BUILDING NDI

Prerequisite

• Git
• A C compiler
• A Fortran compiler
• CMake 3.12

Instructions

1. Acquire the source code On the internet, those with access to github can acquire the NDI source code using the Git version control system.

   git clone https://github.com/lanl/ndi.git
   

2. Establish your environment

   On LANL platforms, this can be accomplished using the environment module system.

   module load cmake
   module load <your preferred compiler vendor>
   

3. Configure your build

   cd ndi
   mkdir build
   cd build
   cmake [options] ..
   

   Optionally, the configuration can be customized by calling to the ccmake text-based interface or cmake-gui graphical user interface. Notably, when building with a static configuration build tool---such as GNU Make or Google Ninja---it's advisable to set the CMAKE_BUILD_TYPE variable to either Release or Debug, according to your use case. In addition, for those intending to install NDI, the installation directory can be specified by setting the CMAKE_INSTALLATION_PREFIX variable. See the CMake documentation for advanced usage.

4. Build the source

   cmake --build .
   

   See the CMake build tool documentation for advanced usage.

5. Run the tests

   ctest
   

   See the CMake testing tool documentation for advanced usage.

6. (Optional) Install the NDI library.

   cmake --build . --target install
