! 25: GENERAL
! 26:
! 27: I (Philip Hazel) have no experience of Windows or VMS sytems and how their
! 28: libraries work. The items in the PCRE distribution and Makefile that relate to
! 29: anything other than Linux systems are untested by me.
! 30:
! 31: There are some other comments and files (including some documentation in CHM
! 32: format) in the Contrib directory on the FTP site:
! 33:
! 34: ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib
! 35:
! 36: The basic PCRE library consists entirely of code written in Standard C, and so
! 37: should compile successfully on any system that has a Standard C compiler and
! 38: library. The C++ wrapper functions are a separate issue (see below).
! 39:
! 40: The PCRE distribution includes a "configure" file for use by the configure/make
! 41: (autotools) build system, as found in many Unix-like environments. The README
! 42: file contains information about the options for "configure".
! 43:
! 44: There is also support for CMake, which some users prefer, especially in Windows
! 45: environments, though it can also be run in Unix-like environments. See the
! 46: section entitled "Building PCRE on Windows with CMake" below.
! 47:
! 48: Versions of config.h and pcre.h are distributed in the PCRE tarballs under the
! 49: names config.h.generic and pcre.h.generic. These are provided for those who
! 50: build PCRE without using "configure" or CMake. If you use "configure" or CMake,
! 51: the .generic versions are not used.
! 52:
! 53:
! 54: GENERIC INSTRUCTIONS FOR THE PCRE C LIBRARY
! 55:
! 56: The following are generic instructions for building the PCRE C library "by
! 57: hand". If you are going to use CMake, this section does not apply to you; you
! 58: can skip ahead to the CMake section.
! 59:
! 60: (1) Copy or rename the file config.h.generic as config.h, and edit the macro
! 61: settings that it contains to whatever is appropriate for your environment.
! 62:
! 63: In particular, you can alter the definition of the NEWLINE macro to
! 64: specify what character(s) you want to be interpreted as line terminators.
! 65: In an EBCDIC environment, you MUST change NEWLINE, because its default
! 66: value is 10, an ASCII LF. The usual EBCDIC newline character is 21 (0x15,
! 67: NL), though in some cases it may be 37 (0x25).
! 68:
! 69: When you compile any of the PCRE modules, you must specify -DHAVE_CONFIG_H
! 70: to your compiler so that config.h is included in the sources.
! 71:
! 72: An alternative approach is not to edit config.h, but to use -D on the
! 73: compiler command line to make any changes that you need to the
! 74: configuration options. In this case -DHAVE_CONFIG_H must not be set.
! 75:
! 76: NOTE: There have been occasions when the way in which certain parameters
! 77: in config.h are used has changed between releases. (In the configure/make
! 78: world, this is handled automatically.) When upgrading to a new release,
! 79: you are strongly advised to review config.h.generic before re-using what
! 80: you had previously.
! 81:
! 82: (2) Copy or rename the file pcre.h.generic as pcre.h.
! 83:
! 84: (3) EITHER:
! 85: Copy or rename file pcre_chartables.c.dist as pcre_chartables.c.
! 86:
! 87: OR:
! 88: Compile dftables.c as a stand-alone program (using -DHAVE_CONFIG_H if
! 89: you have set up config.h), and then run it with the single argument
! 90: "pcre_chartables.c". This generates a set of standard character tables
! 91: and writes them to that file. The tables are generated using the default
! 92: C locale for your system. If you want to use a locale that is specified
! 93: by LC_xxx environment variables, add the -L option to the dftables
! 94: command. You must use this method if you are building on a system that
! 95: uses EBCDIC code.
! 96:
! 97: The tables in pcre_chartables.c are defaults. The caller of PCRE can
! 98: specify alternative tables at run time.
! 99:
! 100: (4) Ensure that you have the following header files:
! 101:
! 102: pcre_internal.h
! 103: ucp.h
! 104:
! 105: (5) For an 8-bit library, compile the following source files, setting
! 106: -DHAVE_CONFIG_H as a compiler option if you have set up config.h with your
! 107: configuration, or else use other -D settings to change the configuration
! 108: as required.
