Greetings Irena! The error says that several symbols are not found being in ./fortran/.libs/libnetcdff.so, so let's check if there are any symbols that resemble what cannot be found. Please go to the directory that contains libnetcdff.so (<netCDf build dir>/fortran/.libs) and execute the following command: readelf -Ws /usr/lib64/libnetcdff.so.5.0.0 | grep nf_open The output will look something like this: 437: 0000000000016ea0 284 FUNC GLOBAL DEFAULT 11 nf_open_par_ 485: 000000000000ed80 240 FUNC GLOBAL DEFAULT 11 nf_open_ Would you please send me the output for your copy of libnetcdff.so? Thanks!
