Driver
Chapter 14
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 1-1 lists and briefly describes the options that control the driver.

Option Function
-c Suppress the link phase and produce an object file (.o) from each
source file on the command line.
-o outfile 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.
