    bq. You can display pictures directly in your post

    I first did, but the picture is going in front of the profile.

    Ok, i've finally found and "run qmake". But the problem persist, I still have the error :
    “The entry point of procedure ?doItemsLayout@TableView@@UAEXXZ is not found in the dynamic library QtGui4.dll”

    Hmmm...

    Looks like a mix up of dlls. Do you have several Qt versions on your machine?
    How do you start in release mode? Through creator?

    Saw your reference to mingwm10.dll in your first post. Do you mix mingw and msvc compilations?
    That is not going to work for sure. The binaries are not compatible. Also you cannot mix between versions of the same compiler (within versions of msvc or within versions of mingw).

    You can see the parameters of my compilation above. I guess by the following picture that I have two versions of Qt and I'm compiling with Qt Creator.

    Sorry, I don't know.

    Those are the ones assigned to your project.

    Go to "Tools"->"options"->"Build&Run" there you find the different "Qt versions", "Compilers" and "Kits" recognized by Qt creator.

    For your project handling you should do a complete rebuild of the project. Same place as you found "Run qmake" there should be "Clean" and "Rebuild". It would be good enough to run rebuild, but clean before does not hurt.

    This wont affect my .cpp files ?

    I did, same error :
    “The entry point of procedure ?doItemsLayout@TableView@@UAEXXZ is not found in the dynamic library QtGui4.dll”

    I've found some topic on the same error on google, but I don't know what to do with it... It seems it come from the PATH environment :

    You have an old mingw version on your machine (3rd entry) not sure what is.

    "Clean" and "Rebuild" do affect only the generated files as .obj, libs, generated by the moc and ui stuff. You will keep your source. Otherwise something is completely wrong.

    Those posts are referring in principle also to a mix up of libs.

    You can check your environment path in a cmd prompt, by typing "path" and pressing return. Typically the output will be fairly long. Check whether there is an entry pointing to the msvc2008 you have on your machine.

    Alternatively, you can go also to the Build&Run page of your project. At the bottom is "System environment". There is also the "path" of the environment. Again no msvc2008 is allowed. You have only Qt libs compiled for msvc2010, so you can use only this compiler.

    Check also for references to the mingw build in path. They have to be out as well.

    Check, if the msvc2010 compiler tool chain is assigned to msvc2010 Qt libs. Your menu is looking different from mine and it is not only the language. I assume that you have an old qt creator version (cannot have a look right away), consider updating to the newest one.

    How can I update my QtCreator? I tried to update from QtCreator in Help>Start update tool and it says "No updates available".
    I think I've downloaded it from the nokia developpemer web site.

    You can download "Qt creator 2.8 from download page.":http://download.qt-project.org/official_releases/qtcreator/2.8/2.8.0/qt-creator-windows-opensource-2.8.0.exe

    You can also download and install "Qt 4.8.5 for msvc2010":http://download.qt-project.org/official_releases/qt/4.8/4.8.5/qt-win-opensource-4.8.5-vs2010.exe from there.

    AFAIK the nokia page is outdated already for some time. Probably you might get some maintenance stuff for Nokia mobile programming, but I do really not know.

    Your path setting looks fine to me. The only thing I am noting is the MikTex 2.9 setting. This caused problem in my setup some time ago. However, this is fairly late in the path setting and IIRC the path variable is used from start to end.

    One last "stupid" thought, you are not trying to compile as 64 bit app?
    All I saw on previous pages is referring to 32 bit, so there is only a little chance.

    How can I know that ? Why would it be a problem ?

    I've downloaded your links, I don't have debug and can only release, but anyway, I'm having the same issue. I'm compiling, adding QtGui4.dll, QtCore4.dll and mingwm10.dll to the directory, and I still have the entry problem. This thing is making me mad...

    What do I have to do with "Qt 4.8.5 for msvc2010" ? Anything dor the compilation ?

    Well well, this is working with the QtGui4.dll and QtCore4.dll of the new Qt Creator. Still, I'd like to understand what happened, what do I have to keep and what can I uninstall.

    The release is in 4.8.1 not 4.8.5, like the version you told me to download, how do I change it (if I have to, or do I uninstall it ?). When I remove the "mingwm10.dll" file from my release directory, it still work. So what is this file for ? What are the moc_file.cpp/.obj for ?

    I have an error with the new Qt creator 2.8 for the debug, to I have to parameter something ?

    For a release what do I need, only the .exe, the QtGui4.dll and QtCore4.dll ?

    Thanks a lot for your help ! ;)

    You cannot mix 32 bit and 64 bit compilations. You have to keep this separate.

    This would be yet another, but updated version of Qt libs. Just in case if anything is wrong with the other versions. This is fresh and presumably it has to work.
    It is your decision if you want to update or not.

    Do not copy dlls right away to the release folder where your exe is. When your compilation is correct, You can start it also as release in creator using the green arrow on the left. This runs only your application. It should make that all required dlls are found at their appropriate places. When I am doing this it has only the executable there.

    When you start copying dlls there, you might copy the wrong ones and we are doing the next circle.

    When you have checked that the release compiled version is starting correctly when pressing the green arrow button "run" on the left, you can enter the next step.
