21: GENERAL
22:
23: I (Philip Hazel) have no experience of Windows or VMS sytems and how their
24: libraries work. The items in the PCRE distribution and Makefile that relate to
25: anything other than Linux systems are untested by me.
26:
27: There are some other comments and files (including some documentation in CHM
28: format) in the Contrib directory on the FTP site:
29:
30: ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib
31:
32: The basic PCRE library consists entirely of code written in Standard C, and so
33: should compile successfully on any system that has a Standard C compiler and
34: library. The C++ wrapper functions are a separate issue (see below).
35:
36: The PCRE distribution includes a "configure" file for use by the configure/make
37: (autotools) build system, as found in many Unix-like environments. The README
38: file contains information about the options for "configure".
39:
40: There is also support for CMake, which some users prefer, especially in Windows
41: environments, though it can also be run in Unix-like environments. See the
42: section entitled "Building PCRE on Windows with CMake" below.
43:
44: Versions of config.h and pcre.h are distributed in the PCRE tarballs under the
45: names config.h.generic and pcre.h.generic. These are provided for those who
46: build PCRE without using "configure" or CMake. If you use "configure" or CMake,
47: the .generic versions are not used.
48:
49:
50: GENERIC INSTRUCTIONS FOR THE PCRE C LIBRARY
51:
52: The following are generic instructions for building the PCRE C library "by
53: hand":
54:
55: (1) Copy or rename the file config.h.generic as config.h, and edit the macro
56: settings that it contains to whatever is appropriate for your environment.
57: In particular, if you want to force a specific value for newline, you can
58: define the NEWLINE macro. When you compile any of the PCRE modules, you
59: must specify -DHAVE_CONFIG_H to your compiler so that config.h is included
60: in the sources.
61:
62: An alternative approach is not to edit config.h, but to use -D on the
63: compiler command line to make any changes that you need to the
64: configuration options. In this case -DHAVE_CONFIG_H must not be set.
65:
66: NOTE: There have been occasions when the way in which certain parameters
67: in config.h are used has changed between releases. (In the configure/make
68: world, this is handled automatically.) When upgrading to a new release,
69: you are strongly advised to review config.h.generic before re-using what
70: you had previously.
71:
72: (2) Copy or rename the file pcre.h.generic as pcre.h.
73:
74: (3) EITHER:
75: Copy or rename file pcre_chartables.c.dist as pcre_chartables.c.
76:
77: OR:
78: Compile dftables.c as a stand-alone program (using -DHAVE_CONFIG_H if
79: you have set up config.h), and then run it with the single argument
80: "pcre_chartables.c". This generates a set of standard character tables
81: and writes them to that file. The tables are generated using the default
82: C locale for your system. If you want to use a locale that is specified
83: by LC_xxx environment variables, add the -L option to the dftables
84: command. You must use this method if you are building on a system that
85: uses EBCDIC code.
86:
87: The tables in pcre_chartables.c are defaults. The caller of PCRE can
88: specify alternative tables at run time.
89:
90: (4) Ensure that you have the following header files:
91:
92: pcre_internal.h
93: ucp.h
94:
95: (5) For an 8-bit library, compile the following source files, setting
96: -DHAVE_CONFIG_H as a compiler option if you have set up config.h with your
97: configuration, or else use other -D settings to change the configuration
98: as required.
99:
100: pcre_byte_order.c
101: pcre_chartables.c
102: pcre_compile.c
103: pcre_config.c
104: pcre_dfa_exec.c
105: pcre_exec.c
106: pcre_fullinfo.c
107: pcre_get.c
108: pcre_globals.c
109: pcre_maketables.c
110: pcre_newline.c
111: pcre_ord2utf8.c
112: pcre_refcount.c
113: pcre_string_utils.c
114: pcre_study.c
115: pcre_tables.c
116: pcre_ucd.c
117: pcre_valid_utf8.c
118: pcre_version.c
119: pcre_xclass.c
120:
121: Make sure that you include -I. in the compiler command (or equivalent for
122: an unusual compiler) so that all included PCRE header files are first
123: sought in the current directory. Otherwise you run the risk of picking up
124: a previously-installed file from somewhere else.
125:
126: (6) If you have defined SUPPORT_JIT in config.h, you must also compile
127:
128: pcre_jit_compile.c
129:
130: This file #includes sources from the sljit subdirectory, where there
131: should be 16 files, all of whose names begin with "sljit".
