[Xorp-users] How to Launching Net-SNMP via the router manager?

[Bruce Simpson]

Hi,

I'm not fully up to date with how SNMP support in XORP may have changed 
since the 1.5 release.
I understand XORP has since cut over to using shared libraries in the 
build by default.

However I have a few questions:
* Which OS platform are you running XORP on?
I need to know this because the runtime dynamic linker behaviour differs 
across platforms.

* Are you running XORP after it has been installed using 'gmake 
install', or are you running XORP from a source tree checkout?
I need to know this because it looks as though you are attempting to use 
XORP's SNMP MIB support without installing XORP.

Based on the log output and configuration file in your post, it looks as 
though you are attempting to load the MIB module into the Net-SNMP 
daemon process without using 'gmake install' first to install XORP on 
your system.

I don't believe this is a use case we can support, because shared 
objects found in a .libs directory need to be re-linked by libtool 
before installation -- they should not be used directly. So it is highly 
likely that the MIB module you are attempting to load into Net-SNMP has 
missing runtime library dependencies.

To confirm this, you'd need to use the 'ldd' command on the 
/usr/local/xorp/mibs/.libs/bgp4_mib_1657.so file. However, not all 
platforms support listing shared library dependencies directly, which is 
why I need to know what platform you are running XORP on when reporting 
problems of this kind, it is essential information.

thanks,
