In environments that use CMake, 11 config-cmake.in is converted into config.h. If you are going to build PCRE2 "by 12 hand" without using "configure" or CMake, you should copy the distributed 13 config.h.generic to config.h, and edit the macro definitions to be the way you 14 need them. You must then add -DHAVE_CONFIG_H to all of your compile commands, 15 so that config.h is included at the start of every source. 16 17 Alternatively, you can avoid editing by using -D on the compiler command line 18 to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H, 19 but if you do, default values will be taken from config.h for non-boolean 20 macros that are not defined on the command line. 21 22 Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be 23 defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All 24 such macros are listed as a commented #undef in config.h.generic. Macros such 25 as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are 26 surrounded by #ifndef/#endif lines so that the value can be overridden by -D. 27 28 PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if 29 HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make 30 sure both macros are undefined; an emulation function will then be used. */ 31 32 /* By default, the \R escape sequence matches any Unicode line ending 33 character or sequence of characters.
