   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 32-bit library (as well as, or instead of the 8-bit
  175:      or 16-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.
  449: 
  450: AdditionalIncludeDirectories="E:\builds\pcre\build;E:\builds\pcre\pcre-7.5;"
  451: AdditionalIncludeDirectories=".;E:\builds\pcre\pcre-7.5;"
  452: 
  453: RelativePath="pcre.h"
  454: RelativePath="pcre_chartables.c"
  455: RelativePath="pcre_chartables.c.rule"
  456: 
  457: 
  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.
  491: 
  492: 
  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.
  498: 
  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.
  624: 
  625:   <ALLLIB value="libpcre.lib $(LIBFILES) $(LIBRARIES) import32.lib cp32mt.lib"/>

  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."

  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:
