From 2b43bf231c3004efaef96f2b85d0e0f4cf6a1ea1 Mon Sep 17 00:00:00 2001 From: Denis Ovsienko Date: Thu, 14 Jul 2011 16:30:08 +0400 Subject: configure: fix FreeBSD header detection (BZ#408) This change is based on Xavier Beaudouin's patch (which fixes detection of 3 config.h macros on FreeBSD without any impact to Linux build of Quagga) and FreeBSD port patch (which fixes 5 config.h macros, but breaks the Linux build), it fixes 5 macros and works for both FreeBSD 8 and Linux. --- configure.ac | 39 ++++++++++++++++++++++++++++++--------- 1 file changed, 30 insertions(+), 9 deletions(-) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index 6da71c22..816638e9 100755 --- a/configure.ac +++ b/configure.ac @@ -442,8 +442,35 @@ m4_define([QUAGGA_INCLUDES], #endif /* TIME_WITH_SYS_TIME */ ])dnl -AC_CHECK_HEADERS([sys/un.h net/if.h netinet/in_systm.h netinet/in_var.h \ - net/if_dl.h net/if_var.h net/netopt.h net/route.h \ +dnl HAVE_NET_IF_H must be discovered by the time the longer AC_CHECK_HEADERS +dnl round below execution begins, otherwise it doesn't properly detect +dnl HAVE_NETINET6_IN6_VAR_H, HAVE_NET_IF_VAR_H and HAVE_STRUCT_IN6_ALIASREQ +dnl on FreeBSD (BZ#408). + +AC_CHECK_HEADERS([net/if.h], [], [], QUAGGA_INCLUDES) + +m4_define([QUAGGA_INCLUDES], +QUAGGA_INCLUDES +[#if HAVE_NET_IF_H +# include +#endif +])dnl + +dnl Same applies for HAVE_NET_IF_VAR_H, which HAVE_NETINET6_ND6_H and +dnl HAVE_NETINET_IN_VAR_H depend upon.