! 109:
! 110: pcre_byte_order.c
! 111: pcre_chartables.c
! 112: pcre_compile.c
! 113: pcre_config.c
! 114: pcre_dfa_exec.c
! 115: pcre_exec.c
! 116: pcre_fullinfo.c
! 117: pcre_get.c
! 118: pcre_globals.c
! 119: pcre_jit_compile.c
! 120: pcre_maketables.c
! 121: pcre_newline.c
! 122: pcre_ord2utf8.c
! 123: pcre_refcount.c
! 124: pcre_string_utils.c
! 125: pcre_study.c
! 126: pcre_tables.c
! 127: pcre_ucd.c
! 128: pcre_valid_utf8.c
! 129: pcre_version.c
! 130: pcre_xclass.c
! 131:
! 132: Make sure that you include -I. in the compiler command (or equivalent for
! 133: an unusual compiler) so that all included PCRE header files are first
! 134: sought in the current directory. Otherwise you run the risk of picking up
! 135: a previously-installed file from somewhere else.
! 136:
! 137: Note that you must still compile pcre_jit_compile.c, even if you have not
! 138: defined SUPPORT_JIT in config.h, because when JIT support is not
! 139: configured, dummy functions are compiled. When JIT support IS configured,
! 140: pcre_jit_compile.c #includes sources from the sljit subdirectory, where
! 141: there should be 16 files, all of whose names begin with "sljit".
! 142:
! 143: (6) Now link all the compiled code into an object library in whichever form
! 144: your system keeps such libraries. This is the basic PCRE C 8-bit library.
! 145: If your system has static and shared libraries, you may have to do this
! 146: once for each type.
! 147:
! 148: (7) If you want to build a 16-bit library (as well as, or instead of the 8-bit
! 149: or 32-bit libraries) repeat steps 5-6 with the following files:
! 150:
! 151: pcre16_byte_order.c
! 152: pcre16_chartables.c
! 153: pcre16_compile.c
! 154: pcre16_config.c
! 155: pcre16_dfa_exec.c
! 156: pcre16_exec.c
! 157: pcre16_fullinfo.c
! 158: pcre16_get.c
! 159: pcre16_globals.c
! 160: pcre16_jit_compile.c
! 161: pcre16_maketables.c
! 162: pcre16_newline.c
! 163: pcre16_ord2utf16.c
! 164: pcre16_refcount.c
! 165: pcre16_string_utils.c
! 166: pcre16_study.c
! 167: pcre16_tables.c
! 168: pcre16_ucd.c
! 169: pcre16_utf16_utils.c
! 170: pcre16_valid_utf16.c
! 171: pcre16_version.c
! 172: pcre16_xclass.c
! 173:
! 174: (8) If you want to build a 16-bit library (as well as, or instead of the 8-bit
! 175: or 32-bit libraries) repeat steps 5-6 with the following files:
! 176:
! 177: pcre32_byte_order.c
! 178: pcre32_chartables.c
! 179: pcre32_compile.c
! 180: pcre32_config.c
! 181: pcre32_dfa_exec.c
! 182: pcre32_exec.c
! 183: pcre32_fullinfo.c
! 184: pcre32_get.c
! 185: pcre32_globals.c
! 186: pcre32_jit_compile.c
! 187: pcre32_maketables.c
! 188: pcre32_newline.c
! 189: pcre32_ord2utf32.c
! 190: pcre32_refcount.c
! 191: pcre32_string_utils.c
! 192: pcre32_study.c
! 193: pcre32_tables.c
! 194: pcre32_ucd.c
! 195: pcre32_utf32_utils.c
! 196: pcre32_valid_utf32.c
! 197: pcre32_version.c
! 198: pcre32_xclass.c
! 199:
! 200: (9) If you want to build the POSIX wrapper functions (which apply only to the
! 201: 8-bit library), ensure that you have the pcreposix.h file and then compile
! 202: pcreposix.c (remembering -DHAVE_CONFIG_H if necessary). Link the result
! 203: (on its own) as the pcreposix library.
! 204:
! 205: (10) The pcretest program can be linked with any combination of the 8-bit,
! 206: 16-bit and 32-bit libraries (depending on what you selected in config.h).
! 207: Compile pcretest.c and pcre_printint.c (again, don't forget
! 208: -DHAVE_CONFIG_H) and link them together with the appropriate library/ies.
! 209: If you compiled an 8-bit library, pcretest also needs the pcreposix
! 210: wrapper library unless you compiled it with -DNOPOSIX.
! 211:
! 212: (11) Run pcretest on the testinput files in the testdata directory, and check
! 213: that the output matches the corresponding testoutput files. There are
! 214: comments about what each test does in the section entitled "Testing PCRE"
! 215: in the README file. If you compiled more than one of the 8-bit, 16-bit and
! 216: 32-bit libraries, you need to run pcretest with the -16 option to do
! 217: 16-bit tests and with the -32 option to do 32-bit tests.
! 218:
! 219: Some tests are relevant only when certain build-time options are selected.
! 220: For example, test 4 is for UTF-8/UTF-16/UTF-32 support, and will not run
! 221: if you have built PCRE without it. See the comments at the start of each
! 222: testinput file. If you have a suitable Unix-like shell, the RunTest script
! 223: will run the appropriate tests for you. The command "RunTest list" will
! 224: output a list of all the tests.
! 225:
! 226: Note that the supplied files are in Unix format, with just LF characters
! 227: as line terminators. You may need to edit them to change this if your
! 228: system uses a different convention. If you are using Windows, you probably
! 229: should use the wintestinput3 file instead of testinput3 (and the
! 230: corresponding output file). This is a locale test; wintestinput3 sets the
! 231: locale to "french" rather than "fr_FR", and there some minor output
! 232: differences.
! 233:
! 234: (12) If you have built PCRE with SUPPORT_JIT, the JIT features will be tested
! 235: by the testdata files. However, you might also like to build and run
! 236: the freestanding JIT test program, pcre_jit_test.c.
! 237:
! 238: (13) If you want to use the pcregrep command, compile and link pcregrep.c; it
! 239: uses only the basic 8-bit PCRE library (it does not need the pcreposix
! 240: library).
! 241:
! 242:
! 243: THE C++ WRAPPER FUNCTIONS
! 244:
! 245: The PCRE distribution also contains some C++ wrapper functions and tests,
! 246: applicable to the 8-bit library, which were contributed by Google Inc. On a
! 247: system that can use "configure" and "make", the functions are automatically
! 248: built into a library called pcrecpp. It should be straightforward to compile
! 249: the .cc files manually on other systems. The files called xxx_unittest.cc are
! 250: test programs for each of the corresponding xxx.cc files.
! 251:
! 252:
! 253: BUILDING FOR VIRTUAL PASCAL
! 254:
! 255: A script for building PCRE using Borland's C++ compiler for use with VPASCAL
! 256: was contributed by Alexander Tokarev. Stefan Weber updated the script and added
! 257: additional files. The following files in the distribution are for building PCRE
! 258: for use with VP/Borland: makevp_c.txt, makevp_l.txt, makevp.bat, pcregexp.pas.
! 259:
! 260:
! 261: STACK SIZE IN WINDOWS ENVIRONMENTS
! 262:
! 263: The default processor stack size of 1Mb in some Windows environments is too
! 264: small for matching patterns that need much recursion. In particular, test 2 may
! 265: fail because of this. Normally, running out of stack causes a crash, but there
! 266: have been cases where the test program has just died silently. See your linker
! 267: documentation for how to increase stack size if you experience problems. The
! 268: Linux default of 8Mb is a reasonable choice for the stack, though even that can
! 269: be too small for some pattern/subject combinations.
