/* PCRE is written in Standard C, but there are a few non-standard things it
|
| 430 |
can cope with, allowing it to run on SunOS4 and other "close to standard"
|
| 431 |
systems.
|
| 432 |
|
| 433 |
In environments that support the GNU autotools, config.h.in is converted into
|
| 434 |
config.h by the "configure" script. In environments that use CMake,
|
| 435 |
config-cmake.in is converted into config.h. If you are going to build PCRE "by
|
| 436 |
hand" without using "configure" or CMake, you should copy the distributed
|
| 437 |
config.h.generic to config.h, and edit the macro definitions to be the way you
|
| 438 |
need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
|
| 439 |
so that config.h is included at the start of every source.
|
| 440 |
|
| 441 |
Alternatively, you can avoid editing by using -D on the compiler command line
|
| 442 |
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
|
| 443 |
but if you do, default values will be taken from config.h for non-boolean
|
| 444 |
macros that are not defined on the command line.
|
| 445 |
|
| 446 |
Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE8 should either be defined
|
| 447 |
(conventionally to 1) for TRUE, and not defined at all for FALSE. All such
|
| 448 |
macros are listed as a commented #undef in config.h.generic. Macros such as
|
| 449 |
MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
|
| 450 |
surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
|
| 451 |
|
| 452 |
PCRE uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
|
| 453 |
HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
|
| 454 |
sure both macros are undefined; an emulation function will then be used. */])
