[Xorp-users] Problems verifying compalation

[Christopher David Chapman]

First my deep thanks to Pavlin for all his support.

Pavlin has been working with me to resolve this off-list and I thought I should sum up how we sorted it.

It turns out that the problem was caused by the SSP protection of the Gentoo hardened toolchain causing run-time problems. To resolve the issue I used gcc-config to switch the gcc profile to "hardenednossp" and recompiled xorp.

I then got some errors while running xorp_rtrmgr:

[ 2007/08/15 17:35:56  INFO xorp_rtrmgr:6773 RTRMGR +239 master_conf_tree.cc execute ] Changed modules: interfaces, fea, mfea4, rib, fib2mrib, igmp, pimsm4 
[ 2007/08/15 17:35:56  INFO xorp_rtrmgr:6773 RTRMGR +96 module_manager.cc execute ] Executing module: interfaces (fea/xorp_fea) 
[ 2007/08/15 17:35:56  ERROR xorp_fea:6774 LIBCOMM +114 comm_sock.c comm_sock_open ] Error opening socket (domain = 10, type = 2, protocol = 0): Address family not supported by protocol 
[ 2007/08/15 17:35:56  ERROR xorp_fea:6774 LIBCOMM +114 comm_sock.c comm_sock_open ] Error opening socket (domain = 10, type = 2, protocol = 0): Address family not supported by protocol

This was because I have disabled IPV6 in the kernel and was fixed by recompiling xorp after re-running the configuration with the "--disable-ipv6" switch.

Cheers
	Chris

What Gentoo version and what compiler are you using?
We have Gentoo 2006.1 with gcc-4.1.1 and we don't see that problem.
Can you run gdb on the coredump file and trace where it failed:

gdb test_vif -c <corefile>
bt

Thanks,
Pavlin