! 270:
! 271: PCRE has a compile configuration option to disable the use of stack for
! 272: recursion so that heap is used instead. However, pattern matching is
! 273: significantly slower when this is done. There is more about stack usage in the
! 274: "pcrestack" documentation.
! 275:
! 276:
! 277: LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
! 278:
! 279: If you want to statically link a program against a PCRE library in the form of
! 280: a non-dll .a file, you must define PCRE_STATIC before including pcre.h or
! 281: pcrecpp.h, otherwise the pcre_malloc() and pcre_free() exported functions will
! 282: be declared __declspec(dllimport), with unwanted results.
! 283:
! 284:
! 285: CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
! 286:
! 287: It is possible to compile programs to use different calling conventions using
! 288: MSVC. Search the web for "calling conventions" for more information. To make it
! 289: easier to change the calling convention for the exported functions in the
! 290: PCRE library, the macro PCRE_CALL_CONVENTION is present in all the external
! 291: definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
! 292: not set, it defaults to empty; the default calling convention is then used
! 293: (which is what is wanted most of the time).
! 294:
! 295:
! 296: COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE ON WINDOWS WITH CMAKE")
! 297:
! 298: There are two ways of building PCRE using the "configure, make, make install"
! 299: paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
! 300: the same thing; they are completely different from each other. There is also
! 301: support for building using CMake, which some users find a more straightforward
! 302: way of building PCRE under Windows.
! 303:
! 304: The MinGW home page (http://www.mingw.org/) says this:
! 305:
! 306: MinGW: A collection of freely available and freely distributable Windows
! 307: specific header files and import libraries combined with GNU toolsets that
! 308: allow one to produce native Windows programs that do not rely on any
! 309: 3rd-party C runtime DLLs.
! 310:
! 311: The Cygwin home page (http://www.cygwin.com/) says this:
! 312:
! 313: Cygwin is a Linux-like environment for Windows. It consists of two parts:
! 314:
! 315: . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
! 316: substantial Linux API functionality
! 317:
! 318: . A collection of tools which provide Linux look and feel.
! 319:
! 320: The Cygwin DLL currently works with all recent, commercially released x86 32
! 321: bit and 64 bit versions of Windows, with the exception of Windows CE.
! 322:
! 323: On both MinGW and Cygwin, PCRE should build correctly using:
! 324:
! 325: ./configure && make && make install
! 326:
! 327: This should create two libraries called libpcre and libpcreposix, and, if you
! 328: have enabled building the C++ wrapper, a third one called libpcrecpp. These are
! 329: independent libraries: when you link with libpcreposix or libpcrecpp you must
! 330: also link with libpcre, which contains the basic functions. (Some earlier
! 331: releases of PCRE included the basic libpcre functions in libpcreposix. This no
! 332: longer happens.)
! 333:
! 334: A user submitted a special-purpose patch that makes it easy to create
! 335: "pcre.dll" under mingw32 using the "msys" environment. It provides "pcre.dll"
! 336: as a special target. If you use this target, no other files are built, and in
! 337: particular, the pcretest and pcregrep programs are not built. An example of how
! 338: this might be used is:
! 339:
! 340: ./configure --enable-utf --disable-cpp CFLAGS="-03 -s"; make pcre.dll
! 341:
! 342: Using Cygwin's compiler generates libraries and executables that depend on
! 343: cygwin1.dll. If a library that is generated this way is distributed,
! 344: cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
! 345: licence, this forces not only PCRE to be under the GPL, but also the entire
! 346: application. A distributor who wants to keep their own code proprietary must
! 347: purchase an appropriate Cygwin licence.
! 348:
! 349: MinGW has no such restrictions. The MinGW compiler generates a library or
! 350: executable that can run standalone on Windows without any third party dll or
! 351: licensing issues.
! 352:
! 353: But there is more complication:
! 354:
! 355: If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
! 356: to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
! 357: front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
! 358: gcc and MinGW's gcc). So, a user can:
! 359:
! 360: . Build native binaries by using MinGW or by getting Cygwin and using
! 361: -mno-cygwin.
