Same problem, and same trace!

$ rustc --version
rustc 1.30.1

$ git --version
git version 2.19.1

$ python --version
Python 3.7.1

$ cmake --version
cmake version 3.12.4

This seems a problem with Termbox and not with Amp.
Did you saw #110 ? Your python needs to resolve to python 2.x. to be able to compile Termbox.

[wblondel]

Ok, thanks, now we know what is the problem.

I found a solution on the ArchWiki: https://wiki.archlinux.org/index.php/python#Python_2
Read from "Finally, you may not be able to control the script calls, but there is a way to trick the environment. "

I followed the instructions and it worked.

[jmacdonald]

Thanks for the assist, @pbgc! The termion branch, once merged, will fix this by removing termbox as a dependency. 🙂

[craftyguy]

This is because termbox includes an older version of waf which does not have Python 3.7 support...
nsf/termbox#117

IMHO, "just use python 2.7" seems like a terrible solution. (termbox builds with Python 3.6, for example)

[jmacdonald]

@craftyguy you can use Python 3.6! The trick is that Arch's python package points to 3.7, and there's no easy way to point to <= 3.6. I'll update its build script to bring in python2 as a build dependency and alias it during the build. Then it can be installed temporarily with makepkg -sri, at least until we've moved away from termbox and it's no longer a dependency at all. 🙂
