Environment
- macOS Catalina 10.15.7
- miniConda 4.10.1
Build
Follow the guide from Installation from source
- Download and install miniConda as necessary.
- Setup conda virtual environment and install required packages.
conda create \
-n xeus-cling-dev \
-c conda-forge \
cmake \

cling=0.8 \
clangdev=5.0 \
llvmdev=5 \

- Activate the environment just created
conda activate xeus-cling-dev
- Configure required build variables
export CC=cc # which cc --> /usr/bin/cc
export CXX=c++ # which c++ --> /usr/bin/c++
- Make and change to build directory.
mkdir build
cd build
- Run
cmaketo generate make files
cmake \

Note that OpenSSL here locates in CONDA_HOME rather than in CONDA_PREFIX.
echo ${CONDA_HOME} --> /Users/nling/opt/miniconda3
echo ${CONDA_PREFIX} --> /Users/nling/opt/miniconda3/envs/xeus-cling-dev
Note:
OPENSSL_ROOT_DIRmust be configured, check FindOpenSSL for more details, in order to use a customized openssl version, otherwise, the linker(ld) will use macOS built-in OpenSSL by default, which is not allowed and will lead to linking errors as follows.

Note that you may need to install Jupyterlab if it's not yet installed.
conda install jupyterlab -c conda-forge
- Run Jupyterlab from the directory you would give Jupyter's File Navigator access to.
# pwd --> /Users/nling/opencv
jupyter-lab
- Create/Edit notebook with the target C++ kernels (C++11, C++14, C++17) just installed.
Problems
- Notebook run displayImage caused a crash
plt::figure();
plt::imshow(image);
auto pltImg = displayImage(image);
run displayImage(image) ended up with following crash.
Fatal Python error: init_import_site: Failed to import the site module
