Assignment

Create a makefile for the following project which consists of 3 Fortran files and one routine written in C. The makefile should allow 3 different options:

Command	Action
make	Make the default executable from the files main.f, timewrap.f, and dateclock.c.
make simple	Make a different executable from the files main.f, and dum.f.
make clean	Delete all object files created.

Files:

• main.f
• timewrap.f
• dum.f
• dateclock.c

Details

• The *.f files can be compiled with the default f77 compiler
• dateclock.c can be compiled with the default cc compiler
• The f77 program can be used to link your code.
• Try to arrange your Makefile to minimize rebuilds.
• You do NOT need to edit any of the source code

Tips

• You will need to define how to compile the individual files, either explicitly or by defining rules.
• You will need to define each of the three procedures your makefile will do.

A solution

Note: You will need to change spaces into tabs if you cut and paste this.
