Installing Python 3.3 on Cygwin

Question

I'm having trouble installing Python 3.3 on Cygwin. I've tried installing from source, but make returns:

gcc -Wno-unused-result -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes     -I. -IInclude -I./Include    -DPy_BUILD_CORE  -c ./Modules/signalmodule.c -o Modules/signalmodule.o
In file included from Include/Python.h:84:0,
                 from ./Modules/signalmodule.c:6:

     PyStructSequence_SET_ITEM(result, 6, PyLong_FromLong(si->si_band));
                                                            ^

Makefile:1501: recipe for target 'Modules/signalmodule.o' failed

Any thoughts?

Can you show the text before that? All it says is that some command failed, but we need to see the commands. — Ramchandra Apte, Sep 12 '13 at 16:01
Cygwin's Python packages include a number of patches; I suggest using the 3.2 patchset and `.cygport` as a basis for working on 3.3. — Yaakov, Sep 12 '13 at 16:30
@Yaakov, I'm not really sure what you're referring to or how to execute it. Could you elaborate? — David Y. Stephenson, Sep 12 '13 at 16:49
@DavidY.Stephenson Yaakov is referring to the standard way to add external python packages to cygwin. Go to http://cygwinports.org to see the basic information. — squeegee, Sep 20 '13 at 17:35
What is the motivation for using Cygwin? The official distribution for Windows is excellent. — pepr, Jan 02 '14 at 20:10
I find working in a Windows environment exceptionally cumbersome. While the Windows Python distribution is quite good, I would still have to work in Windows. Fortunately, I am no longer working with Cygwin. — David Y. Stephenson, Jan 03 '14 at 04:21

Building Python on Cygwin is not trivial -- I tried. However, the Python community on its bug tracker website is unusually friendly and gentle for a project its size and importance. If you find specific issues, open bugs and follow the discussion. Usually, they will accept tiny patches to fix Cygwin build issues.

This patch will solve your first problem about si->si_band. See related Python issue #21085.

This blog post (in German) is amazing. It will walk you through step-by-step how to build Python3.4 and fix all Cygwin issues.

Good luck. You will need it.
