Error with libraries while running eclm.exe

[AdrienDams]

I am still trying to use eCLM on Levante. I came across this error when running eclm.exe :

(base) [a271098@levante6 1x1_wuestebach]$ ../../lib/bin/eclm.exe 
../../lib/bin/eclm.exe: error while loading shared libraries: libmkl_intel_lp64.so.2: cannot open shared object file: No such file or directory

Any ideas what I can do?

Have you loaded the necessary modules before running eCLM? It should be the same modules as those you used for building your model: https://github.com/HPSCTerrSys/eCLM/issues/13#issuecomment-1048577038

Here is the list of my modules

(base) [a271098@levante3 1x1_wuestebach]$ module list
Currently Loaded Modulefiles:

The issue is that the LD_LIBRARY_PATH is not being updated by the module load commands. The workaround is to manually set the LD_LIBRARY_PATH:

# Prepend paths to Intel MKL libraries
source $MKLROOT/env/vars.sh

# Prepend netCDF C library path
export LD_LIBRARY_PATH="/sw/spack-levante/netcdf-c-4.8.1-2k3cmu/lib:$LD_LIBRARY_PATH"

# Prepend netCDF Fortran library path
export LD_LIBRARY_PATH="/sw/spack-levante/netcdf-fortran-4.5.3-k6xq5g/lib:$LD_LIBRARY_PATH"

# Prepend parallel netCDf library path
export LD_LIBRARY_PATH="/sw/spack-levante/parallel-netcdf-1.12.2-mc24h4/lib:$LD_LIBRARY_PATH"

This solution is definitely not pretty; I would suggest that you ask Levante maintainers to update their modulefiles to include the LD_LIBRARY_PATH. module load is supposed to automatically set important environment variables so that the users don't have to.

It's fixed! Thanks a lot. I have also sent an e-mail to Levante maintainers about this issue.
