Binary Compatibility Module (BCM) for SCO UnixWare 2.1.x

     The Binary Compatibility Module (BCM) for SCO® UnixWare ® 2.1.x --
     UW2compat -- enables applications compiled on the UnixWare® 7.1.0
     UnixWare/OpenServer Development Kit (UDK) to be run on SCO UnixWare
     2.1.x systems.

System Requirements

 Software:  SCO UnixWare 2.1.3
 RAM:       N/A
 Disk Space:8MB

Installation

Perform the following steps as root:

  1. Download the product file from the ftp site.

  2. Install the BCM:

          pkgadd -d `pwd`/UW2compat.pkg

Important Notes

     Binary Compatibility Modules (BCMs) are created in conjunction with SCO
     UnixWare/OpenServer Development Kit (UDK) releases. For example, this
     BCM -- UW2compat Version 7.1.0 -- enables applications that were
     written and compiled with UDK Release 7.1.0.

     If the SCO Network Maintenance Supplement for UnixWare 2.1.3, PTF4001,
     is on the system, it must be removed before installing the UW2compat
     package. PTF4001 should then be reinstalled after UW2compat
     installation. If you later wish to remove the UW2compat, PTF4001 must
     be removed first. The UW2compat can then be removed, and PTF4001 should
     be reinstalled.

     For technical details about the contents of this BCM, see ``How the BCM
     works on SCO UnixWare 2.1.x''.

     For more information about the UDK, see the UDK documentation set on
     the SCO documentation server; click on Software Development.

How the BCM works on SCO UnixWare 2.1.x

     The compatibility module for SCO UnixWare 2.1.3 works by replacing
     certain existing (i.e., UnixWare 2.1.3) shared libraries with updated
     (i.e., UnixWare 7.1.0) versions, as well as installing the UDK tools.
     Both native UnixWare 2.1.3 binaries and UnixWare 7.1.0 compiled
     binaries use the updated libraries.

     Besides shared libraries, certain other files need to be part of the
     BCM. Such files would be any file that is part of the system and is
     visible to a running application. This includes, for example, locale
     files, configuration files, other data files like bitmaps, etc.

     You can do pkgrm UW2compat to restore the original shared libraries and
     configuration files.
