This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open This is an old article about SCO Unix running Unixware binaries with osrcompat and is only left here for historical purposes. There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.

Can Unixware 7 programs run on SCO Unix OSR5?

Maybe, but definitely not without the OSRcompat package. This package provides the libraries and hooks necessary to run Unixware 7 binaries.

Note that binary compatibility doesn't guarantee a working program. The program's code can be looking for particular directory structures, expecting certain PATHS, or be expecting particular behaviour from system commands. Those problems hold true in the other direction also: while OSR5 binaries will run on Unixware 7, a particular application may not.

You can install OSRcompat from the Unixware/Openserver Development Kit CD or download it from https://www.sco.com/download (it's the "Binary Compatibility" module). Note that it is installed with pkgadd, not custom.
