Hi, I had installed net-snmp-5.5 on Windows and am using Cygwin to add a new MIB module and compile it. I had added the new MIB file MY-MIB.txt to /usr/share/snmp/mibs and then loaded the MIB by running $ MIBS=MY-MIB;export MIBS Then using mib2c tool , I had generated both .C and .h file Then I placed both the .h and .c files under agent/mibgroup/ directory Next, to configure the package to find them and compile them into the agent, I tried running $ ./configure--with-mib-modules="myMib" Location to write persistent information (/var/net-snmp): setting Location to write persistent information to... /var/net-snmp checking if I need to feed myself to ksh... no checking for grep that handles long lines and -e... /usr/bin/grep checking for egrep... /usr/bin/grep -E checking for grep that handles long lines and -e...

But its throwing an error as above, before throwing this error it asks for a set of options, for which I just pressed enter. Please help me compile this MIB. Thanks in advance.
