Before You Begin |
The Fortran Library Reference describes the intrinsic functions and routines in the Sun Studio Fortran libraries. This reference manual is intended for programmers with a working knowledge of the Fortran language and the Solaris operating environment.
This guide is intended for scientists, engineers, and programmers who have a working knowledge of the Fortran language and wish to learn how to use the Sun Fortran compilers effectively. Familiarity with the Solaris operating environment or UNIX® in general is also assumed.
Discussion of Fortran programming issues on Solaris operating environments, including input/output, application development, library creation and use, program analysis, porting, optimization, and parallelization can be found in the companion Fortran Programming Guide.
The "pipe" or "bar" symbol separates arguments, only one of which may be chosen. |

The colon, like the comma, is sometimes used to separate arguments. |

This Sun Studio release supports systems that use the SPARC® and x86 families of processor architectures: UltraSPARC®, SPARC64, AMD64, Pentium, and Xeon EM64T. The supported systems for the version of the Solaris Operating System you are running are available in the hardware compatibility lists at http://www.sun.com/bigadmin/hcl. These documents cite any implementation differences between the platform types.
In this document, the term "x86" refers to 64-bit and 32-bit systems manufactured using processors compatible with the AMD64 or Intel Xeon/Pentium product families. For supported systems, see the hardware compatibility lists.
The Sun Studio software and its man pages are not installed into the standard /usr/bin/ and /usr/share/man directories. To access the software, you must have your PATH environment variable set correctly (see Accessing the Compilers and Tools). To access the man pages, you must have the your MANPATH environment variable set correctly (see Accessing the Man Pages.).
For more information about the PATH variable, see the csh(1), sh(1), ksh(1), and bash(1) man pages. For more information about the MANPATH variable, see the man(1) man page. For more information about setting your PATH variable and MANPATH variables to access this release, see the installation guide or your system administrator.
Use the steps below to determine whether you need to change your PATH variable to access the compilers and tools.
To Determine Whether You Need to Set Your PATH Environment Variable |
1. Display the current value of the PATH variable by typing the following at a command prompt.
2. Review the output to find a string of paths that contain /opt/SUNWspro/bin/.
If you find the path, your PATH variable is already set to access the compilers and tools. If you do not find the path, set your PATH environment variable by following the instructions in the next procedure.
To Set Your PATH Environment Variable to Enable Access to the Compilers and Tools |
1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.
2. Add the following to your PATH environment variable. If you have Forte Developer software, Sun ONE Studio software or another release of Sun Studio software installed, add the following path before the paths to those installations.
Use the following steps to determine whether you need to change your MANPATH variable to access the man pages.
To Determine Whether You Need to Set Your MANPATH Environment Variable |
1. Request the dbx man page by typing the following at a command prompt.
If the dbx(1) man page cannot be found or if the man page displayed is not for the current version of the software installed, follow the instructions in the next procedure for setting your MANPATH environment variable.
To Set Your MANPATH Environment Variable to Enable Access to the Man Pages |
1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.
2. Add the following to your MANPATH environment variable.
The Sun Studio integrated development environment (IDE) provides modules for creating, editing, building, debugging, and analyzing the performance of a C, C++, or Fortran application.
The command to start the IDE is sunstudio. For details on this command, see the sunstudio(1) man page.
The correct operation of the IDE depends on the IDE being able to find the core platform. The sunstudio command looks for the core platform in two locations:
If the core platform is not installed or mounted to either of the locations where the sunstudio command looks for it, then each user on a client system must set the environment variable SPRO_NETBEANS_HOME to the location where the core platform is installed or mounted (/installation_directory/netbeans/3.5V).
Each user of the IDE also must add /installation_directory/SUNWspro/bin to their $PATH in front of the path to any other release of Forte Developer software, Sun ONE Studio software, or Sun Studio software.
The path /installation_directory/netbeans/3.5V/bin should not be added to the user's $PATH.
You can access the documentation at the following locations:
If your software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.
The docs.sun.com web site (http://docs.sun.com) enables you to read, print, and buy Sun Microsystems manuals through the Internet. If you cannot find a manual, see the documentation index that is installed with the software on your local system or network.
The documentation is provided in accessible formats that are readable by assistive technologies for users with disabilities. You can find accessible versions of documentation as described in the following table. If your software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.
