Some further details:

  • issue 9665 is still opened (and as it is back from 2010 and was not modified since, I doubt it will be closed any time soon unless one of us takes action);
  • issue 14337 has been merged, but unfortunately after the Python 2.7.3 release;
  • issue 14338 has been closed as invalid and marked as a Cygwin, rather than Python, bug, why not... but what's sure is that it prevents to build Python on Cygwin.

The patche we need from 9665 modifies (the other patch is just issue 14337). In order to take it into account in the configure script, I ran "autoreconf -i" which also modified the configure script in several other places, but in a seemingly harmless way. It is mainly because I used a newer version of autotools than the one originally used for the Python 2.7.3 release, and autotools decided inbetween to prefix some variables names with "ac_". A somehow less invasive solution would be to directly patch the configure script, but I'm less inclined to do so than properly patching

The updated spkg is available at:

It builds correctly on Ubuntu 12.04 64 bits and is currently building on my Cygwin 1.7.16 on Windows 7 64 bits (it failed a first time but because of memory exhaustion which I often get while using Cygwin or MinGW).

I've search trac for a more recent spkg than the 2.7.3.p0 but did not find anything. If I missed some tickets including such an spkg, please let me know or directly rebase the patches proposed here.
