If 62no 63.Dq = Ns Ar value 64is given, a value of 1 will be used. 65Note that in order to request a 66translation as specified by 67.St -p1003.1-2001 68you need to define 69.Dv _POSIX_C_SOURCE=200112L 70either in the source or using this option. The 71.Fl D 72option has lower precedence than the 73.Fl U 74option. That is, if 75.Ar name 76is used in both a 77.Fl U 78and a 79.Fl D 80option, 81.Ar name 82will be undefined regardless of the order of the options. The 83.Fl D 84option may be specified more than once. 85.It Fl E 86Copy C-language source files to the standard output, expanding all 87preprocessor directives; no compilation will be performed. 88.It Fl g 89Produce symbolic information in the object or executable files. 90.It Fl I Ar directory 91Change the algorithm for searching for headers whose names are not 92absolute pathnames to look in the directory named by the 93.Ar directory 94pathname before looking in the usual places. Thus, headers whose 95names are enclosed in double-quotes ("") will be searched for first 96in the directory of the file with the 97.Ic #include 98line, then in 99directories named in 100.Fl I 101options, and last in the usual places. For 102headers whose names are enclosed in angle brackets (<>), the header 103will be searched for only in directories named in 104.Fl I 105options and then in the usual places. Directories named in 106.Fl I 107options shall be searched in the order specified. The 108.Fl I 109option may be specified more than once. 110.It Fl L Ar directory 111Change the algorithm of searching for the libraries named in the 112.Fl l 113objects to look in the directory named by the 114.Ar directory 115pathname before looking in the usual places. Directories named in 116.Fl L 117options will be searched in the order specified. The 118.Fl L 119option may be specified more than once. 120.It Fl o Ar outfile 121Use the pathname 122.Ar outfile , 123instead of the default 124.Pa a.out , 125for the executable file produced. 126.It Fl O Ar optlevel 127If 128.Ar optlevel 129is zero, disable all optimizations. Otherwise, enable optimizations at 130the specified level. 131.It Fl s 132Produce object and/or executable files from which symbolic and other 133information not required for proper execution has been removed 134(stripped). 135.It Fl U Ar name 136Remove any initial definition of 137.Ar name . 138The 139.Fl U 140option may be specified more than once. 141.El 142.Pp 143An operand is either in the form of a pathname or the form 144.Fl l 145library. At least one operand of the pathname form needs to be 146specified. Supported operands are of the form: 147.Bl -tag -offset indent -width "-l library" 148.It Ar file Ns Pa .c 149A C-language source file to be compiled and optionally linked. The 150operand must be of this form if the 151.Fl c 152option is used. 153.It Ar file Ns Pa .a 154A library of object files, as produced by 155.Xr ar 1 , 156passed directly to the link editor. 157.It Ar file Ns Pa .o 158An object file produced by 159.Nm Fl c , 160and passed directly to the link editor. 161.It Fl l Ar library 162Search the library named 163.Pa lib Ns Ar library Ns Pa .a . 164A library will be searched when its name is encountered, so the 165placement of a 166.Fl l 167operand is significant. 168.El 169.Sh SEE ALSO 170.Xr ar 1 , 171.Xr c89 1 , 172.Xr cc 1 173.Sh STANDARDS 174The 175.Nm 176utility interface conforms to 177.St -p1003.1-2001 . 178Since it is a wrapper around 179.Tn GCC , 180it is limited to the C99 features that GCC actually implements. 181See 182.Em http://gcc.gnu.org/gcc-3.1/c99status.html . 183
