This distribution of MOSFLM v6.0 is slightly different from previous editions, as it includes the build for the Rossmann Fourier Auto-indexing routines, which are written mainly in C. You should be aware that there are some minor modifications to the RFA routines, so don't be tempted to install updates blindly from the Purdue site!

The program has been built successfully on the following machines; the "build times" refer to elapsed time while the machine has a typical load of users - in the case of the SGIs and the PC, that's one or two people; for the Alpha, it's nearer 40.

The Makefile in the top directory has checks for the environment variables PWD and HOSTTYPE; the different builds are all included in files in sub-directories according to the host type. You shouldn't need to touch the Makefiles at all, I hope (problems to the usual address...).

     Platform                          O/S              build time (min)
Alpha 275MHz, 1Gb                Digital UNIX               ~10
SGI 200MHz R4010/4400, 64Mb      Irix 5.3 (-Olimit unset)    ~8
SGI 175MHz R10000/R10010, 192Mb  Irix 6.2 (-Olimit unset)    ~4
 "    "        "     "      "      "   "  (-Olimit 3400)    ~18
PC 233MHz pentium, 128Mb         Red Hat Linux 5.1           ~7

The build will involve a lot of paging if your machine has limited RAM, as will running the program. The executable is ~3.0 - 3.6Mb, and integrating a single 8Mb image uses up to around 16Mb, so I'd guess that 32Mb RAM is about the minimum you'd want to use.

• LINUX only:

  1. The XDL_VIEW libraries from the CCP4 distribution are slightly broken, so these should be re-made first from the source files included here in the tar file XDL_VIEW.tar; it assumes that you have already set up the CCP4 environment variables according to the normal $CCP4/include/ccp4.setup route. Install the file libxdl_view.a in your normal $CLIB/ (CCP4 library directory), i.e. the same place as libccp4.a
  2. I've assumed that the X11 libraries are in /usr/X11R6/lib. If yours are in a different place, you'll have to modify the file mosflm/Makefile.i386-linux to suit.

• SGI only:

  1. Optimization in mosflm/Makefile.iris4d -Olimit 11400 might increase performance, but compilation takes forever. The line's there if you want to uncomment it, but my guess is that you'll lose more in the compilation than you'll ever gain in performance.

• SGI Irix 6.4 and Irix 6.5 only:

  1. If you are building on an SGI using either of these versions of Irix, you will need to do the following two steps prior to building MOSFLM.
     1. untar the file makefiles.tar after you have extracted all the other files in the distribution; this will over-write some of the distribution Makefiles.
     2. Set the environment variable HOSTTYPE to iris4d6.4 (not iris4d6.5).

        Under tcsh or csh, you would use the command

        	      % setenv HOSTTYPE iris4d6.4
        
        
        Under bash or ksh, you type
        
        	      %bash HOSTTYPE=iris4d6.4
        	      %bash export HOSTTYPE
        

     There are a few warnings generated during compilation, but these do not appear serious.

• Digital Unix 4.0 and a Powerstorm 4D60T graphics card:

  For some reason connected with colour mapping, the xdl_view routines do not work with this particular type of graphics card.

  When an image is to be displayed the following error message occurs:

  X Error of failed request:  BadMatch (invalid parameter attributes)
    Major opcode of failed request:  1 (X_CreateWindow)
    Serial number of failed request:  53
    Current serial number in output stream:  56
  

  FIX

  To get round this problem, replace the file "xdl_view.c" with the new version called "xdl_view_dec.c" which is in this directory, and remake the xdl_view library.

  The existing source code will be in a directory something like:

      /public/ccp4/x-windows/xdl_view/src
  

  This simply has some code commented out compared to the standard version, but this can lead to a degradation of the performance on some machines and so is only recommended if you are using this type of graphics card.
