This is what I would be interested in figuring out how to do, even with help, if that really helped things (again, see #9808; I agree with drkirkby that just to remove a few checks it isn't worth dropping a platform, though it sounds like he's also right about ATLAS checks being irrelevant). > Instead of this, it looks easier to require gfortran from the above be > installed (they provide binaries), just > as gfortran is required on Linux. As I point out in an earlier post, it isn't clear whether one can get "just" the fortran compiler out of the Tiger binaries, because they provide a custom gcc 4.2 - but Tiger in general only ships with 4.0.1. Some snooping indicates that one can use the gfortran 4.0.3 with gcc 4.0.1, but unfortunately FSF doesn't seem to provide its "prerelease" gfortran 4.0.1/3 available anywhere (Wikipedia says this was considered an alpha of sorts, though I don't know if this is to be trusted). Of course, this part may be rendered moot if the current discussion on #9808 proves fruitful; then drkirkby can at the very least remove references to G95 that have nothing to do with Darwin. - kcrisman -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
