Description Anindya Mukherjee 2019-09-11 04:44:58 UTC
graphics/darktable: release 2.6.2_3 fails to build under ports-mgmt/synth due to OpenMP dependency causing synth's dependency check to fail. I have described the issue in detail on this thread: https://forums.freebsd.org/threads/synth-cannot-install-or-upgrade-darktable.72250/
Comment 1 Baptiste Daroussin freebsd_committer 2019-09-11 07:12:38 UTC
which version of freebsd are you using?

I suspect a bug in synth, can you provide the full build log from synth?
Comment 2 Alexandre C. Guimarães freebsd_committer 2019-09-11 14:10:48 UTC
Same problem with poudriere. I am on 12.0.
Comment 3 Alexandre C. Guimarães freebsd_committer 2019-09-11 14:15:18 UTC
(In reply to Alexandre C. Guimarães from comment #2)

Sorry, that was an 11.2 jail.
Comment 4 Alexandre C. Guimarães freebsd_committer 2019-09-11 14:23:16 UTC
Ignore my previous two comments. I was tring to install from the 12.0 jail. :-(

synth build log for darktable

Please note the lines with "actual-package-depends: dependency on /usr/lib/libomp.so not registered (normal if it belongs to base)"
Comment 6 Anindya Mukherjee 2019-09-11 15:37:31 UTC
I'm on 11.3-RELEASE-p3
Comment 7 Jean-Sébastien Pédron freebsd_committer 2019-09-13 18:55:59 UTC
Hi!

I couldn't reproduce a check or build failure locally. However, if I inspect the produced package, it doesn't require/depend on libomp.so. So there must be something wrong with that Makefile.

I will keep you posted with my findings!
Comment 8 Anindya Mukherjee 2019-09-15 08:20:13 UTC
Thanks for the update! Here is my take on it:

Did you use synth? I don't think the build fails. On my machine the package built successfully (under synth) and the .tgz file was generated. However, then synth checks for dependencies and fails on the dependency on libomp.so.

The dependency check uses /usr/ports/Mk/Scripts/actual-package-depends.sh (with argument /usr/lib/libomp.so). In particular, the command

pkg which -q /usr/lib/libomp.so

is used to find a package providing libomp.so (sorry if I'm being pedantic). Since the lib is part of base no such package is found. The next command run is

pkg query "\"%n\": {origin: \"%o\", version: \"%v\"}" ""

with an empty string because no package is found, resulting in non-zero exit status. That's why synth fails the dependency check.

Btw how did check for dependencies? I'm guessing pkg info -d? It won't show the dependency on libomp.so since it is provided by base and not ports. The built darktable binary does have a runtime dependency on openmp as seen by running

ldd /usr/local/bin/darktable|grep -i libomp

So, I think the Makefile is probably okay. It looks like a synth bug now IMHO.
Comment 9 Anindya Mukherjee 2019-09-15 08:23:22 UTC
To precise, the problem arises when you ask synth to install the package it just built. Because of the dependency check failure the new package file is deleted during the repository rebuild step and install fails.

synth test graphics/darktable

runs just fine.

Patch to simplify the dependency to libomp.so

Hi!

I couldn't reproduce the issue with FreeBSD 11.2, 11.3 or HEAD in Poudriere.

However, I looked at other ports using OpenMP. Based on that, here is a patch which simplifies the dependency to libomp.so. Hopefully it will help you.

Could you please test it?
Comment 11 Jean-Sébastien Pédron freebsd_committer 2019-09-16 15:49:28 UTC
FTR I tested with `poudriere testport` which also installs the package it built. I believe that's the equivalent to `synth test`.
Comment 12 Anindya Mukherjee 2019-09-16 18:19:11 UTC
Thanks again for the effort! I'll retest with this patch and report back. I think I need to report this to marino because I now believe the problem is with synth.

Basically if there is any dependency on a library outside of ports in the same way as there is for limomp.so synth will fail.