! 362:
! 363: . Build binaries that depend on cygwin1.dll by using Cygwin with the normal
! 364: compiler flags.
! 365:
! 366: The test files that are supplied with PCRE are in UNIX format, with LF
! 367: characters as line terminators. Unless your PCRE library uses a default newline
! 368: option that includes LF as a valid newline, it may be necessary to change the
! 369: line terminators in the test files to get some of the tests to work.
! 370:
! 371:
! 372: BUILDING PCRE ON WINDOWS WITH CMAKE
! 373:
! 374: CMake is an alternative configuration facility that can be used instead of
! 375: "configure". CMake creates project files (make files, solution files, etc.)
! 376: tailored to numerous development environments, including Visual Studio,
! 377: Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
! 378: spaces in the names for your CMake installation and your PCRE source and build
! 379: directories.
! 380:
! 381: The following instructions were contributed by a PCRE user. If they are not
! 382: followed exactly, errors may occur. In the event that errors do occur, it is
! 383: recommended that you delete the CMake cache before attempting to repeat the
! 384: CMake build process. In the CMake GUI, the cache can be deleted by selecting
! 385: "File > Delete Cache".
! 386:
! 387: 1. Install the latest CMake version available from http://www.cmake.org/, and
! 388: ensure that cmake\bin is on your path.
! 389:
! 390: 2. Unzip (retaining folder structure) the PCRE source tree into a source
! 391: directory such as C:\pcre. You should ensure your local date and time
! 392: is not earlier than the file dates in your source dir if the release is
! 393: very new.
! 394:
! 395: 3. Create a new, empty build directory, preferably a subdirectory of the
! 396: source dir. For example, C:\pcre\pcre-xx\build.
! 397:
! 398: 4. Run cmake-gui from the Shell envirornment of your build tool, for example,
! 399: Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try
! 400: to start Cmake from the Windows Start menu, as this can lead to errors.
! 401:
! 402: 5. Enter C:\pcre\pcre-xx and C:\pcre\pcre-xx\build for the source and build
! 403: directories, respectively.
! 404:
! 405: 6. Hit the "Configure" button.
! 406:
! 407: 7. Select the particular IDE / build tool that you are using (Visual
! 408: Studio, MSYS makefiles, MinGW makefiles, etc.)
! 409:
! 410: 8. The GUI will then list several configuration options. This is where
! 411: you can enable UTF-8 support or other PCRE optional features.
! 412:
! 413: 9. Hit "Configure" again. The adjacent "Generate" button should now be
! 414: active.
! 415:
! 416: 10. Hit "Generate".
! 417:
! 418: 11. The build directory should now contain a usable build system, be it a
! 419: solution file for Visual Studio, makefiles for MinGW, etc. Exit from
! 420: cmake-gui and use the generated build system with your compiler or IDE.
! 421: E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE
! 422: solution, select the desired configuration (Debug, or Release, etc.) and
! 423: build the ALL_BUILD project.
! 424:
! 425: 12. If during configuration with cmake-gui you've elected to build the test
! 426: programs, you can execute them by building the test project. E.g., for
! 427: MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
! 428: most recent build configuration is targeted by the tests. A summary of
! 429: test results is presented. Complete test output is subsequently
! 430: available for review in Testing\Temporary under your build dir.
! 431:
! 432:
! 433: USE OF RELATIVE PATHS WITH CMAKE ON WINDOWS
! 434:
! 435: A PCRE user comments as follows: I thought that others may want to know the
! 436: current state of CMAKE_USE_RELATIVE_PATHS support on Windows. Here it is:
! 437:
! 438: -- AdditionalIncludeDirectories is only partially modified (only the
! 439: first path - see below)
! 440: -- Only some of the contained file paths are modified - shown below for
! 441: pcre.vcproj
! 442: -- It properly modifies
! 443:
! 444: I am sure CMake people can fix that if they want to. Until then one will
! 445: need to replace existing absolute paths in project files with relative
! 446: paths manually (e.g. from VS) - relative to project file location. I did
! 447: just that before being told to try CMAKE_USE_RELATIVE_PATHS. Not a big
! 448: deal.

