Cannot install pysqlite on Cygwin

[Tilman Kispersky]

I am trying to install sqlite for use with python on cygwin. I have
installed the sqlite packages from cygwin (that is libsqlite3-devel
and libsqlite3_0). When attempting to easy_install pysqlite I get:

It seems to me this is due to some missing library (undefined
reference...) but I have no idea what these missing files might be.
I've tried installing everything that made any reference to sqlite
form the cygwin interface. Does anyone know how I might get a working
install of sqlite for python on cygwin?

It might be that Cygwin's SQLite doesn't support loading extensions.

Either:

Rebuild SQLite from source on Cygwin and be sure to include

--enable-load-extension when calling ./configure.

Or hack the pysqlite sources and remove these lines in src/connection.c:

#if SQLITE_VERSION_NUMBER >= 3003008
#define HAVE_LOAD_EXTENSION
#endif

I'm very interested how you can fix the problem.

I believe it's a glitch in the 2.5.1 distribution current on Cygwin - I
had to install the _sqlite DLL separately to get it to work, but no
recompilation was necessary AFAICR.

Chui Tey detailed the necessary steps in his blog post "Cygwin Python
and sqlite3", but sadly it got lost and he hasn't replenished it, so you
will have to stab around to see if there's a cached copy anywhere.

Well, I haven't managed to solve the problem.

I tried following these instructions but get the same error:
http://initd.org/pub/software/pysqlite/doc/install-source-win32.html

And I also tried downloading the dll from sqlite.org and putting it on
my path.

Since someone asked how I ended up solving this problem:
I'm just going to work on my Linux box where its relatively straight
forward to install
this stuff with the package manager.

If someone does have instructions for making this work on windows I'd
be very curious. I was unable to find an archived version of the blog
post referenced above.

I also managed to get it to work by not using cygwin's python.
I suppose this is sort of the obvious solution.

Just download the windows installers for python, pysqlite.
You can still run the windows installed version of python from cygwin
(I prefer that over the 'cmd' terminal) by specifying
the executable you want to use explicity eg:
$ /cygdrive/c/Python25/python
