Lxrun

From Wikipedia, the free encyclopedia

The correct title of this article is lxrun. The initial letter is shown capitalized due to technical restrictions.

In Unix computing, lxrun is a compatibility layer to allow Linux binaries to run on UnixWare, SCO OpenServer and Solaris without recompilation. It was created by Mike Davidson. It has been an open source software project since 1997, and is available under the Mozilla Public License. Both SCO and Sun Microsystems began officially supporting lxrun in 1999.

[edit] Current Status

According to the official lxrun website [5], lxrun is now in "maintenance" mode, meaning that it is no longer being actively developed. Reasons cited for the declining interest in lxrun include the wide availability of real Linux machines, and the availability of more capable emulation systems, such as SCO's Linux Kernel Personality (LKP), OpenSolaris BrandZ, and various Virtual machine solutions. Newer Linux applications and host operating systems are not officially supported by lxrun.
