Comment 1 Guido Falsi 2022-06-18 11:13:41 UTC

Hi,
From your log the reported missing header file is 'net-snmp/library/snmpUDPIPv6Domain.h'

which is part of the net-mgmt/net-snmp port. ALso it is being included from another include that is part of net/net/snmp (/usr/local/include/net-snmp/session_api.h)

The missing include file is installed by the net-mgmt/net-snmp port only when the IPV6 option there is enabled, which is the default.

Could you check if you have the IPv6 option enabled there? If it is not enabling, does enabling it allow asterisk to build successfully?


There is not much the asterisk port can do to fix this and the ports system has no facility for a port to force required options in another port.

Is IPv6 a mandatory prerequisite for running asterisk? 

If it is not, Asterisk should build without failing if net-im/net-snmp is configured without IPv6. There are infrastructures where disabled IPv6 is mandatory in local LAN.

Could you please report this upstream if Asterisk18 is designed/allowed to run in IPv4-only infrastructures?

(In reply to p5B2EA84B3 from comment #2)

AFAIK no IPv6 is not required to build asterisk.

But the failure is not due to asterisk failing because net-snmp is compiled without IPv6 from what I can see.

It looks like net-snmp installs an include file, that requires another own include file which instead is installed only when IPv6 is preset, so this looks to me like an internal problem to net-snmp.


I will take a look to confirm this but you should also investigate yourself.


To summarize, my opinion at present, until I have time to investigate further, is that the issue is triggered by asterisk build but is really internal to net-snmp.

Hi zi,

I'm CCing you as the maintainer of net-snmp.

Looks like when net-snmp iss compiled with IPV6 disabled it still tries to include an include file only installed when building the port with IPv6 support.

this is the relevant part from the OP log:

#include <net-snmp/library/snmpUDPIPv6Domain.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Looks like even if IPv6 is disabled NETSNMP_TRANSPORT_UDPIPV6_DOMAIN is still defined in the installed includes, causing this error.

I could not find an toggle related to this in asterisk which is only including some higher level includes from net-snmp. This looks like an internal define.

Could you give me feedback?

Thanks in advance!



To OP:

could you also attach the latest build log for net-snmp with IPv6 disabled? Could be useful to better diagnosse the issue.

Comment 5 Ryan Steinmetz 2022-06-19 15:34:21 UTC

As a test, try editing net-mgmt/net-snmp/pkg-plist and removing the %%WITH_IPV6%% bit from the following lines:

%%WITH_IPV6%%include/net-snmp/library/snmpTCPIPv6Domain.h
%%WITH_IPV6%%include/net-snmp/library/snmpUDPIPv6Domain.h
%%WITH_IPV6%%include/net-snmp/library/snmpIPv6BaseDomain.h

Thanks for taking a look.

I reproduced the issue locally, and uncommenting the lines you indicate asterisk is able to build successfully.

I will try to run it, but I'm not using SNMP here, so I can't properly test it at runtime.

@zi: Thanks a lot!

p5B2EA84B3@t-online.de: could you verify asterisk now builds fine for you and in that case close this as resolved?

Thank you both, zi and Guido!

asterisk now builds fine.
