Qt project binary creator
This will take a while depending on the speed of your Internet connection. After downloads are completed it will start installing. Qt Creator will launch and show the Welcome screen. Qt Creator should auto-detect the Qt install and compiler and create a "kit" for desktop development. We can now test the installation by creating a simple project. Let's start with one for widgets: Pick Application and Qt Widgets Application: Pick the kit only one option is available then Next.
You can specify some more information. Pick the defaults unless you want to use something else. Pick no project management. You will now see the created skeleton application. You can look at the source code if desired: Click the hammer icon at lower left to build it. You can click on Compiler Output if you want to see it.
The project should successfully build. You can now click on the green triangle icon to run it. After doing so, it should launch and you will see a window named MainWindow come up.
You might also want to try a QML application. Build and run it as before. If the above steps worked you are all set up to develop with Qt on the desktop. You can now create your own applications from scratch or start with one of the many examples or tutorials available within Qt Creator.
Under the Start menu you will see a Qt section with entries for Qt Creator, as well as Assistant, Designer and Linguist in case you want to run these tools on their own. There is also an entry for a command prompt for Qt, which will have qmake and other tools in the path so you can work from the command line if desired.
If you want to go back and add or remove more Qt components, run "Uninstall Qt" which is the maintenance tool we used earlier. I hope that you now appreciate that setting up Qt for desktop development is easy and you can be up and running very quickly.
This example covered one of the most common setups. In the future I plan to continue this series for beginners, covering how to set up on a development environment on a Linux desktop and how to compile Qt from source. Read more articles from the category Qt QML. Skip to main content. More articles from the author. Assumptions and Prerequisites For this example I'll assume you are running Windows Installation Steps Fire up your web browser and go to http: Select to Add or remove components or Update components.
Summary I hope that you now appreciate that setting up Qt for desktop development is easy and you can be up and running very quickly. Create the binary folder, cd to that folder, then run cmake , specifying the path to the source folder on the command line. Specify the desired generator using the -G option.
If you omit the -G option, cmake will choose one for you. If there are project-specific configuration options, you can specify those on the command line as well.
The value of this variable is also stored in the cache so that it persists during subsequent runs. Other projects have different configuration options. On subsequent runs, instead of passing the source folder path to the cmake command line, you can simply specify the path to the existing binary folder. CMake will find all previous settings in the cache, such as the choice of generator, and re-use them.
You can view project-defined cache variables by running cmake -L -N. The GUI offers an interactive way to set cache variables. To use it, run cmake-gui , fill in the source and binary folder paths, then click Configure. It will then ask you to select a generator. After the initial configure step, the GUI will show you a list of cache variables, similar to the list you see when you run cmake -L -N. New cache variables are highlighted in red. If you click Configure again, the red highlights will disappear, since the variables are no longer considered new.
The idea is that if you change a cache variable, then click Configure, new cache variables might appear as a result of your change. The red highlights are meant to help you see any new variables, customize them, then click Configure again.
This will generate the build pipeline in the binary folder. You can then use it to build your project. Like the GUI, it lets you set cache variables interactively. It can be handy when running CMake on a remote machine, or if you just like using the console. CMake generates a Unix makefile by default when run from the command line in a Unix-like environment. Of course, you can generate makefiles explicitly using the -G option.
Assuming the source folder is the parent:. A single makefile is capable of building exactly one build type. To change to a different build type, you must re-run CMake and generate a new makefile. Once the makefile exists, you can actually build your project by running make. By default, make will build every target that was defined by CMakeLists.
You can also build a specific target by passing its name to make:. You can also parallelize the build by passing -j 4 or a higher number to make. CMake also exposes a Ninja generator. Ninja is similar to make , but faster. It generates a build. The Ninja generator is also single-configuration. Again, assuming that the source folder is the parent:. The above command line will generate a Visual Studio. There are no multiplatform. Build and run as you normally would. Note that CMake adds two additional targets to the solution: Like any Visual Studio solution, you can change build type at any time from the Solution Configuration drop-down list.
