Description

Since many people complain about the ATLAS build in case they end up with a system without pre-tuned CPUs add this end-variable to skip over the ATLAS build.

Cheers,

The following patch should solve the problem of Pentium Ms which are misrecognized as CoreDuo?:

$ pwd
/tmp/atlas-3.8.p6/src/ATLAS/CONFIG/src/backend
$ diff -u archinfo_x86.c.orig archinfo_x86.c
--- archinfo_x86.c.orig 2008-01-09 23:43:59.000000000 +0100

       case  9:
       case 13:
          iret = IntPM;
+        break;
       case 14:
          iret = IntCoreDuo;
          break;

This should also solve (partly) #1547.

Hello Paul,

this is really an orthogonal issue, so I took your patch and made it #1740.

Removed [with patch] since Paul's patch is unrelated to this issue.

This is an important thing to do, building ATLAS takes too much time!

I add an optional SAGE_ATLAS_LIB keyword, which should be a directory containing libatlas.so, liblapack.so, libcblas.so, libatlas.so

The script that did link the libraries failed to link the headers. The spkg at #1787 will fix that.

Cheers,

Michael
