1 nigel 41 Compiling PCRE on non-Unix systems
2     ----------------------------------
3    
4 nigel 75 See below for comments on Cygwin or MinGW and OpenVMS usage. I (Philip Hazel)
5     have no knowledge of Windows or VMS sytems and how their libraries work. The
6     items in the PCRE Makefile that relate to anything other than Unix-like systems
7     have been contributed by PCRE users. There are some other comments and files in
8     the Contrib directory on the ftp site that you may find useful. See

11 nigel 41
12 nigel 73 If you want to compile PCRE for a non-Unix system (or perhaps, more strictly,
13 nigel 75 for a system that does not support "configure" and "make" files), note that
14 nigel 87 the basic PCRE library consists entirely of code written in Standard C, and so
15     should compile successfully on any system that has a Standard C compiler and
16     library. The C++ wrapper functions are a separate issue (see below).

19 nigel 79 GENERIC INSTRUCTIONS FOR THE C LIBRARY
20 nigel 75
21     The following are generic comments about building PCRE. The interspersed
22     indented commands are suggestions from Mark Tetrode as to which commands you
23     might use on a Windows system to build a static library.
24    
25 nigel 93 (1) Copy or rename the file config.h.in as config.h, and change the macros that
26 nigel 43 define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0.
27     Unfortunately, because of the way Unix autoconf works, the default setting has
28 nigel 53 to be 0. You may also want to make changes to other macros in config.h. In
29     particular, if you want to force a specific value for newline, you can define
30     the NEWLINE macro. The default is to use '\n', thereby using whatever value
31     your compiler gives to '\n'.
32 nigel 41
33 nigel 75 rem Mark Tetrode's commands
34 nigel 93 copy config.h.in config.h
35 nigel 75 rem Use write, because notepad cannot handle UNIX files. Change values.
36     write config.h
37    
38 nigel 87 (2) Compile dftables.c as a stand-alone program, and then run it with
39 nigel 85 the single argument "pcre_chartables.c". This generates a set of standard
40 nigel 73 character tables and writes them to that file.
41 nigel 41
42 nigel 75 rem Mark Tetrode's commands
43     rem Compile & run
44 nigel 77 cl -DSUPPORT_UTF8 -DSUPPORT_UCP dftables.c
45 nigel 87 dftables.exe pcre_chartables.c
46 nigel 75
47 nigel 87 (3) Compile the following source files:
48 nigel 41
49 nigel 79 pcre_chartables.c
50     pcre_compile.c
51     pcre_config.c
52     pcre_dfa_exec.c
53     pcre_exec.c
54     pcre_fullinfo.c
55     pcre_get.c
56     pcre_globals.c
57     pcre_info.c
58     pcre_maketables.c
59 nigel 93 pcre_newline.c
60 nigel 79 pcre_ord2utf8.c
61     pcre_refcount.c
62     pcre_study.c
63     pcre_tables.c
64     pcre_try_flipped.c
65 nigel 87 pcre_ucp_searchfuncs.c
66 nigel 79 pcre_valid_utf8.c
67     pcre_version.c
68     pcre_xclass.c
69    
70     and link them all together into an object library in whichever form your system
71     keeps such libraries. This is the pcre C library. If your system has static and
72     shared libraries, you may have to do this once for each type.
73    
74     rem These comments are out-of-date, referring to a previous release which
75     rem had fewer source files. Replace with the file names from above.
76 nigel 75 rem Mark Tetrode's commands, for a static library
77     rem Compile & lib
78 nigel 77 cl -DSUPPORT_UTF8 -DSUPPORT_UCP -DPOSIX_MALLOC_THRESHOLD=10 /c maketables.c get.c study.c pcre.c
79 nigel 75 lib /OUT:pcre.lib maketables.obj get.obj study.obj pcre.obj
80    
81 nigel 87 (4) Similarly, compile pcreposix.c and link it (on its own) as the pcreposix
82 nigel 73 library.
83 nigel 41
84 nigel 75 rem Mark Tetrode's commands, for a static library
85     rem Compile & lib
86 nigel 77 cl -DSUPPORT_UTF8 -DSUPPORT_UCP -DPOSIX_MALLOC_THRESHOLD=10 /c pcreposix.c
87 nigel 75 lib /OUT:pcreposix.lib pcreposix.obj
88    
89 nigel 87 (5) Compile the test program pcretest.c. This needs the functions in the
90 nigel 41 pcre and pcreposix libraries when linking.
91    
92 nigel 75 rem Mark Tetrode's commands
93     rem compile & link
94 nigel 77 cl /F0x400000 pcretest.c pcre.lib pcreposix.lib
95 nigel 75
96 nigel 87 (6) Run pcretest on the testinput files in the testdata directory, and check
97 nigel 93 that the output matches the corresponding testoutput files. Note that the
98     supplied files are in Unix format, with just LF characters as line terminators.
99     You may need to edit them to change this if your system uses a different
100     convention.
101 nigel 41
102 nigel 75 rem Mark Tetrode's commands
103     pcretest testdata\testinput1 testdata\myoutput1
104     windiff testdata\testoutput1 testdata\myoutput1

113 nigel 77 pcretest testdata\testinput6 testdata\myoutput6
114     windiff testdata\testoutput6 testdata\myoutput6
115 nigel 75
116 nigel 79 Note that there are now three more tests (7, 8, 9) that did not exist when Mark
117     wrote those comments. The test the new pcre_dfa_exec() function.
118 nigel 75
119 nigel 87 (7) If you want to use the pcregrep command, compile and link pcregrep.c; it
120     uses only the basic PCRE library.
121 nigel 79
122 nigel 87
123 nigel 79 THE C++ WRAPPER FUNCTIONS
124    
125     The PCRE distribution now contains some C++ wrapper functions and tests,
126     contributed by Google Inc. On a system that can use "configure" and "make",
127     the functions are automatically built into a library called pcrecpp. It should
128     be straightforward to compile the .cc files manually on other systems. The
129     files called xxx_unittest.cc are test programs for each of the corresponding
130     xxx.cc files.
131    
132    
133 nigel 75 FURTHER REMARKS
134    
135 nigel 41 If you have a system without "configure" but where you can use a Makefile, edit
136     Makefile.in to create Makefile, substituting suitable values for the variables
137     at the head of the file.
138    
139 nigel 93 Michael Roy sent these comments about building PCRE under Windows with BCC5.5:
140    
141     Some of the core BCC libraries have a version of PCRE from 1998 built in,
142     which can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a
143     version mismatch. I'm including an easy workaround below, if you'd like to
144     include it in the non-unix instructions:
145    
146     When linking a project with BCC5.5, pcre.lib must be included before any of
147     the libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command
148     line.
149    
150 nigel 41 Some help in building a Win32 DLL of PCRE in GnuWin32 environments was
151 nigel 63 contributed by Paul Sokolovsky. These environments are Mingw32
152     (http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and CygWin
153     (http://sourceware.cygnus.com/cygwin/). Paul comments:
154 nigel 41
155     For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get
156     pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically
157     linked pgrep and pcretest. If you have /bin/sh, run RunTest (three
158     main test go ok, locale not supported).
159    
160 nigel 63 Changes to do MinGW with autoconf 2.50 were supplied by Fred Cox
161     <sailorFred@yahoo.com>, who comments as follows:
162    
163     If you are using the PCRE DLL, the normal Unix style configure && make &&
164     make check && make install should just work[*]. If you want to statically
165     link against the .a file, you must define PCRE_STATIC before including
166     pcre.h, otherwise the pcre_malloc and pcre_free exported functions will be
167     declared __declspec(dllimport), with hilarious results. See the configure.in
168     and pcretest.c for how it is done for the static test.
169    
170     Also, there will only be a libpcre.la, not a libpcreposix.la, as you
171     would expect from the Unix version. The single DLL includes the pcreposix
172     interface.
173    
174     [*] But note that the supplied test files are in Unix format, with just LF
175     characters as line terminators. You will have to edit them to change to CR LF
176     terminators.
177    
178     A script for building PCRE using Borland's C++ compiler for use with VPASCAL
179     was contributed by Alexander Tokarev. It is called makevp.bat.
180    
181     These are some further comments about Win32 builds from Mark Evans. They
182     were contributed before Fred Cox's changes were made, so it is possible that
183     they may no longer be relevant.
184    
185 nigel 73 "The documentation for Win32 builds is a bit shy. Under MSVC6 I
186 nigel 63 followed their instructions to the letter, but there were still
187     some things missing.
188    
189     (1) Must #define STATIC for entire project if linking statically.
190     (I see no reason to use DLLs for code this compact.) This of
191     course is a project setting in MSVC under Preprocessor.
192    
193     (2) Missing some #ifdefs relating to the function pointers
194     pcre_malloc and pcre_free. See my solution below. (The stubs
195 nigel 73 may not be mandatory but they made me feel better.)"
196 nigel 63
197     =========================
198     #ifdef _WIN32
199     #include <malloc.h>
200    
201     void* malloc_stub(size_t N)
202     { return malloc(N); }
203     void free_stub(void* p)
204     { free(p); }
205     void *(*pcre_malloc)(size_t) = &malloc_stub;
206     void (*pcre_free)(void *) = &free_stub;
207    
208     #else
209    
210     void *(*pcre_malloc)(size_t) = malloc;
211     void (*pcre_free)(void *) = free;
212    
213     #endif

216 nigel 75
217     BUILDING PCRE ON OPENVMS
218    
219 nigel 79 Dan Mooney sent the following comments about building PCRE on OpenVMS. They
220     relate to an older version of PCRE that used fewer source files, so the exact
221     commands will need changing. See the current list of source files above.
222 nigel 75
223     "It was quite easy to compile and link the library. I don't have a formal
224     make file but the attached file [reproduced below] contains the OpenVMS DCL
225     commands I used to build the library. I had to add #define
226     POSIX_MALLOC_THRESHOLD 10 to pcre.h since it was not defined anywhere.
227    
228     The library was built on:
229     O/S: HP OpenVMS v7.3-1
230     Compiler: Compaq C v6.5-001-48BCD
231     Linker: vA13-01
232    
233     The test results did not match 100% due to the issues you mention in your
234     documentation regarding isprint(), iscntrl(), isgraph() and ispunct(). I
235     modified some of the character tables temporarily and was able to get the
236     results to match. Tests using the fr locale did not match since I don't have
237     that locale loaded. The study size was always reported to be 3 less than the
238     value in the standard test output files."
