Paul, I can/want2 help despite I tend to think that these series of great software are a nightmare to install as compared to all others. I've experienced many times that makefiles poorly work in general from one computer to another (same platform). I guess this is more time consuming for developers and direct compilation would be much more efficient. So making binaries for everybody is what every software people do, otherwise it is very discouraging because 99% of the people don't care for unix, windows and makefiles as we have tons of exafs data to reduce (and handy and very powerful software also exist on the market). all the best, Francois- -- Francois FARGES Laboratoire des Géomatériaux Université de Marne la Vallée 5 Bd Descartes-Champs S/Marne 77454 Marne la Vallée cedex 2 TEL: 01 49 32 90 57 from outside France: +33 1 49 32 90 57 FAX: 01 49 32 91 37 from outside France: +33 1 49 32 91 37
