Fortran Library Reference HomeContentsPreviousNextIndex


The Fortran Library Reference describes the routines in the Sun WorkShopTM Fortran libraries. This reference manual is intended for programmers with a working knowledge of the Fortran language and the SolarisTM operating environment.

Multiplatform Release

This Sun WorkShop Fortran release supports versions 2.6, 7, and 8 of the SolarisTM SPARCTM Platform Edition Operating Environment.

See the fortran_77 and fortran_95 README files in the Sun WorkShop READMEs directory for release information regarding availability of the Fortran compilers and libraries on specific platforms.

Access to Sun WorkShop Development Tools

Because Sun WorkShop product components and man pages do not install into the standard /usr/bin/ and /usr/share/man directories, you must change your PATH and MANPATH environment variables to enable access to Sun WorkShop compilers and tools.

To determine if you need to set your PATH environment variable:

1. Display the current value of the PATH variable by typing:

% echo $PATH

2. Review the output for a string of paths containing /opt/SUNWspro/bin/.

If you find the paths, your PATH variable is already set to access Sun WorkShop development tools. If you do not find the paths, set your PATH environment variable by following the instructions in this section.

To determine if you need to set your MANPATH environment variable:

1. Request the workshop man page by typing:

% man workshop

2. Review the output, if any.

If the workshop(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 this section for setting your MANPATH environment variable.

Note – The information in this section assumes that your Sun WorkShop 6 products were installed in the /opt directory. Contact your system administrator if your Sun WorkShop software is not installed in /opt.

The PATH and MANPATH variables should be set in your home .cshrc file if you are using the C shell or in your home .profile file if you are using the Bourne or Korn shells:

For more information about the PATH variable, see the csh(1), sh(1), and ksh(1) man pages. For more information about the MANPATH variable, see the man(1) man page. For more information about setting your PATH and MANPATH variables to access this release, see the Sun WorkShop 6 Installation Guide or your system administrator.
