| Compiling PCRE on non-Unix systems |
| ---------------------------------- |
| |
| If you want to compile PCRE for a non-Unix system, note that it consists |
| entirely of code written in Standard C, and so should compile successfully |
| on any machine with a Standard C compiler and library, using normal compiling |
| commands to do the following: |
| |
| (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. |
| |
| (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. |
| |
| (3) Compile dftables.c as a stand-alone program, and then run it with |
| the standard output sent to chartables.c. This generates a set of standard |
| character tables. |
| |
| (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 gets included by means of an |
| #include directive). |
| |
| (5) Similarly, compile pcreposix.c and link it as the pcreposix library. |
| |
| (6) Compile the test program pcretest.c. This needs the functions in the |
| pcre and pcreposix libraries when linking. |
| |
| (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. |
| |
| 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@technologist.com. 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). |
