Hi Alex, Well, I have one question first before deciding the right way to proceed. Are all the objects you're creating the same general shape as the ones in the test.sobj you posted -- collections of polynomials over rational function fields in one variable over finite fields? If so, then we have two options; if not, we probably only have option (2).
(1) We can patch 3.2.3, so you can load the objects in 3.2.3. I'll then write a function that will take the objects, recreate corresponding objects in 3.2.3, coerce the old ones over, and re-save them. This isn't so bad, but it depends on me knowing exactly what kind of objects you've got. It's slightly more error-prone, I think. (2) We build and patch 3.1.1, and you just load and save each object. Then they should load fine in 3.2.3. Which seems better to you? (I think (2) is slightly easier for me, but nominally more work for you -- you have to build 3.1.1 on your laptop.) -cc On Mon, Mar 2, 2009 at 10:32 AM, Alex Lara <lrodr...@gmail.com> wrote: > > Hey Craig, > > I have 3.2.3 in my laptop, but I use the machines of the University > (which have 3.1.1) to do computations that take long time. > > ---Alex > > On 2 mar, 11:19, Craig Citro <craigci...@gmail.com> wrote: >> Ah, does this mean you have a running copy of 3.1.1 still?
