Hello, the text below seems to relly be a bug report with a proposed fix. So I take the liberty to forward it to the bug report address. Regards, Stepan Kasal ----- Forwarded message from "Gerrit P.

What is buggy is the autoconf test which is > just including resolv.h and not netinet/in.h to compile the test exe. This applies to the default test when calling AC_CHECK_HEADERS([resolv.h]) Workaround is to use s.th. like this in configure.ac: AC_CHECK_HEADERS([arpa/nameser.h netinet/in.h sys/socket.h sys/types.h]) AC_CHECK_HEADERS([resolv.h], [], [], [[#if HAVE_SYS_TYPES_H # include <sys/types.h> #endif #ifdef HAVE_NETINET_IN_H # include <netinet/in.h> /* inet_ functions / structs */ #endif #ifdef HAVE_ARPA_NAMESER_H # include <arpa/nameser.h> /* DNS HEADER struct */ #endif #ifdef HAVE_SYS_SOCKET_H # include <sys/socket.h> /* DNS HEADER struct */ #endif ]]) Anyway, there should be a macro which provides this functionity. -- =^..^= http://nyckelpiga.de/donate.html ----- End forwarded message ----- _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
