##### http://autoconf-archive.cryp.to/ax_create_stdint_h.html # # 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). # # LAST MODIFICATION # # 2006-10-13 # # COPYLEFT # # Copyright (c) 2006 Guido U.
