now you need a linux machine to walk away......

install net-snmp .... and put your mib at mibs directory /opt/net-snmp/mibs

and run mib2c

$mib2c LINEAR-MIB.txt:linearProject

this generate two files : linearProject.h and linearProject.c ......

you need modify the .c file to do what you need.......

and put this file at nios2-linux/uClinux-dist/user/net-snmp/net-snmp-5.2.1/agent/mibgroup

add your mib at menuconfig and voila.....

good luck
