Warning

Please note:

  • The Python 2 interface is no longer being developed and will be removed in Q1 2023.  
    Users are strongly advised to migrate to Python 3.

  • We have added an experimental CMake option to allow compilation of ecCodes with a C++ compiler. Try it by passing To enable this, pass the following to your the cmake command:
    -D ENABLE_EXPERIMENTAL_BUILD_WITH_CXX=ON
    This option is disabled by default.
