Tiger does not have 'IPV6_TCLASS' defined in /usr/include/netinet6/in6.h. The IPV6_* definitions vary on Tiger from recent macOS. It also seems to be missing on Leopard, Mac OS X 10.5.x – a PowerPC only issue?

The same failure happens on PPC Leopard, Mac OS X 10.5.8. Its /usr/include/netinet6/in6.h similar to Tiger's version.

I tried building using the same compilers and they built, so I guess it's not that.

I don't know if this is related, but this differed from my log:

:info:configure no

On my system: IPV6_TCLASS is in <netinet6/in6.h> if that helps.

It's not in ​netinet6/in6.h.auto.html (via ​10.5.8)

Perhaps it renamed, moved or somewhere else?

You mean on ports.macports.org? When I checked earlier, just after we removed the legacysupport, it was in red (10.5/6) - and then turned green a bit later. I thought it reflected the current status.

If it's missing, maybe it's something that could/should be added to the legacy-support?

That's not a problem:

checking for -force_load linker flag... ld: unknown option: -force_load
no

it checks for the flag, doesn't find it supported, moves on, doesn't use it. That is how it is supposed to work.

Does anyone need unbound on Leopard and Tiger? If so, I can take a look at seeing if it is fixable...

GnuTLS needs it, while in turn wget und GnuPG2 need GnuTLS.

[kencu (Ken)]

working on it.

BTW, looks like only the +dane variant of gnutls needs unbound, which I don't use, and I guess this is why I never have seen this.

What does the dane variant give you? Perhaps you don't need it?

Anyway, fix coming shortly.

DANE is an extension for HTTPS to handle self-signed certificates of a web server with the help of Certificate Authorities (CA). The web server can tell which CAs to trust. I am not sure whether it is still useful today… (or more needed than ever)

Great to hear. Did it work on 10.4 as well?

still have my old G4 I maybe could use it on

[kencu (Ken)]

for me it did equally well on the test suite on 10.4 PPC.

I'm not sure if the specific thing that was fixed by the patch was tested, however. It's an IPV6 thing, and so -- seemingly -- optional I guess. Glad that works for you.

To find the missing define, I don't do anything too fancy -- just look in a newer SDK with "the silver searcher" and see what it is supposed to be.

This fix could be added to the proper header in legacysupport, indeed, if there is more than just this one use of it in the ports tree. (and once we fix legacysupport 1.1 to work properly, which it presently does not, it appears).

[ballapete (Peter "Pete" Dyballa)]

test OK here on PCC Tiger too.

[ballapete (Peter "Pete" Dyballa)]

With unbound @1.17.0_0 the file services/listen_dnsport.c is being patched so that it compiles. In the end the port builds and so this ticket can be closed.
