Getting Started on Linux


  • GCC

  • sphinx package for the documentation (optional).

  • Depending on your linux distribution, the following dependencies might also be required:

    • libgl-dev, python-dev, python-distutils, and python-setuptools.

Building from source

Creating a virtual environment

The venv module allows you to create a local, user-writeable copy of a python environment into which arbitrary modules can be installed and which can be removed after use:

python -m venv testenv
source testenv/bin/activate
pip install -r requirements.txt  # General dependencies, documentation, and examples.

will create and use a new virtual environment, which is indicated by the command prompt changing.

Setting up CLANG

If you don’t have libclang already in your system, you can download from the Qt servers:


Extract the files, and leave it on any desired path, and then set these two required environment variables:

7z x libclang-release_100-based-linux-Rhel7.6-gcc5.3-x86_64.7z
export CLANG_INSTALL_DIR=$PWD/libclang

Getting PySide

Cloning the official repository can be done by:

git clone --recursive

Checking out the version that we want to build, for example 6.0:

cd pyside-setup && git checkout 6.0


Keep in mind you need to use the same version as your Qt installation. Additionally, git checkout -b 6.0 --track origin/6.0 could be a better option in case you want to work on it.

Building PySide

Check your Qt installation path, to specifically use that version of qtpaths to build PySide. for example, /opt/Qt/6.0.0/gcc_64/bin/qtpaths.

Build can take a few minutes, so it is recommended to use more than one CPU core:

python build --qtpaths=/opt/Qt/6.0.0/gcc_64/bin/qtpaths --build-tests --ignore-git --parallel=8

Installing PySide

To install on the current directory, just run:

python install --qtpaths=/opt/Qt/6.0.0/gcc_64/bin/qtpaths --build-tests --ignore-git --parallel=8

Test installation

You can execute one of the examples to verify the process is properly working. Remember to properly set the environment variables for Qt and PySide:

python examples/widgets/widgets/
