What the Binary Compatibility Packages Are

The Solaris 2.x and OpenWindows Binary Compatibility Packages are optional packages available with the Solaris 2.x release. They allow existing SunOS 4.x applications, including OpenWindows applications, to run on the Solaris 2.x release without modification or recompilation. It handles most binary interface discrepancies between the two releases transparently, providing an operating environment where SunOS 4.x applications can run properly.
