macOS
=====
Requirements
------------
* `Xcode`_ 8.2 (macOS 10.11), 8.3.3 (macOS 10.12), 9 (macOS 10.13), 10.1 (macOS 10.14)
* ``sphinx`` package for the documentation (optional).
* Depending on your OS, the following dependencies might also be required:
* ``libgl-dev``, ``python-dev``, and ``python-setuptools``.
* Check the platform dependencies of `Qt for macOS`_.
.. _Xcode: https://developer.apple.com/xcode/
.. _`Qt for macOS`: https://doc.qt.io/qt-6/macos.html
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 # your interpreter could be called 'python3'
source testenv/bin/activate
will create and use a new virtual environment, which is indicated by the command prompt changing.
Alternatively, you can use the `uv`_ tool, which is popular in the Python community for Python
project management. The following command creates a virtual environment using `uv`_::
uv venv --python <python-version> testenv
source testenv/bin/activate
.. note:: Since the Qt for Python project still uses `setup.py` and not `pyproject.toml`, currently
`uv` can only be used as a replacement for `pyenv` for building Qt for Python. If you
have already the `.python-version` file (used by `pyenv`) in the project, make sure to
change the version to the `uv`_ Python you want to use.
Setting up CLANG
~~~~~~~~~~~~~~~~
If you don't have `libclang` already in your system, you can download from the Qt servers::
wget https://download.qt.io/development_releases/prebuilt/libclang/libclang-release_20.1.3-based-macos-universal.7z
Extract the files, and leave it in any desired path, and set the environment
variable required::
7z x libclang-release_20.1.3-based-macos-universal.7z
export LLVM_INSTALL_DIR=$PWD/libclang
Getting PySide
~~~~~~~~~~~~~~
Cloning the official repository can be done by::
git clone https://code.qt.io/pyside/pyside-setup
Checking out the version that we want to build, for example, 6.8::
cd pyside-setup && git checkout 6.8
Install the general dependencies::
pip install -r requirements.txt
For building the documentation::
pip install -r requirements-doc.txt
.. note:: Keep in mind you need to use the same version as your Qt installation
.. note:: With `uv`_, use ``uv pip install ...``
Building PySide
~~~~~~~~~~~~~~~
Check your Qt installation path, to specifically use that version of qtpaths to build PySide.
for example, ``/opt/Qt/6.8.0/gcc_64/bin/qtpaths``.
Build can take a few minutes, so it is recommended to use more than one CPU core::
python setup.py build --qtpaths=/opt/Qt/6.8.0/gcc_64/bin/qtpaths --build-tests --ignore-git --parallel=8
With `uv`_, this command becomes::
uv run setup.py build --qtpaths=/opt/Qt/6.8.0/gcc_64/bin/qtpaths --build-tests --ignore-git --parallel=8
Installing PySide
~~~~~~~~~~~~~~~~~
First, create the wheels using the `create_wheels.py`_ script::
python create_wheels.py --build-dir=/directory/where/pyside/is/built --no-examples
On successful completion, the wheels will be created in the `dist` directory.
.. note:: The `build-dir` typically looks like `build/<your_python_environment_name>`. The
requirement is that this `build-dir` should contain the `packages_for_wheel` directory.
If the `python setup.py` build command was successful, this directory should be present.
Finally, to install the wheels, use the following command::
pip install dist/*.whl
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/tetrix/tetrix.py
.. _`uv`: https://docs.astral.sh/uv/
.. _`create_wheels.py`: https://code.qt.io/cgit/pyside/pyside-setup.git/tree/create_wheels.py
