Description (last modified by )
Cygchecking the package shows that it looks for an inexistent libLfunction.so. Indeed, this file is moved to libLfunction.dll on Cygwin to let Sage build. But at runtime, it is the original .so file which is looked for (surely some DT_SONAME equivalent). Letting libLfunction.so in place and symlinking it from libLfunction.dll seems more functional.
A better solution would to tell lcalc to build directly a .dll file on Cygwin (and .dylib on Mac OS X, etc.). Updated spkg doing so at http://perso.telecom-paristech.fr/~flori/sage/lcalc-1.23.p11.spkg or http://www.infres.enst.fr/~flori/sage/lcalc-1.23.p11.spkg
Apply trac_13351.patch

I think its the last ticket needed to correctly build Sage and get a working version except for a few doctests. It would be great to have it for 5.8, nobody wants to have a look?

I'm sorry, Jean-Pierre - I agree, but I simply have had no time at work to deal with my XP box (esp. since the 32-bit issue apparently is preventing proper rebasing, as discussed somewhere). I hope to try again over spring break in a couple weeks.

I'm away at a conference, and don't have access to a WIndows machine, until Sunday. And then I'll have jetlag :-) So it has to wait for few days, sorry.

note that

works.

Did you install the patch to the Sage library and rebuilt it as well?
note that
sage: import sage.libs.lcalcworks.
That's expected, this file is not touched and does not depend on the spkg.

yes, I certainly applied trac_13351.patch and ran sage -b. (on 5.7.beta2, but I guess it should not matter).

what happened is that the Python extension didn't get rebuilt, as the patch didn't touch the corresponding pyx file! So I touched this file, and now everything works. Positive review.

Update lcalc spkg, modifying lot of the Makefile (that we already modify and which is not that nice) available at http://perso.telecom-paristech.fr/~flori/sage/lcalc-1.23.p11.spkg
This will also need a Sage library patch.
