|
| 16 |
|
|
dnl
|
| 17 |
|
|
dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
|
| 18 |
|
|
dnl existence of an include file <stdint.h> that defines a set of
|
| 19 |
|
|
dnl typedefs, especially uint8_t,int32_t,uintptr_t.
|
| 20 |
|
|
dnl Many older installations will not provide this file, but some will
|
| 21 |
|
|
dnl have the very same definitions in <inttypes.h>. In other enviroments
|
| 22 |
|
|
dnl we can use the inet-types in <sys/types.h> which would define the
|
| 23 |
|
|
dnl typedefs int8_t and u_int8_t respectivly.
|
| 24 |
|
|
dnl
|
| 25 |
|
|
dnl This macros will create a local "_stdint.h" or the headerfile given as
|
| 26 |
|
|
dnl an argument. In many cases that file will pick the definition from a
|
| 27 |
|
|
dnl "#include <stdint.h>" or "#include <inttypes.h>" statement, while
|
| 28 |
|
|
dnl in other environments it will provide the set of basic 'stdint's defined:
|
| 29 |
|
|
dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
|
| 30 |
|
|
dnl int_least32_t.. int_fast32_t.. intmax_t
|
| 31 |
|
|
dnl which may or may not rely on the definitions of other files.
|
| 32 |
|
|
dnl
|
| 33 |
|
|
dnl Sometimes the stdint.h or inttypes.h headers conflict with sys/types.h,
|
| 34 |
|
|
dnl so we test the headers together with sys/types.h and always include it
|
| 35 |
|
|
dnl into the generated header (to match the tests with the generated file).
|
| 36 |
|
|
dnl Hopefully this is not a big annoyance.
|
| 37 |
|
|
dnl
|
| 38 |
|
|
dnl If your installed header files require the stdint-types you will want to
|
| 39 |
|
|
dnl create an installable file mylib-int.h that all your other installable
|
| 40 |
|
|
dnl header may include. So, for a library package named "mylib", just use
|
| 41 |
|
|
dnl GCC_HEADER_STDINT(mylib-int.h)
|
| 42 |
|
|
dnl in configure.in and install that header file in Makefile.am along with
|
| 43 |
|
|
dnl the other headers (mylib.h). The mylib-specific headers can simply
|
| 44 |
|
|
dnl use "#include <mylib-int.h>" to obtain the stdint-types.
|
| 45 |
|
|
dnl
|
| 46 |
|
|
dnl Remember, if the system already had a valid <stdint.h>, the generated
|
| 47 |
|
|
dnl file will include it directly. No need for fuzzy HAVE_STDINT_H things...
