CHAPTER 2
cc: C COMPILER
This chapter explains how to use the cc command. In particular, it explains how to
• Compile C language source files
• Choose a memory model for a program
• Use object files and libraries with a program
• Create smaller and faster programs
• Prepare C programs for debugging
• Control the C preprocessor
It also describes the error and warning messages generated by the C compiler and
explains how to use advanced features of the cc command to make customized
programs.
This chapter assumes that you are familiar with the C programming language and that
you can create C program source files using a XENIX text editor.
Invoking the C Compiler
The cc command has the form
cc [ option ] . . . filename ...
where option is a command option, and filename is the name of a C language source file,
an assembly language source file, an object file, or an archive library. You may give
more than one option or file name, if desired, but you must separate each item with one
or more spaces.
The cc command options control and modify the tasks performed by the command. For
example, you can direct cc to perform optimization or create an assembly listing file.
The options also specify additional information about the compilation, such as which
program libraries to examine and what the name of the executable file should be. Many
options are described in the following sections. For a complete description of all
options, see the entry cc in Appendix B, "Programming Commands."
