Hi,
I'm trying to build sage 4.5.2 on a Sun Fire X4450 server (Intel Xenon
processors) running Redhat linux (Enterprise edition), and get an error when
building Atlas in the make script. Any comments are appreciated. Thanks,
I just tried building 4.5.3.alpha2 on *your* computer (rosemary) in
/home/wstein/build/sage-4.5.3.alpha2 and it worked fine. Note that I
set this environment variable:
export SAGE_FAT_BINARY=yes
This changes how ATLAS is built to use a sort of "lowest common
denominator" configuration.
You might try that. It can potentially make numerical linear algebra
slower for you, but I doubt
you do a lot of that.
It would be good if we knew the conditions on which this fails, so it could be
set automatically.
Have you any idea what the problem is on some machines?
I recently installed Debian - both 32-bit and 64-bit on VirtualBox virtual
machines. ATLAS would not build on either of them. It goes around the loop 5
times, trying to get consistent timing, then gives up.
Since I knew Minh had built on Debian many times on GCC build farm, I rather put
it down to something wrong with my Virtual machine setup.
