[sage-support] Re: using the system version of Python from the sage notebook?
Another similar question involves using the local version of GAP in place of the supplied one. Apart from the fact that Sage is distributed with an old and (a bit) broken version of GAP, (well, I know that I can install a newer version by downloading the corresponding update) having two copies of GAP is awkward, just given the fact that a full installation of GAP with all the packages and libraries is quite huge. (well, maybe it is psychological difficulty, as I use (and occasionally develop small bits of) GAP since 1994... :)) Best, Dmitrii On Nov 30, 12:40 am, tmbdev wrote: > Sage supports all sorts of "external" tools, like R and Octave. > > I would like to be able to use the installed version of Python with > the Sage notebook interface (in place of its built-in one).

If you could use the system Python, that would fix that problem too, wouldn't it?

For quite a while we had to patch GAP so that it would work with the Sage interface. I'm curious -- what in particular is broken about GAP-4.4.10? We tried to ship 4.4.12, but found it to be "more broken"; in particular, it didn't work on Itanium Linux boxes, which is one of our officially supported platforms. -- William -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
Re: [sage-support] Re: using the system version of Python from the sage notebook?
William, Patch 11 of GAP 4.4 fixes a dozen of critical level bugs, ie bugs that potentially lead to wrong results! Eg getting wrong character tables, wrong results in range intersection... If a platform, like Itanium, was dropped, it is likely for a jolly good reason. IMHO distributing a clearly buggy version is a very bad idea.

not quite.
After I do this, (on Sage updated with gap-4.4.12.p2.spkg)
I can run my local GAP installation, but
gap_reset_workspace

I tried to reproduce your problem on an Itanium cluster at U.Waterloo, by installing and trying out GAP-4.4.12 there, but it just works... (gcc-4.1.2, the usual GAP optimisation level (O2?)) Should I try building Sage there? (Indeed, it does not really work with Intel's icc 10.1 (only O0, which is too slow), but do you need icc that badly? We can look into this, if needed, it's probably a minor assembler issue...) Here are the details of the working setup: pilatus:~/gap/gap4r4> gcc -v Using built-in specs.
