issue with shared library while using nodes

All things involving the setup (compiling, NetCDF, etc.) of the WRF Model itself.

issue with shared library while using nodes

Hi all,

I can run wrf.exe in the main machine, but when I try to use nodes, the following error message appears:
"./wrf.exe: error while loading shared libraries: cannot open shared object file: No such file or directory"

Actually, my system has two netcdf libraries and I want to use the netcdf library under /opt.
So, I added this specific path when I configured WRFV3.

-L$(WRF_SRC_ROOT_DIR)/external/io_netcdf -lwrfio_nf -lnetcdff -lnetcdf -I/opt/netCDF/include -L/opt/netCDF/lib -hdf5_fortran -lhdf5 -I/opt/HDF5/include -L/opt/HDF5/lib -lm -lz

Also, I added the netcdf into my bash file like:
export NETCDF=/opt/netCDF
export PATH=$NETCDF/include:$PATH
export PATH=$NETCDF/bin:$PATH
export LD_LIBRARY_PATH="/opt/netCDF/lib:/opt/intel/compilers_and_libraries/linux/lib/intel64:/opt/HDF5/lib:/opt/intel/impi/2018.1.163/intel64/lib:/opt/intel/lib/intel64:/usr/share/pvm3/lib"

Under /opt/netCDF/lib, I have So, wrf.exe should use not!

I also checked linked libraries to wrf.exe.
In the main machine:
$ ldd wrf.exe => /opt/netCDF/lib/ (0x00002b3c00573000) => /opt/netCDF/lib/ (0x00002b3c00b19000) => /opt/HDF5/lib/ (0x00002b3c03ec2000) => /lib64/ (0x00002b3c04481000) => /lib64/ (0x00002b3c04784000) => /opt/intel/impi/2018.1.163/intel64/lib/ (0x00002b3c0499a000) => /opt/intel/impi/2018.1.163/intel64/lib/ (0x00002b3c04d43000) => /lib64/ (0x00002b3c059c9000) => /lib64/ (0x00002b3c05bcd000) => /lib64/ (0x00002b3c05dd5000) => /lib64/ (0x00002b3c05ff2000) => /lib64/ (0x00002b3c063b5000) => /lib64/ (0x00002b3c065cb000)

In the one of nodes:
ldd wrf.exe => (0x00007ffe75b69000) => /opt/netCDF/lib/ (0x00002aca531a5000) => /opt/netCDF/lib/ (0x00002aca5374b000) => /opt/HDF5/lib/ (0x00002aca56af4000) => /lib64/ (0x00002aca570b5000) => /lib64/ (0x00002aca573b8000) => /opt/intel/impi/2018.1.163/intel64/lib/ (0x00002aca575ce000) => /opt/intel/impi/2018.1.163/intel64/lib/ (0x00002aca57977000) => /lib64/ (0x00002aca585fd000) => /lib64/ (0x00002aca58801000) => /lib64/ (0x00002aca58a09000) => /lib64/ (0x00002aca58c26000) => /lib64/ (0x00002aca58fe9000) => not found

Does anyone has a solution to this problem?
Thanks for your help!
