What is unclear about the following, quoting from http://www.gnu.org/software/autoconf/manual/html_node/Present-But-Cannot-Be-Compiled.html ? | The proper way the handle this case is using the fourth argument | (see Generic Headers): | | $ cat configure.ac | AC_INIT([Example], [1.0], [bug-example@xxxxxxxxxxx]) | AC_CHECK_HEADERS([number.h pi.h], [], [], | [[#if HAVE_NUMBER_H | # include <number.h> | #endif | ]]) > I am going to take a wild guess that > I replace this line from snprintfv.m4: > > AC_CHECK_HEADER(wchar.h) > > with this: > > AC_CHECK_HEADER([wchar.h], [], [], > [[#if HAVE_WCHAR_H > # include <wchar.h> > #endif > ]]) That wouldn't make any sense. A prerequisite header would typically be a different one. > Since reasonably modern system headers should be self-sufficient > (you should 'a been there in the seventies and eighties!!), Welcome back to the seventies and eighties then, I guess. > I really cannot imagine what prerequisite your "wchar.h" header > needs. FWIW, I don't either. The powerpc-apple-darwin8.7.0 system I tested on likes wchar.h just fine, without prerequisites. Hope that helps.
