Re: Help needed for compiling ns-2

["Christoph Haenle" <christoph@starburstcom.com>]

Hi,

see if you can find IP_MULTICAST_LOOP in

/usr/include/netinet/in.h:#define  IP_MULTICAST_LOOP       0x12    /*
set/get IP multicast loopback   */  

If nothing else helps, you might want to try the biggest hack ever and
replace the constant in net-ip.cc with 0x12 (ughh!)

    -Chris.
