Migration to Qt5

Qt4 will be removed from Debian in the next stable release so OTB should switch to Qt5.

mentioned in merge request !3 (merged)

changed milestone to %6.6.0

The branch is now compiling. There are some lines that I commented because the function are no longer available in qt5 (http://doc.qt.io/qt-5/qtextcodec.html / http://doc.qt.io/archives/qt-4.8/qtextcodec.html setCodecForCstring(), setCodecForTr(), codecForCString() and codecForTr() ).

We also need to change the use of qt4 in the documentation and in the superbuild/packaging.

Cool!

Does Megatron, hulk and leod have Qt5 already installed ? If yes we can probably register the feature branch in the list of tested branches.

How can we link this issue with the feature branch qt4to5? (https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb/tree/qt4to5).

There is something strange on my side in the gitlab GUI for this issue as I can't create a merge request or branch from the issue description. It is only written "Checking branch availability" with a progress circle which turn indefinitely at the top right of the issue description.

@aregimbeau do you see the same thing?

No I do not have the "Checking branch availability". But a merge request is already linked to the issue!

About linking the issue and an existed branch that is unfortunately impossible for now in gitlab... But I think that this is a feature request.

Simple question : should we keep backward compatibility with Qt4 or not?

Simple answer: No

same answer, Qt4 support is ending soon

After building and using Monteverdi with qt5 and package qwt-qt5 we have an encoding problem, warning and debug messages are unreadable :
