# 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).
