This is recommended practice as per https://www.gnu.org/software/automake/manual/html_node/Local-Macros.html. It fixes the problem that arose when one of the maintainers could not build LibVNCServer after https://github.com/LibVNC/libvncserver/pull/38 was merged. Symptoms included checking whether make sets $(MAKE)... yes ./configure: line 2481: syntax error near unexpected token `rfb/rfbconfig.h' ./configure: line 2481: `AX_PREFIX_CONFIG_H(rfb/rfbconfig.h)' until autoconf-archive was installed (which was a previously unmentioned requirement for Pull Request #38) – this is not always an option, in particular when the project needs to be built using a system-wide autoconf installation that cannot be modified easily by the developer.pull/1/head

# SYNOPSIS
|
||||
#
|
||||
# AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
|
||||
# existence of an include file <stdint.h> that defines a set of typedefs,
|
||||
# especially uint8_t,int32_t,uintptr_t. Many older installations will not
|
||||
# provide this file, but some will have the very same definitions in
|
||||
# <inttypes.h>. In other enviroments we can use the inet-types in
|
||||
# <sys/types.h> which would define the typedefs int8_t and u_int8_t
|
||||
# respectivly.
|
||||
#
|
||||
# This macros will create a local "_stdint.h" or the headerfile given as
|
||||
# an argument. In many cases that file will just "#include <stdint.h>" or
|
||||
# "#include <inttypes.h>", while in other environments it will provide the
|
||||
# set of basic 'stdint's definitions/typedefs:
|
||||
#
|
||||
# int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
|
||||
# int_least32_t.. int_fast32_t.. intmax_t
|
||||
#
|
||||
# which may or may not rely on the definitions of other files, or using
|
||||
# the AC_CHECK_SIZEOF macro to determine the actual sizeof each type.
|
||||
#
|
||||
# if your header files require the stdint-types you will want to create an
|
||||
# installable file mylib-int.h that all your other installable header may
|
||||
# include. So if you have a library package named "mylib", just use
|
||||
#
|
||||
# AX_CREATE_STDINT_H(mylib-int.h)
|
||||
#
|
||||
# in configure.ac and go to install that very header file in Makefile.am
|
||||
# along with the other headers (mylib.h) - and the mylib-specific headers
|
||||
# can simply use "#include <mylib-int.h>" to obtain the stdint-types.
|
||||
#
|
||||
# Remember, if the system already had a valid <stdint.h>, the generated
|
||||
# file will include it directly. No need for fuzzy HAVE_STDINT_H things...
|
||||
# (oops, GCC 4.2.x has deliberatly disabled its stdint.h for non-c99
|
||||
# compilation and the c99-mode is not the default. Therefore this macro
|
||||
# will not use the compiler's stdint.h - please complain to the GCC
|
||||
# developers).

# SYNOPSIS
|
||||
#
|
||||
# AX_PREFIX_CONFIG_H [(OUTPUT-HEADER [,PREFIX [,ORIG-HEADER]])]
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Generate an installable config.h.
|
||||
#
|
||||
# A package should not normally install its config.h as a system header,
|
||||
# but if it must, this macro can be used to avoid namespace pollution by
|
||||
# making a copy of config.h with a prefix added to all the macro names.
|
||||
#
|
||||
# Each "#define SOMEDEF" line of the configuration header has the given
|
||||
# prefix added, in the same case as the first character of the macro name.
|
||||
#
|
||||
# Defaults:
|
||||
#
|
||||
# OUTPUT-HEADER = $PACKAGE-config.h
|
||||
# PREFIX = $PACKAGE
|
||||
# ORIG-HEADER, from AM_CONFIG_HEADER(config.h)
|
||||
#
|
||||
# Your configure.ac script should contain both macros in this order.
|
||||
#
|
||||
# Example:
|
||||
#
|
||||
# AC_INIT(config.h.in) # config.h.in as created by "autoheader"
|
||||
# AM_INIT_AUTOMAKE(testpkg, 0.1.1) # makes #undef VERSION and PACKAGE
|
||||
# AM_CONFIG_HEADER(config.h) # prep config.h from config.h.in
|
||||
# AX_PREFIX_CONFIG_H(mylib/_config.h) # prep mylib/_config.h from it..
|
||||
# AC_MEMORY_H # makes "#undef NEED_MEMORY_H"
|
||||
# AC_C_CONST_H # makes "#undef const"
|
||||
# AC_OUTPUT(Makefile) # creates the "config.h" now
|
||||
# # and also mylib/_config.h
|
||||
#
|
||||
# If the argument to AX_PREFIX_CONFIG_H would have been omitted then the
|
||||
# default output file would have been called simply "testpkg-config.h",
|
||||
# but even under the name "mylib/_config.h" it contains prefix-defines
|
||||
# like
|
||||
#
|
||||
# #ifndef TESTPKG_VERSION
|
||||
# #define TESTPKG_VERSION "0.1.1"

|

||||
# #define TESTPKG_NEED_MEMORY_H 1
|
||||
# #endif
|
||||
# #ifndef _testpkg_const
|
||||
# #define _testpkg_const _const
|
||||
# #endif
|
||||
#
|
||||
# and this "mylib/_config.h" can be installed along with other header
|
||||
# files, which is most convenient when creating a shared library (that has
|
||||
# some headers) whose functionality depends on features detected at
|
||||
# compile-time. No need to invent some "mylib-confdefs.h.in" manually.
|
||||
#
|
||||
# Note that some AC_DEFINEs that end up in the config.h file are actually
|
||||
# self-referential - e.g. AC_C_INLINE, AC_C_CONST, and the AC_TYPE_OFF_T
|
||||
# say that they "will define inline|const|off_t if the system does not do
|
||||
# it by itself". You might want to clean up about these - consider an
|
||||
# extra mylib/conf.h that reads something like:
|
||||
#
|
||||
# #include <mylib/_config.h>
|
||||
# #ifndef _testpkg_const
|
||||
# #define _testpkg_const const
|
||||
# #endif
|
||||
#
|
||||
# and then start using _testpkg_const in the header files. That is also a
|
||||
# good thing to differentiate whether some library-user has starting to
|
||||
# take up with a different compiler, so perhaps it could read something
|
||||
# like this:
|
||||
#
|
||||
# #ifdef _MSC_VER
|
||||
# #include <mylib/_msvc.h>
|
||||
# #else
|
||||
# #include <mylib/_config.h>
|
||||
# #endif
|
||||
# #ifndef _testpkg_const
|
||||
# #define _testpkg_const const
