.Sh DESCRIPTION
|
|
This is the name of the C language compiler as required by the
|
|
.St -p1003.2
|
|
standard.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
compiler accepts the following options:
|
|
.Bl -tag -width indent
|
|
.It Fl c
|
|
Suppress the link-edit phase of the compilation, and do not remove any
|
|
object files that are produced.
|
|
.It Fl D Ar name Ns Op Ar =value
|
|
Define name as if by a C-language
|
|
.Ql #define
|
|
directive. If
|
|
no
|
|
.Ar =value
|
|
is given, a value of 1 will be used. The
|
|
.Fl D
|
|
option has lower precedence than the
|
|
.Fl U
|
|
option. That is, if
|
|
.Ar name
|
|
is used in both a
|
|
.Fl U
|
|
and a
|
|
.Fl D
|
|
option,
|
|
.Ar name
|
|
will be undefined regardless of the order of the options. The
|
|
.Fl D
|
|
option may be specified more than once.
|
|
.It Fl E
|
|
Copy C-language source files to the standard output, expanding all
|
|
preprocessor directives; no compilation will be performed.
|
|
.It Fl g
|
|
Produce symbolic information in the object or executable files.
|
|
.It Fl I Ar directory
|
|
Change the algorithm for searching for headers whose names are not
|
|
absolute pathnames to look in the directory named by the
|
|
.Ar directory
|
|
pathname before looking in the usual places. Thus, headers whose
|
|
names are enclosed in double-quotes (\&"\&") will be searched for first
|
|
in the directory of the file with the
|
|
.Ql #include
|
|
line, then in
|
|
directories named in
|
|
.Fl I
|
|
options, and last in the usual places. For
|
|
headers whose names are enclosed in angle brackets (<>), the header
|
|
will be searched for only in directories named in
|
|
.Fl I
|
|
options and then in the usual places. Directories named in
|
|
.Fl I
|
|
options shall be searched in the order specified. The
|
|
.Fl I
|
|
option may be specified more than once.
|
|
.It Fl L Ar directory
|
|
Change the algorithm of searching for the libraries named in the
|
|
.Fl l
|
|
objects to look in the directory named by the
|
|
.Ar directory
|
|
pathname before looking in the usual places. Directories named in
|
|
.Fl L
|
|
options will be searched in the order specified. The
|
|
.Fl L
|
|
option may be specified more than once.
|
|
.It Fl o Ar outfile
|
|
Use the pathname
|
|
.Ar outfile ,
|
|
instead of the default
|
|
.Pa a.out ,
|
|
for the executable file produced.
|
|
.It Fl O
|
|
Optimize the compilation.
|
|
.It Fl s
|
|
Produce object and/or executable files from which symbolic and other
|
|
information not required for proper execution has been removed
|
|
(stripped).
|
|
.It Fl U Ar name
|
|
Remove any initial definition of
|
|
.Ar name .
|
|
The
|
|
.Fl U
|
|
option may be specified more than once.
|
|
.El
|
|
.Pp
|
|
An operand is either in the form of a pathname or the form
|
|
.Fl l
|
|
library. At least one operand of the pathname form needs to be
|
|
specified. Supported operands are of the form:
|
|
.Bl -tag -offset indent -width "-l library"
|
|
.It Pa file Ns \&.c
|
|
A C-language source file to be compiled and optionally linked. The
|
|
operand must be of this form if the
|
|
.Fl c
|
|
option is used.
|
|
.It Pa file Ns \&.a
|
|
A library of object files, as produced by
|
|
.Xr ar 1 ,
|
|
passed directly to the link editor.
|
|
.It Pa file Ns \&.o
|
|
An object file produced by
|
|
.Nm
|
|
.Fl c ,
|
|
and passed directly to the link editor.
|
|
.It Fl l Pa library
|
|
Search the library named
|
|
.Dl lib Ns Em library Ns \&.a
|
|
A library will be searched when its name is encountered, so the
|
|
placement of a
|
|
.Fl l
|
|
operand is significant.
