Dear All,
I was writing some code for sage and ran into trouble. The code was
working just fine when it was a standalone function. Then I tried to
add it to a pyx file (sage/rings/fraction_field_element.pyx to be
precise) and ran into trouble. Somewhere in the code I would like to
use the command

Currently, when ATLAS builds in Sage, it uses this option to the configure
scrip, it used the option -t 0, which disables threading.
The comment in spkg-install-script says:
# -t 0: disable threading for now.
and we can see that actually happens.

I can confirm that in 4.4.4 ALL revisions (there were 11, including
some from '1 day ago') of a worksheet I am working on are identical to
the current revision, which they definitely should not be!
This isn't exactly the same as Stan's issue, but almost certainly
related. Stan, can you post which
Hi,
Newer sympy has a bundled copy of mpmath, what causes several
problems in my sagemath package. I was in vacation during most of

Thanks! I replied to this in at least a preliminary way. But he is
right that the easy-to-find documentation on many of the interfaces in
practical terms is pretty rudimentary.

there are many major Sage components that do not build natively on
Windows, e.g. GAP,
and where native ports are not on roadmaps of the corresponding
development teams.
Other platforms might have a better chance, e.g. GAP is very compiler-
tolerant (as there is no C++ there).

Only if the environment variable SAGE_CHECK is set to "yes". In other words, by
default spkg-check does not run.
