* Prefer linking to `libhdf5.a` instead of `libhdf.so` by setting `HDF5_USE_STATIC_LIBRARIES=TRUE` * Setting `HDF5_NO_FIND_PACKAGE_CONFIG_FILE=TRUE` forces `find_package(HDF5)` [1] to return linker options in the form of `-lhdf5*`, which is what's expected by the `LIBS` arg of the ICON configure script [2] [1]: https://github.com/Kitware/CMake/blob/0bc5ae8c759288e8e3ab8cf5f0ffccd8b59ba54a/Modules/FindHDF5.cmake#L677 [2]: https://gitlab.dkrz.de/icon/icon-model/-/blob/release-2026.04-public/configure?ref_type=heads#L1804

@kgoergen We can now build ICON 2026.04 on JURECA and JUPITER. Note that this requires the NVIDIA compilers loaded via the # ICON CPU
./build_tsmp2.sh icon --ICON_SRC ${ICON_UPSTREAM} --no_update --clean_first --env env/jsc.2026.nvhpc.openmpi
# ICON GPU
./build_tsmp2.sh iconGPU --ICON_SRC ${ICON_UPSTREAM} --no_update --clean_first --env env/jsc.2026.nvhpc.openmpiAlso I did a recursive cd ${TSMP2_ROOT}/models
git clone -b release-2026.04-public --recursive https://gitlab.dkrz.de/icon/icon-model.git
ICON_UPSTREAM=$(pwd)/icon-2026.04 |