132:
133: (7) Now link all the compiled code into an object library in whichever form
134: your system keeps such libraries. This is the basic PCRE C 8-bit library.
135: If your system has static and shared libraries, you may have to do this
136: once for each type.
137:
138: (8) If you want to build a 16-bit library (as well as, or instead of the 8-bit
139: library) repeat steps 5-7 with the following files:
140:
141: pcre16_byte_order.c
142: pcre16_chartables.c
143: pcre16_compile.c
144: pcre16_config.c
145: pcre16_dfa_exec.c
146: pcre16_exec.c
147: pcre16_fullinfo.c
148: pcre16_get.c
149: pcre16_globals.c
150: pcre16_jit_compile.c (if SUPPORT_JIT is defined)
151: pcre16_maketables.c
152: pcre16_newline.c
153: pcre16_ord2utf16.c
154: pcre16_refcount.c
155: pcre16_string_utils.c
156: pcre16_study.c
157: pcre16_tables.c
158: pcre16_ucd.c
159: pcre16_utf16_utils.c
160: pcre16_valid_utf16.c
161: pcre16_version.c
162: pcre16_xclass.c
163:
164: (9) If you want to build the POSIX wrapper functions (which apply only to the
165: 8-bit library), ensure that you have the pcreposix.h file and then compile
166: pcreposix.c (remembering -DHAVE_CONFIG_H if necessary). Link the result
167: (on its own) as the pcreposix library.
168:
169: (10) The pcretest program can be linked with either or both of the 8-bit and
170: 16-bit libraries (depending on what you selected in config.h). Compile
171: pcretest.c and pcre_printint.c (again, don't forget -DHAVE_CONFIG_H) and
172: link them together with the appropriate library/ies. If you compiled an
173: 8-bit library, pcretest also needs the pcreposix wrapper library unless
174: you compiled it with -DNOPOSIX.
175:
176: (11) Run pcretest on the testinput files in the testdata directory, and check
177: that the output matches the corresponding testoutput files. There are
178: comments about what each test does in the section entitled "Testing PCRE"
179: in the README file. If you compiled both an 8-bit and a 16-bit library,
180: you need to run pcretest with the -16 option to do 16-bit tests.
181:
182: Some tests are relevant only when certain build-time options are selected.
183: For example, test 4 is for UTF-8 or UTF-16 support, and will not run if
184: you have built PCRE without it. See the comments at the start of each
185: testinput file. If you have a suitable Unix-like shell, the RunTest script
186: will run the appropriate tests for you.
187:
188: Note that the supplied files are in Unix format, with just LF characters
189: as line terminators. You may need to edit them to change this if your
190: system uses a different convention. If you are using Windows, you probably
191: should use the wintestinput3 file instead of testinput3 (and the
192: corresponding output file). This is a locale test; wintestinput3 sets the
193: locale to "french" rather than "fr_FR", and there some minor output
194: differences.
195:
196: (12) If you have built PCRE with SUPPORT_JIT, the JIT features will be tested
197: by the testdata files. However, you might also like to build and run
198: the JIT test program, pcre_jit_test.c.
199:
200: (13) If you want to use the pcregrep command, compile and link pcregrep.c; it
201: uses only the basic 8-bit PCRE library (it does not need the pcreposix
202: library).
203:
204:
205: THE C++ WRAPPER FUNCTIONS
206:
207: The PCRE distribution also contains some C++ wrapper functions and tests,
208: applicable to the 8-bit library, which were contributed by Google Inc. On a
209: system that can use "configure" and "make", the functions are automatically
210: built into a library called pcrecpp. It should be straightforward to compile
211: the .cc files manually on other systems. The files called xxx_unittest.cc are
212: test programs for each of the corresponding xxx.cc files.
213:
214:
215: BUILDING FOR VIRTUAL PASCAL
216:
217: A script for building PCRE using Borland's C++ compiler for use with VPASCAL
218: was contributed by Alexander Tokarev. Stefan Weber updated the script and added
219: additional files. The following files in the distribution are for building PCRE
220: for use with VP/Borland: makevp_c.txt, makevp_l.txt, makevp.bat, pcregexp.pas.
