NTP fails to compile on El Capitan

[jos@…]

Also a nice opportunity to go to version 4.2.8p3

What's up with "MacOSX10.11.Internal.sdk"? Why "Internal"?

[jos@…]

I have removed "Internal" in the makefile, that error goes away, but then I still get "ld: symbol(s) not found for architecture x86_64" I don't know where "Internal" came from.

[mdeaudelin (Mathieu Deaudelin-Lemay)]

The warning message about "MacOSX10.11.Internal.sdk" sounds like it is caused by a hardcoded value, but has no side-effect. I can build ntp successfully on OS X 10.11 even with this warning message.

However, if I disable all my installed ports, I can reproduce the linker error reported here. To me, this sounds like ntp has a missing dependency on something else.

[danielluke (Daniel J. Luke)]

I just installed El Capitan today, so I'll be taking a look at this shortly.

[danielluke (Daniel J. Luke)]

According to the -dev mailing list, trace mode is currently broken on El Capitan. Are you only experiencing build failure(s) when running with trace mode?

[danielluke (Daniel J. Luke)]

port updated to 4.2.8p3 in r140933. I'm going to mark this closed for now, please re-open if you can reproduce the problems without trace mode (or after trace mode is working on El Capitan).

[jos@…]

I have reinstalled Xcode, reinstalled Macports and I still can reproduce this error. Only "Internal" has gone.

Reported same error to the Pool NTP list in December 2014: ​http://lists.ntp.org/pipermail/pool/2014-December/007292.html and got some answers in March 2015: ​http://lists.ntp.org/pipermail/pool/2015-March/007322.html. This was Yosemite. At that time (December 2014) I installed Macports and could build NTP 4.2.8p0, 4.2.8p1 and 4.2.8p2 untill I upgraded to El Capitan. Then I reported here. That is my story! :(

macports@… reported the same error with disabled installed ports. Did you try that?

... so it's not a problem specific to El Capitan for you? That points to something unusual in your setup.

Please upload a failing build log without trace mode if you can reproduce the issue.

That is possible, but once again:

• Reproducible by others
• Why not possible to build under Yosemite, but did with Macports installed under Yosemite
• Did you try with other ports disabled?
• I already attached a main.log and that gives the same error, but I will attach again

[jos@…]

I did a fresh install of Xcode/Macports on another (El Capitan) computer and I get the same error. I don't think it is something specific to my systems.

[danielluke (Daniel J. Luke)]

Replying to jos@…:

That is possible, but once again:

Since you're asking for free help from a volunteer, I suggest you adopt a more cooperative tone (if I could reproduce the issue, I would work to fix it, if you can reproduce the issue and you can generate a patch, I will apply it).

• Reproducible by others

only one other report, no build logs.

buildbots built it fine (unfortunately there's no El Capitan build bot working yet).

• Why not possible to build under Yosemite, but did with Macports installed under Yosemite

I don't have any way of knowing why your system worked that way.

• Did you try with other ports disabled?

the buildbots did

• I already attached a main.log and that gives the same error, but I will attach again

The main.log you originally attached was the result from building while using trace mode, which does not work under El Capitan.

It's very likely that you have something installed that is preventing the build (that the ntp autoconf is picking up). This caused build failures previously which you solved by building with trace mode under Yosemite (which hid them). Since trace mode doesn't work in El Capitan, you're seeing the old problem again.

I'll take a look at the new build log you uploaded and see if there's anything I can see going wrong there.

[danielluke (Daniel J. Luke)]

Replying to dluke@…:

I'll take a look at the new build log you uploaded and see if there's anything I can see going wrong there.

I see two differences that are interesting:

1 - can you install macports openssl and attempt your build again and see if it succeeds? (my local build is opportunistically linking with openssl, the buildbots wouldn't have done so). I don't think this will fix it for you, but it's worth a shot. 2 - the configure script is finding -lelf for nlist on your system (:info:configure checking for library containing nlist... -lelf) - can you determine what libelf.dylib file is present, where it is, and what it's there for?

[danielluke (Daniel J. Luke)]

I just committed a revision (r141000) that should fix this for you (force the configure script to not look for libelf). It also adds some dependencies that would otherwise be opportunistically linked in.

[jos@…]

Amazing job! At last I can build ntp. I still don't understand why, but that is my problem.
I first tried to build with openssl but that wasn't enough, the other dependencies were indeed required. Libelf was a leftover from another install.

Now there are started two processes ntpd and after a few minutes one stops:

computer:~ jos$ ps auxwwww | grep ntpd
jvdven          23143   0,0  0,0  2445076    796 s000  S+   10:21pm   0:00.00 grep ntpd

And console says:

07-10-15 22:21:44,865 ntpd[23140]: ntpd 4.2.8p3@1.3265-o Wed Oct  7 19:32:18 UTC 2015 (1): Starting

07-10-15 22:24:44,862 ntpd[23140]: error waiting on child 23141: No child processes

That is new for me and could this be a build error? I start ntp with "sudo port load ntp" and I have unloaded OSX version. Shall I open a new ticket for this one?

[jos@…]

Follow up:
after a lot of testing I found out why I had two ntpd processes. I had defined a server name instead of IP address. Ntpd spawns a child process for DNS resolution.

Furthermore it is not necessary to have "ac_cv_search_nlist=no" and also libevent and libedit are not necessary.

Thanks for your help!
