# AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]

# DESCRIPTION
|
|
8 |
#
|
|
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.
|
|
16 |
#
|
|
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:
|
|
21 |
#
|
|
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
|
|
24 |
#
|
|
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
|
|
27 |
# type.
|
|
28 |
#
|
|
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
|
|
33 |
#
|
|
34 |
# AX_CREATE_STDINT_H(mylib-int.h)
|
|
35 |
#
|
|
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.
|
|
40 |
#
|
|
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).
