33 .Nd POSIX.2 C language compiler
37 .Op Fl D Ar name Ns Op = Ns Ar value
41 .Op Fl I Ar directory ...
42 .Op Fl L Ar directory ...
49 This is the name of the C language compiler as required by the
55 compiler accepts the following options:
56 .Bl -tag -width indent
58 Suppress the link-edit phase of the compilation, and do not remove any
59 object files that are produced.
60 .It Fl D Ar name Ns Op = Ns Ar value
61 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.
76 option has lower precedence than the
87 will be undefined regardless of the order of the options.
90 option may be specified more than once.
92 Copy C-language source files to the standard output, expanding all
93 preprocessor directives; no compilation will be performed.
95 Produce symbolic information in the object or executable files.
97 Change the algorithm for searching for headers whose names are not
98 absolute pathnames to look in the directory named by the
100 pathname before looking in the usual places.
102 names are enclosed in double-quotes ("") will be searched for first
103 in the directory of the file with the
108 options, and last in the usual places.
110 headers whose names are enclosed in angle brackets (<>), the header
111 will be searched for only in directories named in
113 options and then in the usual places.
116 options shall be searched in the order specified.
119 option may be specified more than once.
120 .It Fl L Ar directory
121 Change the algorithm of searching for the libraries named in the
123 objects to look in the directory named by the
125 pathname before looking in the usual places.
128 options will be searched in the order specified.
131 option may be specified more than once.
135 instead of the default
137 for the executable file produced.
139 Optimize the compilation.
141 Produce object and/or executable files from which symbolic and other
142 information not required for proper execution has been removed
145 Remove any initial definition of

152 An operand is either in the form of a pathname or the form
155 At least one operand of the pathname form needs to be
157 Supported operands are of the form:
158 .Bl -tag -offset indent -width "-l library"
160 A C-language source file to be compiled and optionally linked.
162 operand must be of this form if the
166 A library of object files, as produced by
168 passed directly to the link editor.
170 An object file produced by
172 and passed directly to the link editor.
174 Search the library named
175 .Pa lib Ns Ar library Ns Pa .a .
176 A library will be searched when its name is encountered, so the
179 operand is significant.
