PROGRAM:

NAME

ncargf77 - Command for compiling Fortran code that uses the NCAR Graphics low-level
utilities

SYNOPSIS

ncargf77 [-ngmath] [-smooth] [-quick] [-super] [-agupwrtx] [-ncarbd] [-ngmathbd]
[-ictrans] [-noX11] ...

DESCRIPTION

ncargf77 is a script that invokes the FORTRAN 77 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 f77 command on your
particular machine; arguments that include quoted strings may have to be enclosed in
single quotes.

NOTE: ncargf77 cannot be used to compile NCAR Graphics Fortran programs that call the HLUs
(high-level utilities). You must use nhlf77 instead. See the nhlf77 man page for more
information.

In order to run ncargf77, 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 ncargf77, all the libraries must have been created in a
similar fashion.

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.

-ictrans
When ncargf77 is invoked with the this 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.

-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.