221:
222:
223: STACK SIZE IN WINDOWS ENVIRONMENTS
224:
225: The default processor stack size of 1Mb in some Windows environments is too
226: small for matching patterns that need much recursion. In particular, test 2 may
227: fail because of this. Normally, running out of stack causes a crash, but there
228: have been cases where the test program has just died silently. See your linker
229: documentation for how to increase stack size if you experience problems. The
230: Linux default of 8Mb is a reasonable choice for the stack, though even that can
231: be too small for some pattern/subject combinations.
232:
233: PCRE has a compile configuration option to disable the use of stack for
234: recursion so that heap is used instead. However, pattern matching is
235: significantly slower when this is done. There is more about stack usage in the
236: "pcrestack" documentation.
237:
238:
239: LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
240:
241: If you want to statically link a program against a PCRE library in the form of
242: a non-dll .a file, you must define PCRE_STATIC before including pcre.h or
243: pcrecpp.h, otherwise the pcre_malloc() and pcre_free() exported functions will
244: be declared __declspec(dllimport), with unwanted results.
245:
246:
247: CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
248:
249: It is possible to compile programs to use different calling conventions using
250: MSVC. Search the web for "calling conventions" for more information. To make it
251: easier to change the calling convention for the exported functions in the
252: PCRE library, the macro PCRE_CALL_CONVENTION is present in all the external
253: definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
254: not set, it defaults to empty; the default calling convention is then used
255: (which is what is wanted most of the time).
256:
257:
258: COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE ON WINDOWS WITH CMAKE")
259:
260: There are two ways of building PCRE using the "configure, make, make install"
261: paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
262: the same thing; they are completely different from each other. There is also
263: support for building using CMake, which some users find a more straightforward
264: way of building PCRE under Windows.
265:
266: The MinGW home page (http://www.mingw.org/) says this:
267:
268: MinGW: A collection of freely available and freely distributable Windows
269: specific header files and import libraries combined with GNU toolsets that
270: allow one to produce native Windows programs that do not rely on any
271: 3rd-party C runtime DLLs.
272:
273: The Cygwin home page (http://www.cygwin.com/) says this:
274:
275: Cygwin is a Linux-like environment for Windows. It consists of two parts:
276:
277: . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
278: substantial Linux API functionality
279:
280: . A collection of tools which provide Linux look and feel.
281:
282: The Cygwin DLL currently works with all recent, commercially released x86 32
283: bit and 64 bit versions of Windows, with the exception of Windows CE.
284:
285: On both MinGW and Cygwin, PCRE should build correctly using:
286:
287: ./configure && make && make install
288:
289: This should create two libraries called libpcre and libpcreposix, and, if you
290: have enabled building the C++ wrapper, a third one called libpcrecpp. These are
291: independent libraries: when you link with libpcreposix or libpcrecpp you must
292: also link with libpcre, which contains the basic functions. (Some earlier
293: releases of PCRE included the basic libpcre functions in libpcreposix. This no
294: longer happens.)
295:
296: A user submitted a special-purpose patch that makes it easy to create
297: "pcre.dll" under mingw32 using the "msys" environment. It provides "pcre.dll"
298: as a special target. If you use this target, no other files are built, and in
299: particular, the pcretest and pcregrep programs are not built. An example of how
300: this might be used is:
301:
302: ./configure --enable-utf --disable-cpp CFLAGS="-03 -s"; make pcre.dll
303:
304: Using Cygwin's compiler generates libraries and executables that depend on
305: cygwin1.dll. If a library that is generated this way is distributed,
306: cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
307: licence, this forces not only PCRE to be under the GPL, but also the entire
308: application. A distributor who wants to keep their own code proprietary must
309: purchase an appropriate Cygwin licence.
310:
311: MinGW has no such restrictions. The MinGW compiler generates a library or
312: executable that can run standalone on Windows without any third party dll or
313: licensing issues.
314:
315: But there is more complication:
316:
317: If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
318: to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
319: front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
320: gcc and MinGW's gcc). So, a user can:
321:
322: . Build native binaries by using MinGW or by getting Cygwin and using
323: -mno-cygwin.
324:
325: . Build binaries that depend on cygwin1.dll by using Cygwin with the normal
326: compiler flags.
