DESCRIPTION
The c++ compilers, c++/?c, compile the named C++ files into
object files for the specified architecture (see 2c(1)).
They use cpp(1) as the preprocessor, cfront 3.0.1 as the C++
to C translator, and the appropriate C compiler such as 2c.
The c++ loaders, C++/?l, load object files using appropriate
object loaders (see 2l(1)) and patch, the C++ static con-
structor initializer.
The compilers and loaders use C++ and APE (ANSI C/POSIX)
include files and libraries.
Let the first letter of the base name of the compiler or
loader be O= 2, 8, k, or v.
The compiler options are:
-d Don't expand inline functions.
-o obj Place output in file obj (allowed only if there is
just one input file). Default is to take the last
element of the input path name, strip any trailing
.c, and append .O.
-v Print the version number of the compiler and the
commands as they are executed. A second -v causes
the commands that would be executed to be printed
without actually executing them.
-w Print warning messages.
-xfile Take cross compiling information from file. By
default, this information is taken from
/sys/lib/c++/O.sz.
-A Complain about functions used without a new-style

ANSI function prototype.
-B Turn off the action of the -A flag. This option
is on by default.
-Dname=def
-Dname Define the name to the preprocessor, as if by
`#define'. If no definition is given, the name is
defined as `1'.
-E Print the preprocessed version of the file on
standard output.
-F Print the preprocessed and cfronted version of the
file on standard output.
-Idir `#include' files whose names do not begin with `/'
are always sought first in the directory of the
file argument, then in directories named in -I
options, then in /$objtype/include/c++,
/sys/include/c++, /$objtype/include/ape, and
/sys/include/ape.
-O Perform object code optimization. This option is
on by default.
-N Turn off the action of the -O flag.
-S Print an assembly language version of the object
code on standard output.
-Uname Remove any initial definition of name.
-a Instead of compiling, print on standard output
acid functions (see acid(1)) for examining struc-
tures declared in the source files.
The loader options are:
-o out Place output in file out. Default is O.out.
EXAMPLE
To produce a MIPS executable prog from C++ files main.c,
sub.c, and using the task library:
c++/vc main.c sub.c
c++/vl -o prog main.v sub.v m.v -ltask

BUGS
The task library works only for the MIPS and the SPARC. The
Interrupt class is not yet supported. The source to the
translator is not included in the distribution.
