[sage-devel] Re: Broken optional packages...

2014-02-01 Thread Simon King

Hi William,

Zitat von William Stein :

2. Another broken package is

  p_group_cohomology

which doesn't build:

 pGroupCohomology/resolution.pxd:21:0: 'interrupt.pxi' not found

I don't know a fix.


I do, and it ''is'' fixed: See  
http://sage.math.washington.edu/home/SimonKing/Cohomology/p_group_cohomology-2.1.4.p1.spkg and trac ticket  
#15666.


As stated in comment 4, I would prefer to have this reviewed and fixed  
soon, so that it builds and works in recent Sage versions. Other items  
on the to do list, such as transition to the new spkg layout, are less  
urgent from my perspective, and is nothing that I'd have the capacity  
to do right now.


Best regards,
Simon

As per Volker's post (
https://groups.google.com/forum/#!topic/sage-devel/onWFAVz-LDA) these
packages need updated copyright information. The copyright for the sloane
database is provided in that thread, as is permission to use Andrew
Odlyzko's database, but for the others copyright information is still
needed.

One workaround is to do this:

Using this

sage -i topcom

works just fine for me. If you are doing

sage -i TOPCOM

you are probably getting the old spkg that doesn't work with the new layout
(this should really be fixed so that the packages are case-insensitive).

I don't know a fix.

[sage-devel] Broken optional packages...

2014-02-01 Thread William Stein
Hi,

I just wanted to raise awareness (and apologize) that the
re-organization of the layout of Sage broke so many optional spkg's.
In case people run into similar problems, here's what I'm doing to
workaround this mess for sage-6.2 in SageMathCloud.

1. These databases are broken:

cunningham_tables
database_jones_numfield
database_kohel
database_odlyzko_zeta
database_sloane_oeis
database_stein_watkins_mini.p0

One workaround is to do this:

 # in SAGE_ROOT
 ln -s local/share data

but the SAGE_DATA variable is gone as well... so you have to add this
*BACK* to src/bin/sage-env (after SAGE_SHARE):

# this is to be compatible with optional packages that haven't
# been updated to not use SAGE_DATA
export SAGE_DATA="$SAGE_SHARE"

(Hopefully, this can be added back or the packages fixed for sage-6.3.)

2. Another broken package is

  p_group_cohomology

which doesn't build:

 pGroupCohomology/resolution.pxd:21:0: 'interrupt.pxi' not found

I don't know a fix.

3. There's an optional package called pybtex which doesn't work.

The package TOPCOM-0.17.4 fails to build:

./spkg-install: line 11: cd:
/usr/local/sage/sage-6.1/spkg/standard/: No such file or directory

I don't know a fix.

This is all on Ubuntu 12.04 with pretty much anything imaginable installed.

Trac http://trac.sagemath.org/ticket/14962 is supposed to be about
packages broken by the git reorganization, but it's closed.

I tried the latest maxima built with GCL on ARM, and the output is
again different:
0.49801139449883

I asked on the maxima mailing list if they have an idea why this is 
so wildly different accross platforms and compilers...

You can fix it temporarily by doing the modification in
https://github.com/sagemath/sagenb/issues/195#issuecomment-33885044

The modification has to be made to the file

FWIW, maxima compiled with sbcl on amd64 agrees with the arm output
above.  Ie, exactly 16 digits.

Perhaps the issue is with ecls?

[sage-devel] Finite Elements Methods -packages in Sage

2014-02-01 Thread Sami Losoi
There are many open-source FEM packages which are good in one thing but bad 
in another.
So a good thing to do would be to make a package which uses the accurate 
parts of each single FEM -package.

Are there any plans to include some good code of finite element packages in 
Sage?

sagenb-0.10.8 (the latest sagenb) + sage-6.1.beta4 works fine. So, the 
bug is probably introduced in sage after the release of 6.1.beta4.

[sage-devel] Embedded LaTeX do not show up in Sage 6.1 notebook

Hi,

I've just made a fresh install of Sage 6.1 from the sources (via git clone) 
and noticed that LaTeX formulas in the notebook are not rendered by 
Mathjax: they remain between $ symbols, as they have been typed. This 
regards LaTeX formulas typed as comments in the text between the cells, not

color problem: there is some mix of blue and dark green). There are some 
error messages displayed in the console, which I copy below.

I tried with two different browsers (Firefox and Chromium). With Sage 6.0 
everything was OK. 
Do others have the same problem ?
