Subject: [libvirt] OSX 10.6 build failures
Hi us,
Going through the process of getting libvirt to compile on OSX,
making
notes of the failures on the way through (from a clean system) to
be
fixed.
a) libtool -> glibtool
    libtoolize -> glibtoolize
It turns out that autogen.sh is hard coded to use "libtool",
and
    wants the GNU version.
OSX supplies has it's own version, without a --version option,
so
    autogen.sh fails.
Installing GNU libtool through MacPorts, makes it available as
    glibtool, with libtoolize being glibtoolize.
Adjusting autogen.sh to detect that, then set LIBTOOL and
LIBTOOLIZE
    appropriately was fairly trivial.
Will submit a patch to fix that in a bit.
b) pkg-config
The next thing to barf was autoconf, complaining about
AC_MSG_ERROR
    not being a defined macro.
Googling with some persistence showed this is caused by
pkg-config
    not being installed.  Fixed that.
Will submit a patch for that too.  Probably "pkg-config
--version"
    based, copying the approach used for the other autogen.sh
checks.
c) This is a compilation failure, one I don't readily know how to
fix:
...
    Making all in src
    make  all-am
      CC     libvirt_util_la-network.lo
    util/network.c: In function 'getIPv6Addr':
    util/network.c:50: error: 'struct in6_addr' has no member named
...
's6_addr16'
    util/network.c:50: error: 'struct in6_addr' has no member named
...
's6_addr16'
    util/network.c:50: error: 'struct in6_addr' has no member named
...
's6_addr16'
    util/network.c:50: error: 'struct in6_addr' has no member named
...
's6_addr16'
    make[3]: *** [libvirt_util_la-network.lo] Error 1
    make[2]: *** [all] Error 2
    make[1]: *** [all-recursive] Error 1
    make: *** [all] Error 2
    $
They're the only problems so far, though most things have been
disabled 
on the ./configure line so it's only the client libraries being
built.
Anyone know how to address that third one?
% man ipv6
Address Format
           struct sockaddr_in6 {
               sa_family_t     sin6_family;   /* AF_INET6 */
               in_port_t       sin6_port;     /* port number */
               uint32_t        sin6_flowinfo; /* IPv6 flow information
*/
               struct in6_addr sin6_addr;     /* IPv6 address */
               uint32_t        sin6_scope_id; /* Scope ID (new in 2.4)
*/
           };
struct in6_addr {
               unsigned char   s6_addr[16];   /* IPv6 address */
           };
% vim libvirt/src/util/network.c
43 static int getIPv6Addr(virSocketAddrPtr addr, virIPv6AddrPtr tab)
{
 44     int i;
 45 
 46     if ((addr == NULL) || (tab == NULL) || (addr->stor.ss_family
!= AF_INET6    ))  
 47         return(-1);
 48 
 49     for (i = 0;i < 8;i++) {
 50         (*tab)[i] = ntohs(addr->inet6.sin6_addr.s6_addr16[i]);
 51     }
 52 
 53     return(0);
 54 }
I guess it's a typo, should be "addr->inet6.sin6_addr.s6_addr[i]", but
not 
"addr->inet6.sin6_addr.s6_addr16[i]".. :-)
BTW: Got it under Linux, not sure if the ipv6 implementation is same on OSX. :-)
