Stuck up in creating a Docker image for CuraEngine

[arnaudcosson 1]

Hi,

I am working on creating a docker image to have a centos machine with CuraEngine.

The purpose is to have an hosted instance to slice files from command lines.

I decide to base the image on centos because it is the distribution usually deployed in my compagny.

For install I followed instructions from https://github.com/Ultimaker/CuraEngine but I have an error with python version while installing libArcus.

Thanks for your help

Arnaud

You can just build libArcus without python.

Thanks nallath.

Any link to a how-to or some tips ?

[arnaudcosson 1]

To disable build with python on libArcus, simply change the line

option(BUILD_PYTHON "Build " ON) by

option(BUILD_PYTHON "Build " OFF) in CMakeLists.txt

Little up on this post, still not able to build curaEngine on my docker

             [args...]()
                  ^

My search on the net drives me to this conclusion:

I'm not able to compile CuraEngine because the version of the compiler that is used is not the good one.

But I didn't figure how to change it.

devtoolset-3-gcc was supposed to do the job...

 

Here is my updated DockerFile:

# Dockerfile for CuraEngine

FROM centos

#Global prerequisites
RUN yum install -y epel-release
RUN yum install -y libtool gcc-c++ wget unzip make devtoolset-3-gcc git

RUN mkdir -p /tmp/curabuild

    && wget -O protobuffv3.4.1.zip https://github.com/google/protobuf/archive/v3.4.1.zip \
    && unzip protobuffv3.4.1.zip \
    && cd /tmp/curabuild/protobuf-3.4.1/ \
    && ./autogen.sh && ./configure \
    && make -j4 \
    && make install

#Install Python 3
RUN yum install -y zlib-devel openssl-devel python34-dev

RUN cd /tmp/curabuild \

    && mkdir build && cd build \
    && ls -la .. \

You are using gcc-4.9. I just checked, but i'm building the engine with gcc 6.4.1

[arnaudcosson 1]

Thanks for the information. I will try with this version
