Compiling and Executing Stand-alone FORTRAN Programs

Basic compilation and execution

   f77 [input filename]   -o [output filename]

• the <input filename> contains the FORTRAN source program. The filename should have a ".f" suffix (e.g., myprog.f).

• the <output filename> receives the compiled, executable code. e> Note:
  MUST NOT HAVE a ".o" suffix .

  For example, to compile the FORTRAN program in "myprog.f" and create the executable file "myprog.exe", type

     f77 myprog.f  -o myprog.exe

  If you do not include the output filename option "-o", as in

     f77 myprog.f

  the output filename is automatically named "a.out".

  To execute the program, type the name of the output file. For example, type

     myprog.exe

  or

     a.out

  See the tip sheet "Fortran Compiler Options" for further discussion of the compiler options on the f77 command.

  For information about compiling and executing programs that call subprograms that are stored in a separate file, see the tip sheet, "Compiling and Executing Programs Using External Subprograms".

  On-line UNIX man page

  Type

     man f77

  Essential PATH and MANPATH variable settings

  --------------------------------------------

  The following paths must be included in the PATH and MANPATH environment variables for the f77 and man commands to work properly:

  
       In PATH:       /opt/SUNWspro/bin       
  
       In MANPATH:    /opt/SUNWspro/man
  
  

  These variables are automatically set to the values shown above by the start-up files, also known as "dotfiles" (.cshrc, .login, .localenv, .localalias). If they are not, then you are not using the most current versions of these files. To make an automatic backup of your current "dotfiles" and replace them with the current versions, type the following command at the UNIX prompt:

     ~consult/proto/xsetup

  If you have defined your own aliases or environment variables, you will need to copy them into the new "dotfiles". Instructions are available on U-Discover!.
