[oi-dev] net-snmp perl support

[Alexander Pyhalov]

Hello.
Can someone confirm that current 32-bit net-snmp in OpenIndiana /dev 
actually has embedded perl support?

As far as I see it's not true:
# /usr/sbin/i86/snmpd -f

/etc/net-snmp/snmp/snmpd.conf: line 124: Warning: Unknown token: 
disablePerl.
/etc/net-snmp/snmp/snmpd.conf: line 125: Warning: Unknown token: perl.

# elfdump /usr/lib/libnetsnmpagent.so |grep boot_DynaLoader # --shows 
nothing
#
I ask because I have difficulties with enabling embedded perl in 
net-snmp. In fact, not with net-snmp, but building illumos-gate with new 
net-snmp:

However, perl support seems to be "more alive":

embedded perl support failed to initalize
NET-SNMP version 5.4.1.2
Received TERM or STOP signal...  shutting down...

Can't open perl script "/etc/net-snmp/snmp/snmp_perl.pl": No such file 
or directory

Also I see that in OmniOS embedded perl support for net-snmp is 
explicitly disabled...
