Re: [qpimd-users] qpimd in FreeBSD?

[bored to death]

hi,

sorry for delay to reply, i was kinda stucked at some other works.

i tried solving errors i mentioned in last post with the help of the hint Everton gave me.
so, i added
#include <sys/types.h>
#include <sys/socket.h>
this solved "'AF_INET undeclared" problem.

then, i read FreeBSD uses IPPROTO_IP instead of SO_IP, and i was hoping two structures were the same. so i added:
#define SOL_IP IPPROTO_IP
at the top of pim_igmp_join.c.
this solved "'SOL_IP undeclared" problem. but now , new errors appeared. this is what happened:

In file included from test_igmpv3_join.c:28:
/usr/include/net/if.h:294: error: field 'ifru_addr' has incomplete type
/usr/include/net/if.h:295: error: field 'ifru_dstaddr' has incomplete type
/usr/include/net/if.h:296: error: field 'ifru_broadaddr' has incomplete type
/usr/include/net/if.h:330: error: field 'ifra_addr' has incomplete type
/usr/include/net/if.h:331: error: field 'ifra_broadaddr' has incomplete type
/usr/include/net/if.h:332: error: field 'ifra_mask' has incomplete type
/usr/include/net/if.h:430: error: field 'addr' has incomplete type
/usr/include/net/if.h:431: error: field 'dstaddr' has incomplete type
*** Error code 1
i worked a while on it but i couldn't find a way to fix this error.

i will continue working on it, and i will be glad if anyone helps me.

thank you.

Yes, I think you should include the right includes for FreeBSD.
Check what "man setsockopt" recommends under FreeBSD.
In Linux, "man setsockopt" points out these headers:

#include <sys/types.h>
#include <sys/socket.h>

Then add those headers to the top of the file "pim_igmp_join.c".

I think you should also check what is the correct FreeBSD api for joining
source-specific multicast grupos. Under Linux, it goes like this:

/* This type should be defined somewhere in the system headers. */
struct group_source_req
{
  uint32_t gsr_interface;
  struct sockaddr_storage gsr_group;
  struct sockaddr_storage gsr_source;
};

struct group_source_req req;

setsockopt(fd, SOL_IP, MCAST_JOIN_SOURCE_GROUP, &req, sizeof(req));

Cheers,
