- # 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 environments we can use the inet-types in
- # <sys/types.h> which would define the typedefs int8_t and u_int8_t
- # respectively.
- #
- # 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 deliberately 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).
