CuraEngine requires libArcus which requires protobuf. Let's build them in turn.
Make sure python3 is Python 3.4 or higher.
Install utilities used by the build process:
sudo apt-get install dh-autoreconf cmake git
Additionally, protobuf requires python3-setuptools and libArcus requires
python3-sip-dev. Install them:
sudo apt-get install python3-setuptools python3-sip-dev
I download everything to home directory and start from there. You may adapt to your preferred location.
Download protobuf's latest release.
Choose the one with Python. The filename should be like
protobuf-python-N.N.N.tar.gz, where N.N.N is the version number.
I use 3.1.0 as an example. You should use the latest version.
cd ~
wget https://github.com/google/protobuf/releases/download/v3.1.0/protobuf-python-3.1.0.tar.gz
tar zxf protobuf-python-3.1.0.tar.gz
Build and install for C++:
cd protobuf-3.1.0
./autogen.sh
./configure
make
sudo make install
Build and install for Python:
cd python
python3 setup.py build
sudo python3 setup.py install
Make sure shared libraries can be found:
sudo ldconfig
Clone repository:
cd ~
git clone https://github.com/Ultimaker/libArcus.git
Build and install:
cd libArcus
mkdir build
cd build
cmake ..
make
sudo make install
Make sure shared libraries can be found:
sudo ldconfig
Clone repository:
cd ~
git clone https://github.com/Ultimaker/CuraEngine.git
Build:
cd CuraEngine
mkdir build
cd build
cmake ..
make
There should be an executable CuraEngine in the directory. After downloading
a definition file, try it:
./CuraEngine slice -v -p -j fdmprinter.def.json -o example.gcode -l example.stl --next
I was building CuraEngine for a friend, and never used it myself. Sorry, can't help there. 😄
