TITLE:              PTF193 - C++ Initialization/Termination Patch
DOCUMENT ID:        TID300134
DOCUMENT REVISION:  B
DATE:               25JAN95
ALERT STATUS:       Yellow
INFORMATION TYPE:   Symptom Solution
README FOR:         PTF193

PRODUCT and VERSION:
UnixWare 1.1

ABSTRACT:

This file contains PTF193 - C++ Initialization/Termination Patch. 
Installs redesigned C++ initialization and termination routines 
to resolve incompatibilities with assembler initialization and 
termination routines (contained in some 3rd party libraries).  
Also corrects an error in maintaining the list of destructors.  
This PTF can be installed on all UnixWare 1.1, 1.1.1, 1.1.2 or 
1.13 systems.  The C++ Compiler package must be installed in order 
to install this PTF.


SYMPTOM

The symptom of the incompatibility problem is that .init and .fini 
sections contained in 3rd party libraries are never executed.  The 
symptom of the destructor list problem is an endless loop when a 
constructor calls abort.

SOLUTION

Apply the ptf193 file.


Installation Instructions:

DATATYPE: datastream

1.  Download the ptf193.Z and ptf193.txt files to the /tmp directory  
    on your machine.

2.  Read the release notes contained in this file and follow the
    instuctions to add the packages to your system.

3.  Now become root, uncompress the file and add the package to your 
    system using the following commands:

        $ su
        # uncompress /tmp/ptf193.Z
        # pkgadd -d /tmp/ptf193 ptf193

Solution Specifics

General Description.
-------------------

The C++ initialization and termination routines have been redesigned 
and rewritten so that they are compatible with 3rd party libraries 
which contain .init and .fini routines.  The destructor list problem 
was resolved by insuring that the list is correct before each 
constructor is called.


New Features.
------------

None

Software Notes and Recommendations.
----------------------------------

This PTF can be installed on all UnixWare 1.1, 1.1.1, 1.1.2 or 
1.13 systems. The C++ Compiler package must be installed in order 
to install this PTF.

Assuming object files (.o) files are available, only a relink is needed to
incorporate the changes in C++ applications.

Hardware Notes and Recommendations.
----------------------------------

This PTF is targeted for the i386 and i486 CPU's.

Installation Instructions.
-------------------------

This PTF consists of 1 3.5 inch floppy.  Insert the floppy into the drive and,
while logged in as root, type

     pkgadd -d diskette1

and follow the instructions output by pkgadd.
