If no .Dq = Ns Ar value is given, a value of 1 will be used. Note that in order to request a translation as specified by .St -p1003.1-2001 , you need to define .Dv _POSIX_C_SOURCE=200112L either in the source or using this option. The .Fl D option has lower precedence than the .Fl U option. That is, if .Ar name is used in both a .Fl U and a .Fl D option, .Ar name will be undefined regardless of the order of the options. The .Fl D option may be specified more than once. .It Fl E Copy C-language source files to the standard output, expanding all preprocessor directives; no compilation will be performed. .It Fl g Produce symbolic information in the object or executable files. .It Fl I Ar directory Change the algorithm for searching for headers whose names are not absolute pathnames to look in the directory named by the .Ar directory pathname before looking in the usual places. Thus, headers whose names are enclosed in double-quotes .Pq Qq will be searched for first in the directory of the file with the .Ic #include line, then in directories named in .Fl I options, and last in the usual places. For headers whose names are enclosed in angle brackets .Pq Aq , the header will be searched for only in directories named in .Fl I options and then in the usual places. Directories named in .Fl I options shall be searched in the order specified. The .Fl I option may be specified more than once. .It Fl L Ar directory Change the algorithm of searching for the libraries named in the .Fl l objects to look in the directory named by the .Ar directory pathname before looking in the usual places. Directories named in .Fl L options will be searched in the order specified. The .Fl L option may be specified more than once. .It Fl o Ar outfile Use the pathname .Ar outfile , instead of the default .Pa a.out , for the executable file produced. .It Fl O Ar optlevel If .Ar optlevel is zero, disable all optimizations. Otherwise, enable optimizations at the specified level. .It Fl s Produce object and/or executable files from which symbolic and other information not required for proper execution has been removed (stripped). .It Fl U Ar name Remove any initial definition of .Ar name . The .Fl U option may be specified more than once. .El .Pp An operand is either in the form of a pathname or the form .Fl l library. At least one operand of the pathname form needs to be specified. Supported operands are of the form: .Bl -tag -offset indent -width ".Fl l Ar library" .It Ar file Ns Pa .c A C-language source file to be compiled and optionally linked. The operand must be of this form if the .Fl c option is used. .It Ar file Ns Pa .a A library of object files, as produced by .Xr ar 1 , passed directly to the link editor. .It Ar file Ns Pa .o An object file produced by .Nm Fl c , and passed directly to the link editor. .It Fl l Ar library Search the library named .Pa lib Ns Ar library Ns Pa .a . A library will be searched when its name is encountered, so the placement of a .Fl l operand is significant. .El .Sh SEE ALSO .Xr ar 1 , .Xr c89 1 , .Xr cc 1 .Sh STANDARDS The .Nm utility interface conforms to .St -p1003.1-2001 . Since it is a wrapper around .Tn GCC , it is limited to the .Tn C89 features that .Tn GCC actually implements.
