Cura

Read this, it's important!

If you are reading this, then you are looking at the development version of Cura. If you just want to use Cura, take a look at the following location: https://daid.github.com/Cura

Development

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

Issues

Before posting issues (either Bugs, Feature requests or Requests for information) please read our policies carefully. These will be regulary updated and can be found at https://github.com/daid/Cura/wiki/Issue-policies

Packaging

Cura development comes with a script "package.sh", this script has been designed to run under *nix OSes (Linux, MacOS, FreeBSD). 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.

The "package.sh" script understands a number of envrionement variables defined at the top of the script. Review and adjust settings to match your needs.

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.

Fedora

Fedora builds Cura by using mock, thereby enabling it to build RPMs for every distribution that mock has a configuration file for. In pratice this means that Fedora can build RPMs for several versions of Fedora, CentOS and RHEL.

Cura can be built under a regular user account, there is no need to have root privileges. In fact, having root privileges is very much discouraged.

However, the user account under which the build is performed needs to be a member of the 'mock' group. This is accomplished as follows:

sudo usermod -a -G mock "$(whoami)"

To install the software that is required to build Cura, run the following commands:

sudo yum install -y git rpmdevtools rpm-build mock arduino

# Ensure that the Arduino tools can be found by the build
sudo mkdir -p /usr/share/arduino/hardware/tools/avr
sudo ln -sf /usr/bin /usr/share/arduino/hardware/tools/avr/bin

To build and install Cura, run the following commands:

# Get the Cura software, only required once
git clone https://github.com/daid/Cura.git Cura

# Build for the current system
cd Cura
./package.sh fedora

# Install on the current system
sudo yum localinstall -y scripts/linux/fedora/RPMS/Cura-*.rpm

Examples of building other configurations:

# Build for Fedora rawhide x86-64 and i386
./package.sh fedora fedora-rawhide-x86_64.cfg fedora-rawhide-i386.cfg

# Since only the basename of the mock configurations is used, this also works:
./package.sh fedora /etc/mock/fedora-21-x86_64.cfg /etc/mock/fedora-rawhide-i386.cfg

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 python-numpy python-serial python-setuptools python-wxgtk2.8 curl arduino

cd Cura

./package.sh debian_amd64          # or debian_i386 for 32bit
# this will prompt for your root password to run dpkg-deb

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.

We assume you already have Apple hardware with 64bit processor and you are familiar with tools like virtualenv, virtualenvwrapper and pip. Also ensure you have modern compiler installed.

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.

Configure Virtualenv

Create new virtualenv. If you have virtualenvwrapper installed: mkvirtualenv Cura

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-2.9.4.0/:

  1. cd into ~/Downloads/wxPython-src-2.9.4.0/ 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

  2. make install Note to speedup the process I recommend you to enable multicore build by adding the -jcores flag: make -j4 install

    Chances are high that compilation will fail with type mismatch error in Obj-C code. If it's the case then apply a patch at scripts/darwin/wxPython-src-2.9.4.0.patch. If it won't fix all the errors, just modify source files manually by casting types to those expected by clang.

  3. cd into ~/Downloads/wxPython-src-2.9.4.0/wxPython/

  4. Build wxPython (Note python is 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

  5. Install wxPython (Note python is 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

  6. 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

Install Arduino.app

Arduino.app is required to compile certain components used by Cura. Tested version on Mac OS X is 1.0.5 but recent releases should also work.

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: ./package.sh darwin

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.

FreeBSD

On FreeBSD simply use the Port Tree (cd /usr/ports/cad/cura) to create (make package) and install (make install) the package as root. Port will check for all necessary dependencies. You can also use the provided binary package with pkg install Cura.

If you want to create an archive for local use the package.sh freebsd script (as an ordinary user) will give you a tarball with the program.