327:
328: The test files that are supplied with PCRE are in UNIX format, with LF
329: characters as line terminators. Unless your PCRE library uses a default newline
330: option that includes LF as a valid newline, it may be necessary to change the
331: line terminators in the test files to get some of the tests to work.
332:
333:
334: BUILDING PCRE ON WINDOWS WITH CMAKE
335:
336: CMake is an alternative configuration facility that can be used instead of
337: "configure". CMake creates project files (make files, solution files, etc.)
338: tailored to numerous development environments, including Visual Studio,
339: Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
340: spaces in the names for your CMake installation and your PCRE source and build
341: directories.
342:
343: The following instructions were contributed by a PCRE user.
344:
345: 1. Install the latest CMake version available from http://www.cmake.org/, and
346: ensure that cmake\bin is on your path.
347:
348: 2. Unzip (retaining folder structure) the PCRE source tree into a source
349: directory such as C:\pcre. You should ensure your local date and time
350: is not earlier than the file dates in your source dir if the release is
351: very new.
352:
353: 3. Create a new, empty build directory, preferably a subdirectory of the
354: source dir. For example, C:\pcre\pcre-xx\build.
355:
356: 4. Run cmake-gui from the Shell envirornment of your build tool, for example,
357: Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++.
358:
359: 5. Enter C:\pcre\pcre-xx and C:\pcre\pcre-xx\build for the source and build
360: directories, respectively.
361:
362: 6. Hit the "Configure" button.
363:
364: 7. Select the particular IDE / build tool that you are using (Visual
365: Studio, MSYS makefiles, MinGW makefiles, etc.)
366:
367: 8. The GUI will then list several configuration options. This is where
368: you can enable UTF-8 support or other PCRE optional features.
369:
370: 9. Hit "Configure" again. The adjacent "Generate" button should now be
371: active.
372:
373: 10. Hit "Generate".
374:
375: 11. The build directory should now contain a usable build system, be it a
376: solution file for Visual Studio, makefiles for MinGW, etc. Exit from
377: cmake-gui and use the generated build system with your compiler or IDE.
378: E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE
379: solution, select the desired configuration (Debug, or Release, etc.) and
380: build the ALL_BUILD project.
381:
382: 12. If during configuration with cmake-gui you've elected to build the test
383: programs, you can execute them by building the test project. E.g., for
384: MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
385: most recent build configuration is targeted by the tests. A summary of
386: test results is presented. Complete test output is subsequently
387: available for review in Testing\Temporary under your build dir.
388:
389:
390: USE OF RELATIVE PATHS WITH CMAKE ON WINDOWS
391:
392: A PCRE user comments as follows:
393:
394: I thought that others may want to know the current state of
395: CMAKE_USE_RELATIVE_PATHS support on Windows.
396:
397: Here it is:
398: -- AdditionalIncludeDirectories is only partially modified (only the
399: first path - see below)
400: -- Only some of the contained file paths are modified - shown below for
401: pcre.vcproj
402: -- It properly modifies
403:
404: I am sure CMake people can fix that if they want to. Until then one will
405: need to replace existing absolute paths in project files with relative
406: paths manually (e.g. from VS) - relative to project file location. I did
407: just that before being told to try CMAKE_USE_RELATIVE_PATHS. Not a big
408: deal.
409:
410: AdditionalIncludeDirectories="E:\builds\pcre\build;E:\builds\pcre\pcre-7.5;"
411: AdditionalIncludeDirectories=".;E:\builds\pcre\pcre-7.5;"
412:
413: RelativePath="pcre.h">
414: RelativePath="pcre_chartables.c">
415: RelativePath="pcre_chartables.c.rule">
416:
417:
418: TESTING WITH RUNTEST.BAT
419:
420: If configured with CMake, building the test project ("make test" or building
421: ALL_TESTS in Visual Studio) creates (and runs) pcre_test.bat (and depending
422: on your configuration options, possibly other test programs) in the build
423: directory. Pcre_test.bat runs RunTest.Bat with correct source and exe paths.
424:
425: For manual testing with RunTest.bat, provided the build dir is a subdirectory
426: of the source directory: Open command shell window. Chdir to the location
427: of your pcretest.exe and pcregrep.exe programs. Call RunTest.bat with
428: "..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
429:
430: To run only a particular test with RunTest.Bat provide a test number argument.