! 458: TESTING WITH RUNTEST.BAT
! 459:
! 460: If configured with CMake, building the test project ("make test" or building
! 461: ALL_TESTS in Visual Studio) creates (and runs) pcre_test.bat (and depending
! 462: on your configuration options, possibly other test programs) in the build
! 463: directory. Pcre_test.bat runs RunTest.Bat with correct source and exe paths.
! 464:
! 465: For manual testing with RunTest.bat, provided the build dir is a subdirectory
! 466: of the source directory: Open command shell window. Chdir to the location
! 467: of your pcretest.exe and pcregrep.exe programs. Call RunTest.bat with
! 468: "..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
! 469:
! 470: To run only a particular test with RunTest.Bat provide a test number argument.
! 471:
! 472: Otherwise:
! 473:
! 474: 1. Copy RunTest.bat into the directory where pcretest.exe and pcregrep.exe
! 475: have been created.
! 476:
! 477: 2. Edit RunTest.bat to indentify the full or relative location of
! 478: the pcre source (wherein which the testdata folder resides), e.g.:
! 479:
! 480: set srcdir=C:\pcre\pcre-8.20
! 481:
! 482: 3. In a Windows command environment, chdir to the location of your bat and
! 483: exe programs.
! 484:
! 485: 4. Run RunTest.bat. Test outputs will automatically be compared to expected
! 486: results, and discrepancies will be identified in the console output.
! 487:
! 488: To independently test the just-in-time compiler, run pcre_jit_test.exe.
! 489: To test pcrecpp, run pcrecpp_unittest.exe, pcre_stringpiece_unittest.exe and
! 490: pcre_scanner_unittest.exe.

! 493: BUILDING UNDER WINDOWS CE WITH VISUAL STUDIO 200x
! 494:
! 495: Vincent Richomme sent a zip archive of files to help with this process. They
! 496: can be found in the file "pcre-vsbuild.zip" in the Contrib directory of the FTP
! 497: site.

! 499:
! 500: BUILDING UNDER WINDOWS WITH BCC5.5
! 501:
! 502: Michael Roy sent these comments about building PCRE under Windows with BCC5.5:
! 503:
! 504: Some of the core BCC libraries have a version of PCRE from 1998 built in, which
! 505: can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a version
! 506: mismatch. I'm including an easy workaround below, if you'd like to include it
! 507: in the non-unix instructions:
! 508:
! 509: When linking a project with BCC5.5, pcre.lib must be included before any of the
! 510: libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command line.
! 511:
! 512:
! 513: BUILDING USING BORLAND C++ BUILDER 2007 (CB2007) AND HIGHER
! 514:
! 515: A PCRE user sent these comments about this environment (see also the comment
! 516: from another user that follows them):
! 517:
! 518: The XE versions of C++ Builder come with a RegularExpressionsCore class which
! 519: contain a version of TPerlRegEx. However, direct use of the C PCRE library may
! 520: be desirable.
! 521:
! 522: The default makevp.bat, however, supplied with PCRE builds a version of PCRE
! 523: that is not usable with any version of C++ Builder because the compiler ships
! 524: with an embedded version of PCRE, version 2.01 from 1998! [See also the note
! 525: about BCC5.5 above.] If you want to use PCRE you'll need to rename the
! 526: functions (pcre_compile to pcre_compile_bcc, etc) or do as I have done and just
! 527: use the 16 bit versions. I'm using std::wstring everywhere anyway. Since the
! 528: embedded version of PCRE does not have the 16 bit function names, there is no
! 529: conflict.
! 530:
! 531: Building PCRE using a C++ Builder static library project file (recommended):
! 532:
! 533: 1. Rename or remove pcre.h, pcreposi.h, and pcreposix.h from your C++ Builder
! 534: original include path.
