53a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgThe latest version was tested on a VMSAlpha7.2 system using DECC6.0, but
63a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgprobably also works for other versions.

83a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgAt the moment only the libraries LIBMESGL.EXE/LIBMESGL.OLB,
93a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgLIBMESAGLU.EXE/LIBMESAGLU.OLB and LIBGLUT.EXE/LIBGLUT.OLB and the demos of the
103a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgdirectory [.DEMOS] can be build.
113a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgHowever, feel free to create the missing "decrip.mms-files" in the other
123a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgdirectories.

143a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.org The make files were tested
153a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgusing the DIGITAL make utility called MMS.  There is also a public domain
163a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgclone available (MMK) and I  think, but it is not tested, that this
173a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgutility will give (hardly) any problem.

193a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgTo make everything just type MMS (or MMK) in the main directory of
203a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgmesagl.  For MMS the deafult makefile is called descrip.mms, and
213a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgthat is what I have called it.  I included alse some config files,
223a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgall having mms somewhere in the name which all the makefiles need
233a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.org(just as your unix makefiles).

253a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgOn Alpha platforms at default a sharable images for the libraries are created.
263a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgTo get a static library make it by typing MMS/MACRO=(NOSHARE=1).
273a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgOn VAX platforms only static libraries can be build.

303a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgchanged default compilation to use /float=ieee/ieee=denorm. The reason for 
313a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgthis is that it makes Mesa on OpenVMS better compatible with other platforms
323a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.organd other packages for VMS that I maintain.

363a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgYou may want to compile Mesa to use VAX-floating point arithmetic, instead
373a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgof IEEE floating point by removing the /float=IEEE/denorm flag from the
383a0db227ffe90888ad760c61a63226988c974e0apatrick@chromium.orgcompiler options in the descrip.mms files.
