Re: [tipc-discussion] net/tipc/tipc_netlink.c:72: error: too few arguments to function 'genlmsg_unicast'

[Stephens, A. <all...@wi...>]

Hi Yordan:

As noted on the TIPC project website, TIPC 1.7.6 only supports Linux
kernels in the range 2.6.16-2.6.28.  A TIPC 1.7.7 release that also
supports later releases is being developed, but won't be available for a
while.

I suggest that you take a look at the TIPC 1.6 code that originally came
with Linux 2.6.32 to see what parameters genlmsg_unicast() is using
there.  Hopefully, it will be relatively easy to port this change to
your TIPC 1.7.6 code and get you up and running.

Regards,
Al
