2.5 Compiling a Program Containing C Preprocessor Directives Using kfort

If your Fortran program contains C preprocessor directives and you do not want to use any additional C preprocessor directives in the kfort command line, use the Fortran compiler qualifiers /cpp , as follows:

kfort /cpp myprog.f

The /cpp qualifier causes the C preprocessor to run on your Fortran program before compilation.

In the event you want to use C preprocessor directives in the kfort command line, you must also include the C preprocessor qualifier /C to avoid errors resulting from C comment lines. For example, in the following kfort command line where /Dfoo is a C preprocessor qualifier, you must include /C , as follows:

kfort /cpp /C /Dfoo myprog.f

The kfort driver does not set the /C qualifier when you use C preprocessor directives in the command line. Without the /C qualifier, an error message results from the following program lines:

    PRINT 5
  5   FORMAT(//,'above are 2 blank lines')
      end
