no compilation will be performed. 89.It Fl g 90Produce symbolic information in the object or executable files. 91.It Fl I Ar directory 92Change the algorithm for searching for headers whose names are not 93absolute pathnames to look in the directory named by the 94.Ar directory 95pathname before looking in the usual places. 96Thus, headers whose 97names are enclosed in double-quotes 98.Pq Qq 99will be searched for first 100in the directory of the file with the 101.Ic #include 102line, then in 103directories named in 104.Fl I 105options, and last in the usual places. 106For headers whose names are enclosed in angle brackets 107.Pq Aq , 108the header 109will be searched for only in directories named in 110.Fl I 111options and then in the usual places. 112Directories named in 113.Fl I 114options shall be searched in the order specified. 115The 116.Fl I 117option may be specified more than once. 118.It Fl L Ar directory 119Change the algorithm of searching for the libraries named in the 120.Fl l 121objects to look in the directory named by the 122.Ar directory 123pathname before looking in the usual places. 124Directories named in 125.Fl L 126options will be searched in the order specified. 127The 128.Fl L 129option may be specified more than once. 130.It Fl o Ar outfile 131Use the pathname 132.Ar outfile , 133instead of the default 134.Pa a.out , 135for the executable file produced. 136.It Fl O 137Optimize the compilation. 138.It Fl s 139Produce object and/or executable files from which symbolic and other 140information not required for proper execution has been removed 141(stripped). 142.It Fl U Ar name 143Remove any initial definition of 144.Ar name . 145The 146.Fl U 147option may be specified more than once. 148.El 149.Pp 150An operand is either in the form of a pathname or the form 151.Fl l 152library. 153At least one operand of the pathname form needs to be specified. 154Supported operands are of the form: 155.Bl -tag -offset indent -width ".Fl l Ar library" 156.It Ar file Ns Pa .c 157A C-language source file to be compiled and optionally linked. 158The operand must be of this form if the 159.Fl c 160option is used. 161.It Ar file Ns Pa .a 162A library of object files, as produced by 163.Xr ar 1 , 164passed directly to the link editor. 165.It Ar file Ns Pa .o 166An object file produced by 167.Nm Fl c , 168and passed directly to the link editor. 169.It Fl l Ar library 170Search the library named 171.Pa lib Ns Ar library Ns Pa .a . 172A library will be searched when its name is encountered, so the 173placement of a 174.Fl l 175operand is significant. 176.El 177.Sh SEE ALSO 178.Xr ar 1 , 179.Xr c99 1 , 180.Xr cc 1 181.Sh STANDARDS 182The 183.Nm 184utility is believed to comply with 185.St -p1003.2 . 186
