Re: SNMP::MainLoop

Hi Rob...

Thanks for the reply. One more questions:

I want to add net snmp in perl module using Cygwin. I have copied the net
snmp source in home and have following configuartion set.


./configure \
	--with-mib-modules="host agentx disman/event-mib examples/example" \
	--with-out-mib-modules=host/hr_network --with-libs="-lws2_32" \
        --disable-embedded-perl --with-perl-modules \

Then i run "perl Makefile.PL -NET-SNMP-IN-SOURCE=true" in /netsnmp/perl.
There are no errors generated when I run this command but when I
"make" command it gives error.

-----------------------------------------
Error is :

---------------------------------------------

In the link "http://net-snmp.sourceforge.net/docs/perl-SNMP-README.html",
it said that we need to install regex. I coudnt get the regex
from the link provided. Is the error because of regex?

Thanks in advance.