431:
432: Otherwise:
433:
434: 1. Copy RunTest.bat into the directory where pcretest.exe and pcregrep.exe
435: have been created.
436:
437: 2. Edit RunTest.bat to indentify the full or relative location of
438: the pcre source (wherein which the testdata folder resides), e.g.:
439:
440: set srcdir=C:\pcre\pcre-8.20
441:
442: 3. In a Windows command environment, chdir to the location of your bat and
443: exe programs.
444:
445: 4. Run RunTest.bat. Test outputs will automatically be compared to expected
446: results, and discrepancies will be identified in the console output.
447:
448: To independently test the just-in-time compiler, run pcre_jit_test.exe.
449: To test pcrecpp, run pcrecpp_unittest.exe, pcre_stringpiece_unittest.exe and
450: pcre_scanner_unittest.exe.
451:
452:
453: BUILDING UNDER WINDOWS WITH BCC5.5
454:
455: Michael Roy sent these comments about building PCRE under Windows with BCC5.5:
456:
457: Some of the core BCC libraries have a version of PCRE from 1998 built in,
458: which can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a
459: version mismatch. I'm including an easy workaround below, if you'd like to
460: include it in the non-unix instructions:
461:
462: When linking a project with BCC5.5, pcre.lib must be included before any of
463: the libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command
464: line.
465:
466:
467: BUILDING UNDER WINDOWS CE WITH VISUAL STUDIO 200x
468:
469: Vincent Richomme sent a zip archive of files to help with this process. They
470: can be found in the file "pcre-vsbuild.zip" in the Contrib directory of the FTP
471: site.
472:
473:
474: BUILDING PCRE ON OPENVMS
475:
476: Dan Mooney sent the following comments about building PCRE on OpenVMS. They
477: relate to an older version of PCRE that used fewer source files, so the exact
478: commands will need changing. See the current list of source files above.
479:
480: "It was quite easy to compile and link the library. I don't have a formal
481: make file but the attached file [reproduced below] contains the OpenVMS DCL
482: commands I used to build the library. I had to add #define
483: POSIX_MALLOC_THRESHOLD 10 to pcre.h since it was not defined anywhere.
484:
485: The library was built on:
486: O/S: HP OpenVMS v7.3-1
487: Compiler: Compaq C v6.5-001-48BCD
488: Linker: vA13-01
489:
490: The test results did not match 100% due to the issues you mention in your
491: documentation regarding isprint(), iscntrl(), isgraph() and ispunct(). I
492: modified some of the character tables temporarily and was able to get the
493: results to match. Tests using the fr locale did not match since I don't have
494: that locale loaded. The study size was always reported to be 3 less than the
495: value in the standard test output files."

539: BUILDING PCRE ON STRATUS OPENVOS
540:
541: These notes on the port of PCRE to VOS (lightly edited) were supplied by
542: Ashutosh Warikoo, whose email address has the local part awarikoo and the
543: domain nse.co.in. The port was for version 7.9 in August 2009.
544:
545: 1. Building PCRE
546:
547: I built pcre on OpenVOS Release 17.0.1at using GNU Tools 3.4a without any
548: problems. I used the following packages to build PCRE:
549:
550: ftp://ftp.stratus.com/pub/vos/posix/ga/posix.save.evf.gz
551:
552: Please read and follow the instructions that come with these packages. To start
553: the build of pcre, from the root of the package type:
554:
555: ./build.sh
556:
557: 2. Installing PCRE
558:
559: Once you have successfully built PCRE, login to the SysAdmin group, switch to
560: the root user, and type
561:
562: [ !create_dir (master_disk)>usr --if needed ]
563: [ !create_dir (master_disk)>usr>local --if needed ]
564: !gmake install
565:
566: This installs PCRE and its man pages into /usr/local. You can add
567: (master_disk)>usr>local>bin to your command search paths, or if you are in
568: BASH, add /usr/local/bin to the PATH environment variable.
569:
570: 4. Restrictions
571:
572: This port requires readline library optionally. However during the build I
573: faced some yet unexplored errors while linking with readline. As it was an
574: optional component I chose to disable it.
575:
576: 5. Known Problems
577:
578: I ran the test suite, but you will have to be your own judge of whether this
579: command, and this port, suits your purposes. If you find any problems that
580: appear to be related to the port itself, please let me know. Please see the
581: build.log file in the root of the package also.
