build ok but fails to start

[Frédéric Chapoton]

Hello,

something bad seems to happen when touching pyx files. Sage build ok but fails to start, unless I recompile with "make sagelib-clean & make build"

I got the following message at startup, see below. Any idea about the issue ?

From the error I'd say that the file got recompiled at "top level" rather than as part of "sage.misc" and the shared library in question got overwritten.

"make build"

alone does not work?

[Matthias Koeppe]

Indeed, and the command that did it is displayed in https://github.com/sagemath/sage/pull/38542

[Frédéric Chapoton]

so you mean this is caused by me playing with "cython -3 -a", right ?

How can I force the correct re-build now ?

[Matthias Koeppe]

Yes. "make sagelib-clean" fixes it.
