22  The following are generic comments about building PCRE. The interspersed  The following are generic comments about building the PCRE C library "by hand".
 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

24  (3) Compile dftables.c as a stand-alone program, and then run it with  (1) Copy or rename the file config.h.generic as config.h, and edit the macro

26  character tables and writes them to that file.      In particular, if you want to force a specific value for newline, you can
27        define the NEWLINE macro.
28    
29        An alternative approach is not to edit config.h, but to use -D on the
30        compiler command line to make any changes that you need.

99    BUILDING UNDER WINDOWS WITH BCC5.5
100    
101    Michael Roy sent these comments about building PCRE under Windows with BCC5.5:
102    
103      Some of the core BCC libraries have a version of PCRE from 1998 built in,
104      which can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a
105      version mismatch. I'm including an easy workaround below, if you'd like to
106      include it in the non-unix instructions:
107    
108      When linking a project with BCC5.5, pcre.lib must be included before any of
109      the libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command
110      line.
