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 need to write Linux software for labs. Put on Virtual Box Mint (wrote that it is best for beginners fit). Installed QT Creator, like all the files needed downloaded. But in the end I still can not create a project.
Qt Creator is just the editor.
You still need to have at least one version of the Qt framework installed - either from an installer, built from source or from a package manager.
The installer bundles a copy (non optional) of Creator, configured to use it.
If you build from source you will have to add the Qt version (профили Qt) and make a kit (комплектьi) from it and a compatible compiler.
Using CMake to build both an app and plugin for it. Everything works fine on developer's PC, but on remote clean Linux Mint x64 installation there is an error:
plugin uses incompatible qt library Qt 5.3.1 [release]
Plugin and Application was build in release mode (actually I have tryed different combinations, with no luck)
I saw one guy here already asked about similar issue on Windows, but his question not answered.
Any ideas?
Problem fixed by exporting QML2_IMPORT_PATH and QT_PLUGIN_PATH, and copy dependebncies of Qt platform plugins (xcb)
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.
I've downloaded Qt 5.0.1 for Windows 32-bit (MinGW) and want to configure it again to support OpenSSL, but I can't find confiure.exe.
By the way, when I use Qt 5.0.1 command prompt to use configure, it says "configure.exe is not recognized".
configure.exe is part of the Qt's source code - so make sure you installed that.
But anyway i recommend you download the source code from here and start in a separate folder if you want to build Qt yourself (if you download the source make sure that you get the .zip from downloads, tar.gz is for linux use and doesn't have the Windows configure.exe)
I am working on Mac OS X at the moment, and wanted to start building apps using Qt Creator.
Unfortunately i can't build any applications as it gives me an error saying that qmake's path is not found or qmake is missing.
I tried using netbeans, which works perfectly with simple c/c++ programs, but for qt apps it then gives me the same error.
My version of Xcode 4 works perfectly and builds without any problems.
Any ideas?
Thanks :)
It is not enough to just download the Qt Creator, you need to download the complete sdk: http://qt.nokia.com/downloads (almost 1GiB)
My Macbook is no longer my primary computer. But, when it was, I found out through painful experiences that it was best to install software from MacPorts whenever what you wanted was available from http://www.macports.org/
Even more important, I also discovered that when software was not offered from MacPorts, it was invariably because that particular software did not install without some sort of tweaking on a Mac. Hence, since Macports does not currently offer Qt v5, and I had problems installing the qt-project.com Qt v5.2.1 SDK on my Macbook, I would advise to go with the MacPort for Qt v4.8.5 [qt4-mac] which includes qmake. Qt Creator is available as a separate MacPort [qt4-creator-mac].
Here is how I successfully installed Qt v4.8.5 [with qmake] and Qt Creator on my Macbook:
1) 'sudo port install qt4-mac'
2) 'sudo port install qt4-creator-mac'
3) I used Finder to run Qt Creator which was in the /Applications/MacPorts/Qt4 folder.
4) When I first ran Qt Creator, its Preferences dialog listed the auto-installed Desktop kit, but that kit had no Qt version, no qmake, and no debugger.
5) Manually added a second kit.
6) Configured kit's Qt version for /opt/local/bin/qmake, which is where qt4-mac installed qmake. This was enough for the kit to now discover Qt v4.8.5 which had been installed by qt4-mac.
7) Used kit's auto-detect feature to now discover the debugger.
8) Configured that kit to be the default kit.
