Any help with this issue?

Hi Alan,

which Felgo version and which Qt version do you have installed, and which platform are you on?

Cheers, Chris

Hi there, I’m also having this problem on Windows 10 TP and Qt 5.3.2 MinGW 4.8.2 32 bit.

I just installed it via vplay installer and when I created a new project I got this error.

 

I also got an error on QApplication not found so I added “QT += qml quick widgets” to the pro file.

 

I didn’t get this error when testing on OS X.

Hi Tiago,

please use the latest Qt version 5.4 with Felgo, then the error will disappear.

Cheers, Chris

Ok, thanks.

I made a tiny modification to one of Qt dlls and I wanted to keep the version at 5.3, but it seems I will have to migrate it 5.4 anyway.

Thanks!

Hello, I have same issue. I’ve opened BalloonPop demo app in QtCreator (installed by Felgoer installer). All components are up to date, so qt 5.4 is used. I’ve also got an error on QApplication not found so I added “QT += qml quick widgets” to the pro file (same as topic starter).

Moreover, Qt 5.5 is downloaded by v-player sdk manager tool, but desktop config available only for 5.4.2

Hello,

Felgo version 2.5 already uses Qt 5.5, could you please make sure that this version is installed (it is selected by default if you’re using the Felgo Installer) and try to configure your project with a 5.5 target?

Thanks,

Alex

Hello Alex.

 

I’ve rechecked my Felgo installation and found that Qt 5.5 was installed only for Android platform. I’ve installed it for desktop as well and switch project in QtCreator to qt 5.5 desktop kit. But there are no changes here. Most strange thing, that everything was working some time ago. May be before I’ve updated to Qt 5.5 for Android platform.

Hello,

Can you check if there are some additional updates available in the Maintenance Tool? Otherwise a clean re-installation might help to solve the issue.

Best,

Alex

Old thread but I am getting the same error as the OP.
I am trying to get a blank v-play “Tabbed App” running.

../../../../VPlayTest/main.cpp:1:10: fatal error: ‘QApplication’ file not found
#include

Qt5.7 on MacOS using clang_64.

If I add to the project config
QT += widgets

It then errors with

../../../../VPlayTest/main.cpp:2:10: fatal error: ‘VPApplication’ file not found
#include

My other Qt projects run fine.

A newer thread fixed my issue

I’m running Qt 5.7 which seems to be the issue.
