sysop@atrium.UUCP (Joseph) (02/04/88)
I've received several requests on how I solved the problem with implementing
shared libraries and curses together. Below is Jeffery Small's ccc shell
script which will compile your programs with the shared libraries and if you
add -lcurses to the command line, it will add the curses library also.

# This is a shell archive. Remove anything before this line
# then unpack it by saving it in a file and typing "sh file"
# (Files unpacked will be owned by you and have default permissions).
# This archive contains the following files:
# ./README
# ./Size
# ./Name
# ./Files
# ./Install
# ./Remove
# ./Makefile
# ./ccc
#
if `test ! -s ./README`
then
echo "extracting ./README ..."
sed 's/^X//' > ./README << 'END__of_the__FILE'
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. #
