Here is a list (in-progress) of the things needs to get Sage to build (and pass most tests) on Cygwin:

Cygwin Prerequisites

These Cygwin packages need to be installed in order for the Sage build to complete.

  • file, liblapack, liblapack0, liblapack-devel

Doctest Tickets

  • #9162 -- pynac.pyx use double precision special functions instead of long double (REVISITED)
  • #9163 -- output of a subtle test in expect.py differs slightly on cygwin
  • #9165 -- lcalc does not work for elliptic curves on cygwin
  • #9166 -- sympow does not work on cygwin
  • #9167 -- importing sage.libs.ecl yields a "no such process" error
  • #9168 -- ratpoints does not work correctly
  • #9169 -- a cachefunc.py doctest hangs seemingly forever
  • #9170 -- get_memory_usage isn't implemented, e.g., because there's no top
  • #9171 -- some test failures in sagedoc.py
  • #9172 -- numerical noise in sage/rings/integer.pyx
  • #9173 -- BSD.py tests behave differently on cygwin, so need to be written to reflect that
  • #9174 -- robert miller's 2-descent is completely broken on cygwin
  • #9176 -- various heegner_index errors involving interval arithmetic on cygwin

Build Tickets

  • #9154: BoehmGC again! (needs review)
  • #9775: lcalc should make a .dll file on Cygwin instead of .so file (needs review)
  • #9776: Cygwin: GLPK extension module needs to be more explicit in its linking (needs review)

  • #9146: cygwin: gd doesn't correctly link in libpng with sage-4.4.3.
  • #8257: gd needs a better version of expr
  • #7321: numpy fails to build on cygwin due to not using the correct fortran compiler
  • #8780: Add cephes spkg for Cygwin (provides complex.h amongst other things)
  • #8782: pari does not work under Cygwin
  • #8907: Python should be build with enable-shared
  • #9050: libntl.dll should be libntl.dll.a
  • #8542 / #8903: Pynac needs to use a function pointer table.

  • libflint.dll needs to be libflint.so, or polynomial_integer_dense_flint.pyx needs to know to use the .dll (maybe not a real issue, let's wait an see on this one).
  • #8642: port detection for the notebook does not work in Cygwin
  • #8855: sage-env needs to be updated for Cygwin
  • #8853: fix M_PI_4 in complex_double on Cygwin
  • #8852: minor doctest fix in fast_eval.pyx for Cygwin
  • #8850: Cython should link against BLAS instead of ATLAS on Cygwin
  • #8849: the palp interface throws a (harmless?) OSError on Cygwin
  • #9067: boehm_gc (still) fails to build on Cygwin

Possible issue with Python 2.6

(I had no problems with that thus far in Vista Premium 32-bit -Alec Mihailovs)

(Alec - Win7 has a newer codebase, so this is not really a proof that we need not worry --- I think we really need to. Dmitrii)
