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 8c(1), as specified by the environment variable $objtype. The object files are then loaded using one of the loaders described in 8l(1). The options are:

-+
Accept C++ // comments.
-o out
Place loader output in file out instead of the default 8.out, v.out, etc.
-P
Omit the compilation and loading phases; leave the result of preprocessing name.c in name.i.
-E
Like -P, but send the result to standard output.
-c
Omit the loading phase.
-p
Insert profiling code into the executable output.
-w
Print compiler warning messages.
-W
Print all the messages that -w would print as warnings, but make them errors.
-llib
Include /$objtype/lib/ape/liblib.a as a library during the linking phase.
-B
Don't complain about functions used without ANSI function prototypes.
-V
Enable void* conversion warnings, as in 8c(1).
-v
Echo the preprocessing, compiling, and loading commands before they are executed.
-x file
Produce an export file in the executable, as described in 8l(1).
-Dname=def
-Dname
Define the name to the preprocessor, as if by #define. If no definition is given, the name is defined as 1.
-Uname
Undefine the name to the preprocessor, as if by #undef.
-Idir
#include files whose names do not begin with / are always sought first in the directory of the file argument, then in directories named in -I options, then in /$objtype/include/ape.
-N
Don't optimize compiled code.
-S
Print an assembly language version of the object code on standard output.
-T
Pass type signatures on all external and global entities. The signature is based on the C signof operator. See dynld(2).
-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.
-F
Enable vararg type checking as described in 8c(1). This is of limited use without the appropriate #pragma definitions.
-f
(ARM only) Generate VFP hardware floating point instructions.

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 routines, 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 cannot be implemented because the concept doesn't exist in Plan 9.
