    I have a fresh install of Felgo 2 and when I build/run any project, whether it’s a new one from a template or from the source code of one of the sample (Component Showcase for example) I only get this :

    :-1: erreur : collect2: error: ld returned 1 exit status

    I made sure I already installed the dependencies :

    sudo apt-get install g++ libglu1-mesa-dev libgstreamer-plugins-base0.10-0 build-essential

    I tried deleting the FelgoSDK folder and running the installer again with no success.


    Could anyone help me ?



    Edit :

    sudo apt-get install libpulse-dev Fixed it !

    Hi, I’m trying to compile v-play examples and it produces the error:

    Invalid json file: /home/ppx/FelgoSDK/Examples/Felgo/appdemos/Error in ” Util.asciify(“build-Showcase-Android_for_armeabi_v7a_GCC_4_9_Qt_5_8_0-Debug”)”: TypeError: Property ‘asciify’ of object Core::Internal::UtilsJsExtension(0x2a1e430) is not a function/android-libShowcase.so-deployment-settings.json

    Hi Reynier!

    The problem might be related to long project paths, which sometimes is an issue when building on Windows.

    Can you try to change the default build path to a short location?
    You can change the build path for your project in the Qt Creator “Projects” tab.

    Hi Reynier,

    what Linux version are you using?

    Does this issue also happen when you try to create & run a new project on Android (File / New Project / Empty Felgo Application) without any plugins?

    Cheers, Chris

    pls help

    cannot find missing dependancy qt59 win 64 msvc for vplay




    Hi Pushpit,

    You saw this error message due to server issues we experienced in the past days.

    Please try to run the installer again and you should be good to go!

    I’ve downloaded & installed v-play today, however I’m stuck on this screen…

    (btw: my user, email & passwd are correct… I’ve tested the usr:pass in the web page)

    Hi Marco,

    Is there any progress after tapping the “Login” button?

    Hi guys,

    Well you knew that if someone was going to have a problem installing the latest Felgo update then it would be me!

    I just tried updating to v 2.13.2 and very carefully followed the installation instructions because I know I always seem to break it somehow…

    Anyway – I updated the engine, then I ran the maintenance tool again and selected the Qt 5.9.2 android components, I chose the new Android kit in Qt Creator and lastly updated my android/build.gradle file.

    After all that, when I try to run my project on Android I get the following error in compilation:

    ..\TankzOFFLAPTOP\main.cpp:1:24: fatal error: QApplication: No such file or directory

    #include <QApplication>


    compilation terminated.

    Makefile:438: recipe for target ‘main.obj’ failed

    mingw32-make: *** [main.obj] Error 1

    22:43:02: The process “E:\FelgoSDK\Tools\mingw530_32\bin\mingw32-make.exe” exited with code 2.

    Error while building/deploying project Tankz (kit: Android for armeabi-v7a (GCC 4.9, Qt 5.9.2 for Android armv7))

    When executing step “Make”


    Sorry for breaking it AGAIN! Please help….

    Hi Darren,

    you are not at fault! 😉

    When installing / uninstalling components with the MaintenanceTool it sometimes does not update / load some packages correctly. The error

    ..\TankzOFFLAPTOP\main.cpp:1:24: fatal error: QApplication: No such file or directory

    indicates that the Build Kit you are building with does not contain the Felgo libraries -> so the MaintentanceTool added the new Qt 5.9.2 Android Kit, but failed to install the Felgo libs.

    Can you try removing and re-installing the Android Kit again to see if the tool correctly installs everything then?






    Ahhhh… you see, you’re not just a pretty face Günther!

    Your advice worked and got me past that step so I no longer receive the Felgo libs error.  Instead I get a new error (see below).


    I thought I would be clever and resolve it myself by updating my Android SDK Build Tools.  I have done that and updated my SDK Build Tools to v27 – which I can see there is now a 27.0.0 folder on my computer.  However I am still receiving the same error message below.  Do I need to change the setting in a file somewhere?  Or have I gone completely wrong?


    Thanks again, Darren.

    Hi Darren,

    The error indicates that you are using Build Tools 23.0.2, but the new SDK requires a minimum build tools version of 25.0.0.
    You can update your build tools with the Android SDK Manager (SDK Tools packages). I did a test with Android API version 27 and latest build tools version 27.0.0 – the Android build works fine with these versions.

    Can you have a look at your installed Android SDK build tools version?

    Before trying a new build, please fully clean the project / android build:

    • Close Qt Creator
    • Remove the shadow build directory (e.g. build-<app>-Android_for_armeabi_v7a-…) from your file system.
    • Remove the *.pro.user file in your project folder from the file system
    • Open the project in Qt Creator and select your Kits
    • Right click the project in Qt Creator and choose “Clean” followed by “Run qmake”
    • Build and run the project

    Do you still get the same issue with the exception and warning for a fresh and clean build?






    Thanks – that worked!

    I had correctly installed v.27 of the Android API, but had not removed the *.pro.user file or the shadow build directory.

    After completing that and following the rest of your steps it works perfectly!

    Thank you




    i have installed v-play on windows, the latest version.

    when i quit QT Creator and re open a project and try to run it, i get an error:


    Starting F:\qtprojects\build-TPServer-V_Play_Desktop_Qt_5_9_3_MinGW-Debug\debug\TPServer.exe…

    The program has unexpectedly finished.

    The process was ended forcefully.

    F:\qtprojects\build-TPServer-V_Play_Desktop_Qt_5_9_3_MinGW-Debug\debug\TPServer.exe crashed.


    also a new created project crashes immediatly

    i do not know what is wrong here.


    when debugging the app i get the following code:

    During startup program exited with code:






    when i run qtcreator in admin mode it works and i do not have any issues.

    don’t know how this can happen, but maybe i have broken some things on my windows 10 installation
