Installing Miniforge

  • CMOR 3.9.0 on conda-forge has support for Python 3.9, 3.10, 3.11, and 3.12.

  • Download the Miniforge installer for your system.
    • CMOR is currently only supported for Linux and macOS x86_64, and macOS arm64 (Apple Silicon)

  • Start the install with the following command

    bash Miniforge3-$(uname)-$(uname -m).sh

Creating the mamba environement with compilers and needed libraries

  • Depending on your os mamba brings different compilers

    For Linux

    export CONDA_COMPILERS="gcc_linux-64 gfortran_linux-64"

    For Mac

    export CONDA_COMPILERS="clang_osx-64 gfortran_osx-64"

  • Run the following command to build CMOR for your version of Python

    Python 3.11

    mamba create -n cmor_dev -c conda-forge six libuuid json-c udunits2 hdf5 libnetcdf openblas netcdf4 numpy openssl python=3.11 $CONDA_COMPILERS

  • Activate the mamba environment

    mamba activate cmor_dev

Configuring cmor

  • Depending on your OS linking environment variables are different

    For Linux

    export LDSHARED_FLAGS="-shared -pthread"

    For Mac

    export LDSHARED_FLAGS=" -bundle -undefined dynamic_lookup"

  • Set the PREFIX

    Since your environment can use a different name and its location is system dependent use:

    export PREFIX=$(python -c "import sys; print(sys.prefix)")

  • configure cmor:

    ./configure --prefix=$PREFIX --with-python --with-uuid=$PREFIX --with-json-c=$PREFIX --with-udunits2=$PREFIX --with-netcdf=$PREFIX  --enable-verbose-test
