UnixWare ® 7.1.1

The "UnixWare and OpenServer Development Kit" Delivers Maximum Investment Protection For Your Applications

Whether you are a long-time UNIX®/C/C++ programmer or a cutting edge Java™ developer, the UDK gives you the tools, the performance and the right price for creating robust, high-performance applications on the most advanced, high-volume operating system on Intel processor-based servers.

Versions of the UDK tools are supported for installation and use on UnixWare 7, SCO OpenServer Release 5 and SCO UnixWare 2.1.3 operating systems. Because these UnixWare 7 development tools are available on the current SCO platforms, developers using those platforms can get access now to the advanced features provided by the UDK including C++ exception handling, 64-bit integers, support for Java™ native methods and more.

The UDK provides a complete set of Java™ tools that will satisfy even the most demanding professional developers. Java Development Kit (JDK) versions provide rich Java and web-development capabilities whether you are a Java™ expert or a novice web application designer. The Just-In-Time (JIT) compiler provides the performance boost needed by certain Java server and client applications.

UDK Features: Generates single binary for all current SCO UNIX® platforms; extensive Java™ development tools; support for 64-bit "long long" data type; Pentium®, Pentium Pro, Pentium II, and Pentium III performance optimizations; enhanced graphical debugger; high performance C++ exception handling and numerous C and C++ enhancements including language standards conformance.


  • Single development environment for all current SCO Operating Systems
  • Creates a single binary for SCO OpenServerô Release 5, SCO UnixWare 2.1.3 and UnixWare 7 operating systems
  • Full-featured Java™ development environment including:
    JDK 1.1.8
    Java 2 Release 1.2.2 DK
    Just-In-Time Compiler (JIT)
    Support for 64-bit programming ("long long" data type)
    Compatibility libraries and commands for existing OpenServer and UnixWare applications
    Extensive APIs and tools for TCP/IP networking, graphics and application packaging
  • Multi-threaded graphical and character debugging
  • Performance profiling and optimization tools
  • Extensive web-based product documentation


  • Economy: Developers need only one binary for all SCO releases
  • Compatibility: businesses can maintain legacy or current applications while adding Java™ or other new components
  • Flexibility: use any current SCO UNIX® platform as base development system
  • Java technology: powerful, cost-effective implementation of Sun® Java development platform available Investment protection via standards: promotes both long time UNIX® system standards (POSIX, FIPS, et al.) and emerging standards (Java™, IPv6, et al.)
  • Easy Migration: developers and users can upgrade to UnixWare 7 at their own speed. Applications written now will run on UnixWare 7 when the time comes.
