1/* src/config.h.in. Generated from configure.ac by autoheader. */ 2 3 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 defined 22(conventionally to 1) for TRUE, and not defined at all for FALSE. All such 23macros are listed as a commented #undef in config.h.generic. Macros such as 24MATCH_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. */ 30 31/* By default, the \R escape sequence matches any Unicode line ending 32 character or sequence of characters.
