Sun's Solaris™ Operating Environment Runs Linux Applications

PALO ALTO, CA - May 12, 1999 - Sun Microsystems, Inc. today announced compatibility between the Solaris™ operating environment and Linux applications. Sun contributed software to an open source development effort that allows users to run Linux applications on the Solaris 7 operating environment expanding the number of available applications. In addition, Sun will provide free development tools that make it easy for developers to ensure source code compatibility between Linux and the Solaris operating environment.

"Linux and other open source products have brought renewed vitality to the industry," said Rob Gingell, chief technology officer, Solaris Software, Sun Microsystems, Inc. "Increased sharing of technology within the Solaris and Linux communities will accelerate the adoption of open computing and further fuel innovation in the software development community, creating benefits for both customers and developers."

Sun collaborated with the open development community to provide software enhancements to a popular Linux compatibility program, known as lxrun. With lxrun for the Solaris Intel Platform Edition, commercially or internally developed Linux applications run unmodified along with Solaris applications.

"Sun's cooperation has significantly furthered the lxrun open-development effort," said Steve Ginzburg, lxrun source code maintainer. "Sun's technical contributions have already proven invaluable, and their continued involvement will increase the visibility and accessibility of lxrun. I am excited about continuing this mutually beneficial relationship."

Sun's new software tools help Linux developers simplify and streamline the process of developing applications across both the Linux and Solaris platforms. The offerings for the SPARC™ and Intel platforms include how-to guides and tools that analyze source code compatibility to enable applications to run smoothly on Linux and Solaris software.

Sun plans to showcase Linux development efforts at this month's LinuxExpo (May 18-22) including a demonstration of Linux applications running unmodified on the Solaris operating environment and Linux running on the UltraSPARC™ architecture.
