# PCRE Command Line Makefile for Microsoft Visual Studio 
# Contributed by Tom Fortmann on April 25th, 2011
#
# Building PCRE library on Windows with Visual Studio 2005:
#
# 1) copy config.h.generic config.h
# 2) copy pcre.h.generic pcre.h
# 3) Edit config.h with the following changes.  These I believe are required
#    for all builds under Visual Studio.
#
#     #undef HAVE_DIRENT_H
#     #undef HAVE_INTTYPES_H
#     #undef HAVE_STDINT_H
#     #undef HAVE_UNISTD_H
#     #define HAVE_WINDOWS_H 1
#     #define SUPPORT_UCP
#     #define SUPPORT_UTF8
#
# 4) Update this make file as needed - this was based on the 8.12 release.
# 5) Run 'nmake -f winpcre.mak [DEBUG=1] [DLLBUILD=1] clean all test'
#
# Notes:
#
# I'm building from a DOS command line using nmake and the Visual Studio 2005
# compiler.  Other Windows compilers, and other releases of Visual Studio may
# require additional changes to config.h and this make file.
#
# A 'DEBUG=1' definition may be added to the nmake command line to add debugging
# options to the cl command line.  For release builds I have a fairly safe /Ot
# (favor speed) optimization enabled.  You can change this to suite your needs.
#
# For my application I just wanted a static library, but you can add the  
# 'DLLBUILD=1' definition to the nmake command line to build a DLL library.
# However, be aware that the locale test (3) on my system is failing with the
# DLL build!  I strongly suspect this is a Windows and/or environment issue and 
# NOT a code bug.  Unfortunately, I have not had a chance to chase this one down.
#
# By default the match() function is highly recursive.  On my system pcretest 
# required an 8mb stack to pass testinput2 without a stack overflow exception.
# So, you either need to increase the stack size by adding a /F8000000 to the 
# cl command, or disable recursion with the /DNO_RECURSE option.  For my 
# application disabling recursion was a simple acceptable solution, but you can 
# change this below.
# 
# And a few disclaimers...
#
# First I'm a UNIX guy living in a Windows world - which is evident by the 
# number of times I've cursored nmake while writing this make file.  
# So, please be kind as you cleanup/fix things.  
# 
# I'm contributing this make file in the hopes that it will save the next 
# developer some time, but it is provided without any explicit or implied
# warranty.  Please use it as you see fit.  
#
# If you update this file please don't misrepresent it as my original work.  
# Please remove my name from above and/or add your own attribution.
#
# Thanks and enjoy!
