cc OPTIONS


SYNTAX:

Option
cc <option>

Description

-c
Compiles only; does not attempt to link
 source files.
-D name[=value]
Is passed to C compiler to assign the
 indicated value to the symbol name 
when the C preprocessor is run.
-f float
Specifies the floating point options that 
the compiler and linker use. The following
 should be supported:
-f -  - no floating point required
-f
 - emulated floating point
-fp
 hardware floating point 
(using 80x87 coprocessor)
-Idir
Search dir for included files whose names
 do not begin with a slash (/) prior to 
searching the usual directories. The
 directories for multiple -I options are
 searched in the order specified.
 The preprocessor first searches for 
#include files in the directory 
containing sourcefile, and then in
 directories named with -I options
 (if any), then /usr/ucbinclude,
 and finally, in /usr/include.
-Ldir
Add dir to the list of directories
 searched for libraries by 
 /usr/ccs/bin/ucbcc. This option is
 passed to /usr/ccs/bin/ld and /usr/lib.
 Directories specified with this option 
are searched before /usr/ucblib 
and /usr/lib.
-l library
If linking, adds the indicated library to
 the list of libraries to be linked.
-M
If linking, creates a map file with the 
same base name as the output 
executable, but with the suffix.map. This
 map file contains a list of symbols with
 their addresses.
-m model
Specifies the memory model that the 
compiler and linker use. The models
 may include:
-ms
small model
-mm
medium model
-ml
large model
-mf
flat model (32-bit)
-mc
compact model
-mh
huge model
-o output
If linking, places the executable output
 in the file output.
-S
Produces assembler listing with source
 code.
-Uname
Is passed to the C compiler, to undefined
 the symbol name.
-Y P, dir
Change the default directory used for
 finding libraries.
