The lts branch is the default branch that is cloned:. Note: init-repository is currently unable to initialize tags that are too old. An alternative way to build a specific release or branch of Qt5 although without linking of the gerrit account for code reviewing is to use git submodule update --init in place of the init-repository script. That translates to:. More information can be found in Get The Source. For more configure options, see Qt Configure Options.

A build script called configure or configure. You will want to call that script from a different, parallel-level directory, because unless you are using a Qt Autotest Environment you do not want to build Qt in the directory that holds the source code. Instead, you should use a "shadow build," meaning you should not build into the source directory.

The -developer-build option causes more symbols to be exported in order to allow more classes and functions to be unit tested than in a regular Qt build. It also defaults to a 'debug' build, and installs the binaries in the current directory, avoiding the need for 'make install'. The -nomake examples and -nomake tests parameters make sure examples and tests aren't compiled by default. You can always decide to compile them later by hand. ICU is required for building.

If you are using shadow builds, you must add this directory to your PATH , else no special actions need to be done manually in order to use them. To update both the qt5. In addition, you should pass the same parameters to init-repository as you did in Getting the source code. Unlike a "normal" git submodule update, this ensures that any changes to the module structure are automatically pulled as well.

It provides options for updating the repository, cleaning and building. Depending upon what changed in the source since it was last updated you might have to run configure again. The safe thing to do is to always run config. If you want to get the absolute latest stuff you can do so on a per-module basis, e. The -j 8 is because I have 8 'cores'. If I may add, you'd better do an out of source build so you don't "pollute" it with your build files.

It also allows you to use the same sources for different build e. Sorry for being a bit late for this thread but for sake of completeness and good information, I would rather expand than create a new thread. To my understanding, one should ensure proper "alignment" of submodules with superproject, by doing git submodule update --checkout --recursive after issuing command to check out specific tag.

When deciding which license to use, please check your corporate open source policy or consult a software licensing legal expert. Set up your local development environment, get the Qt source code from the repositories, and build the libraries on your machine.

Qt source code repositories are open to the public, which means that you can immediately help guide and shape the future development of Qt by contributing code, translations, examples and more. Find them in the Qt Online Installer. It will steer you to the right download version and help you install tools and add-on components that are available for your open source license. We believe in the Free Software movement where using software comes with certain rights, but also certain obligations.

Use of open source licensing gives users four primary degrees of freedom when using Qt applications or devices:. The Free Software community has thrived because of these rules, but there are also developers who never intend to observe these rules, and thus should get a commercial license. The Qt Company exists to support both sets with the dual offering. If you want to migrate from open source Qt to a commercial license, you should contact us directly to discuss about your options in practice.

Each application store has their own unique terms and conditions, which may or may not be compatible with distributing applications under LGPL or GPL licenses. The commercial license of Qt is compatible with the terms and conditions of all the leading application stores and thus typically the best choice for distributing a closed source application in various application stores.

Products distributed under the commercial version of Qt must also be developed under the commercial version of Qt. If you have already started the development with an open-source version of Qt and wish to move to a commercial license you need to have a written explicit permission from The Qt Company to facilitate this change. The Qt Company reserves the right to grant the permission at its own discretion.

If you are unsure of which license or version to use when you start development, we recommend you contact The Qt Company to advise you on the best choice based on your development needs. Yes, it is possible to use both LGPLv2. Doing this does not require changing license in either of the libraries, and it is possible to select a proprietary license for the application, if desired.

If LGPLv2. KDE is an international free software community, founded in , producing an integrated set of cross-platform applications for desktop and mainly known for its Plasma Desktop environment, which is provided as the default work environment on many Linux distributions. KDE software is based on the Qt framework.
