(Old) Cygwin prebuilt sage binaries for cygwin are here: http://sage.math.washington.edu/home/wstein/binaries/cygwin/ 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, * and patch (at least on Windows 7 building Sage's spkg patch fails, see #11232) * Possibly libiconv on Windows 7? * Apparently openssl on Windows 7 in order to build libgpg-error * And, as a reminder, dont' forget fortran * And make sure you download all gcc and g++ so the versions match * On a very minimal install, you may need to put in gcc and make and m4 and perl... * ssh and scp don't hurt, either * and nano or vim or something to edit files with == Build Tickets == * #6743: An old metaticket for exactly this, which now points here === Win 7 only === * #11245: on Win7 tar does not unpack cddlib and networkx spkg's right. See the ticket for a workaround. * #11232: patch spkg should not be installed, use Cygwin's (needs review) * #11550: Singular does not build (see also the older #10235, which may or may not still be valid) * Issue with Python 2.6.4 building. Relevant comments: * Comment 0 - Original report, from March 2010, at [http://groups.google.com/group/sage-windows/browse_thread/thread/88499b995a22ecc1] * Comment 1 - I had no problems with that thus far in Vista Premium 32-bit - Alec Mihailovs * Comment 2 - 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 * Comment 3 (from somebody) "obsolete, as Cygwin now has Python 2.6.5 as the standard" - true, but apparently still a problem for us * Comment 4 - Python spkg builds fine on XP - kcrisman * Comment 5 - Tried this fix on Win7 after it failed on the first extension, but it failed in the next extension after that. Rebasing everything in $SAGE_ROOT seemed to fix that, however, so this remains an open issue. === Win XP only or both === * #11246: flint-1.5.0.p5 extraneous #includes break typedef ulong (needs review) * #11119: ECL 11.1.1 fails on Cygwin (patches fixing the issues given on the ticket) * #10240: pari-2.4.3.svn-12577.p9 incorrectly checks for the shared library on Cygwin (should be fixed by #11130) * #11494: libblas.dll.a is not copied to $SAGE_LOCAL/lib when ATLAS is "installed" (breaks linbox) (should be fixed by #10226) * #11504: Tachyon fails to build due to same failure that was fixed in #7335. * #11547: The following files need to be copied "libcliquer.dll -> libcliquer.so", "libflint.dll -> libflint.so", "libntl.dll.a -> libntl.dll" * #11497: Twisted sometimes doesn't build * #11499: sage/rings/factorint needs gmp as a dependency * Maxima * #11502: Maxima fails to build on Cygwin on XP * Though Maxima did build (precisely) once out of a number of tries on XP lately * #11260: ECL-11.1.1 fails to compile maxima on WIndows 7 / Cygwin 1.7.9 (really stuck here :-( ) * #8269: Maxima doesn't build on XP (but apparently this should be closed?) == Getting Sage to start == * Pari segfault on startup (see [http://groups.google.com/group/sage-devel/browse_thread/thread/3fb9d33037670185/68e765f1ea5afb2d?#68e765f1ea5afb2d this sage-devel thread] * This seems to be related to defining Pynac's I, perhaps, but ends with a signal error, apparently. == Doctest Tickets == * #9162 -- pynac.pyx use double precision special functions instead of long double (REVISITED) * #9165 -- lcalc does not work for elliptic curves 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 == Closed == * #9845: lcalc doesn't build on cygwin due to missing time.h include * #9776: Cygwin: GLPK extension module needs to be more explicit in its linking (positive review) * #9146: cygwin: gd doesn't correctly link in libpng with sage-4.4.3. * #8257: gd needs a better version of expr * #7319: gdmodule fails * #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) * #8192: !PolyBoRi needs png12 and z to build on Cygwin. * #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. * #7337: !PolyBoRi fails to build on cygwin * 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 * #8848, #8847, #8846, #8845, #8844, #8843 * #9067: boehm_gc (still) fails to build on Cygwin * #9166 -- sympow does not work on cygwin (This should be fixed by the patches made for Solaris x86 - see #9703) * #9154: BoehmGC again! * #10247: Sage 4.6 has PARI problems on Cygwin * #11167: Sage 4.7.alpha3 library doesn't build under Cygwin * #9163 -- output of a subtle test in expect.py differs slightly on cygwin == how to mark CYGWIN-specific parts in code == gcc on CYGWIN defines a variable {{{__CYGWIN__}}}. So you can use it to #if(n)def stuff.
