Description (last modified by )
There are some problems with generic binaries (SAGE_FAT_BINARY=yes
) in the new ATLAS spkg. In order not to delay the release of Sage 5.10 any longer, I will revert #10508.
Fixing the issues below (and upgrading ATLAS to 3.10.x) is #14754.
On cicero (Fedora 16 i686), the build fails: http://build.sagemath.org/sage/builders/Skynet%20cicero%20%28Fedora%2016%20i686%29%20bin/builds/90/steps/shell_5/logs/atlas
Note the use of -DATL_3DNow
and lots of "Illegal instruction" messages, proving that this likely is not a generic binary, unlike what it should be.
On arando (Ubuntu 13.04 i686), the build works but there is doctest failure:
sage -t devel/sage/sage/matrix/matrix_double_dense.pyx ********************************************************************** File "devel/sage/sage/matrix/matrix_double_dense.pyx", line 3823, in sage.matrix.matrix_double_dense.Matrix_double_dense.is_positive_definite Failed example: H.is_positive_definite() Expected: True Got: False **********************************************************************

Replying to jpflori:
The fact that 3DNow is used was discussed at #13706.
Of course we can remove that.
Jeroen: could you try to modify spkg-install: replace
isa_ext = ('3DNow',)by
isa_ext = ()on line 404 (in some version of the p0 spkg I have access to right now.) It's in the configure_base function, the part about "Generic configuration on Intel i386 compatible CPUs"; and then try to rebuild on cicero? (I have no access to it)
I posted a spkg at #14754 doing that, I'll try it on cicero (a single-core Pentium 4 machine).
In any case, this will not change my decision to revert #10508. I want to release Sage 5.10 as soon as possible.
