Getting Started on Linux¶
Qt package from here or a custom build of Qt 5.12+ (preferably 5.15)
A Python interpreter (version Python 3.5+ or Python 2.7). You can either use the one provided by your OS, or get it from the official website.
CMake version 3.1 or greater
Git version 2 or greater
libclang from your system or the prebuilt version from the
Qt Downloadspage is recommended. libclang10 is required for PySide 5.15.
sphinxpackage for the documentation (optional).
Depending on your linux distribution, the following dependencies might also be required:
Building from source¶
Creating a virtual environment¶
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 set the environment variable required:
7z x libclang-release_100-based-linux-Rhel7.6-gcc5.3-x86_64.7z export LLVM_INSTALL_DIR=$PWD/libclang
Cloning the official repository can be done by:
git clone --recursive https://code.qt.io/pyside/pyside-setup
Checking out the version that we want to build, e.g. 5.15:
cd pyside-setup && git checkout 5.15
Keep in mind you need to use the same version as your Qt installation.
git checkout -b 5.15 --track origin/5.14 could be a better option
in case you want to work on it.
Check your Qt installation path, to specifically use that version of qmake to build PySide2.
Build can take a few minutes, so it is recommended to use more than one CPU core:
python setup.py build --qmake=/opt/Qt/5.15.0/gcc_64/bin/qmake --build-tests --ignore-git --parallel=8
To install on the current directory, just run:
python setup.py install --qmake=/opt/Qt/5.15.0/gcc_64/bin/qmake --build-tests --ignore-git --parallel=8
You can execute one of the examples to verify the process is properly working. Remember to properly set the environment variables for Qt and PySide2:
