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

A. Creating the proper directory structure.

   Uncompress the source into a directory of your choice. A directory
   in afs space is also valid. In the directory that you uncompressed the
   source in, you will only have an src/ directory.

   1. Pick a system to build for, and note its default AFS sys_name.
      A directory will be automatically created for binaries to be written 
      into with this name when you build.

      alpha_dux40
      alpha_dux50 (only tested on 5.0A)
      i386_linux22
      i386_linux24 (only tested with 2.4.0 kernel)
      rs_aix42
      sgi_65 (file server not tested)
      sun4x_56
      sun4x_57
      sun4x_58
      ppc_darwin_13
      alpha_linux_22 (DES does not work, will require one more change to
				compile)
      hp_ux110 (No client support, but db servers and utilities work)
      hp_ux102 (No client support, but db servers and utilities work)

   2. Using configure in the top level directory, configure for your
      AFS system type, providing the necessary flags:
      % ./configure --with-afs-sysname=sun4x_58

      For Linux systems you need also provide the patch in which your
      kernel headers for your configured kernel can be found. This should
      be the path of the directory containing a child directory named
      "include". So if your version file was 
      /usr/src/linux/include/linux/version.h you would invoke:
      % ./configure --with-afs-sysname=i386_linux24 --with-linux-kernel-headers=/usr/src/linux

      Currently you can build for only one Linux kernel at a time,
      and the version is extracted from the kernel headers in the root
      you specify.

      Be prepared to provide the switches --enable-obsolete and
      --enable-insecure if you require the use of any bundled but obsolete
      or insecure software included with OpenAFS. See README.obsolete and
      README.insecure for more details.

B  Building

   1. Now, you can build OpenAFS. 

      % make

      When the build completes, you will have a complete binary tree
      in the dest directory under the directory named for the sys_name you
      built for, e.g. sun4x_57/dest or i386_linux22/dest 

   2. As appropriate you can clean up or, if you're using Linux, build for
      another kernel version:
      a. To clean up:
         % make clean

      b. To build for another Linux kernel version:
         the system type defined in step A1.
         % ./configure --with-afs-sysname=i386_linux22 --with-linux-kernel-headers=/usr/src/linux-2.2.19-i686
         % make 

         Your dest tree will now include an additional kernel module for your
         additional kernel headers. Be aware that if the kernel version string
         which UTS_RELEASE is defined to in include/linux/version.h matches
         the last kernel you built for, the previous kernel module will be 
         overwritten.

C  Problems
   If you have a problem building this source, you may want to visit
   http://www.openafs.org/ to see if any problems have been reported 
   or to find out how to get more help.

   Mailing lists have been set up to help; More details can be found
