# 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). |
