Obtain pre-built qt qtcreator binary files and use instantly without buildingcompiling
So for a 4 core system we might use:. This will take some time, anywhere from under an hour on a fast machine to many hours on a low-end computer. By default we are building all Qt modules, including some large ones like QtWebEngine, as well as all the Qt examples and demos.
I've found this can happen when building QtWebEngine, as it has some large files that require a significant amount of memory to compile. It is possible that the build can fail at this point due to some missing dependencies. If so, you will need to identify the missing packages, install them, and then continue building. You may want to use another location. If so, you can specify it using the -prefix command line option to configure. We haven't yet built the documentation, which will be available from Qt Assistant.
We can build and install it as follows:. Your new Qt install is ready to use. At this point you may wish to do some more testing, such as confirming that you can run some QML code using the qmlscene program. If you use the Qt Creator IDE, you should configure it to add the new Qt version and try building some of your own code or one of the Qt examples to verify that it works. I hope this tutorial has encouraged you to try building Qt on your Linux desktop.
One way to help the Qt project is to build and test Alpha, Beta, and Release Candidate builds — something you can do even if you aren't a Qt developer as long as you know how to build Qt from source. As I write this, Qt 5. Read more articles from the category Qt QML. Skip to main content. More articles from the author. Rationale Why would you want to build Qt from source? Basic Steps Here are the basic steps for building Qt on any platform: Download the source code archive.
Extract the source code into a working directory. Install the required development packages and other build dependencies for Qt. Configure Qt for the desired options and ensure that all dependencies are met. Install and test the new version. Ubuntu Example For this example will use bit Ubuntu desktop Linux version Download the source code archive I find the easiest way to download Qt version is to browse to the download server and navigate to the appropriate directory.
If you want to download the file directly from the Linux command line, you can use: If you want to verify that the download was not corrupted, you can generate an MD5 checksum of the file after you download it: Extract the source code into a working directory The next step is to extract the files from the source archive.
Install the required development packages and other build dependencies for Qt Qt is dependent on a number of tools and libraries. We recommend a MinGW-w64 based distribution with a recent gcc. Starting with Qt 5. Recommended package for 64 bit: Community member George Edison has cross-compiled Qt 5. The MinGW from http: The independent minGW-w64 project provides support for 64 bit, and also supports a much larger part of the Windows API.
The MinGW-w64 project however does not provide official binary builds: These can be grabbed either from the personal build directories of the developers the most popular being rubenvb , or from associated but independent projects like tdm-gcc or mingw-builds or msys2. Features different packages with cygwin, win32, win64, linux as host. Target is either win32 or win Packages are built with every GCC release, experimental and prerelease packages are built on request. Provides both packages with a bit and a bit compiler Windows host , that can also cross-compile to bit or bit.
Packages are available with both "posix" and "win32" threading libraries, for 32 bit also with sjlj or dwarf exception variants. Packages are by developer: A user has these options to choose from: You must ensure you use the same compiler used to build the Qt you use in order to avoid linker errors. You will probably need to accept the Windows dialog that requests permission to run the installer.
The installer will come up. If you have a Qt online account, enter the information here. If you want to create one, go ahead. Otherwise just select Skip to proceed. It will now download information about the available components from a remote server.
Pick the installation folder the default is normally fine unless you need more disk space on another drive. A path with spaces in it or that is very long may cause problems later, so avoid doing that.
Let's do a minimal install. If you want more components you can select them. I expanded Qt 5. The only other item I selected was under Tools, where Qt Creator 4. Next read and accept the license agreement. Then pick the Start menu shortcuts you want. The default is typically fine. Installation is now ready, so select Next. At this point it will download all the selected components. 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:
