Hi all,
I naively decided to update some of my fink packages after installing
Tiger 10.4.1 on my Powerbook. I updated the Geant4 package, which in
turn updated the CLHEP package. The problem is that all my Geant4 code
has been written using the previous versions of Geant4 and CLHEP, and
more importantly - the previous version of gcc (version 3.3).
If I try to compile my code with gcc 4.0 I get a lot of compile errors
and mising files, etc. My code consists of around 2000 files and I
don't really have the time to migrate to gcc 4 yet (and besides that,
none of my users have this version yet), so I used gcc_select to
revert back to 3.3. The problem is that I don't think the newer
versions of CLHEP and Geant4 like working with this version of gcc. So
I again get lots of compile errors - most of which are minor
convention/standard changes.
So my question is: can I undo the package updates? I want to go BACK
to the versions of CLHEP and Geant4 that I originally had with
Panther! Is this possible? Or is it the case that once you upgrade a
package there is no return??
Kind Regards,
John Carter
Sans an operating system update, you could do this relatively easily;
fink install <package-version-revision>
e.g "fink install foo-1.2.3-4"
However, with an OS update life is more difficult--since the 10.3
package descriptions aren't accessible to you anymore.
If you still have the .deb files for the older versions (i.e. you
didn't remove your 10.3 tree yet) you can manually install the older
binaries:
sudo dpkg -i <filename>
They _may_ run on Tiger, but no guarantees there. You may want to
contact the package maintainer, too.
