Howdy DEVARAJU!

Are you trying to cross-compile netCDF? That is, is the platform you are 
running on different from the target platform?

If you cannot run programs on the platform, but can compile for it, you can run 
configure with --disable-fortran-type-check, but then you should look in the 
configure file and make sure the defaults will work on your fortran compiler:
      $as_echo "#define NCBYTE_T byte" >>confdefs.h
      $as_echo "#define NCSHORT_T integer*2" >>confdefs.h
      $as_echo "#define NF_INT1_T byte" >>confdefs.h
      $as_echo "#define NF_INT2_T integer*2" >>confdefs.h
$as_echo "#define NF_INT1_IS_C_SIGNED_CHAR 1" >>confdefs.h
$as_echo "#define NF_INT2_IS_C_SHORT 1" >>confdefs.h
$as_echo "#define NF_INT_IS_C_INT 1" >>confdefs.h
$as_echo "#define NF_REAL_IS_C_FLOAT 1" >>confdefs.h
$as_echo "#define NF_DOUBLEPRECISION_IS_C_DOUBLE 1" >>confdefs.h

Thanks,

Ed
