Re: Help needed for compiling ns-2

[Shaogang Chen <shaogang@ecn.purdue.edu>]

Hi,
Thanks all folks for your valuable suggestions.  I can not find IP_MULTICAST_LOOP in my department by using all methods mentioned in the emails. Finally
what I do is adding 
#ifndef IP_MULTICAST_LOOP
#define IP_MULTICAST_LOOP  0x12 
#endif
to all files using  IP_MULTICAST_LOOP.

It works.

However, at almost the final compiling step, I run into a problem again.
The following is the error message:
c++ -o gen/ns_tcl.o -c -I/homes/chensg/ns-2.0b17/../Tcl  -I/usr/openwin/include  -I/homes/chensg/ns-2.0b17/../otcl-0.96 -I/homes/chensg/ns-2.0b17/../tk4.2/generic -I/homes/chensg/ns-2.0b17/../tcl7.6/generic   -I. -DNEED_SUNOS_PROTOS -DUSE_SHM -DHAVE_LIBOTCL0_96 -DHAVE_OTCL_H -DHAVE_LIBTK4_2 -DHAVE_TK_H -DHAVE_LIBTCL7_6 -DHAVE_TCL_H  -DNO_TK -Dabort=_ABORT -O2 gen/ns_tcl.cc
gcc: Internal compiler error: program cc1plus got fatal signal 4
*** Error code 1
make: Fatal error: Command failed for target `gen/ns_tcl.o'

In the console, there is error messges too:
sendsig: bad signal stack pid=3841, sig=4
sigsp = 0xf7ffd268, action = 0xf7732ba0, upc = 0xf778d424

I suspect my computer does not have enough memory to compile ns_tcl.cc.

Any suggestion  is welcome.
