|

dnl
|
|
|
|
|
dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
|
|
|
|
|
dnl existence of an include file <stdint.h> that defines a set of
|
|
|
|
|
dnl typedefs, especially uint8_t,int32_t,uintptr_t.
|
|
|
|
|
dnl Many older installations will not provide this file, but some will
|
|
|
|
|
dnl have the very same definitions in <inttypes.h>. In other enviroments
|
|
|
|
|
dnl we can use the inet-types in <sys/types.h> which would define the
|
|
|
|
|
dnl typedefs int8_t and u_int8_t respectivly.
|
|
|
|
|
dnl
|
|
|
|
|
dnl This macros will create a local "_stdint.h" or the headerfile given as
|
|
|
|
|
dnl an argument. In many cases that file will just "#include <stdint.h>"
|
|
|
|
|
dnl or "#include <inttypes.h>", while in other environments it will provide
|
|
|
|
|
dnl the set of basic 'stdint's definitions/typedefs:
|
|
|
|
|
dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
|
|
|
|
|
dnl int_least32_t.. int_fast32_t.. intmax_t
|
|
|
|
|
dnl which may or may not rely on the definitions of other files,
|
|
|
|
|
dnl or using the AC_CHECK_SIZEOF macro to determine the actual
|
|
|
|
|
dnl sizeof each type.
|
|
|
|
|
dnl
|
|
|
|
|
dnl if your header files require the stdint-types you will want to create an
|
|
|
|
|
dnl installable file mylib-int.h that all your other installable header
|
|
|
|
|
dnl may include. So if you have a library package named "mylib", just use
|
|
|
|
|
dnl AX_CREATE_STDINT_H(mylib-int.h)
|
|
|
|
|
dnl in configure.ac and go to install that very header file in Makefile.am
|
|
|
|
|
dnl along with the other headers (mylib.h) - and the mylib-specific headers
|
|
|
|
|
dnl can simply use "#include <mylib-int.h>" to obtain the stdint-types.
|
|
|
|
|
dnl
|
|
|
|
|
dnl Remember, if the system already had a valid <stdint.h>, the generated
|
|
|
|
|
dnl file will include it directly. No need for fuzzy HAVE_STDINT_H things...
