1dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])] 2dnl 3dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the 4dnl existence of an include file <stdint.h> that defines a set of 5dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older 6dnl installations will not provide this file, but some will have the 7dnl very same definitions in <inttypes.h>. In other enviroments we can 8dnl use the inet-types in <sys/types.h> which would define the typedefs 9dnl int8_t and u_int8_t respectivly. 10dnl 11dnl This macros will create a local "_stdint.h" or the headerfile given 12dnl as an argument. In many cases that file will just "#include 13dnl <stdint.h>" or "#include <inttypes.h>", while in other environments 14dnl it will provide the set of basic 'stdint's definitions/typedefs: 15dnl 16dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t 17dnl int_least32_t.. int_fast32_t.. intmax_t 18dnl 19dnl which may or may not rely on the definitions of other files, or 20dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each 21dnl type. 22dnl 23dnl if your header files require the stdint-types you will want to 24dnl create an installable file mylib-int.h that all your other 25dnl installable header may include. So if you have a library package 26dnl named "mylib", just use 27dnl 28dnl AX_CREATE_STDINT_H(mylib-int.h) 29dnl 30dnl in configure.ac and go to install that very header file in 31dnl Makefile.am along with the other headers (mylib.h) - and the 32dnl mylib-specific headers can simply use "#include <mylib-int.h>" to 33dnl obtain the stdint-types. 34dnl 35dnl Remember, if the system already had a valid <stdint.h>, the 36dnl generated file will include it directly. No need for fuzzy 37dnl HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled 38dnl its stdint.h for non-c99 compilation and the c99-mode is not the 39dnl default. Therefore this macro will not use the compiler's stdint.h 40dnl - please complain to the GCC developers). 41dnl 42dnl @category C 43dnl @author Guido U.
