Hi Prabhakar, The message output from "make check" is saying it can't find the library libintlc that's supposed to be installed as runtime support for the Intel C compiler: /store/home/prabhakar/netcdf-3.6.2/netcdf-3.6.2/nf_test/.libs/lt-nf_test: error while loading shared libraries: libintlc.so.6: cannot open shared object file: No such file or directory FAIL: nf_test I have not seen this problem before, but it may be a problem with the icc installation. Are you able to compile and run a simple C program with icc? If you use the "ldd" command on that executable program, does it show a reference to the shared library libintlc.so.6? --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: CKR-624572 Department: Support netCDF Priority: Normal Status: Closed
