cc

cc [options] files

Compile one or more C source files (file.c), assembler source files (file.s), or preprocessed C source files (file.i). cc automatically invokes the link editor ld (unless -c is supplied). In some cases, cc generates an object file having a .o suffix and a corresponding root name. By default, output is placed in a.out. cc accepts additional system-specific options. Note: This command runs the ANSI C compiler; use /usr/bin/cc if you want to run the compiler for Kernighan and Ritchie's C.

Options

-#

Show when each compiler tool is invoked. Solaris 2.0 only.

-A name[(tokens)]

Supply an #assert directive, assigning name with optional tokens as parameters.

-A -

Ignore predefined assertions and macros.

-B mode

Use with one or more -l options to tell ld what type of library files to search. When mode is dynamic, libraries are shared, meaning that library files ending in both .so and .a are searched. When mode is static, only .a files are searched. To restore the previous search mode for additional -l options, supply -B again and change its mode.

-C

Do not strip comments during preprocessing.

-c

Suppress link editing and keep any object files that were produced.

-D name[=def]

Supply a #define directive, defining name to be def or, if no def is given, the value 1.

-dc

Tell ld to link dynamically when c is y (the default) or to link statically when c is n.

-dalign

Produce double load/store instructions to improve performance. Solaris 2.0 only.

-E

Run only the macro preprocessor, sending results to standard output.

-fast

Use cc options that give fastest compilation. Solaris 2.0 only.

-flags

Briefly describe available options. Solaris 2.0 only.

-fnonstd

Produce SIGFPE signals for floating-point overflows and division by zero. Solaris 2.0 only.

-fsingle

Evaluate float expressions as single-precision. Solaris 2.0 only.

-G

Produce a shared object instead of a dynamically linked executable.

-g

Generate more symbol-table information needed for debuggers dbx (Solaris) or sdb (SVR4).

-H

List (on standard error) the pathnames of header files used in C files.

-I dir

Search for include files in directory dir (in addition to standard locations). Supply a -I for each new dir to be searched.

-K word

If word is PIC, produce position-independent code; if word is minabi, compile with the minimum dynamic linking that preserves ABI conformance.

-keeptmp

Don't delete temporary files. Solaris 2.0 only.

-L dir

Like -I, but search dir for library archives.

-l name

Link source file with library files libname.so or libname.a.

-O

Optimize object code (produced by .c or .i files).

-o file

Send object output to file instead of to a.out.

-P

Run only the preprocessor and place the result in file.i.

-p

Generate benchmark code to count the times each routine is called. File mon.out is created, so prof can later be used to produce an execution profile.

-Qc

List in the output (c = y) or do not list (c = n) information about the compilation tools invoked. Default is to list.

-ql

Invoke the basic block analyzer and produce code to count the times each source line is executed. Use lprof to list the counts.

-qp

Same as -p.

-S

Compile (and optimize, if -O is supplied), but don't assemble or link; assembler output is placed in file.s.

-U name

Remove definition of name, as if through an #undef directive.

-V

Print version information for compiler tools.

-v

Check semantics strictly, and allow some lint constructs to work.

-W[p02abl],arg1[,arg2...]

Each comma-separated argument is a command-line token (option, parameter) from cc. -W hands off these arguments to allow separate processing by a particular compiler tool. p or 0 specifies the compiler; 2, optimizer; b, basic block analyzer; a, assembler; l, link editor.

-Xc

Set c as the level of ANSI C compliance:

t

Transition (default). Source code must comply with pre-ANSI features.

a

ANSI. Code must comply with ANSI features, but doesn't warn about new escape sequences or trigraphs.

c

Conformance. More rigorous than a.

s

Code is allowed to be old Sun C. Solaris 2.0 only.

-xpg

Like -p, but produce file gmon.out; use gprof to produce an execution profile. Solaris 2.0 only.

-xsb

Produce symbol-table data for Source Code Browser. Solaris 2.0 only.

-xsbfast

Same as -xsb, but don't actually compile. Solaris 2.0 only.

-xstrconst

Add string literals to text segment, not data segment. Solaris 2.0 only.

-Yc,dir

Specify that item c is searched in directory dir. c can be p, 0, 2, a, b, or l, as explained under -W. c can also be:

I

Include files to search last for (see -I).

P

Libraries; dir is a list of directories, separated by a colon (see -L).

S

Startup object files.

Example

Compile xpop.c and link it to the X libraries:

cc -o xpop xpop.c -lXaw -lXmu -lXt -lX11
