Q: Problem compiling rtProtoLS with egcs-1.1.1

[Laxman Sahasrabuddhe <sahasrab@cs.ucdavis.edu>]

Hi,

For one of my research problems, I need to simulate a link-state routing
protocol in ns-2 (basically, I need an implementation of a simplified
version of OSPF).

So, I downloaded rtProtoLS (developed by Mingzhou Sun at RPI
http://networks.ecse.rpi.edu/~sunmin/rtProtoLS/) and tried compiling it
with egcs-1.1.1. This is what happened:

1. packet.cc and trace.cc compiled successfully.
2. While compiling rtProtoLS.cc, I got the following error(s):

----------------------------------------------------------------

Maybe the problem is in the compiler and I will be sending a bug report
to egcs-bugs@cygnus.com, but if you know a quick fix or you have some
suggestions, please let me know asap. Btw, I have sent a separate
request to Mingzhou Sun (the author of rtProtoLS).

Also, if you know of some other OSPF-like module (not rtProtoLS) that
works with ns-2, please let me know.

Thanks in advance,
Laxman.
