Juanjo, it sounds like you want to read http://www.sagemath.org/doc/developer/producing_spkgs.html
and http://www.sagemath.org/doc/developer/patching_spkgs.html Because Sage may sometimes have custom patches to ECL that weren't in upstream at the time but are now, I don't know if it can be done 100% automatically. But what you *could* do is the following: Download the latest ECL spkg ecl-x.y.z.spkg Untar it Replace the src/ directory with the new source Rename the ecl-x.y.z directory to ecl-w.v.u Forget about anything else (you're not making a new spkg really, just testing this) sage -pkg ecl-w.v.u/ sage -f ecl-w.v.u.spkg sage -f maxima and see what happens. If you look at the SPKG.txt in the ECL in the current Sage alphas (available at http://trac.sagemath.org/sage_trac/ticket/11884) you will see that we'd like to eventually have the test suite (optionally) run as well. It shouldn't be too hard to make an spkg-check for this, I guess. However, I don't see that you'd be able to "just test ECL" inside of Sage, because of the very specific config and deleting of tons of stuff we don't use, and linking against Sage-specific things. I'd be happy to talk off-list about how to do some of this, though I am not exactly an expert so it wouldn't be super-efficient. We all learn on the job, though. > > Somebody has suggested me that there is a way to get ECL automatically > > built and tested on the platforms that Sage support.
