dnl Process this file with autoconf to produce a configure script.
|
||||
|
||||
dnl NOTE FOR MAINTAINERS: Do not use minor version numbers 08 or 09 because
|
||||
dnl the leading zeros may cause them to be treated as invalid octal constants
|
||||
dnl if a PCRE user writes code that uses PCRE_MINOR as a number. There is now
|
||||
dnl a check further down that throws an error if 08 or 09 are used.
|
||||
|
||||
dnl The PCRE_PRERELEASE feature is for identifying release candidates. It might
|
||||
dnl be defined as -RC2, for example. For real releases, it should be empty.

|
||||
config-cmake.in is converted into config.h. If you are going to build PCRE "by
|
||||
hand" without using "configure" or CMake, you should copy the distributed
|
||||
config.h.generic to config.h, and edit the macro definitions to be the way you
|
||||
need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
|
||||
so that config.h is included at the start of every source.
|
||||
|
||||
Alternatively, you can avoid editing by using -D on the compiler command line
|
||||
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
|
||||
but if you do, default values will be taken from config.h for non-boolean
|
||||
macros that are not defined on the command line.
|
||||
|
||||
Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE8 should either be defined
|
||||
(conventionally to 1) for TRUE, and not defined at all for FALSE. All such
|
||||
macros are listed as a commented #undef in config.h.generic. Macros such as
|
||||
MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
|
||||
surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
|
||||
|
||||
PCRE uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
|
||||
HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
|
||||
sure both macros are undefined; an emulation function will then be used. */])
