Build qt from github

Wednesday December 18, by Cristian Adam Comments. GitHub Actions currently offers the following virtual machines runners :. Qt SDK is not part of the software installed on the runners. This is not a problem since we want to build with the same Qt version that Qt Creator itself was build.

In order to download files, to extract them, and to start compilation I decided to use a scripting language that is installed on all three of them: CMake in scripting mode via -P command line argument. At the end we will have a shared library. On git push the plugin will be built and the artifacts stored on every build.

This looks like this:. If we tag a commit with git tag -a v0. This looks like:. GitHub Actions has some differences in platforms and compilers when it comes to how Qt and Qt Creator are built:. As it turns out Qt Creator was able to load the plugin on all three platforms! Download the latest release here: www.

You don't need to compile Qt Creator in order to develop a Qt Creator plugin. GitHub Actions currently offers the following virtual machines runners : Ubuntu Triggering GitHub Actions On git push the plugin will be built and the artifacts stored on every build.

For Linux, it is recommended to download from your package manager instead of using the standalone version. A: You need to have a compositing window manager set up and enabled. Penguin Subtitle Player is a Qt5 project. The executables include statically compiled Qt libraries. Check here for deployment details. In case you would like to deploy a version which does not require Qt libraries in the client's system, consider statically build Qt then qmake with the static option, or change the config line in PenguinSubtitlePlayer.

Deployment of dynamically linked Qt applications always was is not a trivial task. While everything works on your development machine, being deployed on another machine your applications most likely will complain about all sorts of missing libraries. What I did in the past - I just copied the entire set of Qt libraries to the application directory and then application started working.

But, first of all, copying just Qt libraries is not enough, there are some other libraries that need to be deployed along, and secondly, the final size of the deployed application can easily exceed a couple of hundreds of megabytes, which is not really okay even for desktop targets, not to say about embedded devices with quite a limited space available.

Having built your application statically linked, you get everything all-in-one - a single executable file which is very easy to deploy and it will have a smaller size comparing with its dynamically linked equivalent. However, if your deployment target has several Qt-based applications, then static linking is not that attractive in terms of saving space, because in case of dynamic linking every Qt-based application can use the same set of shared Qt libraries, which you need to deploy only once.

Speaking about security - that one usually references to the fact that application relying on shared libraries is easier to hack because you can replace libraries with the modified ones.

And also as far as I know it is possible to sign shared libraries and perform checks before actually calling them. Be aware, that if you are using Qt under LGPL, then using static linking might make it harder for you to comply with the license terms and keep your code private at the same time. It is actually embarrassingly easy. You only need to run the configure utility with the right set of parameters. The first step is the same for all platforms: create a folder for shadow build and run configure command from there:.

The set of options can differ from platform to platform. In my case it was the same for Mac and Linuxbut for Windows I had to add two additional ones. Full list of all possible options you can find in the documentation. Or you can get it from configure itself. Core options section refers to 3rd-party librariesand quite often I see in different places people putting options like -qt-zlib-qt-libpng and so on for configure. You can check which ones exactly are set in the configure summary output after you run it.

So, you ran configure and now it asks you which edition you would like to build and also if you accept the license these two are also available as options for configure :. Now you need to actually build it. So, if you, like me, have 8 cores in your CPU 4 physical and 4 logicalyou can run it like that:.

With -j8 provided, it took 32 minutes to build Qt statically on my MacBookPro with 2. I have Linux on Lenovo Tp laptop with 2. After executing the last step make -j8 install you will get your static Qt in the folder specified with prefix parameter.

I was trying to build Qt on Windows from time to time, and usually it fails, but sometimes it actually does build. First I tried to do it with Qt 5. I wanted to investigate that, but then suddenly Qt 5. So I added -opengl desktop to the list of configure options. So, the final command line now looks like this:.

I executed it and after a while like, 10 times slower than on Linux I got the following output:. I tried setting flags in qmake. So I installed Qt to another machine with Windows and tried to perform configure. There it gave me a different type of error:. It asked me about edition, I chose commercial, and….Qt binaries and packages are available on the Qt website or can be built from source code. CMake is a platform independent configuring system that is used for generating Makefiles,Visual Studio project files, or Xcode project files.

Once you have configured and generated, you can build in a command prompt. The console version ccmakeor GUI version can also be used.

You may be prompted to specify your location of the Qt installation. If you installed Qt in the default location, it should find Qt automatically. After configuration is done, generate the make files or project files for your favorite development environment and build.

OpenAL Optional. XAudio2 is always used. Windows 8 and later natively supports XAudio2. For Windows 7 and older, you have to install the driver from DirectX to run. On Windows you must put mingwmake. OpenAL recommended or PulseAudio.

Otherwise you will get an error when running qmake. If they are already be where they should be, for example you install from apt on ubunt, just skip this step. It's the simplest and best way. Qt include and lib dir are always searched in QtAV. If using OSX and your ffmpeg is installed via brew brew install ffmpegyou can:. Then qmake will create a cache file.

Find the sources on Github. Automated builds will run weekly, thus changes in the underlying base images will reach the registry within that time.

Due to a build time limitation of 3 hours with travis ci, I unfortunately am not able to provide qtwebengine with my builds. Once I either get help with transferring the build pipeline to another platform, where the time limitation is not that strict, or once travis give their VMs more cores for build jobs so that the build fits in 3 hours, I can include qtwebengine in my builds.

Until then, you have to build the image locally with the provided script description below and adjust the build config if you absolutely need it. Provide your qmake project that you want to build in a separate directory and build it with qt-build :.

You will find your built project in a new sub directory named build in your project directory. The latest -tag will give you the latest released qt version for your build environment. For different versions available, refer to the available tags -section. Generally you will find full version tags like 5. There will be some tags listed that are named like builder-x. Those images are used for ci builds of the images and contain the whole qt source overhead.

They are used as caches in the ci environment. You normally do not want to use them for any production stuff, because they are fairly large. However, you can get an interactive session as well for manual adjustments or examinations:. If you pass additional arguments to build they will be taken into account as arguments to qmake which allows you to modify your build if needed.

Replace X,Y,Z according to your desired qt version. You have to provide a build configuration as a very simple configure -script in the buildconfig directory to make the build succeed. The script has to be named after your desired QT version, e.

Example content:. The build arguments can entirely be omitted, resulting in a build with some default values from the Dockerfile. However, I do not promise that those default values for the Qt -Version that are hardcoded in the Dockerfile will get updated on a regular basis, because I inject the desired versions all in my ci build matrix.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
