114Notes On Required Tools (MS Windows environment example)\r
115-----------------------\r
116Software Installation Order:\r
117 After installing the compiler tools and your Subversion client, the following\r
118 required tools should be installed in order: \r
119 Java JDK, Apache-Ant, ant-contrib, xmlbeans, saxon8\r
120\r
121Java Development Kit:\r
122 \r
123 The Java Environment Variable must be set before attempting to build.\r
124 i.e. For Sun JDK (see note below*):\r
125 set JAVA_HOME=c:\ Java\jdk1.5.0_06 \r
126 i.e. For Bea Systems:\r
127 set JAVA_HOME=c:\Program Files\Java\jrockit-R26.0.0-jdk1.5.0_04\r
128 \r
129 *When using the Sun JDK5.0\r
130 During installation, you should specify the install directory as C:\Java\r
131 instead of C:\Program Files\(or some other drive letter.) While installing\r
132 to this non-standard location is not required. In use, it seems to work \r
133 more reliably. \r
134 For the JDK, the install path would be C:\Java\jdk1.5.0_06\r
135 For the JRE, the install path would be C:\Java\jre1.5.0_06\r
136 Alternatively, you can specify C:\sunjavajdk and C:\sunjavajre.\r
01d2ed5e 137\r
aa0bf4f4 138 NOTE: You cannot combine the location for the JDK and the JRE, as the JRE\r
139 install removes most of the binaries and libraries installed by the JDK\r
140 install.\r
141\r
142Java Tools:\r
143 The Apache-ANT requires the ANT_HOME environment variable to be set before\r
144 attempting to build:\r
01d2ed5e 145 i.e. set ANT_HOME=c:\<full path to where ant was installed>\r
aa0bf4f4 146\r
147 The ant-contrib.jar file should be installed in the %ANT_HOME%\lib \r
148 directory.\r
149\r
150 The XMLBeans, requires the XMLBEANS_HOME environment variable to be set\r
151 before attempting to build:\r
01d2ed5e 152 i.e. set XMLBEANS_HOME=C:\<full path to where xmlbeans was installed>\r
aa0bf4f4 153\r
154 The saxon8.jar file should be copied to the %XMLBEANS_HOME%\lib directory.\r
155\r
156 The Ant and XMLBean tools are required to be in the path.\r
157 MS system example:\r
158 set PATH=%PATH%;%ANT_HOME%\bin;%XMLBEANS_HOME%\bin\r
159 Linux/OS X bash shell example:\r
160 export PATH=$PATH:${ANT_HOME}/bin:${XMLBEANS_HOME}/bin\r
161 \r
162-------------------------------------------------------------------------------\r
163Quick Start\r
164-----------\r
a032fb4d 165Copy the target.template file in the Tools/Conf directory to target.txt, which\r
166must also be in the Tools/Conf directory.\r
167\r
e3f236c8 168Edit the text file, target.txt, located in the Tools/Conf directory. This \r
a032fb4d 169file contains options for setting the active platform and restricting the build. \r
170The restictions are used to limit the build output by specifying build target(s), \r
171tagname(s) and architecture(s) to less than the full set of possible options. \r
172\r
173The ACTIVE_PLATFORM MUST BE SET. All other options need not be set, however by \r
174unsetting these options (by removing the line from the file, or leaving the Value \r
175empty) will result in all available build possibilites when typing build. By\r
176default EDK II can build a matrix of binaries, using different target types, tool\r
177chain tags and architectures. Options to target.txt file are as follows:\r
178\r
179ACTIVE_PLATFORM = Value REQUIRED\r
180 Where Value is the WORKSPACE relative path and filename of a Framework Platform \r
181 Definition (FPD) File. Example:\r
182\r
183ACTIVE_PLATFORM = MdePkg/MdePkg.fpd\r
184\r
185TARGET = Value OPTIONAL\r
186 Where Value is a list of one or more of the following: DEBUG, RELEASE or a User\r
187 Defined Target type, such as PERF. Example: \r
188\r
189TARGET = DEBUG RELEASE\r
190\r
191TARGET_ARCH = Value OPTIONAL\r
192 Where Value is a list of one or more supported Architectures: IA32, X64, IPF or\r
193 EBC. Example: \r
194\r
195TARGET_ARCH = IA32 X64 EBC\r
196\r
197TOOL_CHAIN_CONF = Value OPTIONAL\r
198 Where Value is the Filename of an alternate tools_def.txt file created by the\r
199 user. The alternate tools_def.txt files must be in the Tools/Conf directory.\r
200 These tool definitions are scoped to the WORKSPACE (location of the EDK \r
201 installation) and cannot be shared between WORKSPACES. (You can copy the files\r
202 from one workspace to another.) Example: \r
203\r
204TOOL_CHAIN_CONF = alfred.txt\r
205\r
206TOOL_CHAIN_TAG = Value OPTIONAL\r
207 Where Value is a list of TagName entries as defined in the tools_def.txt file.\r
208 The TagName can be used to specify different versions of a compiler, i.e., \r
209 gcc 4.0 and gcc 4.1 which will allow you to build binaries with both tool chains \r
210 during the same build - useful during testing of a new compiler tool chain, or \r
211 for changing compiler flags to check out performance with a different set of \r
212 flags than flags used for production. Example:\r
213\r
214TOOL_CHAIN_TAG = GCC40 GCC41\r
215\r
216To clear a restriction, just remove any data after the equal sign. To clear\r
217the TARGET_ARCH limitation that was set above, enter: \r
218\r
219TARGET_ARCH =\r
220\r
221-----------\r
222Copy the tools_def.template file in Tools/Conf to tools_def.txt in the same\r
223directory.\r
e3f236c8 224\r
225Edit the tools definition file, tools_def.txt, also located in the Tools/Conf \r
226directory. This file contains the names of the compiler tool chains and the \r
227location of the compiler binaries. It has been pre-populated with the standard \r
228location for the Microsoft tool chains and includes the standard location of \r
a032fb4d 229the Intel C Compiler for EFI Byte Code (EBC.) In addition, EDK II provides\r
230support for Cygwin, Linux and OS X GCC compiler tool chains. A script has been\r
231provided in the Tools/gcc directory as well as instructions in obtaining and\r
232building a version of GCC that has been tested. The tools_def.txt file has\r
233the GCC binary locations that are created using this script.\r
234\r
235Both target.txt and tools_def.txt files are formatted as Property = Value, \r
236which must appear on a single line. Spanning a Value entry over multiple\r
237lines is not supported at this time. In the target.txt file, the Property is\r
238a single, uppercase word with underscore characters. These Property names are\r
239fixed by the build system. The tools_def.txt file's Property is an underscore\r
240delimited coding, which supports some user defined values. The coding for\r
241the Property is: TARGET_TAGNAME_ARCH_COMMAND_ATTR The Value, is either a \r
242full path, full path and filename or a reserved word.\r
243\r
244TARGET - DEBUG and RELEASE are predefined, however the user may define one or\r
245 more of their own TARGET types in this file.\r
246\r
247TAGNAME - HOST, MSFT, GCC, INTC are predefined, however the user may define \r
248 one or more of their own TAGNAME keywords in this file.\r
249\r
250ARCH - EDK II supports IA32, X64, IPF and EBC at this time.\r
251\r
252COMMAND - Predefined command codes are listed in the tools_def.txt file, however\r
253 the user can specify additional command codes for their one, non-\r
254 standard tools.\r
255\r
256ATTR - Predefined Attributes are listed in the tools_def.txt file.\r
257\r
258NOTE: The TAGNAME: HOST is reserved and MUST be defined in order to build the\r
259 included Tiano tools from their C source files. These tools have been\r
260 built and tested using both Microsoft and GCC tool chains.\r
261NOTE: The "*" symbol may be used as a wildcard character in most of these\r
262 fields, refer to the tools_def.txt and the "EDK II Build and Packaging\r
263 Architecture Specification" for more details.\r
264\r
265\r
266-----------\r
aa0bf4f4 267Follow the instructions at https://edk2.tianocore.org/servlets/ProjectSource to\r
13421853 268checkout the entire EDK II source tree.\r
aa0bf4f4 269\r
e3f236c8 270In a command window, change to the top level directory of the Edk II sources.\r
aa0bf4f4 271 Set the WORKSPACE environment variable, e.g.:\r
272\r
a032fb4d 273 c:\> set WORKSPACE=C:\MyWork\Edk2\r
aa0bf4f4 274\r
275To test your tool chain setup and to build the Supplied Tools, execute:\r
a032fb4d 276 c:\MyWork\Edk2\> edksetup\r
aa0bf4f4 277\r
278(This command will be referred to as the setup command throughout the rest of\r
279this document.)\r
280 NOTE: You should run the setup command at the start of every session.\r
281 This configures the environment to include the TianoTools and the\r
282 Java applications and libraries.\r
283\r
a032fb4d 284If you are confident that none of the tool tool sources have changed, and you\r
285only want to set up the workspace environment you may execute:\r
286 c:\MyWork\Edk2\> edksetup skip\r
287\r
aa0bf4f4 288Once this is completed, you are ready to test the Build, by executing:\r
a032fb4d 289 c:\MyWork\Edk2\> build\r
aa0bf4f4 290\r
e3f236c8 291This command builds active platform specified in text file target.txt. If \r
292active platform is not specified, go to sub-directory which contains FPD files and\r
293type build. More information about active platform policy reference to specification\r
