This is an improved version of the c-compiler wrapper which was posted
quite a while ago. This version allows curses programs to be compiled
using the shared libraries on the UNIX-PC. This is also set up as an
Installable File for those of you who don't think that the User Agent
is the worst thing since DOS. For more info., read the README file.
I hope you find this useful. Personally, besides "windy", this is the
most useful add-on program I have on my system. My sincere thanks to
Arnold Robbins and Emmet Gray for their original contributions.

XThe enclosed files provide a updated c-compiler interface for the UNIX-PC
Xwhich automates the use of the shared libraries when compiling programs on
Xthis machine.
X
XCredit for the initial idea of a compiler interface goes to Arnold Robbins
Xof Emory University Computing Center who distributed the original interface
Xprogram. To this original work I have done the following:
X
X - Added and/or modify support for -[CUefouLW] & -VS flags
X - Expanded comments throughout the script for reradability.
X - Performed some minor reorganization for clarity.
X - Modified the script so as not to rename /bin/cc. Instead, this
X script is called /bin/ccc and it references the original cc.
X - Added a test which prevents the loader-step from starting up if
X an error occurs in the compiling stage. Prior to this, linking
X would be attempted even if one of the .o files was missing.
X
X
XRecently, Emmet Gray of the US Army HQ III Corp sent out a script for
Xmodifying the /lib/shlib.ifile to allow curses programs to be compiled
Xusing the shared libraries. This was a great idea but I found three
Xadditions which I wanted to make:
X
X (1) I wanted a permenant copy of the edited .ifile so that I didn't
X have to re-edit the original file each time I compiled a curses
X program.
X
X (2) I found that there were a few routines contained in /lib/libc.a
X which were not duplicated in the shared libraries but which
X were required by the curses library /usr/lib/libcurses.a.
X
X (3) I wanted curses programs to compile transparently like any
X other program - which meant modifying /bin/ccc to handle the
X work.
X
X
XFinally, I like the way that the UNIX-PC keeps track of installed software
Xby hiding a Remove script which cleans up if you decide to remove the
Xthe software at a later date. So what you have here is a set of files
Xto make a UNIX-PC Installable File. To Install this program:
X
X 1: Unshar this package
X
X 2: Type: make
X
X 3: Use the "Install Software sent by Electronic Mail" item in
X the "Software Setup" menu from the "Administration" menu
X to install the file "CCC". This step will allow you to
X create a Backup Installable Floppy if you decide you
X would like it.
X
X 4: Use "ccc" just as you would "cc". In your Makefiles, define
X CC=/bin/ccc to force make to use the interface program.
X
X (For those of you not running the User Agent, you can install
X this program by: 1: become root [su root]
X 2: Type: sh Install
X 3: Keep a copy of the Remove file if you like.)
X
X
XI have compiled a number of curses program using this modified script and
Xhave encountered no problems to date. Should you find any problems with
Xthis script and support files, I would appreciate hearing about them.

X# Program: /bin/ccc (Bourne Shell Script) #
X# Version: 1.2 #
X# #
X# Original Coding: Arnold Robbins - Emory Univ. Computing Center #
X# #
X# SYNOPSIS #
X# ccc [ options ] file [ file ... ] #
X# #
X# DESCRIPTION #
X# "ccc" is an interface for the standard C-compiler (/bin/cc) on #
X# the AT&T UNIX-pc (aka 3B1) which allows a more natural usage of #
X# the shared library facilities on this machine. #
X# #
X# To use this script, you must: #
X# 2: Install this script as /bin/ccc #
X# #
X# You may use this replacement "ccc" as you would the original #
X# with the added benefit that programs will now be compiled using #
X# the shared library. #
X# #
X# REVISION HISTORY #
X# 09-10-87 V1.0: Jeffery Small (uunet!hsi!cjsa!jeff) #
X# - Add/modify support for -[CUefouLW] & -VS flag #
X# - Expanded comments #
X# - Performed some minor reorganization. #
X# 09-22-87 V1.1: Jeffery Small (uunet!hsi!cjsa!jeff) #
X# - Modified script to leave /bin/cc alone #
X# - Rename this script to /bin/ccc #
X# - Prevent loader-step from starting if an error #
X# occurs in the compiling stage. #
X# 01-20-88 V1.2: Jeffery Small (uunet!hsi!cjsa!jeff) #
X# - Added support to allow curses programs to be #
X# compiled with the shared library. This #
X# requires the following two support files. #
X# (1) /lib/shlib.iCURSES - edited version of #
X# /lib/shlib.ifile modified to eliminate #
X# conflicts with the curses library. Idea #
X# credits to Emmet P. Gray (fthood!egray) #
X# (2) /lib/libCURSES.a - missing routines #
X# from /lib/libc.a not defined by the #
X# shared libraries. #
