NAME

       pcc - APE C compiler driver

SYNOPSIS

       pcc [ option ...  ] [ name ...  ]

DESCRIPTION

       Pcc  compiles and loads C programs, using APE (ANSI C/POSIX) include files and libraries.  Named files ending with .c are preprocessed with
       cpp(1), then compiled with one of the compilers described in 2c(1), as specified by the environment variable $objtype.	The  object  files
       are then loaded using one of the loaders described in 2l(1).  The options are:

       -o out	   Place loader output in file out instead of the default 2.out, v.out, etc.

       -P	   Omit the compilation and loading phases; leave the result of preprocessing name.c in name.i.

       -c	   Omit the loading phase.

       -p	   Insert profiling code into the executable output.

       -w	   Print compiler warning messages.

       -B	   Don't complain about functions used without ANSI function prototypes.

       -v	   Echo the preprocessing, compiling, and loading commands before they are executed.

       -Dname=def
       -Dname	   Define the name to the preprocessor, as if by If no definition is given, the name is defined as

       -Uname	   Undefine the name to the preprocessor, as if by

       -Idir	   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/ape.

       -N	   Don't optimize compiled code.

       -S	   Print an assembly language version of the object code on standard output.

       -a	   Instead of compiling, print on standard output acid functions (see acid(1)) for examining structures  declared  in  the  source
		   files.

       -aa	   Like -a except that functions for structures declared in included header files are omitted.

       The APE environment contains all of the include files and library routines specified in the ANSI C standard (X3.159-1989), as well as those
       specified in the IEEE Portable Operating System Interface standard (POSIX, 1003.1-1990, ISO 9945-1).  In order to  access  the  POSIX  rou-
       tines, source programs should define the preprocessor constant _POSIX_SOURCE.

FILES

       /sys/include/ape
	      directory for machine-independent #include files.

       /$objtype/include/ape
	      directory for machine-dependent #include files.

       /$objtype/lib/ape/libap.a
	      ANSI C/POSIX library.

BUGS

       The locale manipulation functions are minimal.  Signal functions and terminal characteristic handlers are only minimally implemented.  Link
       always fails, because Plan 9 doesn't support multiple links to a file.  The functions related to setting effective user and group ids  can-
       not be implemented because the concept doesn't exist in Plan 9.
