nc-config utility

----------------------------------------------------------------
 Using the nc-config Utility to Find Compiler and Linker Flags
----------------------------------------------------------------

To assist with the setting of compiler and linker flags, the nc-config utility is provided with netCDF. The nc-config utility is a very simple script which contains the settings of the C and Fortran flags used during the netCDF build.

For example, the nc-config command can be used to get the command line options needed to link a C program to netCDF:

     nc-config --libs
     -L/usr/local/lib -lnetcdf -L/shecky/local_post/lib -lhdf5_hl -lhdf5 -lz

The nc-config utility can also be used to learn about the features of the current netCDF installation. For example, it can show whether netCDF-4 is available:

     ./nc-config --has-nc4
     yes

Use the –help option to nc-config for a full list of available information.

1. Usage of nc-config
----------------------
[dxu@goesrgnrx bin]$  ./nc-config -h
unknown option: -h
Usage: nc-config [OPTION]

Available values for OPTION include:

  --help      display this help message and exit
  --all       display all options
  --cc        C compiler
  --cxx       C++ compiler
  --fc        Fortran compiler
  --cflags    pre-processor and compiler flags
  --fflags    flags needed to compile a Fortran program
  --has-dap   whether OPeNDAP is enabled in this build
  --has-nc2   whether NetCDF-2 API is enabled
  --has-nc4   whether NetCDF-4/HDF-5 is enabled in this build
  --has-hdf5  same as --has-nc4
  --has-f77   whether Fortran 77 API is enabled in this build
  --has-f90   whether Fortran 90 API is enabled in this build
  --has-c++   whether C++ API is enabled in this build
  --libs      library linking information for netcdf
  --flibs     libraries needed to link a Fortran program
  --prefix    Install prefix
  --version   Library version
