NAME

       nhlcc - Command for compiling C code that uses the NCAR Graphics high-level utilities.

SYNOPSIS

       nhlcc [-ngmath] [-ncarbd] [-ngmathbd] [-netcdf] [-hdf] ...

DESCRIPTION

       nhlcc  is  a  script  that invokes the C compiler/linker with the proper NCAR Graphics LLU
       (low-level utility) and HLU (high-level utility) libraries.  Arguments presented above are
       associated  with  NCAR  Graphics.  All other arguments and options are identical to the cc
       command on your particular machine; arguments that include quoted strings may have  to  be
       enclosed in single quotes.

       If  you don't want to use nhlcc, you can just type it on the command line to see what gets
       included in the link line, and then you can add this information to your own  Makefile  or
       script.  It is important to note that you must define the macro NeedFuncProto in order for
       function prototyping to work correctly.

       In order to run nhlcc, you must have your  NCARG_ROOT  environment  variable  set  to  the
       directory  pathname  where  the  NCAR Graphics libraries, binaries, and include files were
       installed.  If you are not sure what NCARG_ROOT should be set to, please check  with  your
       system  administrator  or the site representative for NCAR Graphics.  If the NCAR Graphics
       libraries, binaries, and include files were not installed under one root  directory,  then
       you  will  need  to  set the environment variables NCARG_LIB, NCARG_BIN, and NCARG_INCLUDE
       instead.  Please see "man ncargintro" for more information.

       Note that, on some systems, if you supply your own binary libraries  in  addition  to  the
       ones  automatically  referenced  by  nhlcc,  all the libraries must have been created in a
       similar fashion.

       OPTIONS

       -ngmath
              Links in the NCAR Graphics ngmath library.

       -ncarbd
              Use this option for  compilers  that  appear  to  be  having  trouble  initializing
              blockdata  variables.  It  will cause a small subroutine to be linked in that helps
              force the loading of blockdata initialization routines.

       -ngmathbd
              Just like with the -ncarbd option, use this option for compilers that appear to  be
              having  trouble  initializing  Ngmath-related  blockdata variables. It will cause a
              small subroutine to be linked in that helps force the loading of  Ngmath  blockdata
              initialization routines.

              Note:  this  option  doesn't  need  to  be  specified separately if you are already
              including the -ncarbd  and -ngmath options.

       -netcdf
              Links in the netCDF library.  This library is not part of NCAR Graphics,  so  check
              with  your system administrator if you need it installed.  You can obtain a copy of
              it by doing an anonymous ftp to unidata.ucar.edu.

       -hdf   Links in the HDF library.  This library is not part of NCAR Graphics, so check with
              your system administrator if you need it installed.  You can obtain a copy of it by
              doing an anonymous ftp to ftp.ncsa.uiuc.edu.