294<<EDK II Build and Packaging Architecture Specification>>.\r
90f7b6a8 295\r
aa0bf4f4 296-------------------------\r
e3f236c8 297Individual Platform Builds\r
aa0bf4f4 298-------------------------\r
e3f236c8 299After running the setup command, you can build individual platforms.\r
300 In the command window, \r
301 1. Set active platform in target.txt, and type "build" in whatever directory;\r
302 2. or cd to the platform (FPD file) that you want to build, and just type:\r
a032fb4d 303 c:\MyWork\Edk2\EdkNt32Pkg\> build\r
e3f236c8 304\r
305 Note that active platform with the high priority to build, that means active \r
306 platform will be built even if exists FPD file under current directory. More \r
307 information about active platform policy reference to specification\r
308 <<EDK II Build and Packaging Architecture Specification>>. \r
aa0bf4f4 309\r
a032fb4d 310Go to <full build path>\DEBUG\MSFT\IA32 and execute SecMain.exe\r
e3f236c8 311to run the Nt32 emulation platform under Microsoft Windows.\r
aa0bf4f4 312\r
03fed93e 313To exit the Nt32 emulation platform, you may type reset at the EFI Shell>\r
314command prompt. Alternately, you may use the Graphical interface, Boot\r
315Maintenance Manager screen's Reset System command.\r
316\r
aa0bf4f4 317------------------------\r
318Individual Module Builds\r
319------------------------\r
320After running the setup command, you can build individual modules.\r
321 In the command window, cd to the module that you want to build, and just\r
322 type:\r
a032fb4d 323 c:\MyWork\Edk2\MdePkg\Library\BaseLib\> build\r
e3f236c8 324\r
325 Note active platform must be set for individual module build. \r
aa0bf4f4 326\r
327-------------------------------------------------------------------------------\r
328A Word on Apache-ANT\r
329--------------------\r
330The Apache-ANT program is a build tool that uses XML-based project files.\r
331Similar to Makefiles, these project files may contain multiple targets. Most\r
a032fb4d 332build.xml files in EDK II are auto-generated; any edits performed on the\r
333build.xml files will be overwritten the next time build is executed.\r
aa0bf4f4 334\r
a032fb4d 335Pre-defined targets in the build.xml file include:\r
aa0bf4f4 336 all - This target builds binaries for defined architectures\r
337 clean - This target removes object files generated by commands\r
338 cleanall - This target removes all generated files and directories.\r
339\r
340A Word on GCC tool chain\r
341------------------------\r
a032fb4d 342EDK II will not compile with a standard Linux gcc tool chain. While Linux\r
343distributions are usually based on ELF, EDK II requires a version of gcc \r
344that is configured to produce PE-COFF images. You will find a script in \r
345edk2/Tools/gcc that will download, configure, compile, and install a gcc \r
3464.X cross-compile tool chain for EDK II development. It has support for \r
347the IA32 architecture. It can be built and run on Cygwin, Linux, and many \r
348other POSIX compliant host operating environments. There are a few tools\r
349that you will need on your host computer in order to compile the tool \r
350chain. Among them are bash, gcc, gmake, curl (or wget).\r

353\r
354General Information:\r
355=============================================================== \r
356Mechanisms:\r
357----------\r
8fb9e6b8 358A brief overview:\r
aa0bf4f4 359\r
360A) Surface Area Package Description (SPD) file contains information about the\r
361modules that the package contains, including the location of all MSA files, and\r
362public library names and headers that might be provided by a module in the\r
363package. Packages are defined by SPD files. (Found in the root of the Package\r
a032fb4d 364subdirectory (i.e. EdkNt32Pkg)) The SPD is further explained in the "EDK Build \r
365and Packaging Architecture Specification" document.\r
aa0bf4f4 366 \r
367B) Module Surface Area Definition (MSA) files. A description of a module's \r
368surface area, with all module specific default flags and features specified.\r
369Refer to the "Module Surface Area Architecture Specification" for additional\r
a032fb4d 370details. The MSA is further explained in the "EDK II Build Packaging Architecture \r
371Specification" document.\r
372\r
373C) Framework Platform Description (FPD) files. A description of a platform's\r
374surface are, including a list of modules that are needed by the platform. To\r
375support individual module builds, developers are not required to provide\r
