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 update && sudo apt-get install -y dh-autoreconf cmake git
Additionally, protobuf requires python3-setuptools and libArcus requires
python3-sip-dev. Install them:
sudo apt-get install -y 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/v3.5.1/protobuf-python-3.5.1.tar.gz
tar zxf protobuf-python-3.5.1.tar.gz
Build and install for C++:
cd protobuf-3.5.1
./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
Copy executable to opt folder
mkdir /opt/curaengine && cp -a --no-preserve=owner ~/CuraEngine/build/CuraEngine /opt/curaengine/
Create a symlink to make it global executable
ln -s /opt/curaengine/CuraEngine /usr/local/bin/CuraEngine
Download default settings JSON files downloading a definition file,
cd /opt/curaengine/
wget https://raw.githubusercontent.com/Ultimaker/Cura/master/resources/definitions/fdmprinter.def.json
wget https://raw.githubusercontent.com/Ultimaker/Cura/master/resources/definitions/fdmextruder.def.json
try it:
CuraEngine slice -v -p -j /opt/curaengine/fdmprinter.def.json -o example.gcode -l example.stl --next
Hi, when I slice a file the file does not seem to centre itself on the bed. Even though I have changed the fdmprinter.def.json file to include the command line option and enabled the centre boolean value. this is the command I am using . CuraEngine slice -v -p -j /opt/curaengine/ender3.def.json -o /home/simar/cube.gcode -l /opt/stl_upload/cube.stl --next .
Any insight will be helpfull. I have also attached my def.json file.

Sorry for the pastebin, github was not letting my upload my file directly onto this post even though i modified it to be a text file.
