HP UX Fortran Software Driver, Options for controlling the f90 driver, +dryrun, +preinclude= file

Figure 1 HP Fortran compiler environment

Driver

The driver parses the f90 command line by which you invoke the compiler, calls each subprocess as needed to complete the compilation, and retains control throughout the compilation process.

Command-line options that control driver functions enable you to do the following:

•Call subprocesses that you want to substitute for those that f90 calls by default

•Pass arguments to a subprocess

•Get a summary listing of all options supported by the compiler

•Display information about the version of f90 you are using

•Control the level of information that the driver displays about the compilation process Table 1 (page 9) lists and briefly describes the options that control the driver

Table 1 Options for controlling the f90 driver

Option	Function
-c	Suppress the link phase and produce an object file (.o)
	from each source file on the command line.
+dryrun	Generate sub-process information for a given f90
	command-line without running the sub-processes.
-o	Name the output file outfile instead of the default file
	name (a.out or filename.o). If linking has been
	suppressed, the front end uses this option to name the
	object file.
+pre_include=file	Process contents of file before all source files specified
	on the command line. The command line can have multiple
	occurrences of this option, each specifying a different
	file; they are processed in the specified order.
-tx,name	Substitute a private version (name) of one or more
	subprocesses (x) of the compilation. The values for x are:
	a	Assembler
	c	Compiler
	l	Linker
	p	C preprocessor
	s	Startup file (crt0.o library)
	e	Debug file (end.o library)