! 535:
! 536: 2. Download PCRE from pcre.org and extract to a directory.
! 537:
! 538: 3. Rename pcre_chartables.c.dist to pcre_chartables.c, pcre.h.generic to
! 539: pcre.h, and config.h.generic to config.h.
! 540:
! 541: 4. Edit pcre.h and pcre_config.c so that they include config.h.
! 542:
! 543: 5. Edit config.h like so:
! 544:
! 545: Comment out the following lines:
! 546: #define PACKAGE "pcre"
! 547: #define PACKAGE_BUGREPORT ""
! 548: #define PACKAGE_NAME "PCRE"
! 549: #define PACKAGE_STRING "PCRE 8.32"
! 550: #define PACKAGE_TARNAME "pcre"
! 551: #define PACKAGE_URL ""
! 552: #define PACKAGE_VERSION "8.32"
! 553:
! 554: Add the following lines:
! 555: #ifndef SUPPORT_UTF
! 556: #define SUPPORT_UTF 100 // any value is fine
! 557: #endif
! 558:
! 559: #ifndef SUPPORT_UCP
! 560: #define SUPPORT_UCP 101 // any value is fine
! 561: #endif
! 562:
! 563: #ifndef SUPPORT_UCP
! 564: #define SUPPORT_PCRE16 102 // any value is fine
! 565: #endif
! 566:
! 567: #ifndef SUPPORT_UTF8
! 568: #define SUPPORT_UTF8 103 // any value is fine
! 569: #endif
! 570:
! 571: 6. Build a C++ Builder project using the IDE. Go to File / New / Other and
! 572: choose Static Library. You can name it pcre.cbproj or whatever. Now set your
! 573: paths by going to Project / Options. Set the Include path. Do this from the
! 574: "Base" option to apply to both Release and Debug builds. Now add the following
! 575: files to the project:
! 576:
! 577: pcre.h
! 578: pcre16_byte_order.c
! 579: pcre16_chartables.c
! 580: pcre16_compile.c
! 581: pcre16_config.c
! 582: pcre16_dfa_exec.c
! 583: pcre16_exec.c
! 584: pcre16_fullinfo.c
! 585: pcre16_get.c
! 586: pcre16_globals.c
! 587: pcre16_maketables.c
! 588: pcre16_newline.c
! 589: pcre16_ord2utf16.c
! 590: pcre16_printint.c
! 591: pcre16_refcount.c
! 592: pcre16_string_utils.c
! 593: pcre16_study.c
! 594: pcre16_tables.c
! 595: pcre16_ucd.c
! 596: pcre16_utf16_utils.c
! 597: pcre16_valid_utf16.c
! 598: pcre16_version.c
! 599: pcre16_xclass.c
! 600:
! 601: //Optional
! 602: pcre_version.c
! 603:
! 604: 7. After compiling the .lib file, copy the .lib and header files to a project
! 605: you want to use PCRE with. Enjoy.
! 606:
! 607: Optional ... Building PCRE using the makevp.bat file:
! 608:
! 609: 1. Edit makevp_c.txt and makevp_l.txt and change all the names to the 16 bit
! 610: versions.
! 611:
! 612: 2. Edit makevp.bat and set the path to C++ Builder. Run makevp.bat.
! 613:
! 614: Another PCRE user added this comment:
! 615:
! 616: Another approach I successfully used for some years with BCB 5 and 6 was to
! 617: make sure that include and library paths of PCRE are configured before the
! 618: default paths of the IDE in the dialogs where one can manage those paths.
! 619: Afterwards one can open the project files using a text editor and manually add
! 620: the self created library for pcre itself, pcrecpp doesn't ship with the IDE, in
! 621: the library nodes where the IDE manages its own libraries to link against in
! 622: front of the IDE-own libraries. This way one can use the default PCRE function
! 623: names without getting access violations on runtime.

