Hi,

what has to be done for upgrading from Python 2.4 to 2.5?

- How can I find out which packages (in addition to the core packages) have been
installed up to now
- Can I just copy /usr/local/lib/python2.4/site-packages to
/usr/local/lib/python2.5 ?

Many thanks for a hint,

Alas, no, this will only work for pure Python packages.

If any of your packages are "extensions" in compiled languages
(typically C or C++) then they need to be completely rebuilt, as the
interpreter API changes between releases.

Technically you should be able to copy the pure Python packages and
midules across, althought eh .pyc file format alos differs between
releases. However, the .pyc files will all be rebuilt automatically when
they are required.

Steve

Which OS?

Windows: control panel / software will list all python packages which
came with separate installers.

Linux: the package manager of your distribution should tell you what's
installed.

It's Linux.
Thanks, but I don't have a package manager. I'm working with Linux-From-Scratch.

I've started keeping the tarballs for all of the packages I install in a
single directory, along with a shell script to install each of them. It
makes upgrading much easier. I do this on both Linux and Windows.
