| Compiling PCRE on non-Unix systems |
| ---------------------------------- |
| |
| See below for comments on Cygwin or MinGW and OpenVMS usage. I (Philip Hazel) |
| have no knowledge of Windows or VMS sytems and how their libraries work. The |
| items in the PCRE Makefile that relate to anything other than Unix-like systems |
| have been contributed by PCRE users. There are some other comments and files in |
| the Contrib directory on the ftp site that you may find useful. See |
| |
| ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib |
| |
| If you want to compile PCRE for a non-Unix system (or perhaps, more strictly, |
| for a system that does not support "configure" and "make" files), note that |
| PCRE consists entirely of code written in Standard C, and so should compile |
| successfully on any system that has a Standard C compiler and library. |
| |
| |
| GENERIC INSTRUCTIONS |
| |
| The following are generic comments about building PCRE. The interspersed |
| indented commands are suggestions from Mark Tetrode as to which commands you |
| might use on a Windows system to build a static library. |
| |
| (1) Copy or rename the file config.in as config.h, and change the macros that |
| define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0. |
| Unfortunately, because of the way Unix autoconf works, the default setting has |
| to be 0. You may also want to make changes to other macros in config.h. In |
| particular, if you want to force a specific value for newline, you can define |
| the NEWLINE macro. The default is to use '\n', thereby using whatever value |
| your compiler gives to '\n'. |
| |
| rem Mark Tetrode's commands |
| copy config.in config.h |
| rem Use write, because notepad cannot handle UNIX files. Change values. |
| write config.h |
| |
| (2) Copy or rename the file pcre.in as pcre.h, and change the macro definitions |
| for PCRE_MAJOR, PCRE_MINOR, and PCRE_DATE near its start to the values set in |
| configure.in. |
| |
| rem Mark Tetrode's commands |
| copy pcre.in pcre.h |
| rem Read values from configure.in |
| write configure.in |
| rem Change values |
| write pcre.h |
| |
| (3) Compile dftables.c as a stand-alone program, and then run it with |
| the single argument "chartables.c". This generates a set of standard |
| character tables and writes them to that file. |
| |
| rem Mark Tetrode's commands |
| rem Compile & run |
| cl -DSUPPORT_UTF8 dftables.c |
| dftables.exe > chartables.c |
| |
| (4) Compile maketables.c, get.c, study.c and pcre.c and link them all |
| together into an object library in whichever form your system keeps such |
| libraries. This is the pcre library (chartables.c is included by means of an |
| #include directive). If your system has static and shared libraries, you may |
| have to do this once for each type. |
| |
| rem Mark Tetrode's commands, for a static library |
| rem Compile & lib |
| cl -DSUPPORT_UTF8 -DPOSIX_MALLOC_THRESHOLD=10 /c maketables.c get.c study.c pcre.c |
| lib /OUT:pcre.lib maketables.obj get.obj study.obj pcre.obj |
| |
| (5) Similarly, compile pcreposix.c and link it (on its own) as the pcreposix |
| library. |
| |
| rem Mark Tetrode's commands, for a static library |
| rem Compile & lib |
| cl -DSUPPORT_UTF8 -DPOSIX_MALLOC_THRESHOLD=10 /c pcreposix.c |
| lib /OUT:pcreposix.lib pcreposix.obj |
| |
| (6) Compile the test program pcretest.c. This needs the functions in the |
| pcre and pcreposix libraries when linking. |
| |
| rem Mark Tetrode's commands |
| rem compile & link |
| cl pcretest.c pcre.lib pcreposix.lib |
| |
| (7) Run pcretest on the testinput files in the testdata directory, and check |
| that the output matches the corresponding testoutput files. You must use the |
| -i option when checking testinput2. Note that the supplied files are in Unix |
| format, with just LF characters as line terminators. You may need to edit them |
| to change this if your system uses a different convention. |
| |
| rem Mark Tetrode's commands |
| rem Make a change, i.e. space, backspace, and save again - do this for all |
| rem to change UNIX to Win, \n to \n\r |
| write testoutput1 |
| write testoutput2 |
| write testoutput3 |
| write testoutput4 |
| write testoutput5 |
| pcretest testdata\testinput1 testdata\myoutput1 |
| windiff testdata\testoutput1 testdata\myoutput1 |
| pcretest -i testdata\testinput2 testdata\myoutput2 |
| windiff testdata\testoutput2 testdata\myoutput2 |
| pcretest testdata\testinput3 testdata\myoutput3 |
| windiff testdata\testoutput3 testdata\myoutput3 |
| pcretest testdata\testinput4 testdata\myoutput4 |
| windiff testdata\testoutput4 testdata\myoutput4 |
