   5 The latest version was tested on a VMSAlpha7.2 system using DECC6.0, but
   6 probably also works for other versions.

   8 At the moment only the libraries LIBMESGL.EXE/LIBMESGL.OLB,
   9 LIBMESAGLU.EXE/LIBMESAGLU.OLB and LIBGLUT.EXE/LIBGLUT.OLB and the demos of the
  10 directory [.DEMOS] can be build.
  11 However, feel free to create the missing "decrip.mms-files" in the other
  12 directories.

  14  The make files were tested
  15 using the DIGITAL make utility called MMS.  There is also a public domain
  16 clone available (MMK) and I  think, but it is not tested, that this
  17 utility will give (hardly) any problem.
  18
  19 To make everything just type MMS (or MMK) in the main directory of
  20 mesagl.  For MMS the deafult makefile is called descrip.mms, and
  21 that is what I have called it.  I included alse some config files,
  22 all having mms somewhere in the name which all the makefiles need
  23 (just as your unix makefiles).
  24
  25 On Alpha platforms at default a sharable images for the libraries are created.
  26 To get a static library make it by typing MMS/MACRO=(NOSHARE=1).
  27 On VAX platforms only static libraries can be build.

  30 changed default compilation to use /float=ieee/ieee=denorm. The reason for
  31 this is that it makes Mesa on OpenVMS better compatible with other platforms
  32 and other packages for VMS that I maintain.

  36 You may want to compile Mesa to use VAX-floating point arithmetic, instead
  37 of IEEE floating point by removing the /float=IEEE/denorm flag from the
  38 compiler options in the descrip.mms files.
