Description (last modified by )
lcalc works fine for the zeta function on cygwin, evidently:
sage: time lcalc.zeros(4) CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s Wall time: 0.19 s [14.1347251, 21.0220396, 25.0108576, 30.4248761]
However, it doesn't work for computing with elliptic curves:

Note gcc gives many compiler warnings and SunStudio refuses to compile the source code. These matters are probably not entirely unrelated.

The lfunctions/ directory appears to pass doctests on a recent build of mine on XP.
comment:4 Changed 8 years ago by
plot/line.py also passes tests (though many others do not in plot/, perhaps due to "I" currently not working).
comment:5 Changed 8 years ago by
But there is a segfault on the very first example above. Strange that the tests pass.

- Status changed from new to needs_review
These both pass and work "by hand" on XP now. I do get warnings about the new stack size, which keeps going down from 1 MB to .981, .957, .955 with these commands, but they do work (as does the one in line.py) so I would suggest a different ticket for handling the stack on Cygwin.
JP, can you confirm these pass on Win 7? Then we should be set.

- Status changed from needs_review to positive_review
For info, this file passes its tests on my Windows 7 install (without #13351).
So let's close this one.
