An overview of HP Fortran
Chapter 12
intermediate code, optimize the intermediate code, produce object code, search a set of library
files for any additional object code that may be required, and link all of the object code into an
executable file that you run without further processing.
For example, consider a program that consists of three source files: x.f90, y.f90, and z.f90.
The following command line will process the source files and, if they are syntactically correct,
produce an executable file with the default name a.out:
$ f90 x.f90 y.f90 z.f90
After compilation is complete, you can execute the program by invoking the name of the
executable, as follows:
$ a.out
However, it is likely that you’ll want to control what components act on your program and
what they do to it. For example, you may want to give the executable a name other than a.out
or to link in other libraries than the default ones. The HP Fortran compiler supports a variety
of command-line options that enable you to control the compilation process. This chapter
provides an overview of the process and of the options that enable you to control the different
components invoked by the f90 command.
NOTE To get a summary listing of all f90 options, refer to the f90(1) man page or use
the command, as shown here:
$ f90 +usage
For a full description of the options, refer to the most current version of the
Parallel Programming Guide for HP-UX Systems.
