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.
