#750 closed Bug / Defect (fixed)

--multihome on OpenSolaris needs -D_XPG4_2

Reported by: Gert Döring Owned by: Gert Döring
Priority: minor Milestone: release 2.4
Component: Generic / unclassified Version: OpenVPN git master branch (Community Ed)
Severity: Not set (select this one, unless your'e a OpenVPN developer) Keywords:

Description

the header definitions we need are protected

#if defined(_XPG4_2)
/*
 * The cmsg headers (and macros dealing with them) were made available as
 * part of UNIX95 and hence need to be protected with a _XPG4_2 define.
 */
...
/* Amount of space + padding needed for a message of length l */
#define CMSG_SPACE(l)                                                   \
        ((unsigned int)_CMSG_HDR_ALIGN(sizeof (struct cmsghdr) + (l)))

when adding that to CFLAGS, --multihome works nicely both for IPv4 and IPv6 (both "master as of today" and with the fix for trac #634).

So basically this is just a bit of "adding stuff to autoconf", "googling" and testing...
