CC

NAME

SYNOPSIS

DESCRIPTION

CC assumes arguments ending in

.c

are C++ source programs; they are compiled, and each object program is left on the file whose name is that of the source with .o substituted for .c.

.s

are assembly source programs; they are assembled into .o files.

CC interprets the following options:

-n

Print what would have been done, but don't do it.

-v

Verbose mode. Print the commands as they are called.

-C

Prevent cpp and cfront from removing comments.

-E

Run only cpp on the .c files and send the result to standard output.

-F

Run only cpp and cfront on the .c files and send the result to standard output.

-Fc

Like the -F option, but the output is C source code suitable as a .c file for cc(1).

-.suffix

Instead of using standard output for the -E , -F or -Fc options, place the output from each .c file on a file with the corresponding .suffix.

-k

Keep the files __ctdt.c and __ctdt.o. They are used to initialize global and static class objects. Normally they are removed.

-NOMUNCH

Do not run nm and munch on the resulting object file. This phase is normally needed to detect static constructors and destructors.

+d

Suppress expansion of inline functions.

+e1,+e0

These flags affect how the compiler handles tables for virtual functions. +e1 causes the tables to be external and initialized; +e0 causes the tables to be external and uninitialized. If neither flag is specified (the default), the tables are local (static) and initialized. One file with all virtuals known to it should be compiled with +e1; the rest should be compiled with +e0. Having one external table may significantly reduce compile time, link time and object file size.

+I

Keep C source code produced by the front end in a ..c file. Line number information is stripped.

+V

Accept regular C function declarations; use the /usr/include directory for #include files. Support for this option is not guaranteed in future releases

+L

Generate source line number information using the format "#line %d" instead of "#%d".

+xfile

Read a file of sizes and alignments. Each line contains three fields: a type name, the size (in bytes), and the alignment (in bytes). This option is useful for cross compilation.

+S

Spy on cfront; that is, print some information on stderr.

If the file ".CCpath" exists in the current working directory, the first line is assumed to be a colon separated list of directories to be searched when trying to find '#include' files. If the file ".CCpath" doesn't exist, the environment variable CCPATH is used. All this is an alternative to the -I flag of cc(1).

If set, the environment variables ccpC (preprocessor), cfrontC (C++ front end), ccC (c compiler), assemblerC (assembler), linkerC (linker), and LIBRARY (C++ library) override the defaults.

See ld(1) for loader options, as(1) for assembler options, cc(1) for code generation options, and cpp(1) for preprocessor options.

DIAGNOSTICS

BUGS

There is a (temporary) hole in the C++ type system allowing C++ programs to use C libraries. When a name is overloaded the first function of that name (only) can be linked to a library compiled by cc. Thus, the declaration

overload read(int,char*,int), read(vector*);

will allow the system call read(2) to be used together with user defined functions of the same name. Use of this facility may lead to unexpected behavior. For example, had the other read() been declared first, or had the system's read() not been declared, then the user's read() would have been called by library functions like scanf(3).
