dnl @synopsis AC_CREATE_PREFIX_CONFIG_H [(OUTPUT-HEADER [,PREFIX [,ORIG-HEADER]])]
|
|
dnl
|
|
dnl this is a new variant from ac_prefix_config_
|
|
dnl this one will use a lowercase-prefix if
|
|
dnl the config-define was starting with a lowercase-char, e.g.
|
|
dnl #define const or #define restrict or #define off_t
|
|
dnl (and this one can live in another directory, e.g. testpkg/config.h
|
|
dnl therefore I decided to move the output-header to be the first arg)
|
|
dnl
|
|
dnl takes the usual config.h generated header file; looks for each of
|
|
dnl the generated "#define SOMEDEF" lines, and prefixes the defined name
|
|
dnl (ie. makes it "#define PREFIX_SOMEDEF". The result is written to
|
|
dnl the output config.header file. The PREFIX is converted to uppercase
|
|
dnl for the conversions.
|
|
dnl
|
|
dnl default OUTPUT-HEADER = $PACKAGE-config.h
|
|
dnl default PREFIX = $PACKAGE
|
|
dnl default ORIG-HEADER, derived from OUTPUT-HEADER
|
|
dnl if OUTPUT-HEADER has a "/", use the basename
|
|
dnl if OUTPUT-HEADER has a "-", use the section after it.
|
|
dnl otherwise, just config.h
|
|
dnl
|
|
dnl In most cases, the configure.in will contain a line saying
|
|
dnl AC_CONFIG_HEADER(config.h)
|
|
dnl somewhere *before* AC_OUTPUT and a simple line saying
|
|
dnl AC_PREFIX_CONFIG_HEADER
|
|
dnl somewhere *after* AC_OUTPUT.
|
|
dnl
|
|
dnl example:
|
|
dnl AC_INIT(config.h.in) # config.h.in as created by "autoheader"
|
|
dnl AM_INIT_AUTOMAKE(testpkg, 0.1.1) # "#undef VERSION" and "PACKAGE"
|
|
dnl AM_CONFIG_HEADER(config.h) # in config.h.in
|
|
dnl AC_MEMORY_H # "#undef NEED_MEMORY_H"
|
|
dnl AC_C_CONST_H # "#undef const"
|
|
dnl AC_OUTPUT(Makefile) # creates the "config.h" now
|
|
dnl AC_CREATE_PREFIX_CONFIG_H # creates "testpkg-config.h"
|
|
dnl and the resulting "testpkg-config.h" contains lines like
|
|
dnl #ifndef TESTPKG_VERSION
|
|
dnl #define TESTPKG_VERSION "0.1.1"
|
|
dnl #endif
|
|
dnl #ifndef TESTPKG_NEED_MEMORY_H
|
|
dnl #define TESTPKG_NEED_MEMORY_H 1
|
|
dnl #endif
|
|
dnl #ifndef _testpkg_const
|
|
dnl #define _testpkg_const const
|
|
dnl #endif
|
|
dnl
|
|
dnl and this "testpkg-config.h" can be installed along with other
|
|
dnl header-files, which is most convenient when creating a shared
|
|
dnl library (that has some headers) where some functionality is
|
|
dnl dependent on the OS-features detected at compile-time. No
|
|
dnl need to invent some "testpkg-confdefs.h.in" manually. :-)
