23  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.h.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.h.in config.h  
   rem Use write, because notepad cannot handle UNIX files. Change values.  
   write config.h  
   
 (2) Compile dftables.c as a stand-alone program, and then run it with  
 the single argument "pcre_chartables.c". This generates a set of standard  
 character tables and writes them to that file.  
   
   rem Mark Tetrode's commands  
   rem Compile & run  
   cl -DSUPPORT_UTF8 -DSUPPORT_UCP dftables.c  
   dftables.exe pcre_chartables.c  
   
 (3) Compile the following source files:  
   
   pcre_chartables.c  
   pcre_compile.c  
   pcre_config.c  
   pcre_dfa_exec.c  
   pcre_exec.c  
   pcre_fullinfo.c  
   pcre_get.c  
   pcre_globals.c  
   pcre_info.c  
   pcre_maketables.c  
   pcre_newline.c  
   pcre_ord2utf8.c  
   pcre_refcount.c  
   pcre_study.c  
   pcre_tables.c  
   pcre_try_flipped.c  
   pcre_ucp_searchfuncs.c  
   pcre_valid_utf8.c  
   pcre_version.c  
   pcre_xclass.c  
   
 and link them all together into an object library in whichever form your system  
 keeps such libraries. This is the pcre C library. If your system has static and  
 shared libraries, you may have to do this once for each type.  
   
   rem These comments are out-of-date, referring to a previous release which  
   rem had fewer source files. Replace with the file names from above.  
   rem Mark Tetrode's commands, for a static library  
   rem Compile & lib  
   cl -DSUPPORT_UTF8 -DSUPPORT_UCP -DPOSIX_MALLOC_THRESHOLD=10 /c maketables.c get.c study.c pcre.c  
   lib /OUT:pcre.lib maketables.obj get.obj study.obj pcre.obj  
   
 (4) Similarly, compile pcreposix.c and link it (on its own) as the pcreposix  
 library.  
   
   rem Mark Tetrode's commands, for a static library

   cl -DSUPPORT_UTF8 -DSUPPORT_UCP -DPOSIX_MALLOC_THRESHOLD=10 /c pcreposix.c  
   lib /OUT:pcreposix.lib pcreposix.obj  
   
 (5) Compile the test program pcretest.c. This needs the functions in the  
 pcre and pcreposix libraries when linking.  
   
   rem Mark Tetrode's commands  
   rem compile & link  
   cl /F0x400000 pcretest.c pcre.lib pcreposix.lib  
   
 (6) Run pcretest on the testinput files in the testdata directory, and check  
 that the output matches the corresponding testoutput files. Note that the  
 supplied files are in Unix format, with just LF characters as line terminators.  
 You may need to edit them to change this if your system uses a different  
 convention.  
   
   rem Mark Tetrode's commands  
   pcretest testdata\testinput1 testdata\myoutput1  
   windiff testdata\testoutput1 testdata\myoutput1  
   pcretest -i testdata\testinput2 testdata\myoutput2  
   windiff testdata\testoutput2 testdata\myoutput2  
   pcretest testdata\testinput3 testdata\myoutput3  
   windiff testdata\testoutput3 testdata\myoutput3  
   pcretest testdata\testinput4 testdata\myoutput4  
   windiff testdata\testoutput4 testdata\myoutput4  
   pcretest testdata\testinput5 testdata\myoutput5  
   windiff testdata\testoutput5 testdata\myoutput5  
   pcretest testdata\testinput6 testdata\myoutput6  
   windiff testdata\testoutput6 testdata\myoutput6  
24    
25  Note that there are now three more tests (7, 8, 9) that did not exist when Mark  (1) Copy or rename the file config.h.generic as config.h, and edit the macro
26  wrote those comments. The test the new pcre_dfa_exec() function.      settings that it contains to whatever is appropriate for your environment.
27        In particular, if you want to force a specific value for newline, you can
28        define the NEWLINE macro.
29    
30        An alternative approach is not to edit config.h, but to use -D on the
31        compiler command line to make any changes that you need.
32    
33    (2) Copy or rename the file pcre.h.generic to pcre.h.
34    
35    (3) Compile dftables.c as a stand-alone program, and then run it with
36        the single argument "pcre_chartables.c". This generates a set of standard
37        character tables and writes them to that file.
38    
39    (4) Compile the following source files:
40    
41          pcre_chartables.c
42          pcre_compile.c
43          pcre_config.c
44          pcre_dfa_exec.c

62        Now link them all together into an object library in whichever form your
63        system keeps such libraries. This is the basic PCRE C library. If your
64        system has static and shared libraries, you may have to do this once for
65        each type.
