Motivation for this change

https://github.com/opencv/opencv/wiki/ChangeLog#version400

Things done

The following succeeds:

nix-build -E \
  'let pkgs = import ./. {}; \
   in pkgs.opencv4.override { \
       enableIpp = true; \
       enableUnfree = true; \
       enablePython = true; \
       enableGtk3 = true; \
       enableVtk = true; \
       enableFfmpeg = true; \
       enableGStreamer = true; \
       enableTesseract = true; \
       enableTbb = true; \
       enableGPhoto2 = true; \
       enableDC1394 = true; \
       enableDocs = true;\
     }'

If I enableOvis the build fails on https://github.com/opencv/opencv/issues/12851.

Thanks a lot for adding this! 👍

On a side note: do you know how to fix the broken Darwin build? I don't know enough about Nix on darwin, but in case we don't get this fixed, I'd temporarily disable darwin support in meta.platforms :)

+, enablePython    ? false, pythonPackages


Admittedly I'm not sure if that's a good idea. Python seems to be used often for such cases today and a full rebuild takes a certain amount of power and time and using Python is also one of the advertised ways of using opencv4 according the documentation.

Also, how is this supposed to be used? I'd love to see it possible to simply add opencv to a python environment to start hacking (but there's no build product in lib/pythonX.X).

@Ma27 thanks for reminding me to also have Python support. I forced-pushed a opencv4 attribute in python-packages.nix. Note that 4.0.0.nix is a copy of 3.0.0.nix so the way we handle Python is the same as with opencv3.

@Ma27 thanks for the review. I've made some attempts at fixing the darwin build but failed so far.

So it looks like a linker issue:

[ 62%] Linking CXX shared library ../../lib/libopencv_videoio.dylib

make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/build.make:193: lib/libopencv_videoio.4.0.0.dylib] Error 1

Apparently NSData is part of the Foundation framework. I don't see -framework foundation anywhere in the opencv sources so I tried adding it to the makefile of the failing videoio module here. I also added foundation to the dependencies of 4.0.0.nix. Unfortunately that didn't fix the problem.

Instead of disabling darwin support I could try just disabling the videoio module on darwin.

@basvandijk I just tested the Python support with the following expression (I checked out your branch locally):

with import ./. { };
{
  env-py3 = python3.withPackages (ps: [ ps.opencv4 ]);
  env-py2 = python.withPackages (ps: [ ps.opencv4 ]);
}

The output path has a python directory (with a setup.py and a cv2 directory with the python bindings), but they are not usable, as there's no built Python artifact that can be used automatically (they usually live in lib/pythonX.X/site-packages).

Unfortunately I don't know the package well enough to provide a reliable approach for fixing this.

Apart from that the expressions seems fine, if Borg is happy, this should be mergeable soon. Thanks a lot for the work! 👍

If I enableOvis the build fails on opencv/opencv#12851.

The issue has been fixed in opencv/opencv_contrib#1913, we should probably apply that as a patch.

Side note: @basvandijk no need to manually call the bot, since you are a trusted user for ofBorg a build job will start automatically every time you open a PR or push new commits to one of your PR.
It creates a duplicate build job if you call for the bot on top of it.

basvandijk · 2018-11-26T22:45:16Z

@c0bw3b thanks for the heads up. I didn't know ofborg would rerun on forced pushes. Good to know.

@kalbasit I applied the fix for ovis.

@Ma27 I will look into the Python issue next.

The following issue incl. potential work-around is relevant regarding the Python issue: opencv/opencv#13202

Ma27 · 2018-11-27T21:38:49Z

Thanks a lot for the link, I only looked at the documentation :)

Does this result in building issues as well? In case this applies for OpenCV 4 as well, we could either comment the relevant parts out and wait for an upstream fix or add a warning during evaluatin (e.g. with builtins.trace that the Python bindings are currently broken).

basvandijk · 2018-11-28T05:48:42Z

Does this result in building issues as well?

The library builds successfully but the python bindings are in the wrong place.

Before disabling or adding warnings I would like to try out the suggestion in the linked issue that brings back the old behaviour:

OPENCV_SKIP_PYTHON_LOADER=ON
OPENCV_PYTHON3_INSTALL_PATH=...site/dist-packages location...

I have some time to work on this tomorrow evening.

Ma27 · 2018-11-28T13:38:10Z

That's even better! I mainly wanted to provide options what to do in case we don't get to fix it :)
