Nope.
That tutorial is describing the older v4 (or UCD) MIB module API.
Most of the examples under 'mibgroup/examples' use the newer v5 API.
That works in a different way, and doesn't use REGISTER_MIB etc.
See
http://www.net-snmp.org/tutorial-5/
instead.

Because this example is showing the use of an "internal helper"
that does *all* of the work for you.
See
http://www.net-snmp.org/tutorial-5/agent/scalar__int_8c-example.html

Because the agent effectively hardcodes the contents of the MIB definitions.
into the code that implements that MIB.
The MIB file is essentially a design document - it's not needed to
provide the relevant values.
It *is* needed to translate the numeric OIDs etc that SNMP uses
back into "meaningful" textual forms. But if you're happy to work
with numeric OIDs, and bare values (ignoring display hints, enumerated
values, etc), then you don't need any MIB files at all.

Wrong.
You only need to run "make install" in the 'agent' directory.
And it shouldn't actually recompile most of the files anyway.
As long as nothing else has changed, then it should *only* recompile
'scalar_int.c', recreate the MIB module library, and relink the agent.
It would only recompile everything if you've changed some of the
main header files (or re-run configure).
