[Xorp-users] compilation problmes with mips

Sat Mar 21 00:17:21 PDT 2009

Thanks a lot pavlin,

Your comments are indeed very help full for me.

I could able to resolve the compilation issues. Following are my changes .

1) --wiith-LD = mips-linux-ld

2) CFLAGS = "mxgots" 

3) CXXFLAGS = "mxgots"

4) Enableing the PIMSM V1, PIMSM V2 and IPIP kernal modules.

With above changes i could able to run the xorp on my target board.

Through testing i found that it doesnot support immedieate leave , am i right ?

To  supports  this do i need change any thing in config.boot ?

How many minimum number of multicast groups it can support ?

Do we have any control like on the specific interface we can allow only the specific multicast range addresses ? 

Please send your comments

regards
Kanth

Kanth,

Before I try to answer your questions I'd like to emphasize that if
you want to use XORP for multicast routing, you MUST use PIM-SM
(i.e., IGMP only is not enough).

The error you are seeing ("... is not a valid libtool object")
doesn't indicate an obvious issue. Here are few things that you can
try:
* Start with a clean source and build tree

* Don't use parallel make like "gmake -j4" in case you are. You
  could try "gmake -j1", but I think "-j1" is the default anyway.

* Double-check that your cross-compilation environment is setup
  properly (e.g., try to cross-compile other software that you know
  can be cross-compiled).

* Try using "--enable-static --disable-shared" argument to ./configure

* Try using older XORP release (e.g., XORP-1.5).

For multicast you need (at least) the following processes/modules:
fea/mfea, igmp, rib, fib2mrib, pim.

Depends on the setup, you might need some unicast routing protocols
as well (unless all unicast routes are static and installed outside
of XORP).

igmp itself depends only on fea/mfea, but as I mentioned before you
must run pim.

Pavlin
