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 ("") will be searched for first 98in the directory of the file with the 99.Ic #include 100line, then in 101directories named in 102.Fl I 103options, and last in the usual places. 104For 105headers whose names are enclosed in angle brackets (<>), the header 106will be searched for only in directories named in 107.Fl I 108options and then in the usual places. 109Directories named in 110.Fl I 111options shall be searched in the order specified. 112The 113.Fl I 114option may be specified more than once. 115.It Fl L Ar directory 116Change the algorithm of searching for the libraries named in the 117.Fl l 118objects to look in the directory named by the 119.Ar directory 120pathname before looking in the usual places. 121Directories named in 122.Fl L 123options will be searched in the order specified. 124The 125.Fl L 126option may be specified more than once. 127.It Fl o Ar outfile 128Use the pathname 129.Ar outfile , 130instead of the default 131.Pa a.out , 132for the executable file produced. 133.It Fl O 134Optimize the compilation. 135.It Fl s 136Produce object and/or executable files from which symbolic and other 137information not required for proper execution has been removed 138(stripped). 139.It Fl U Ar name 140Remove any initial definition of 141.Ar name . 142The 143.Fl U 144option may be specified more than once. 145.El 146.Pp 147An operand is either in the form of a pathname or the form 148.Fl l 149library. 150At least one operand of the pathname form needs to be 151specified. 152Supported operands are of the form: 153.Bl -tag -offset indent -width "-l library" 154.It Ar file Ns Pa .c 155A C-language source file to be compiled and optionally linked. 156The 157operand must be of this form if the 158.Fl c 159option is used. 160.It Ar file Ns Pa .a 161A library of object files, as produced by 162.Xr ar 1 , 163passed directly to the link editor. 164.It Ar file Ns Pa .o 165An object file produced by 166.Nm Fl c , 167and passed directly to the link editor. 168.It Fl l Ar library 169Search the library named 170.Pa lib Ns Ar library Ns Pa .a . 171A library will be searched when its name is encountered, so the 172placement of a 173.Fl l 174operand is significant. 175.El 176.Sh SEE ALSO 177.Xr ar 1 , 178.Xr cc 1 179.Sh STANDARDS 180The 181.Nm 182command is believed to comply with 183.St -p1003.2 . 184
