Compiler options remain in effect for the whole compilation unless overridden by a
compiler directive.
Certain options accept one or more keyword arguments following the option name
on Windows*. To specify multiple keywords, you typically specify the option multiple
times. However, some options allow comma-separated keywords. For example:
• Options that use a colon can use an equal sign (=) instead.
• Standard output and standard error can be redirected to a file, avoiding
displaying excess text, which slows down execution; scrolling text in a terminal
window on a workstation can cause an I/O bottleneck (increased elapsed time)
and use more CPU time. See the examples in the next section.
Configuration Description
Debug configuration By default, the debug configuration sets project options to
include the debugging information in the debug configuration. It
also turns off optimizations. Before you can debug an
application, you must build a debug configuration for the project.
Release (Retail) configuration The release configuration does not include the debugging
information, and it uses any optimizations that you have chosen.
Multithreaded Programs
If the program is multithreaded, each thread starts on whichever processor is available at the time. On a
computer with one processor, the threads all run in parallel, but not simultaneously; the single processor
switches among them. On a computer with multiple processors, the threads can run simultaneously.
Using the -fpscomp filesfromcmd Option
If you specify the fpscomp option with keyword filesfromcmd, the command line that executes the
program can include additional filenames to satisfy OPEN statements in the program for which the filename
field (FILE specifier) has been left blank. The first filename on the command line is used for the first OPEN
statement executed, the second filename for the second OPEN statement, and so on.
The driver program
does the following:
• Calls the Intel® Fortran Compiler to process Fortran files.
• Passes the linker options to the linker.
• Passes object files created by the compiler to the linker.
• Passes libraries to the linker.
• Calls the linker or librarian to create the executable or library file.
Because the driver calls other software components, they may return error messages. For instance, the
linker may return a message if it cannot resolve a global reference. The watch option can help clarify which
component is generating an error.
