Chapter 2: Compiling Your Application

This chapter provides information for compiling your application with either archived or shared libraries for the following Application Programming Interfaces (APIs): Starbase, HP-PHIGS, and HP PEX. Compiling examples are given for C, Fortran, and Pascal.

The actual pathnames of the conceptual (<italicized and angle-bracketed>) directory names in this chapter depends on the file system structure. See Chapter 1 for details.

Compiling Starbase Applications

Compiling with Shared Libraries

The compiler programs (cc, f77, and pc) link with Starbase shared libraries by default. Starbase will explicitly load the appropriate device driver library at run time when you compile and link with the shared library <common> /lib/libhpgfx.sl, or use the -lhpgfxoption. This loading occurs at gopen(3G) time.

Examples

Assuming you are using ksh(1), to compile and link a C program for use with the shared library driver, use the forms below.

ccexample.c –I<sb-incl> -L<common> -L<sb-lib> -lXwindow \ -lhpgfx -lXhp11 -lX11 -lm -ldld -o example

For FORTRAN:

fort77 example.f –I<sb-incl> -L<common> -L<sb-lib> -lXwindow \ -lhpgfx -lXhp11 -lX11 -lm -ldld -o example

For Pascal:

pc example.p –I<sb-incl> -Wl,-L<common> -Wl,-L<sb-lib> \ -lXwindow -lhpgfx -lXhp11 -lX11 -lm - ldld -o example

Compiling with Archive Libraries

You can link the appropriate library, for your specific device driver, to a program by using any one of the following:

•The path name <sb-lib>/<library_name>.a;

•An appropriate relative path name; or

•The –ldd<device_driver>option (for example, -lddhcrx) with the LDOPTS environment variable set to -a archive and exported. Or (preferred because of fewer side-effects), "-Wl,- a,archive".
