due to problems in the glade packaged for Ubuntu. I decided to build the latest version (3.20). I also had to compile the gtk + 3.20. Then I realized that some components were strangers.
What went wrong?
The problem is my gtk theme :-\

I installing Qt open source framework in my window 10 pc. I already downloaded Mingw compiler and installed it to write C/C++. Now I wanna learn QT framework. I using Qt online installer. I choice to download custom compoment. Do I need to selet mingw component to download if i had already installed?
Note that there's not just one MinGW distribution and version out there. You can check out the exact supported version per Qt release at https://wiki.qt.io/MinGW .
Anyhow, if you install the pre-built Qt binaries via the online installer, the matching MinGW version will automatically be installed for you, and will be registered in Qt Creator so that things just work. There is actually no official way to prevent this.
I know that there're many questions regarding this aspect:
QML module not found (QtCharts)
How to include the QtCharts library in Qt Creator 4.2.0 (Community)
How to fix "QtCharts" library file not found/can't include <QtCharts>?
Importing QtCharts in QML causes module not installed error
Many more...
But most of them solve this issue by adding QtChart in Qt Maintenance tool, and I've already done this (and re-checked it).
But when using it:
QT += charts
I still received the Unknown module(s) in Qt error.
I've already asked this question in forum.qt.io, (and as I was asking, this question received no satisfactory answer, so please don't judge me if an answer is found on the forum by the time you answer this question), and some people said that I need to install and build the module first.
If this is the case, how do I do it? If not, what should I do with this? I'm thinking of reinstalling Qt and adding the module immediately when installation occured.

Some system info:
Windows 10, 64 bit
QtCreator 4.15.1
Qt 5.12.2 (MSVC 2019, 64 bit)
It seems you have only installed Qtcharts in the Additional libraries section.I know it's showing 0mb installation which is useless.
Select the QT section which is below the additional libraries section. Then select the version you have installed. Under the selected version there is a QT charts module, select it and install that.
Then go to your project and run a 'qmake'. Now you can observe all the errors are gone.
I had the same problem and I uninstalled and reinstalled Qt with QTChart. But the problem was not solved.
Accidentally, after installing Qt5, I used the following command to uninstall Qt4 libraries, and the problem was solved!
sudo apt purge qt4*
I'm trying to compile and run an application on a MacBook using Qt Creator. There are no issues compiling the project, but when I try and run it, it seems to be unable to load a plugin.
Could not load the Qt platform plugin "cocoa" in "" even though it was found.
The application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
This error occurs both when trying to run the application from Qt Creator or via Finder. It seems to only happen when I use the CMake build system (no issues when using QMake), but my existing project that I need to deploy on MacOS uses CMake.
My steps to reproduce are:
Install a completely clean MacOS (no user data)
Install Xcode 11
Install CMake 3.15
Install Qt 5.13.1 MacOS package
Open QtCreator->New Project->Qt Quick Application - Scroll
Set build system to CMake (important)
Compile and notice error
I am using:
Qt 5.13.1
macOS Catalina 10.15
Apple Clang 11
I recognize that for final user deployment I will need to use the macqtdeploy tool to copy the Qt libraries to the executable folder, but I should be able to run my app from QtCreator without doing this? Especially as it works fine when using QMake.
So it ended up being some kind of name resolution thing where Qt Creator couldn't decide whether to use the debug or release versions of the framework. Supplying DYLD_IMAGE_SUFFIX=_debug fixed this (add this to the environment section under Kits).
I a Qt neophyte so I apologize in advance if this question is obvious...
I just downloaded and installed the latest version of Qt Creator 5 as well as Qwt (Qt Widgets for Technical Applications) on my Windows7 machine.
Qwt.pro does not build using QT Creator on my windows machine.
It all worked fine on my Ubuntu machine using Qt Creator 4.
Is there a compatibility issue with Qwt and the newest version of Qt??
Have you installed the MinGW version Qt? If not make sure you have installed Visual Studio, which contains the MSVC compiler. To get started use the MinGW version, the MSVC compiler is faster on Windows but more complicated to set up. For testing run qmake in your Qwt directory directly from the Qt console (start menu). Also make sure you can build a simple hello world project with Qt Creator first.
We have a Windows7 VS2008 C++ app that uses both ITK 3.10.1 and Qt 4.5. We run CMake 2.6-patch 4 to generate both ITK and our app C++ projects, and everything run OK.
Now I switch to ITK 4.1.0, and to do this I had to upgrade CMake from 2.6 to 2.8 and generate ITK 4.5 and our app with this CMake. Now ITK compiles OK, but the app does not. The error dialog reads "There is no Qt version assigned to this project for platform Win32. Please use the 'change Qt version' feature and choose a valid Qt version for this platform.".
The platform was Win32 and still is; the computer is the same, and I did not touch Qt. Obviously I did not do something that should be done or did something that should not.
Any help will be highly appreciated.
Regards.
