It may have to be this though, I don't know, you'd have to test (the AC_INCLUDES_DEFAULT prepends some standard headers). AC_CHECK_HEADERS([runetype.h wchar.h], [], [],[ AC_INCLUDES_DEFAULT #if HAVE_RUNETYPE_H # include <runetype.h> #endif ]) > and then when this runs: > # ---------------------------------------------------------------------- > # Checks for typedefs > # ---------------------------------------------------------------------- > AC_CHECK_TYPE(wint_t, unsigned int) > > "runetype.h" will have been added to the header list and "wint_t" > will be typedefed per that header, right? No, this will also need a fourth argument, exactly the same as above.
Then I would really recommend some autoconf changes: 1. Clarify for the dense among us what you are doing and why in the four argument examples 2. Indicate that the fourth argument isn't just for AC_CHECK_HEADER, but for AC_CHECK_whatever, too. 3. AC_CHECK_WINT_T, too, as this all seems a little over the top for your typical semi-neophyte. BTW, is there an abbreviated way of saying, ``add all the headers we've checked on to the list of "AC_INCLUDES_DEFAULT"?'' Because I would really prefer a macro that did an AC_CHECK_HEADER followed by appending it to the AC_INCLUDES_DEFAULT (if found,of course). That would actually eliminate the need for that fourth argument in our current examle. Thanks for your help.
