34 .Nd POSIX.2 C language compiler
38 .Op Fl D Ar name Ns Op = Ns Ar value
42 .Op Fl I Ar directory ...
43 .Op Fl L Ar directory ...
50 This is the name of the C language compiler as required by the
56 compiler accepts the following options:
57 .Bl -tag -width indent
59 Suppress the link-edit phase of the compilation, and do not remove any
60 object files that are produced.
61 .It Fl D Ar name Ns Op = Ns Ar value
62 Define name as if by a C-language
67 is given, a value of 1 will be used.
68 Note that in order to request a
69 translation as specified by
73 either in the source or using this option. The
75 option has lower precedence than the
85 will be undefined regardless of the order of the options. The
87 option may be specified more than once.
89 Copy C-language source files to the standard output, expanding all
90 preprocessor directives; no compilation will be performed.
92 Produce symbolic information in the object or executable files.
94 Change the algorithm for searching for headers whose names are not
95 absolute pathnames to look in the directory named by the
97 pathname before looking in the usual places. Thus, headers whose
98 names are enclosed in double-quotes ("") will be searched for first
99 in the directory of the file with the
104 options, and last in the usual places. For
105 headers whose names are enclosed in angle brackets (<>), the header
106 will be searched for only in directories named in
108 options and then in the usual places. Directories named in
110 options shall be searched in the order specified. The
112 option may be specified more than once.
113 .It Fl L Ar directory
114 Change the algorithm of searching for the libraries named in the
116 objects to look in the directory named by the
118 pathname before looking in the usual places. Directories named in
120 options will be searched in the order specified. The
122 option may be specified more than once.
126 instead of the default
128 for the executable file produced.
130 Optimize the compilation.
132 Produce object and/or executable files from which symbolic and other
133 information not required for proper execution has been removed
136 Remove any initial definition of
140 option may be specified more than once.
143 An operand is either in the form of a pathname or the form
145 library. At least one operand of the pathname form needs to be
146 specified. Supported operands are of the form:
147 .Bl -tag -offset indent -width "-l library"
149 A C-language source file to be compiled and optionally linked. The
150 operand must be of this form if the
154 A library of object files, as produced by
156 passed directly to the link editor.
158 An object file produced by
160 and passed directly to the link editor.
162 Search the library named
163 .Pa lib Ns Ar library Ns Pa .a .
164 A library will be searched when its name is encountered, so the
167 operand is significant.
