Cura by Dagoma was originally forked from Legacy Cura. It is built with the following components:

• LegacyCura
• CuraEngine
• Clipper
• Python 2.7
• wxPython
• PyOpenGL
• PySerial
• NumPy

Windows only :

• VideoCapture
• comtypes
• EjectMedia

The slicer binary is built on the fly. It is a full C++ project. The compilation process is based on standard Makefile.

For MacOS, it is necessary to use virtualenv and virtualwrapper to create a isolated python environment. Moreover, wxPython 3.0.1 sources has a bug impacting MacOS and a patch must be applied before compiling it. Check out the following bug opened against wxWidgets : https://trac.wxwidgets.org/ticket/16329

According to this :

• The wxPython github project has been forked under dagoma3d workspace : https://github.com/dagoma3d/wxPython
• A new branch named 3.0.2 has been created from the wxPy-3.0.2.0 tag
• The patch has been applied on this branch.

Finally, to build the software on MacOS, please follow the instructions described on LegacyCura : https://github.com/daid/LegacyCura/#mac-os-x

To build it on El Capitan, the commands must be slightly modified:

./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-macosx_arch=x86_64 \
 --enable-webkit \
 --prefix=$HOME/.virtualenvs/Cura/ \
 --with-expat \
 --with-libjpeg=builtin \
 --with-libpng=builtin \
 --with-libtiff=builtin \
 --with-macosx-version-min=10.9 \
 --with-opengl \
 --with-osx_cocoa \
 --with-zlib=builtin

python setup.py clean --all

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

python setup.py install \
 --force \
 --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

Here are the needed requirement:

• A gcc compiler (from mingw64)
• Nsis 2.51 (as the nsis script uses the InstallOptions plugin, available on 2.xx versions).
• 7zip 9.20 as extraction is handled differently with newer versions.

TODO: Modify (nsis and packaging) scripts so that we can use the lastest tools versions.

The needed binaries (eg. PortablePython) are retrieved and used during the packaging process so it must work pretty flawlessly.

For linux, two types of packages can be built:

• A debian package for Debian based distributions.
• A generic tar.gz archive for other distributions.

Nothing special is required for linux packaging, it should work natively.
