| /* PCRE is written in Standard C, but there are a few non-standard things it |
| can cope with, allowing it to run on SunOS4 and other "close to standard" |
| systems. |
| |
| In environments that support the GNU autotools, config.h.in is converted into |
| config.h by the "configure" script. In environments that use CMake, |
| config-cmake.in is converted into config.h. If you are going to build PCRE "by |
| hand" without using "configure" or CMake, you should copy the distributed |
| config.h.generic to config.h, and edit the macro definitions to be the way you |
| need them. You must then add -DHAVE_CONFIG_H to all of your compile commands, |
| so that config.h is included at the start of every source. |
| |
| Alternatively, you can avoid editing by using -D on the compiler command line |
| to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H, |
| but if you do, default values will be taken from config.h for non-boolean |
| macros that are not defined on the command line. |
| |
| Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE8 should either be defined |
| (conventionally to 1) for TRUE, and not defined at all for FALSE. All such |
| macros are listed as a commented #undef in config.h.generic. Macros such as |
| MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are |
| surrounded by #ifndef/#endif lines so that the value can be overridden by -D. |
| |
| PCRE uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if |
| HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make |
| sure both macros are undefined; an emulation function will then be used. */]) |
