bf4f4 341\r
342-------------------------------------------------------------------------------\r
343A Word on Apache-ANT\r
344--------------------\r
345The Apache-ANT program is a build tool that uses XML-based project files.\r
346Similar to Makefiles, these project files may contain multiple targets. Most\r
a032fb4d 347build.xml files in EDK II are auto-generated; any edits performed on the\r
348build.xml files will be overwritten the next time build is executed.\r
aa0bf4f4 349\r
a032fb4d 350Pre-defined targets in the build.xml file include:\r
aa0bf4f4 351 all - This target builds binaries for defined architectures\r
352 clean - This target removes object files generated by commands\r
353 cleanall - This target removes all generated files and directories.\r
354\r
355A Word on GCC tool chain\r
356------------------------\r
a032fb4d 357EDK II will not compile with a standard Linux gcc tool chain. While Linux\r
358distributions are usually based on ELF, EDK II requires a version of gcc \r
359that is configured to produce PE-COFF images. You will find a script in \r
360edk2/Tools/gcc that will download, configure, compile, and install a gcc \r
3614.X cross-compile tool chain for EDK II development. It has support for \r
362the IA32 architecture. It can be built and run on Cygwin, Linux, and many \r
363other POSIX compliant host operating environments. There are a few tools\r
364that you will need on your host computer in order to compile the tool \r
365chain. Among them are bash, gcc, gmake, curl (or wget).\r

369General Information:\r
370=============================================================== \r
371Mechanisms:\r
372----------\r
8fb9e6b8 373A brief overview:\r
aa0bf4f4 374\r
375A) Surface Area Package Description (SPD) file contains information about the\r
376modules that the package contains, including the location of all MSA files, and\r
377public library names and headers that might be provided by a module in the\r
378package. Packages are defined by SPD files. (Found in the root of the Package\r
a032fb4d 379subdirectory (i.e. EdkNt32Pkg)) The SPD is further explained in the "EDK Build \r
380and Packaging Architecture Specification" document.\r
aa0bf4f4 381 \r
382B) Module Surface Area Definition (MSA) files. A description of a module's \r
383surface area, with all module specific default flags and features specified.\r
384Refer to the "Module Surface Area Architecture Specification" for additional\r
a032fb4d 385details. The MSA is further explained in the "EDK II Build Packaging Architecture \r
386Specification" document.\r
387\r
388C) Framework Platform Description (FPD) files. A description of a platform's\r
389surface are, including a list of modules that are needed by the platform. To\r
390support individual module builds, developers are not required to provide\r
391information about specific flash devices, nor flash device layout. There are\r
392specific sections in the FPD file that do control aspects of the build, such \r
393as the Supported Architectures and Build Targets, as well as the tool flags \r
394that are used to create the binary files. A valid platform file can specify \r
395zero or more modules, so individual modules can be compiled within the context\r
396of a platform (FPD) definition.\r
397\r
398D) Platform Configuration Database (PCD). A platform database which contains a\r
aa0bf4f4 399variety of current platform settings or directives by which a driver or\r
400application can interact with. The PCD is defined by the PCD_Protocol (This is\r
401further explained in the "Platform Configuration Database Infrastructure \r
402Description" document.\r
403\r
a032fb4d 404E) Library Class. A library class is a logical grouping of similar functions.\r
aa0bf4f4 405When developing components, the module surface area declares the class of\r
a032fb4d 406libraries that can be used by the component. The MSA and SPD files can specify\r
407a recommended instance of the library that a platform integrator may select,\r
408however this is only a recommendation. The PI may choose to select a different\r
409library instance to be used during compilation/linking. All library type modules \r
410must include header files in their distribution package, as well as their MSA\r
411files. Components, on the other hand, need only provide an MSA and either source\r
412or binary files when distributing packages. The Library Classes are further \r
413explained in the "EDK II Build and Packaging Architecture Specification" \r
414document.\r

417The common operations by developers of new modules are:\r
418-------------------------------------------------------\r
419\r
4201) How to manually create a new module in a package:\r
421 - The module source code must first be created in an appropriate directory\r
422 (under the package the module is to be a part of.) \r
423 - An MSA file must be created, spelling out all aspects of the module.\r
424 - The MSA must be added to the SPD for the package to include the module.\r
425\r
426-----------------------------------------\r
4272) Add/Remove module(s) to/from a package:\r
428\r
429 - Setup environment as Build\r
430 - Add a module to a package\r
e3f236c8 431 * Generate the module SurfaceArea description file\r
432 * Add a new <Filename> element under <MsaFiles> into\r
aa0bf4f4 433 <PackageDir>\<PackageName>.spd, using relative path to package\r
e3f236c8 434 * Add a new <ModuleSA> entry under each <FrameworkModules> into\r
435 <PackageDir>\<PackageName>.fpd file if necessary. \r
aa0bf4f4 436\r
437 - Remove a module from a package\r
e3f236c8 438 * Comment out or remove corresponding <Filename> element under <MsaFiles>\r
aa0bf4f4 439 from <PackageDir>\<PackageName>.spd\r
440 * Comment out or remove corresponding <ModuleSA> entry under each\r
e3f236c8 441 <FrameworkModules> from <PackageDir>\<PackageName>.fpd if necessary. \r
aa0bf4f4 442\r
443-----------------------------------\r
4443) How to manually create a package:\r
445 - Identify the modules that are to be members of the project.\r
446 - Identify the Variables and Guids required in and of the Package (including\r
447 consumption/production information).\r
448 - Create an SPD file defining these modules and calling out their MSA files.\r
e3f236c8 449 - add a new <Filename> element under <PackageList> into \r
450 Tools\Conf\FrameworkDatabase.db, using the relative path to workspace. \r
aa0bf4f4 451\r
452--------------------------------------\r
4534) Declare a new Protocol in a package: \r
454 - This release requires manual editing of the SPD file, adding the protocol\r
455 to the ProtocolDeclarations section of the file. \r
456 - Add the Protocol .h file to the Include\Protocol directory.\r
64fcaead 457 - Add an <Entry> to the <ProtocolDeclarations> element in the \r
458 <PackageName>.spd file\r
aa0bf4f4 459 * Each line contains Protocol base name then the global variable name and\r
460 then the hex value of the Protocol GUID.\r
461\r
64fcaead 462Example Protocol Entries (NOTE: The Guid entry is a single line in the SPD file):\r

543Notes:\r
544------\r
13421853 545The EDK II represents significant changes in the structure of the EDK.\r
aa0bf4f4 546Therefore it is very difficult to isolate all of the changes of this version of\r
547the EDK with the previous (EDK 1.0) version.\r
548\r
549Of particular note:\r
550\r
13421853 5511) EDK II contains new hardware feature support for the ICH SMBUS Libraries.\r
aa0bf4f4 552 These libraries are provided to make Memory Reference Code (MRC) development\r
553 easier.\r
1465cc8b 5542) The MDE Libraries - The MDE libraries represent significant changes in source\r
aa0bf4f4 555 (with only limited changes in functionality.) These new libraries conform\r
556 to the "MDE Library Specification". \r
5573) The Fat Binary and the EDK Shell Binary Packages are functionally identical\r
558 to the EDK 1.0 version.\r
5594) The EDK tools directory has been expanded to include more tools and more\r
560 tool functionality.\r
5615) The EDK NT32 section has been ported to the new build process, but\r
562 functionally remains the same as the EDK 1.0 version.\r
13421853 5636) The Application "HelloWorld" has been ported to EDK II as well.\r
