For your everyday image visualization I would recommend to just download the 
2014.10 installer, which gives you a ready-to-go Workbench with the most 
commonly used plugins activated. You don't have to compile anything in that 
case.

Yes, for your development you should use the ProjectTemplate. 2014.10 didn't 
have Qt 5 support (to be more correct there were a few *experimental* things), 
hence: 2014.10 ProjectTemplate -> use Qt 4 (> 4.7.x). Latest unstable 
ProjectTemplate -> use Qt 5 (Qt 4 if developing on Mac OS).

Regarding the error you have with USE_Blueberry: We need more information on 
your system, versions, and a pasted CMake output of the error to help you, as 
it is generally working since some month now for many many people. :) So I 
guess it is caused by some misconfiguration.

Note that we will have a new release next week which is why I our current 
master should be somewhat stable most of the time. Therfore I would recommend 
you to give the latest ProjectTemplate a try. Use Qt 5 in that case and use the 
official Qt installers from qt.io. Make sure to specify the correct path to 
your installed Qt 5 by setting CMAKE_PREFIX_PATH to the directory which 
contains the bin folder of the Qt installation (not the bin directory itself!). 
If you still want to use the 2014.10 release and the correct Qt 4 wasn't found 
by CMake, you can change the QT_QMAKE_EXECUTABLE variable to point to the right 
installation of Qt 4.

Best,
Stefan

Subject: Re: [mitk-users] Qt version in the template project

So now I have two related problems. I would like to have the MITK application 
(for some everyday image visualization) and I also want to create my own 
MITK-based app. For the first, I thought the best would be to build the latest 
release. For the second, I would like to start by the project template.

Overall it all comes down to the following question: if I do not intend to 
develop MITK itself, but use it and build my own app, shall I use the latest 
release, i.e. 2014.10? If so, shall I use Qt4 or Qt5?

More precisely,

1. Building MITK:

I go to [1] which I thought were ther instructions for the latest release. 
There it says

You need:
...
3. Qt<http://qt.nokia.com> 4.x if you plan to develop Qt-based applications 
(version 4.7 or above is required, Qt 5.x is only supported experimentally for 
a very limited number of modules)
...

So does this mean that If I want to use the stable release I should use qt 4? 
Because I have downloaded
the MITK-2014.10.0-src.tar.gz file, and it allows me to choose Qt4 or Qt5. If I 
use Qt4 it unselects USE_Blueberry because it is not compatible with Qt4. As a 
result, I do not get the MITK Workbench application (which I want) built.

2. Building MITK Project Template:

I downloaded the version you suggested [2] but it is automatically detecting 
Qt4 and in the CMake list there is no flag to select the desired version. So 
should I just stick to Qt4 here or am I doing something wrong? I need Qt4 for 
other stuff so removing from the system is not an option.


Sorry if these questions are too trivial but I think I need some help to get 
started. Thanks a lot for your help!

Alberto

Hi,



BTW the build instructions were just updated a few days ago, especially 
regarding Qt 5 (never mind if you are using our last release 2014.10). However, 
you must use the new nighlty URL (nightly instead of nightly-qt4) for 
developments based on the current master. If you remember where you clicked on 
our website to still get to the old documentation, please give us a hint and 
we'll fix it, thank you. :)



It is still possible to use Qt 4 by setting the CMake variable 
DESIRED_QT_VERSION from 5 to 4. However, we strongly recommend to use Qt 5 
unless you are working on Mac OS X. There are currently still Qt 5 related bugs 
which make it nearly impossible to use the Workbench on that platform as 
intended. Be warned, this is the only reason that we keep Qt 4 portability. As 
soon as these issues are resolved, we will completely drop Qt 4 support.



Best,

Stefan

Betreff: Re: [mitk-users] Qt version in the template project



Hi,



Rostislav is right, you probably used the tip of the master branch of the 
MITK-ProjectTemplate repository. This is synced with the master branch of the 
MITK repository.



Unless you explicitly need the development version (master branch), you should 
use the MITK 2014.10 release and this link [1] for the MITK-ProjectTemplate 
with that release.



The link to the build instructions (with nightly-qt4 suffix) is deprecated and 
the new version is here [2] which mentions Qt5. It looks like we missed 
changing a reference to the old documentation somewhere.



Best,

Sascha

Hi Alberto,



I believe you're using the latest release 2014.10. So you will need the project 
template synced with this version. One way to get it is to find the commit that 
mentions this release version and use that as your project template.



Rostislav.

Dear all,



I am trying to get started with building my first MITK application. I am 
confused about the QT version though. In am using Ubuntu 14.04 64b



In the website 
here<http://docs.mitk.org/nightly-qt4/BuildInstructionsPage.html#BuildInstructions_Prerequisites><http://docs.mitk.org/nightly-qt4/BuildInstructionsPage.html#BuildInstructions_Prerequisites>
 it says QT 4.x preferred, however when I download the tarbal from 
here<https://github.com/MITK/MITK-ProjectTemplate><https://github.com/MITK/MITK-ProjectTemplate>
 and run CMake, it seems to be looking for QT5. In 
here<https://github.com/MITK/MITK-ProjectTemplate><https://github.com/MITK/MITK-ProjectTemplate>
 it actually says QT 5.0 or newer, so I wonder if it is still possible to build 
using 4.7+ in linux? Is it "advisable" to use Qt5.0 instead?



Thanks,



Alberto
