Vertical grids management library and tools

At CMC

Build dependencies

• CMake 3.20+
• librmn

Environment

Load the right environment, depending on the architecture you need. This will load the specified compiler and its parameters, and set the EC_CMAKE_MODULE_PATH variable for the cmake_rpn modules.

• Example for ppp6/sc6 and icelake specific architecture:

. r.load.dot mrd/rpn/code-tools/latest/env/rhel-8-icelake-64@inteloneapi-2025.1.0

• Example for generic architecture on ppp6/sc6

. r.load.dot mrd/rpn/code-tools/latest/env/rhel-8-amd64-64@inteloneapi-2025.1.0

• Example for GNU on any architecture:

. r.load.dot mrd/rpn/code-tools/latest/env/gnu

You also need a version of librmn, and optionally tdpack: either load them from ssm, both are in rpn/libs domain (. r.load.dot rpn/libs/...), or provide the path to cmake install directories if you compiled them.

Build and install

For this requires to load rpn/utils (editfst,fstcomp)

and data at: ECCI_DATA_DIR/vgrid/1.9.b3/data_tests_res/vgrid_sample/{EC_ARCH}

And listing of each test will be in build/Testing/Temporary/LastTest.log

To isolate specific test(s), limit files under test/lib/src

Note that the vgrid_sample tests uses 'diff' to compare

If the diff fails, it will be shown above the line DIFF ERROR
