Python 3

The port of FreeCAD to Python 3 support is currently underway and progress is being tracked in this forum thread. The master branch of FreeCAD is already usable with python3. Tests are passing, but there are still many little incompatibilities. TESTERS WANTED!

This document is a placeholder for various platforms' build instructions and a checklist to monitor progress.

Ubuntu
The first step in building FreeCAD for Python 3 is ensuring you can build normally. Tip: It's also helpful to have a cmake GUI tool like cmake-qt-gui or cmake-curses-gui.

The following instructions are adapted from a post by looo in the Python 3 porting thread: Note: tested only with linux/ubuntu.

Download the current master of FreeCAD git clone https://github.com/FreeCAD/FreeCAD

If python3 is your default python then there shouldn't be much to do. If not I think the easiest is to do: Set the python relevant cmake variables with cmake-gui which are: - PYTHON_EXECUTABLE - PYTHON_INCLUDE_DIR - PYTHON_LIBRARY - PYTHON_BASENAME (=PySideConfigPYTHON_SUFFIX.cmake) -> for me on ubuntu this would be this: .cpython-35m-x86_64-linux-gnu - PYTHON_SUFFIX (=ShibokenConfigPYTHON_SUFFIX.cmake) -> eg.: .cpython-35m-x86_64-linux-gnu

Pivy
python3 builds for freecad are available with this ppa sudo add-apt-repository ppa:sppedflyer/mytestppa1 sudo apt-get update sudo apt-get install python3-pivy

Pysidse
PySide for python3.5 isn't officially available, but I think ubuntu provides a build. sudo apt-get install python3-pyside

Test builds on anaconda (linux64)
wget -c http://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh bash Miniconda-latest-Linux-x86_64.sh and follow the instructions

once miniconda is installed we have to configure conda to have access to the freecad-builds: conda config --add channels conda-forge conda config --add channels freecad now we create a new enviroment and install freecad conda create --name freecad_py3 python=3.6 freecad this will download all the necessary packages. When done activate the enviroment and start FreeCAD source activate freecad_py3 FreeCAD the first time you launch freecad, matplotlib loads some modules, and therefore FreeCAD will need some time to show up.

Conda
Install miniconda: http://conda.pydata.org/miniconda.html Install conda-build: conda install conda_build Add channels: conda config --add channels freecad conda config --add channels conda-forge Clone the current Python 3 port of FreeCAD git clone https://github.com/looooo/FreeCAD/tree/py3-27 Clone the conda-recipes for FreeCAD git clone https://github.com/looooo/FreeCAD_Conda - go to FreeCAD_Conda/.FreeCAD_debug - set the variables on top of the script (the path to FreeCAD, and if you want to build with calling cmake)

conda build. --python=3.6 --dirty (the dirty flag isn't necessary if you build the first time. If it isn't set conda does a full build all the time. The python option is not necessary if you have installed python3.6 miniconda version. But then you have to set this flag to build with python2.7....)
