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). +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.
