B.1 Option Syntax

The syntax of the cc command is:

% cc [options] filenames [libraries]...

where:

• options represents one or more of the options described in Table A–15.

• filenames represents one or more files used in building the executable program

  The C compiler accepts a list of C source files and object files contained in the list of files specified by filenames. The resulting executable code is placed in a.out, unless the -o option is used. In this case, the code is placed in the file named by the -o option.

  Use the C compiler to compile and link any combination of the following:

  • C source files, with a .c suffix

  • Inline template files, with a .il suffix (only when specified with .c files)

  • C preprocessed source files, with a .i suffix

  • Object-code files, with .o suffixes

  • Assembler source files, with .s suffixes

    After linking, the C compiler places the linked files, now in executable code, into a file named a.out, or into the file specified by the -o option. When the compiler produces object code for each .i or .c input file, it always creates an object (.o) file in the current working directory.

  libraries represents any of a number of standard or user-provided libraries containing functions, macros, and definitions of constants.

See option -YP, dir to change the default directories used for finding libraries. dir is a colon-separated path list. The default library search order for cc is:

/opt/SUNWspro/prod/lib

/usr/ccs/lib

/usr/lib

cc uses getopt to parse command-line options. Options are treated as a single letter or a single letter followed by an argument. See getopt(3c).
