So, for a library package named "mylib", just use -dnl GCC_HEADER_STDINT(mylib-int.h) -dnl in configure.in and install that header file in Makefile.am along with -dnl the other headers (mylib.h). The mylib-specific headers can simply -dnl use "#include " to obtain the stdint-types. -dnl -dnl Remember, if the system already had a valid , the generated -dnl file will include it directly. No need for fuzzy HAVE_STDINT_H things... -dnl -dnl @author Guido Draheim , Paolo Bonzini +AC_DEFUN([GCC_STDINT_TYPES], +[AC_REQUIRE([AC_TYPE_INT8_T]) +AC_REQUIRE([AC_TYPE_INT16_T]) +AC_REQUIRE([AC_TYPE_INT32_T]) +AC_REQUIRE([AC_TYPE_INT64_T]) +AC_REQUIRE([AC_TYPE_INTMAX_T]) +AC_REQUIRE([AC_TYPE_INTPTR_T]) +AC_REQUIRE([AC_TYPE_UINT8_T]) +AC_REQUIRE([AC_TYPE_UINT16_T]) +AC_REQUIRE([AC_TYPE_UINT32_T]) +AC_REQUIRE([AC_TYPE_UINT64_T]) +AC_REQUIRE([AC_TYPE_UINTMAX_T]) +AC_REQUIRE([AC_TYPE_UINTPTR_T])]) AC_DEFUN([GCC_HEADER_STDINT], -[m4_define(_GCC_STDINT_H, m4_ifval($1, $1, _stdint.h)) +[AC_REQUIRE([GCC_STDINT_TYPES]) +AC_CHECK_TYPES([int_least32_t, int_fast32_t],,,[#include +#ifdef HAVE_STDINT_H +#include +#endif +#ifdef HAVE_INTTYPES_H +#include +#endif]) + +m4_define([_GCC_STDINT_H], m4_ifval($1, $1, _stdint.h)) +m4_if(m4_bmatch(m4_quote(/_GCC_STDINT_H), + /stdint\.h$, bad, + /inttypes\.h$, bad, ok), bad, + [m4_fatal([cannot overwrite ]m4_quote(_GCC_STDINT_H))]) -inttype_headers=`echo inttypes.h sys/inttypes.h $2 | sed -e 's/,/ /g'` - -acx_cv_header_stdint=stddef.h -acx_cv_header_stdint_kind="(already complete)" -for i in stdint.h $inttype_headers; do - unset ac_cv_type_uintptr_t - unset ac_cv_type_uintmax_t - unset ac_cv_type_int_least32_t - unset ac_cv_type_int_fast32_t - unset ac_cv_type_uint64_t - _AS_ECHO_N([looking for a compliant stdint.h in $i, ]) - AC_CHECK_TYPE(uintmax_t,[acx_cv_header_stdint=$i],continue,[#include -#include <$i>]) - AC_CHECK_TYPE(uintptr_t,,[acx_cv_header_stdint_kind="(mostly complete)"], [#include -#include <$i>]) - AC_CHECK_TYPE(int_least32_t,,[acx_cv_header_stdint_kind="(mostly complete)"], [#include -#include <$i>]) - AC_CHECK_TYPE(int_fast32_t,,[acx_cv_header_stdint_kind="(mostly complete)"], [#include -#include <$i>]) - AC_CHECK_TYPE(uint64_t,,[acx_cv_header_stdint_kind="(lacks uint64_t)"], [#include -#include <$i>]) - break -done -if test "$acx_cv_header_stdint" = stddef.h; then - acx_cv_header_stdint_kind="(lacks uintmax_t)" - for i in stdint.h $inttype_headers; do - unset ac_cv_type_uintptr_t - unset ac_cv_type_uint32_t - unset ac_cv_type_uint64_t - _AS_ECHO_N([looking for an incomplete stdint.h in $i, ]) - AC_CHECK_TYPE(uint32_t,[acx_cv_header_stdint=$i],continue,[#include -#include <$i>]) - AC_CHECK_TYPE(uint64_t,,,[#include -#include <$i>]) - AC_CHECK_TYPE(uintptr_t,,,[#include -#include <$i>]) - break - done -fi -if test "$acx_cv_header_stdint" = stddef.h; then - acx_cv_header_stdint_kind="(u_intXX_t style)" - for i in sys/types.h $inttype_headers; do - unset ac_cv_type_u_int32_t - unset ac_cv_type_u_int64_t - _AS_ECHO_N([looking for u_intXX_t types in $i, ]) - AC_CHECK_TYPE(u_int32_t,[acx_cv_header_stdint=$i],continue,[#include -#include <$i>]) - AC_CHECK_TYPE(u_int64_t,,,[#include -#include <$i>]) - break - done -fi -if test "$acx_cv_header_stdint" = stddef.h; then - acx_cv_header_stdint_kind="(using manual detection)" -fi - -test -z "$ac_cv_type_uintptr_t" && ac_cv_type_uintptr_t=no -test -z "$ac_cv_type_uint64_t" && ac_cv_type_uint64_t=no -test -z "$ac_cv_type_u_int64_t" && ac_cv_type_u_int64_t=no -test -z "$ac_cv_type_int_least32_t" && ac_cv_type_int_least32_t=no -test -z "$ac_cv_type_int_fast32_t" && ac_cv_type_int_fast32_t=no - -# ----------------- Summarize what we found so far - -AC_MSG_CHECKING([what to include in _GCC_STDINT_H]) - -case `AS_BASENAME(_GCC_STDINT_H)` in - stdint.h) AC_MSG_WARN([are you sure you want it there?]) ;; - inttypes.h) AC_MSG_WARN([are you sure you want it there?]) ;; - *) ;; -esac - -AC_MSG_RESULT($acx_cv_header_stdint $acx_cv_header_stdint_kind) - -# ----------------- done included file, check C basic types -------- - -# Lacking an uintptr_t?
