Read this, it's important!
If you are reading this, then you are looking at a custom development fork of Cura. If you just want to use Cura, take a look at : https://daid.github.com/Cura

Cura is developed in Python with a C++ engine. The part you are looking at right now is the Python GUI. The C++ engine is responsible for generating the actual toolpath. For development of the engine check out https://github.com/Ultimaker/CuraEngine

Cura development comes with a script "package.sh", this script has been designed to run under *nix OSes (Linux, MacOS). For Windows the package.sh script can be run from bash using git. The "package.sh" script generates a final release package. You should not need it during development, unless you are changing the release process. If you want to distribute your own version of Cura, then the package.sh script will allow you to do that.
Both MacOS and Linux require some extra instructions for development, as you need to prepare an environment. Look below at the proper section to see what is needed.
Debian and Ubuntu Linux
To build and install Cura, run the following commands:
git clone https://github.com/daid/Cura.git sudo apt-get install python-opengl sudo apt-get install python-numpy sudo apt-get install python-serial sudo apt-get install python-setuptools cd Cura sudo ./package.sh debian_amd64 # or debian_i386 for 32bit sudo dpkg -i ./scripts/linux/cura*.deb
Mac OS X
The following section describes how to prepare working environment for developing and packaing for Mac OS X. The working environment consist of build of Python, build of wxPython and all required Python packages.
###Install Python You'll need non-system, framework-based, universal with deployment target set to 10.6 build of Python 2.7
non-system: Output of
python -c "import sys; print sys.prefix"
should not start with "/System/Library/Frameworks/Python.framework/".
framework-based: Output of
python -c "import distutils.sysconfig as c; print(c.get_config_var('PYTHONFRAMEWORK'))"
should be non-empty string. E.g. Python.
universal: Output of
lipo -info `which python`
should include both i386 and x86_64. E.g "Architectures in the fat file: /usr/local/bin/python are: i386 x86_64".
deployment target set to 10.6: Output of
otool -l `which python`
should contain "cmd LC_VERSION_MIN_MACOSX ... version 10.6".
The easiest way to install it is via Homebrew using the formula from Cura's repo:
brew install --build-bottle --fresh Cura/scripts/darwin/python.rb --universal
Note if you already have Python installed via Homebrew, you have to uninstall it first.
You can also install official build.
Create new virtualenv. If you have virtualenvwrapper installed:
wxPython cannot be installed via pip, we have to build it from source by specifing prefix to our virtualenv.
Assuming you have virtualenv at ~/.virtualenvs/Cura/ and wxPython sources at ~/Downloads/wxPython-src-188.8.131.52/:
cdinto ~/Downloads/wxPython-src-184.108.40.206/ and configure the sources:
./configure \ CFLAGS='-msse2 -mno-sse3 -mno-sse4' \ CXXFLAGS='-msse2 -mno-sse3 -mno-sse4' \ --disable-debug \ --enable-clipboard \ --enable-display \ --enable-dnd \ --enable-monolithic \ --enable-optimise \ --enable-std_string \ --enable-svg \ --enable-unicode \ --enable-universal_binary=i386,x86_64 \ --enable-webkit \ --prefix=$HOME/.virtualenvs/Cura/ \ --with-expat \ --with-libjpeg=builtin \ --with-libpng=builtin \ --with-libtiff=builtin \ --with-macosx-version-min=10.6 \ --with-opengl \ --with-osx_cocoa \ --with-zlib=builtin
make installNote to speedup the process I recommend you to enable multicore build by adding the -jcores flag:
make -j4 install
Build wxPython (Note
pythonis the python of your virtualenv):
python setup.py build_ext \ BUILD_GIZMOS=1 \ BUILD_GLCANVAS=1 \ BUILD_STC=1 \ INSTALL_MULTIVERSION=0 \ UNICODE=1 \ WX_CONFIG=$HOME/.virtualenvs/Cura/bin/wx-config \ WXPORT=osx_cocoa
Install wxPython (Note
pythonis the python of your virtualenv):
python setup.py install \ --prefix=$HOME/.virtualenvs/Cura \ BUILD_GIZMOS=1 \ BUILD_GLCANVAS=1 \ BUILD_STC=1 \ INSTALL_MULTIVERSION=0 \ UNICODE=1 \ WX_CONFIG=$HOME/.virtualenvs/Cura/bin/wx-config \ WXPORT=osx_cocoa
Create file ~/.virtualenvs/Cura/bin/pythonw with the following content:
#!/bin/bash ENV=`python -c "import sys; print sys.prefix"` PYTHON=`python -c "import sys; print sys.real_prefix"`/bin/python export PYTHONHOME=$ENV exec $PYTHON "$@"
At this point virtualenv is configured for wxPython development.
Remember to use
python for pacakging and
pythonw to run app for debugging.
###Install Python Packages
Required python packages are specified in requirements.txt and requirements_darwin.txt
If you use virtualenv, installing requirements as easy as
pip install -r requirements_darwin.txt
###Package Cura into application
Ensure that virtualenv is activated, so
python points to the python of your virtualenv (e.g. ~/.virtualenvs/Cura/bin/python).Use package.sh to build Cura:
Note that application is only guaranteed to work on Mac OS X version used to build and higher, but may not support lower versions. E.g. Cura built on 10.8 will work on 10.8 and 10.7, but not on 10.6. In other hand, Cura built on 10.6 will work on 10.6, 10.7 and 10.8.
