Re: [sage-devel] Problem building GSL in cygwin64

The LDConvert error must be some LongDouble stuff not guarded correctly with #if HAS_LONG_DOUBLE (or a variation thereof). Cygwin does not provide these. It should be reported upstream. Actually we have a trac ticket and that has been reported upstream: https://trac.sagemath.org/ticket/21690 On

Re: [sage-devel] Problem building GSL in cygwin64

As suggested I did the following: cd sage export SAGE_ATLAS_ARCH=base ./configure --with-blas=atlas make Go the following error: Error building Sage. The following package(s) may have failed to build (not necessarily during this run of 'make all'): * package: libfplll-5.0.3rc0 log

Why is the constant coefficient of the resultant enough to determine if the resultant has a given root? On Wednesday, 25 January 2017 08:09:31 UTC+1, Ralf Stephan wrote: > > Thanks Dima. It turns out as absolutely essential for the implementation > of Gosper's algorithm. I can now get WZ

[sage-devel] Re: Bug report: Incorrect json representation for graphics.

Discussion should now rather take place on the ticket page. Please ask for a trac account (this may take some time). I am not sure that this json is sent to jmol at all. We also have a jmol_repr method. But maybe it is used in some three.js interfaces or in sagemathcloud. Now looking at other

[sage-devel] Re: Bug report: Incorrect json representation for graphics.

Thanks for taking care of this. I see that you fixed the doctests too. However, doctests will also fail in the description of `json_repr` in file `base.pyx`, in a few instances. More importantly, you absolutely should verify that you can send the corrected json to jmol and have it work. El

Markdown below: Bug report: Incorrect json representation for graphics. ## Extended description The json representation for graphics (which I believe is intended for Jmol), is **not** correct json. To wit: sage: G = cube((0,0,0),1) sage: obj_list =
