| 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... | |
| 48 dnl | |
