CC(1) UNIX Programmer's Manual CC(1)

== NAME ==
cc - C compiler

== SYNOPSIS ==
cc [ option ] ... file ...

== DESCRIPTION ==
_C_c is the UNIX C compiler. It accepts several types of
arguments:

Arguments whose names end with `.c' are taken to be C source
programs; they are compiled, and each object program is left
on the file whose name is that of the source with `.o' sub-
stituted for `.c'. The `.o' file is normally deleted, how-
ever, if a single C program is compiled and loaded all at
one go.

In the same way, arguments whose names end with `.s' are
taken to be assembly source programs and are assembled, pro-
ducing a `.o' file.

The following options are interpreted by _c_c. See _l_d(1) for
load-time options.

-c Suppress the loading phase of the compilation, and
force an object file to be produced even if only one
program is compiled.

-p Arrange for the compiler to produce code which
counts the number of times each routine is called;
also, if loading takes place, replace the standard
startup routine by one which automatically calls
_m_o_n_i_t_o_r(3) at the start and arranges to write out a
_m_o_n._o_u_t file at normal termination of execution of
the object program. An execution profile can then
be generated by use of _p_r_o_f(1).

-O Invoke an object-code improver.

-S Compile the named C programs, and leave the
assembler-language output on corresponding files
suffixed `.s'.

-E Run only the macro preprocessor on the named C pro-
grams, and send the result to the standard output.

-o _o_u_t_p_u_t
Name the final output file _o_u_t_p_u_t. If this option
is used the file `a.out' will be left undisturbed.

-D_n_a_m_e=_d_e_f
-D_n_a_m_e Define the _n_a_m_e to the preprocessor, as if by
`#define'. If no definition is given, the name is
defined as "1".

-U_n_a_m_e Remove any initial definition of _n_a_m_e.

-I_d_i_r `#include' files whose names do not begin with `/'
are always sought first in the directory of the _f_i_l_e
argument, then in directories named in -I options,
then in directories on a standard list.

-B_s_t_r_i_n_g
Find substitute compiler passes in the files named
_s_t_r_i_n_g with the suffixes cpp, ccom, and c2. If
_s_t_r_i_n_g is empty, use a standard backup version.

-t[p012]
Find only the designated compiler passes in the
files whose names are constructed by a -B option.
In the absence of a -B option, the _s_t_r_i_n_g is taken
to be `/usr/c/'.

Other arguments are taken to be either loader option argu-
ments, or C-compatible object programs, typically produced
by an earlier _c_c run, or perhaps libraries of C-compatible
routines. These programs, together with the results of any
compilations specified, are loaded (in the order given) to
produce an executable program with name a.out.

== DIAGNOSTICS ==
The diagnostics produced by C itself are intended to be
self-explanatory. Occasional messages may be produced by
the assembler or loader.
