[sage-devel] Sage 5.4 on ARM

2012-11-16 Thread Julien Puydt
Hi, I finished compiling sage 5.4 on ARM. I'll make a bdist available soon, and run "make ptestlong" afterwards (and report). The compilation went mostly fine ; the only caveat is that in libm4rie, conversion.c took hours to build, and wouldn't build with MAKE="make -j 3" because it was too

I run sage on my tablet (asus transformer prime) precisely in that way: over a ubuntu chroot. I have an old version installed though. I have an ubuntu 10 chroot, where i compiled sage 4.8 (it was a pain: over a week of comilation time). Later i tested version 5.1 over a very minimal newer version

Well, the main problem was overheating. Compilation failed several times, the device turned off by itself. I even think it got damaged, since the power button stopped working properly (luckily asus was kind enough to replace it) On 16 nov, 17:07, Julien Puydt wrote: > Le 16/11/2012 16:53, mmarco

Hey everyone, While I was looking at http://trac.sagemath.org/sage_trac/ticket/13556, I noticed what I believe to be a greater underlying problem with sage in that infinite sequences are not handled (gracefully). In particular, sage tries to construct infinite sequences/lists/tuples when give

Hi, In combinatorics on words, we often deal with infinite sequences, and there is code in Sage to deal with these things. After that, I don't know if the question you want to ask to those objects are the same as the problems considered in combinatorics on words (like, computing the factor com

Hey Andrew, Short version, the docbuild does not automatically update files as we expect it to. The surefire way to make sure the doc builds cleanly is to nuke the output/html directory and then rebuild the doc. I suspect we could delete key files in the output/html and get a partial rebuild.
