make

You should create a Makefile and use make to compile your code. information about how make works can be obtained from a number of sources, including:

• A locally developed tutorial by David Jones.
• Ben Y. Yoshino of the University of Hawai`i, College of Engineering, Computer Facility also wrote a very nice tutorial.
• Then, of course, there is always the man page (type man make at the UNIX prompt).
• Finally, you can find out about all of the gory details if you want on these info pages.

To help you out, there is a sample Makefile you can copy and modify. The Makefile includes the following lines:

• • CC=         gcc
    CFLAGS=     -g -ansi -Wall
    LDFLAGS=    -g
    LINKER=     gcc

•  The CC line indicates that the Gnu C compiler, called gcc, should be used. If you instead would want to use Sun's C compiler, which is called cc, then you would have to change gcc to cc.

• The CFLAGS line has three flags that are passed to the compiler:
  • -g indicates that debugging information should be included with the compiled code so that you can use the debugger with it.
  • -ansi indicates that all ANSI C-compatible programs compile properly
  • -Wall indicates that you want to see all warning messages.

• The LDFLAGS line indicates to the linker that debugging information should be included.

• The LINKER line indicates that gcc should be used to link together the program.

If you intend to use cc as the compiler, then you must change the above Makefile lines to:

• CC=         cc
  CFLAGS=     -g
  LDFLAGS=    -g
  LINKER=     cc
