Installation fails using conda-based Python

[ThomasAuzinger]

I try to create a minimal docker image that runs the CGAL swig bindings. To manage the packages for the Python program, which ultimately uses these bindings, I use miniconda.

When building the following Dockerfile

FROM continuumio/miniconda3:latest
RUN apt-get update && apt-get install -y build-essential cmake git libcgal-dev libeigen3-dev swig
RUN cd /opt && git clone https://github.com/cgal/cgal-swig-bindings
RUN cd /opt/cgal-swig-bindings && mkdir build
RUN cd /opt/cgal-swig-bindings/build && cmake -DBUILD_JAVA=OFF -DBUILD_RUBY=OFF -DBUILD_PYTHON=ON -DCMAKE_BUILD_TYPE="Release" .. && make -j 4 && make install

The last line fails with a longer error message (see below), with the most relevant lines;

...
-- Found Python: /opt/conda/bin/python3.9 (found version "3.9.12") found components: Interpreter Development.Module
...
-- Found Eigen3: /usr/include/eigen3 (found suitable version "3.3.9", minimum required is "3.1.0")
CMake Error at SWIG_CGAL/Point_set_processing_3/CMakeLists.txt:6 (include):

    CGAL_Eigen3_support

CMake Error at SWIG_CGAL/Shape_detection/CMakeLists.txt:6 (include):
  include could not find load file:

    CGAL_Eigen3_support
...

I do not understand, why it does not find the file CGAL_Eigen3_support.cmake, which exists in the expected folder of CGAL. How would I solve this error?

Hi Thomas, the Docker image continuumio/miniconda3 is based on Debian Stable (version 11 "bullseye"). That version shipoed libcgal-dev version 5.2.

But current main version of cgal-swig-bindings is only assured to be compatible with CGAL-5.5.1 or later.

Instead of installing libcgal-dev using apt-get, clone it, that way:

FROM continuumio/miniconda3:latest
RUN apt-get update && apt-get install -y build-essential cmake git libeigen3-dev swig
RUN apt-get install -y libboost-dev libgmp-dev libmpfr-dev
RUN cd /opt && git clone --depth 1 https://github.com/cgal/cgal-swig-bindings && git clone -b v5.5.1 --depth 1 https://github.com/cgal/CGAL
RUN cd /opt/cgal-swig-bindings && mkdir build
RUN cd /opt/cgal-swig-bindings/build && cmake -DBUILD_JAVA=OFF -DBUILD_RUBY=OFF -DBUILD_PYTHON=ON -DCMAKE_BUILD_TYPE="Release" .. && make -j 4 && make install
