4/* PCRE2 is written in Standard C, but there are a few non-standard things it
5can cope with, allowing it to run on SunOS4 and other "close to standard"
6systems.
7
8In environments that support the GNU autotools, config.h.in is converted into
9config.h by the "configure" script. In environments that use CMake,
10config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
11hand" without using "configure" or CMake, you should copy the distributed
12config.h.generic to config.h, and edit the macro definitions to be the way you
13need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
14so that config.h is included at the start of every source.
15
16Alternatively, you can avoid editing by using -D on the compiler command line
17to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
18but if you do, default values will be taken from config.h for non-boolean
19macros that are not defined on the command line.
20
21Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
22defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
23such macros are listed as a commented #undef in config.h.generic. Macros such
24as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
25surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
26
27PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
28HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
29sure both macros are undefined; an emulation function will then be used. */
