How to build CuraEngine?

  • I've been trying to build CuraEngine on Ubuntu following the Github instructions.

    The problem is that it lists some requirements:

    • Clone the CuraEngine repository;

    • Install Protobuf (see below);

    • Install libArcus.

    I'm not sure where should I install Protobuf and libArcus. After several tries and locations I've received several errors during the build process.

    Does anyone have a more detailed guide on how to build this engine?

    This is not a direct answer, but a somewhat large workaround. Have you considered using OctoPrint? Most installations including Ubuntu, which I use, come with cura-engine installed. If not, it can be easily installed from the plugins menu in OctoPrint settings. OctoPrint is a really nice alternative to native software for various printers. I had the same struggle with Protobuf and libArcus and OctoPrint worked great.

    Have you tried installing using `sudo make install` in the protobuf and libArcus (after running cmake) directories?

    I've tried, but the build does not complete so it is impossible to run the install command.

    I'm assuming you actually want to build Cura, rather than simply install Cura. If you instead want to install Cura, you can try sudo apt-get install cura-engine

    The following instructions were tested on my own Debian 8 (Jessie) distribution; they should be mostly, if not entirely, the same, for Ubuntu. Note that I did not follow the exact steps as described on the github/Ultimaker/CuraEngine README.

    Before we begin, let's make a build directory and do everything in there.

    mkdir ~/Downloads/curabuild
    cd ~/Downloads/curabuild

    The instructions will be broken into

    1. Install dependencies

    Some or all of these may already be installed on your computer. To be sure, we install them anyways:

    sudo apt-get install git curl libtool dh-autoreconf cmake python3-setuptools python3-dev python3-sip sip-dev

    2. Install protobuf

    1. Clone and enter the protobuf git repository:

      git clone
      cd protobuf

    2. Build and install for C++:

      make # this will take some time
      sudo make install

    3. Install for Python 3:

      cd python
      sudo python3 install

    3. Install libArcus

    1. Clone and enter the libArcus repository:

      cd ../..
      git clone
      cd libArcus

    2. Build and install

      cmake .
      sudo make install

    4. Install CuraEngine

    1. Clone and enter repository:

      cd ..
      git clone
      cd CuraEngine

    2. Build and install

      cmake .
      make # grab a cup of coffee
      sudo make install

    5. Celebrate!

    If all went well, you're done! You can now use the Cura engine via CuraEngine. Enjoy.

    The objective is to build cura engine which runs from the terminal so I can run it from command line, will this end up on installing it without the GUI? That is the objective.

    This will not install the GUI. I believe `sudo apt-get install cura-engine` will not install the GUI either.

    This solved my issue with the install, thank you.

    I found I also needed `sudo apt-get install python3-sip-dev` otherwise libArcus would fail on the cmake step.