! 628: BUILDING PCRE ON OPENVMS
! 629:
! 630: Stephen Hoffman sent the following, in December 2012:
! 631:
! 632: "Here <http://labs.hoffmanlabs.com/node/1847> is a very short write-up on the
! 633: OpenVMS port and here
! 634:
! 635: <http://labs.hoffmanlabs.com/labsnotes/pcre-vms-8_32.zip>
! 636:
! 637: is a zip with the OpenVMS files, and with one modified testing-related PCRE
! 638: file." This is a port of PCRE 8.32.
! 639:
! 640: Earlier, Dan Mooney sent the following comments about building PCRE on OpenVMS.
! 641: They relate to an older version of PCRE that used fewer source files, so the
! 642: exact commands will need changing. See the current list of source files above.
! 643:
! 644: "It was quite easy to compile and link the library. I don't have a formal
! 645: make file but the attached file [reproduced below] contains the OpenVMS DCL
! 646: commands I used to build the library. I had to add #define
! 647: POSIX_MALLOC_THRESHOLD 10 to pcre.h since it was not defined anywhere.
! 648:
! 649: The library was built on:
! 650: O/S: HP OpenVMS v7.3-1
! 651: Compiler: Compaq C v6.5-001-48BCD
! 652: Linker: vA13-01
! 653:
! 654: The test results did not match 100% due to the issues you mention in your
! 655: documentation regarding isprint(), iscntrl(), isgraph() and ispunct(). I
! 656: modified some of the character tables temporarily and was able to get the
! 657: results to match. Tests using the fr locale did not match since I don't have
! 658: that locale loaded. The study size was always reported to be 3 less than the
! 659: value in the standard test output files."

! 702:
! 703: BUILDING PCRE ON STRATUS OPENVOS
! 704:
! 705: These notes on the port of PCRE to VOS (lightly edited) were supplied by
! 706: Ashutosh Warikoo, whose email address has the local part awarikoo and the
! 707: domain nse.co.in. The port was for version 7.9 in August 2009.
! 708:
! 709: 1. Building PCRE
! 710:
! 711: I built pcre on OpenVOS Release 17.0.1at using GNU Tools 3.4a without any
! 712: problems. I used the following packages to build PCRE:
! 713:
! 714: ftp://ftp.stratus.com/pub/vos/posix/ga/posix.save.evf.gz
! 715:
! 716: Please read and follow the instructions that come with these packages. To start
! 717: the build of pcre, from the root of the package type:
! 718:
! 719: ./build.sh
! 720:
! 721: 2. Installing PCRE
! 722:
! 723: Once you have successfully built PCRE, login to the SysAdmin group, switch to
! 724: the root user, and type
! 725:
! 726: [ !create_dir (master_disk)>usr --if needed ]
! 727: [ !create_dir (master_disk)>usr>local --if needed ]
! 728: !gmake install
! 729:
! 730: This installs PCRE and its man pages into /usr/local. You can add
! 731: (master_disk)>usr>local>bin to your command search paths, or if you are in
! 732: BASH, add /usr/local/bin to the PATH environment variable.
! 733:
! 734: 4. Restrictions
! 735:
! 736: This port requires readline library optionally. However during the build I
! 737: faced some yet unexplored errors while linking with readline. As it was an
! 738: optional component I chose to disable it.
! 739:
! 740: 5. Known Problems
! 741:
! 742: I ran the test suite, but you will have to be your own judge of whether this
! 743: command, and this port, suits your purposes. If you find any problems that
! 744: appear to be related to the port itself, please let me know. Please see the
! 745: build.log file in the root of the package also.
! 746:
! 747:
! 748: BUILDING PCRE ON NATIVE Z/OS AND Z/VM
! 749:
! 750: z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
! 751: The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
! 752: applications can be supported through UNIX System Services, and in such an
! 753: environment PCRE can be built in the same way as in other systems. However, in
! 754: native z/OS (without UNIX System Services) and in z/VM, special ports are
! 755: required. For details, please see this web site:
! 756:
! 757: http://www.zaconsultants.net
