[Linphone-users] about getaddrinfo in IPv4

[Juei-Cheng Lo]

Dear list,
    I am using linphone 0.12.2 on my red-hat 9.  Whenever I setup registrar 
using host name instead of numeric representation, linphone crashed.  After 
tracing the code I found the problem is at guess_local_address of 
osipua/src/utils.c:

        hints.ai_family=PF_UNSPEC;
        hints.ai_socktype=SOCK_DGRAM;
        err=getaddrinfo(address_to_reach,"5060",&hints,&res);
               // ignored in between
        sock=socket(res->ai_family,SOCK_DGRAM,0);
        tmp=1;
        err=setsockopt(sock,SOL_SOCKET,SO_REUSEADDR,&tmp,sizeof(tmp));

     In my system the socket call returns -1 because of unsupported 
ai_family.  I suspect the res->ai_family returned from getaddrinfo was IPv6 
which fails the socket call.  Did any of you ever have this problem?  Thank 
you.

Richard
