Compilation problem with Python < 2.6 and db >= 4.7

[kiorky]

Is there a way to make the bsddb module compile against db>=4.7 for python < 2.6
(2.4.6, 2.5.4)? A patch ? A tip ?

For the moment, i have a known failure as:
gcc -pthread -fno-strict-aliasing -DNDEBUG

I looked for the one inside python >= 2.6 and it seems to have changed a lot so
backporting it seems difficult and maybe break the old API.

I didn't find something on it.

I don't think so, no.

If you don't want to use pybsddb either, for fear of incompatible API,
your only choice is to port _bsddb.c to the newer db versions. BSDDB
is in the tradition of both breaking the data format and the API
frequently, so we (python-dev) have given up on it.

Yup, i understand.
I will be lazy and fall back as all packaging systems do, and keep in the
minitage packages tree both db versions.
Thanks for confirmation.
