This project is a very simple example that shows how to use librmn in a client application with CMake.

It contains examples for C and Fortran.

CMakeLists.txt shows how to link the library with your application. This file is loaded with comments to explain what each CMake command does.

Requirements

• This only works with the development branch of librmn (20.1.0)
• The library must be accessible through one of the following means:
  • LD_LIBRARY_PATH, LIBRARY_PATH and CPATH must contain the paths to the library and headers
  • EC_LD_LIBRARY_PATH and EC_INCLUDE_PATH must contain the paths to the library and headers respectively (done when loading with r.load.dot/ssm)
  • rmn_ROOT can be specified in the CMake command line (-Drmn_ROOT=...) or as an environment variable. In both cases, it must contain the path to the installation root of the library under which lib and include can be found.
• If not building on ECCC's systems, git submodules must be retrieved: git submodule init followed with git submodule update --recursive

Building

1. Create a folder where to build the project mkdir /tmp/${USER}/librmn-client-example
2. Go inside the newly created folder cd /tmp/${USER}/librmn-client-example
3. Launch CMake on the path where this repository was cloned cmake <librmn-client-example clone path>
4. Launch make make