| pcretest testdata\testinput5 testdata\myoutput5 |
| windiff testdata\testoutput5 testdata\myoutput5 |
| |
| |
| FURTHER REMARKS |
| |
| If you have a system without "configure" but where you can use a Makefile, edit |
| Makefile.in to create Makefile, substituting suitable values for the variables |
| at the head of the file. |
| |
| Some help in building a Win32 DLL of PCRE in GnuWin32 environments was |
| contributed by Paul Sokolovsky. These environments are Mingw32 |
| (http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and CygWin |
| (http://sourceware.cygnus.com/cygwin/). Paul comments: |
| |
| For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get |
| pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically |
| linked pgrep and pcretest. If you have /bin/sh, run RunTest (three |
| main test go ok, locale not supported). |
| |
| Changes to do MinGW with autoconf 2.50 were supplied by Fred Cox |
| <sailorFred@yahoo.com>, who comments as follows: |
| |
| If you are using the PCRE DLL, the normal Unix style configure && make && |
| make check && make install should just work[*]. If you want to statically |
| link against the .a file, you must define PCRE_STATIC before including |
| pcre.h, otherwise the pcre_malloc and pcre_free exported functions will be |
| declared __declspec(dllimport), with hilarious results. See the configure.in |
| and pcretest.c for how it is done for the static test. |
| |
| Also, there will only be a libpcre.la, not a libpcreposix.la, as you |
| would expect from the Unix version. The single DLL includes the pcreposix |
| interface. |
| |
| [*] But note that the supplied test files are in Unix format, with just LF |
| characters as line terminators. You will have to edit them to change to CR LF |
| terminators. |
| |
| A script for building PCRE using Borland's C++ compiler for use with VPASCAL |
| was contributed by Alexander Tokarev. It is called makevp.bat. |
| |
| These are some further comments about Win32 builds from Mark Evans. They |
| were contributed before Fred Cox's changes were made, so it is possible that |
| they may no longer be relevant. |
| |
| "The documentation for Win32 builds is a bit shy. Under MSVC6 I |
| followed their instructions to the letter, but there were still |
| some things missing. |
| |
| (1) Must #define STATIC for entire project if linking statically. |
| (I see no reason to use DLLs for code this compact.) This of |
| course is a project setting in MSVC under Preprocessor. |
| |
| (2) Missing some #ifdefs relating to the function pointers |
| pcre_malloc and pcre_free. See my solution below. (The stubs |
| may not be mandatory but they made me feel better.)" |
| |
| ========================= |
| #ifdef _WIN32 |
| #include <malloc.h> |
| |
| void* malloc_stub(size_t N) |
| { return malloc(N); } |
| void free_stub(void* p) |
| { free(p); } |
| void *(*pcre_malloc)(size_t) = &malloc_stub; |
| void (*pcre_free)(void *) = &free_stub; |
| |
| #else |
| |
| void *(*pcre_malloc)(size_t) = malloc; |
| void (*pcre_free)(void *) = free; |
| |
| #endif |

| BUILDING PCRE ON OPENVMS |
| |
| Dan Mooney sent the following comments about building PCRE on OpenVMS: |
| |
| "It was quite easy to compile and link the library. I don't have a formal |
| make file but the attached file [reproduced below] contains the OpenVMS DCL |
| commands I used to build the library. I had to add #define |
| POSIX_MALLOC_THRESHOLD 10 to pcre.h since it was not defined anywhere. |
| |
| The library was built on: |
| O/S: HP OpenVMS v7.3-1 |
| Compiler: Compaq C v6.5-001-48BCD |
| Linker: vA13-01 |
| |
| The test results did not match 100% due to the issues you mention in your |
| documentation regarding isprint(), iscntrl(), isgraph() and ispunct(). I |
| modified some of the character tables temporarily and was able to get the |
| results to match. Tests using the fr locale did not match since I don't have |
| that locale loaded. The study size was always reported to be 3 less than the |
| value in the standard test output files." |
| |
| ========================= |
| $! This DCL procedure builds PCRE on OpenVMS |
| $! |
| $! I followed the instructions in the non-unix-use file in the distribution. |

| $! Arguments must be enclosed in quotes. |
| $ PCRETEST "-C" |
| $! Test results: |
| $! |
| $! The test results did not match 100%. The functions isprint(), iscntrl(), |
| $! isgraph() and ispunct() on OpenVMS must not produce the same results |
| $! as the system that built the test output files provided with the |
| $! distribution. |
| $! |
| $! The study size did not match and was always 3 less on OpenVMS. |
| $! |
| $! Locale could not be set to fr |
