Installing the Compatibility Package

This package is optional that is, it is not automatically installed. This package is not required by any default SunOS 5.x commands, utilities, or libraries. Refer to Solaris Advanced Installation Guide or x86: Installing Solaris Software for instructions on how to install this package.

The contents of the compatibility package are installed into several directories, each corresponding to a default environment counterpart:

• /usr/ucb contains the source compatibility package commands. These commands existed in the /usr/bin, /usr/ucb, and /usr/etc directories in the SunOS 4.1 release.

• /usr/ucblib contains the source compatibility package libraries and SunOS/BSD system calls that are implemented here as library routines. These interfaces existed in /usr/lib in the SunOS 4.1 release.

• /usr/ucbinclude contains the source compatibility package header files. These files existed in the /usr/include directory in the SunOS 4.1 release.
