Symbol lookup error

[Vaishnavi_198]

I am trying to run a model in WRF version 4.3.1 on an HPC. The installation seems to be fine because I all the executables were created and was I able to run all the WPS programs, but when I try to submit a job using slurm scrip for real.exe I get the following error in the job.378599.err file that was generated.

Error: ./real.exe: symbol lookup error: ./real.exe: undefined symbol: __libm_exp_table_128

Note: No rsl files were generated.

I have attached the slurm script for job submission, the namelist.input and related script for sourcing various modules.

I resolved this issue!! The problem was the that I was sourcing compilers (in the env.sh -a script for sourcing and exporting environment variables) different from the one I used to install WRFv4.2.1 and the paths to netcdf and other libraries were not added in the "env.sh" for "$LD_PATH_LIBRARY and "$PATH".
