Requirements for Building STAF

To build STAF, you need to install the following software based on the operating system where you are building:

    * Windows
          o Cygwin - Cygwin is a UNIX environment for Windows. It can be downloaded from http://www.cygwin.com.
          o Microsoft Visual C++ 6.0, or Microsoft Visual C++ 7.0, or the February 2003 Platform SDK (if you are building IA-64 code or STAF IPv6 Support)
    * Linux and Solaris
          o GCC 2.95.2 or later
          o GNU Make 3.78 or later
    * AIX
          o xlC V5 or later
          o GNU Make 3.78 or later
    * HP-UX
          o aCC 3.25 or later
          o GNU Make 3.78 or later

To build the Java interface component of STAF and to build any STAF services written in Java, you need to install Java. Currently, we are mostly using Java 1.4.2 (IBM or Sun), but also support other versions of Java, including Java 1.5.0.

To build the REXX interface component of STAF, you need to install REXX.
