Many older 12# installations will not provide this file, but some will have the 13# very same definitions in <inttypes.h>. In other enviroments we can 14# use the inet-types in <sys/types.h> which would define the typedefs 15# int8_t and u_int8_t respectivly. 16# 17# This macros will create a local "_stdint.h" or the headerfile given 18# as an argument. In many cases that file will just "#include 19# <stdint.h>" or "#include <inttypes.h>", while in other environments 20# it will provide the set of basic 'stdint's definitions/typedefs: 21# 22# int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t 23# int_least32_t.. int_fast32_t.. intmax_t 24# 25# which may or may not rely on the definitions of other files, or 26# using the AC_CHECK_SIZEOF macro to determine the actual sizeof each 27# type. 28# 29# if your header files require the stdint-types you will want to 30# create an installable file mylib-int.h that all your other 31# installable header may include. So if you have a library package 32# named "mylib", just use 33# 34# AX_CREATE_STDINT_H(mylib-int.h) 35# 36# in configure.ac and go to install that very header file in 37# Makefile.am along with the other headers (mylib.h) - and the 38# mylib-specific headers can simply use "#include <mylib-int.h>" to 39# obtain the stdint-types. 40# 41# Remember, if the system already had a valid <stdint.h>, the 42# generated file will include it directly. No need for fuzzy 43# HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled 44# its stdint.h for non-c99 compilation and the c99-mode is not the 45# default. Therefore this macro will not use the compiler's stdint.h 46# - please complain to the GCC developers). 47# 48# LAST MODIFICATION 49# 50# 2007-06-27 51# 52# COPYLEFT 53# 54# Copyright (c) 2007 Guido U.
