Hi!

Rajbal> When checking a set MIB modules using smilint, I get the Rajbal> following errors-

Rajbal> How do I define/setup a base module (since that seems to be Rajbal> core of the problem)? Is there anything else I am missing?

Frank> The error message may be misleading. It means that these descriptors Frank> (Gauge32, etc.) are well defined by the SMI language specification (in Frank> modules that are part of the language specification). So, when libsmi Frank> finds a definition for these types, it is only valid if the current Frank> module is such a base module (SNMPv2-SMI in case of SMIv2). You are Frank> not allowed to have a definition of these types in your own modules.

David Perkins gave me a hint, that this is not true if your module is an SMIv1 module. Thanks, Dave! In this case it seems that your module is in fact SMIv1, so the level 1 error message should be turned into a warning in tis case.

I would recommend however, that you don't define types that are originally defined in SNMPv2-SMI in a module not named SNMPv2-SMI, so that you don't have to change every IMPORT clause in other modules that make use of these types. If you have to use the historic SMIv1 language for any reasons, you could use the output of "smidump -f smiv1 SNMPv2-SMI" and stick with the module name SNMPv2-SMI from which you import the mentioned types.
