I ran into few problems when compiling my mib using
mib2c.iterate.conf. Mentioned below is the sample of the table.
1. The data structure that got generated "sensorTable_entry" had
problem. The sensorIndex was repeted twice.
struct sensorTable_entry {
/* Index values */
long sensorIndex;
/* Column values */
long sensorIndex;
long sensorSdrVersion;
.....
....
}
2. bad function definition sensorTable_createEntry(long sensorIndex,)
as you can see the function prototype has a problem.
3. after fixing the above two and populating the table using a dummy
function inviked in initialize_table_sensorTable, I had a crash when i
performed snmpwalk. Attached is the backtrace from the crash.
Hope someone can take a look and give me pointer to fix this, the
crash problem but the problem with mib2c.iterate.conf, a perl expert
need to take a look.
Thanks,
Sridhar
