5 # AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
9 # the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
10 # existence of an include file <stdint.h> that defines a set of
11 # typedefs, especially uint8_t,int32_t,uintptr_t. 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.
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:
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
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
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
34 # AX_CREATE_STDINT_H(mylib-int.h)
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.
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).
