Yes, "python2" is installed as optional package and this is simply running tests for that optional package. There aren't any such tests, but the test framework doesn't a priori know that. "python3" is not optional, therefore it's not listed in the --optional options. I agree that it's confusing, but it's not a bug. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

Possibly somewhat related (sorry if not): after building Sage for Python 3, running `sage -t` lets the doctesting framework decide what to set `optional` to, and apparently it uses "python2" rather than "python3"; is this the desired behaviour? $ ./sage --python --version Python 3.7.3 $ ./sage -t --all -p 2 Running doctests with ID 2019-08-29-17-56-03-a7156513.

Hello Somebody (else) should make sure that every single remaining piece of python2 is removed from a python3 sage. In particular, we should not build python2 at all.

Re: [sage-devel] Re: error building barvinok (sage 8.9.beta8 + system NTL)
Thanks for all of the thoughtful replies. I don't have time to rewrite the config script any time soon. According to the libtool documentation, it is supposed to be usable without relying on automake. NTL's config script allows you to override the default libtool with a system libtool, so that seems like the simplest way to deal with this for now. If I rewrite any of NTL's config scripts, it will likely be to move it over to cmake.

Re: [sage-devel] Wrong python in Sage shell?
It is sort of normal. [PEP0394] used to say that python should be an alias for python2. But now it says that it should either be python2 or python3. Sage just follows the logic that was in place.

is this python2 from your OS, or from Sage's installation?

On Arch we are building ntl using system's libtool.
