You need to tell mib2c to load the MIB files that define the
MIB subtree you want to implement.
If you've got a file MY-MIB, that defines a subtree rooted at
.1.3.6.1.4.1.123456789 and named "myRoot", then try
mib2c MY-MIB::myRoot
If the MIB files aren't being loaded, then mib2c can't know what
object to generate code for.

You can always use the Net-SNMP experimental area.
Try defining a MIB that sits underneath
NET-SNMP-MIB::netSnmpPlaypen
That's *exactly* what this subtree is provided for!
(Just please make sure that you don't release any code
that uses this subtree.)

To start with, I'd advise compiling your new MIB directly into
the agent. That's one less complication to deal with when
debugging. Once you're confident that the module code is
working properly, *then* look at loading this dynamically,
or running as a subagent.
But to start with, keep things as simple as possible.

Work with a source tarball, and run
configure --with-mib-modules=myRoot ; make
You don't actually have to install things while you're
developing the new module - it's perfectly possible to
run the agent from the source tree.
