oqapy: dependancy to fixed version of libopencv-highgui2.4v5

[Nikolai Försterling]

on my kubuntu 16.10 when using your repo for oqapy, there's an unresolvable dependancy in liboqapy-iproc0 (via python-oqapy-iproc) that refers to libopencv-highgui2.4v5, which is not present here, but libopencv-highgui2.4-deb0 (2.4.9.1+dfsg-2.1) is.
I'd like to suggest to make the dependancy more "soft" like ">=libopencv-highgui2.4".

There's no ref to libopencv-highgui2.4v5

Anyway, I've made a new .deb with libcv2.4 (>= 2.4) you can try to install it.
If an error occur, please paste the traceback here.

Use:

$ wget http://www.oqapy.eu/releases/liboqapy-iproc0_0.1.2_amd64.deb
$ sudo dpkg -i liboqapy-iproc0_0.1.2_amd64.deb

[Nikolai Försterling (thefoster)]

Thanks for your very fast response.
Meanwhile i do thing this happens because of inconsistencies in opencv from ubuntu or opencv repo, as mist of the libs are named like libopencv-imgproc2.4v5 rather than libopencv-imgproc2.4 and libopencv-highgui2.4-deb0 is the only exception (without "*v5").
Maybe both of these facts prevent oqapy and its dependencies from installing, so this seems screwed in (K)Ubuntu 16.10.

[VinsS (vincent-vandevyvre)]

Ah yes, with dpkg it's not the same as apt, you have to install the libopencv yourself before.

Something like:
sudo apt-get install libopencv-core2.4 libopencv-highgui2.4 libopencv-imgproc2.4

Or by synaptic.

Forget my last post, I've installed Yakkety on a machine and that's not works.

I've filled a bug for that.

Hello Vincent,

thanks for that.
Sorry that i first thought it is your packages' dependancy and saw too late
that it is within ubuntu itself, so i'd opened that bug report myself.

I've fixed the depends issue but that's not usefull.

Oqapy has an other problem, PyQt4.QtWebkit is no longer packaged since Ubuntu-16.10 (yakkety) and there's no workaround possible.

So, don't install Oqapy on yakkety, zesty, ... it crash at startup.

I'm working on the Python3-PyQt5 version since several months but i'm not able to fix a date of release.

[Nikolai Försterling (thefoster)]

thanks for your effort, i'm afraid this means that oqapy won't be available to Ubuntu users before the successor of zesty?

[Nikolai Försterling (thefoster)]

Hi Vincent,

as package dependencies were messed up in yakkety, i upgraded to ubuntu
bionic(18.04) with additionall package sources from xenial(16.04) configured.

One issue that prevents installation of oqapy (when using xenial source) is
that python 3.6+ is newer than expected/"required" <3.6.

Using bionic source i can't find oqapy at all, although the path* exists.

Is this issue already known to you?

Best regards
Nikolai Försterling

The ppa bionic is now up to date.

Cheers,

[Nikolai Försterling (thefoster)]

Hello Vincent,

where do i get the dependancy "python3-exiv2" from?
It is neither in your ppa*, nor in xenial, and not (yet?) in bionic.

Have a nice start of the week

python3-exiv2 is now in bionic. Just copied from artful.

But it's in xenial since 16 Aug. 2016

[Nikolai Försterling (thefoster)]

Good morning Vincent,

Works now, thank you.

Best regards
