This note explains how the C binding to PGPLOT (cpgplot) can be used
under Windows. It applies to
* C programs compiled with MS Visual C++ V4.0;
* calling PGPLOT compiled with MS Powerstation Fortran V4.0;
* under MS Windows-95 or Windows-NT.
Other compilers may use different calling conventions and will require
a different version of the C binding.
You need the following files from PGPLOT v5.2 or later:
pgplot/cpg/pgbind.c
pgplot/cpg/pgbind_prototypes
pgplot/sys_win/pgbind.mak
(pgbind_prototypes is a list of the C function prototype lines
extracted from the Fortran source code for PGPLOT.)
-----------------------------------------------------------------------
Installation:
To build the cpgplot binding library, you will need the following
files:
pgbind.c
pgbind.mak
pgbind_prototypes
These files can be located anywhere convenient.
To build the library, from a console (DOS) window type
NMAKE /F PGBIND.MAK
This will create cpgplot.lib and cpgplot.h
The makefile compiles pgbind.c (no unusual compiler flags are needed)
to produce the pgbind program. It then produces the C wrapper functions
(one file per wrapper) and the cpgplot.h header file using:
pgbind ms -w -h pgbind_prototypes
The cpg*.c files are then compiled and gathered into a library.
-------------------------------------------------------------------------
Usage:
To use cpgplot in your programs, you should include cpgplot.h
at the top of all C files that use cpgplot functions, and link your
programs with both of cpgplot.lib and pgplot.lib.
For further information about using the C binding, see file
pgplot/cpg/cpgplot.doc
