Seems to be an an issue with removal of QTKit in XCode 8? ​https://github.com/opencv/opencv/pull/7159

The fix was merged to opencv trunk, but they aren't going to release v3.1.x. v3.2 planned for 2016 Q4. Is there any chance to update the port with trunk sources?

Relevant links:

• Link to opencv bug and fix: ​https://github.com/opencv/opencv/issues/6913 (also offers side-effect-laden workaround of: cmake -DBUILD_opencv_videoio=OFF . for current released source)
• Link to homebrew workaround (building off of head): ​https://github.com/Homebrew/homebrew-science/issues/4104

I don't know how to take advantage of the above because I don't know how to force the port to have build options outside of what is defined in the variants (which videoio isn't) and/or force it to build off of the repo HEAD (as the homebrew people can)

Please note, that above patch relies on cmake portgroup's version 1.1, which isn't yet released. (@RJVB, I've added ticket #52699 where you might want to add some comments as description.)

I'll append the missing patch files in a second step now...

[mkae (Marko Käning)]

The new cmake port group version 1.1 (which deserves a separate ticket for discussion, I suppose)

[mkae (Marko Käning)]

For a final release within MacPorts it might be questionable to use the linux platform-specific bits in opencv_Portfile.diff...

[tmenguy]

Thanks a lot @mkae ... but excuse my freshness ... but how do I apply your patches and this cmake group 1.1? Thanks for your work, and your help!

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #52747.

Sorry for my late response, but I was waiting for the owner to test the patches... You could apply them yourselves to a local ports tree until the ticket owner commits this.

[tmenguy]

No pb @mkae, that would be awesome if you could do something ... in all case enjoy your week end

Is there any chance to get opencv with MacOS Sierra functional in near future ?

[tmenguy]

@karo11 the provided patches are working well for me ... (except the portfile one, you need to adapt i a bit, but very easy) ...

[karo11]

Hmm, encouraging! Still macports has in meantime a version change. I don't know if I should try to mingle into?

[stromnov (Andrey Stromnov)]

Hi! Feel free to provide pull request for OpenCV 3.1.0 which will not break compatibility with older macOS releases (at least 10.9, 10.10 and 10.11 with new XCode).

[tmenguy]

@karo11 : was like you, but needed to make it work ... for my work, very quick to do

[mkae (Marko Käning)]

@tmenguy, what exactly did you do? Did you use the set of patches I've uploaded 3 weeks ago?

If this is it, I can, of course, create a PR, as @stromnov is not going to do so.

But before I do that I'd like to learn what you did, @tmenguy. :)

Which OSX/macOS versions did you test your modified opencv port on?

[nortcele]

I tested the proposed modifications on macOS 10.12.1, the build and installation worked for me. I have not tested all opencv functions but I installed a software that depends on opencv and the sofware worked as expected.

To build opencv, I first cleaned and uninstalled all installed ports.

Then I updated Macports.

Then I duplicated Macports opencv folder to my local repository with Macport set to use my local repository. Then I added the three proposed patches in the "files" subfolder. I modified the Portfile file with your proposed modifications (I'll add a new version of the patch as this file has changed since yours).

And then "sudo install opencv".

I am reproducing the same steps on another machine with 10.12.1 too but as it is a really slower machine and as I have a customised GCC5 dependance, it is still building.

In some days I'll try the same steps with macOS 10.10 and 10.9…

I tested the same operations on 10.9.5 and 10.10.5 and it worked too.

@rjvb, should this

-DENABLE_SSSE3=ON

perhaps rather be

-DENABLE_SSE3=ON

???
