1.1.1.4 misho 4: /* PCRE is written in Standard C, but there are a few non-standard things it
5: can cope with, allowing it to run on SunOS4 and other "close to standard"
6: systems.
7:
8: In environments that support the GNU autotools, config.h.in is converted into
9: config.h by the "configure" script. In environments that use CMake,
10: config-cmake.in is converted into config.h. If you are going to build PCRE "by
11: hand" without using "configure" or CMake, you should copy the distributed
12: config.h.generic to config.h, and edit the macro definitions to be the way you
13: need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
14: so that config.h is included at the start of every source.
1.1 misho 15:
16: Alternatively, you can avoid editing by using -D on the compiler command line
1.1.1.4 misho 17: to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
18: but if you do, default values will be taken from config.h for non-boolean
19: macros that are not defined on the command line.
20:
21: Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE8 should either be defined
22: (conventionally to 1) for TRUE, and not defined at all for FALSE. All such
23: macros are listed as a commented #undef in config.h.generic. Macros such as
24: MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
25: surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
26:
27: PCRE uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
28: HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
29: sure both macros are undefined; an emulation function will then be used. */
1.1 misho 30:
31: /* By default, the \R escape sequence matches any Unicode line ending
1.1.1.4 misho 32: character or sequence of characters. If BSR_ANYCRLF is defined (to any
33: value), this is changed so that backslash-R matches only CR, LF, or CRLF.
34: The build-time default can be overridden by the user of PCRE at runtime. */

36:
37: /* If you are compiling for a system that uses EBCDIC instead of ASCII
1.1.1.4 misho 38: character codes, define this macro to any value. You must also edit the
39: NEWLINE macro below to set a suitable EBCDIC newline, commonly 21 (0x15).
40: On systems that can use "configure" or CMake to set EBCDIC, NEWLINE is
41: automatically adjusted. When EBCDIC is set, PCRE assumes that all input
42: strings are in EBCDIC. If you do not define this macro, PCRE will assume
43: input strings are ASCII or UTF-8/16/32 Unicode. It is not possible to build
44: a version of PCRE that supports both EBCDIC and UTF-8/16/32. */
