P2CC(1)								       P2CC(1)

NAME
       p2cc - Pascal compiler using p2c

SYNOPSIS
       p2cc [ options and files ]

DESCRIPTION
       P2cc  is	 a  Pascal compiler that works by running p2c, the Pascal to C
       translator, followed by cc, the C compiler.

       All command-line options and arguments are passed  directly  to	the  C
       compiler,  except  that files ending with .p or .pas are passed through
       p2c first, and that the options listed below are interpreted  specially
       by  p2cc.   As usual, programs made up of several source modules can be
       compiled all on one p2cc command, or separately using p2cc -c and  then
       linked afterwards with a final p2cc command.

OPTIONS
       -p2c   Translate	 .p and .pas files to C but do not compile the result‐
	      ing .c files.  This is analogous to the -S  and  -c  options  of
	      most  C compilers, which stop with assembly language or unlinked
	      object files, respectively.

       -p2coption
	      Pass option to p2c rather than to the C compiler.

       -O     This switch is passed on to the C compiler  to  enable  optional
	      optimization  of the program.  It also instructs p2c to do a few
	      optimizations of its own, e.g., disabling certain run-time range
	      checks.

       -Idir  The -I switch is passed to both p2c and the C compiler, where it
	      will identify places to look for Pascal interface texts or C  .h
	      files, respectively.

       -v     Enable  "verbose"	 mode.	 This  affects both p2c and the C com‐
	      piler.

ENVIRONMENT
       The following environment variables may be used to affect the operation
       of p2cc.

       P2CC_PAT
	      This  variable  holds  a	regular expression for recognizing the
	      names of Pascal files.  By default, it recognizes strings	 which
	      end in .p or .pas.

       P2CC_CC
	      This  holds  the	name  of  the  command	to run the C compiler.
	      Default is cc.

       P2CC_CCOPTS
	      This holds additional arguments to be passed to the cc  command,
	      before the names of any source files.

       P2CC_CCOPTS2
	      These  arguments are passed to the cc command after the names of
	      source files.

       P2CC_LIBP2C
	      This is the name of the libp2c.a file holding p2c	 runtime  rou‐
	      tines.   Its  default  is -lp2c, which causes the linker to look
	      for libp2c.a in the usual places for libraries.

       P2CC_P2C
	      This holds the name of the command to run p2c.   It  is  p2c  by
	      default.

       P2CC_P2COPTS
	      These  are  arguments  to	 be passed to p2c on the command line.
	      The default specifies -comp, which set the defaults for  various
	      p2c  configuration  options  to be more suitable for compilation
	      rather than translation, and -local, which sets other options to
	      work on the assumption that the output from p2c will be compiled
	      and run on the same type of machine that ran p2c itself.

       P2CC_SUFFIX
	      This is the suffix to use for the names of  temporary  C	source
	      files.   The default is ..c, ensuring that p2c will not inadver‐
	      tently erase .c files in the same directory as the Pascal source
	      files.   Note  that  if  the  -p2c option is used, the suffix is
	      forced instead to .c since the user has explicitly asked	for  C
	      source files.
