PROGRAM:

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.
