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. – khaverim Jun 12 '16 at 01:24
  • Have you tried installing using `sudo make install` in the protobuf and libArcus (after running cmake) directories? – nanofarad Jun 15 '16 at 14:33
  • I've tried, but the build does not complete so it is impossible to run the install command. – Jorge Cuevas Jun 15 '16 at 20:38

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 https://github.com/google/protobuf
cd protobuf

  2. Build and install for C++:

    ./autogen.sh
./configure
make # this will take some time
sudo make install

  3. Install for Python 3:

    cd python
sudo python3 setup.py install

3. Install libArcus

  1. Clone and enter the libArcus repository:

    cd ../..
git clone https://github.com/Ultimaker/libArcus
cd libArcus

  2. Build and install

    cmake .
make
sudo make install

4. Install CuraEngine

  1. Clone and enter repository:

    cd ..
git clone https://github.com/Ultimaker/CuraEngine
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. – Jorge Cuevas Jun 21 '16 at 03:12
  • This will not install the GUI. I believe `sudo apt-get install cura-engine` will not install the GUI either. – Kye W Shi Jun 21 '16 at 03:44

    I found I also needed `sudo apt-get install python3-sip-dev` otherwise libArcus would fail on the cmake step. – Brian Stormont Jun 13 '18 at 04:56
