Building OpenAFS on UNIX and LINUX
----------------------------------

A. Creating the proper directory structure.

   Uncompress the source into a directory of your choice.
   Preferrably, afs space. In the directory that you uncompressed the
   source in, you will only have an src directory.
	
   1. Make a directory for each system type that you plan on
      building. Current tested system types include the following
     (this step is skipped for the i386_nt40 system type):

      alpha_dux40/
      i386_linux22/
      rs_aix42/
      sun4x_56/
      sun4x_57/

      Example:
      % mkdir i386_linux22
      % ls -CF
      i386_linux22/     src/

      Builds for the following platforms will not fully compile:

      hp_ux110/
      sgi_65/

   2. Within each of those directories, create a dest/ and obj/ directory.

      Example:
      % mkdir i386_linux22/dest
      % mkdir i386_linux22/obj

   3. Create symbolic links to the system type you are about to build

      Example:
      % ln -s @sys/dest dest
      % ln -s @sys/obj  obj
      % ls -CF
      Makefile@     dest@     i386_linux22/     obj@     src/

   4. If this source is NOT in AFS space, You must make a link from
      @sys to your current system type. 

      Example:
      % ln -s i386_linux22 @sys

      Within AFS space, the AFS Cache Manager automatically
      substitutes the local machine's AFS system name (CPU/operating
      system type [ie: alpha_dux40, i386_linux22, ...]) for the @sys
      variable.

   5. Create the top level Makefile:
      a. For LINUX and UNIX versions

         Example:
         % ln -s src/Makefile Makefile
         % ls -CF
         Makefile@     i386_linux22/     src/

B  Building

   1. Make the obj links. This creates links from the @sys/obj/ tree
      back to the source tree. The source tree remains unchanged and
      builds are done in the platform specific object tree.

      % make links

   2. Begin building
      a. For Linux
         % make SYS_NAME="i386_linux22" LINUX_VERS="2.2.14"

      b. For UNIX versions, specify the system name as given by
         the system type defined in step A1.
         % make SYS_NAME="<system_name>"

         Example for the rs_aix42 operating system:
	 % make SYS_NAME="rs_aix42"
