It seems that Sage 5.7.beta0 is almost there in sense of building and
running Sage on a recent Cygwin (on a 64-bit Windows 7 system).
I've built it with very minimal hacks (a couple of trac tickets which
didn't make it into this release yet) and rebasing twice during the
installation.
Here is the list, with brief/incomplete diagnosis/symptoms,
of failed tests during "make test". (full log here:
http://boxen.math.washington.edu/home/dima/tmp/cygwin_sage-5.7.beta0....)
Out of 21 failed tests:
3 are numerical noise.
2 are due to segfaults in the external program "nef"
4 are due to not implemented memory usage function
5 are partly due to a problem converting Python long to C long
(probably 32/64-bit issue); in Singular and in sparse matrix
2 are due an interpolation error in gsl
2 are due to a Singular problem, like
"Exception KeyError: (The ring pointer -0x1bbd6b8,) "
the rest are things like inline fortran and cython problems, probably
not hard to fix.
