| # 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). |
