# PySide2 ### Introduction PySide is the [Python Qt bindings project](http://wiki.qt.io/PySide2), providing access to the complete Qt 5.x framework as well as to generator tools for rapidly generating bindings for any C++ libraries. The PySide project is developed in the open, with all facilities you'd expect from any modern OSS project such as all code in a git repository and an open design process. We welcome any contribution conforming to the [Qt Contribution Agreement](https://www.qt.io/contributionagreement/). PySide 2 supports Qt5. For building, please read about [getting started](https://wiki.qt.io/PySide2_GettingStarted). Then download the sources by running git clone https://code.qt.io/pyside/pyside-setup ### Building #### Dependencies PySide versions following 5.6 use a C++ parser based on [Clang](http://clang.org/). The Clang library (C-bindings), version 3.9 or higher is required for building. Prebuilt versions of it can be downloaded from [download.qt.io](http://download.qt.io/development_releases/prebuilt/libclang/). After unpacking the archive, set the environment variable *LLVM_INSTALL_DIR* to point to the folder containing the *include* and *lib* directories of Clang: 7z x .../libclang-release_39-linux-Rhel7.2-gcc5.3-x86_64.7z export LLVM_INSTALL_DIR=$PWD/libclang On Windows: 7z x .../libclang-release_39-windows-vs2015_64.7z SET LLVM_INSTALL_DIR=%CD%\libclang #### Build Instructions You might consider using a virtual environment as described at [getting started](https://wiki.qt.io/PySide2_GettingStarted). You should be able to build: cd pyside-setup python setup.py install The setup script will try to find the location of the qmake tool of the Qt version to be used and the cmake build tool in the path. Non-standard locations can be specified by the *--qmake=path_to_qmake* or *--cmake=path_to_cmake* command line options.
