Why doesn't mib2c like the MIB file I'm giving it?

This is most likely the same problem as the previous entry. mib2c takes the name of a MIB object, not the name of a file (or a MIB module). Try using the name of the MODULE-IDENTITY definition.

Another possibility is that the MIB may contain syntax errors. Try running it through 'snmptranslate' or a dedicated SMI validation tool (such as 'smilint' or the on-line interface at http://wwwsnmp.cs.utwente.nl/ietf/mibs/validate/)