376information about specific flash devices, nor flash device layout. There are\r
377specific sections in the FPD file that do control aspects of the build, such \r
378as the Supported Architectures and Build Targets, as well as the tool flags \r
379that are used to create the binary files. A valid platform file can specify \r
380zero or more modules, so individual modules can be compiled within the context\r
381of a platform (FPD) definition.\r
382\r
383D) Platform Configuration Database (PCD). A platform database which contains a\r
aa0bf4f4 384variety of current platform settings or directives by which a driver or\r
385application can interact with. The PCD is defined by the PCD_Protocol (This is\r
386further explained in the "Platform Configuration Database Infrastructure \r
387Description" document.\r
388\r
a032fb4d 389E) Library Class. A library class is a logical grouping of similar functions.\r
aa0bf4f4 390When developing components, the module surface area declares the class of\r
a032fb4d 391libraries that can be used by the component. The MSA and SPD files can specify\r
392a recommended instance of the library that a platform integrator may select,\r
393however this is only a recommendation. The PI may choose to select a different\r
394library instance to be used during compilation/linking. All library type modules \r
395must include header files in their distribution package, as well as their MSA\r
396files. Components, on the other hand, need only provide an MSA and either source\r
397or binary files when distributing packages. The Library Classes are further \r
398explained in the "EDK II Build and Packaging Architecture Specification" \r
399document.\r
aa0bf4f4 400\r
401=========================================================================\r
402The common operations by developers of new modules are:\r
403-------------------------------------------------------\r
404\r
4051) How to manually create a new module in a package:\r
406 - The module source code must first be created in an appropriate directory\r
407 (under the package the module is to be a part of.) \r
408 - An MSA file must be created, spelling out all aspects of the module.\r
409 - The MSA must be added to the SPD for the package to include the module.\r
410\r
411-----------------------------------------\r
4122) Add/Remove module(s) to/from a package:\r
413\r
414 - Setup environment as Build\r
415 - Add a module to a package\r
e3f236c8 416 * Generate the module SurfaceArea description file\r
417 * Add a new <Filename> element under <MsaFiles> into\r
aa0bf4f4 418 <PackageDir>\<PackageName>.spd, using relative path to package\r
e3f236c8 419 * Add a new <ModuleSA> entry under each <FrameworkModules> into\r
420 <PackageDir>\<PackageName>.fpd file if necessary. \r
aa0bf4f4 421\r
422 - Remove a module from a package\r
e3f236c8 423 * Comment out or remove corresponding <Filename> element under <MsaFiles>\r

4293) How to manually create a package:\r
430 - Identify the modules that are to be members of the project.\r
431 - Identify the Variables and Guids required in and of the Package (including\r
432 consumption/production information).\r
433 - Create an SPD file defining these modules and calling out their MSA files.\r
e3f236c8 434 - add a new <Filename> element under <PackageList> into \r
435 Tools\Conf\FrameworkDatabase.db, using the relative path to workspace. \r

528Notes:\r
529------\r
13421853 530The EDK II represents significant changes in the structure of the EDK.\r
aa0bf4f4 531Therefore it is very difficult to isolate all of the changes of this version of\r
532the EDK with the previous (EDK 1.0) version.\r
533\r
534Of particular note:\r
535\r
13421853 5361) EDK II contains new hardware feature support for the ICH SMBUS Libraries.\r
aa0bf4f4 537 These libraries are provided to make Memory Reference Code (MRC) development\r
538 easier.\r
1465cc8b 5392) The MDE Libraries - The MDE libraries represent significant changes in source\r
aa0bf4f4 540 (with only limited changes in functionality.) These new libraries conform\r
541 to the "MDE Library Specification". \r
5423) The Fat Binary and the EDK Shell Binary Packages are functionally identical\r
543 to the EDK 1.0 version.\r
5444) The EDK tools directory has been expanded to include more tools and more\r
545 tool functionality.\r
5465) The EDK NT32 section has been ported to the new build process, but\r
547 functionally remains the same as the EDK 1.0 version.\r
13421853 5486) The Application "HelloWorld" has been ported to EDK II as well.\r
