PROGRAM:
NAME
ncargcc - Command for compiling C code that uses the NCAR Graphics low-level utilities
SYNOPSIS
ncargcc [-ngmath] [-smooth] [-quick] [-super] [-agupwrtx] [-ncarbd] ... [-ngmathbd] ...
[-noX11] ...
DESCRIPTION
ncargcc is a script that invokes the C compiler/linker with the proper NCAR Graphics LLU
(low-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.
NOTE: ncargcc cannot be used to compile NCAR Graphics C programs that call the HLUs (high-
level utilities). You must use nhlcc instead. See the nhlcc man page for more
information.
If you don't want to use ncargcc, 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 ncargcc, 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.
When ncargcc is invoked with the -ictrans option the resulting executable will, upon
invocation, send its metafile output to the translator ictrans. The environment variable
GRAPHCAP must be set to a valid graphics output device whenever the executable is
executed.
By default, ncargcc will load the X11 library when linking your C program. If you try
running ncargcc and the compiler complains that it cannot find the library for X11, then
try running ncargcc -L/xxx/yyy/zzz program.c where /xxx/yyy/zzz is the path leading to
your X11 library. If you do not have the X11 library, or else you just don't want to link
it in, you can use the -noX11 option.
OPTIONS
-ngmath
Links in the NCAR Graphics ngmath library.
-smooth
Link in the "smooth" objects.
-quick Link in the "quick" objects.
-super Link in the "super" objects.
-agupwrtx
Link in the "agupwrtx" 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.
-noX11 Do not link in the X library when linking the code.
By default, ncargf77 will load the X11 library when linking your Fortran program.
This is because the GKS library now has an X11 driver. If you try running ncargf77
and the compiler complains that it cannot find the library for X11, then try
running ncargf77 -L/xxx/yyy/zzz program.f where /xxx/yyy/zzz is the path leading to
your X11 library. If you do not have the X11 library, or else you just don't want
it to be loaded, you can use the -noX11 option.
