[And it makes my response much simpler.] Yes, I understand *why* it is doing it. It just doesn't rhyme very well with the way I do things. Pulling in dependencies at install is something I expect (and can easily check in advance, thanks to the well thought-out Debian packaging system). Calling "apt-get install" (to my *main* system, not to the chroot!) from a seemingly unrelated command is something I... dislike (there were other things I disliked, too). So this was just a heads-up for others like me. I had a look into the mk-sbuild script and decided to purge ubuntu-dev-tools.

You can do everything that mk-sbuild does for you manually, but when you're setting up many different sbuild chroots, it makes things much easier. [And it makes my response much simpler.] The things that mk-sbuild installs are just sbuild, schroot, and debootstrap, and possibly lvm2 if you're using lvm chroots; I actually didn't notice that it even did that because I have all of them installed.

Re: GCC 7
I tried schroot in a different way, as described here: https://wiki.debian.org/Schroot As part of the process, you install a complete, fresh Buster with: debootstrap buster /srv/chroot/buster So this solution is like a container.

Re: GCC 7
Thank you, Don, for your advice! I tried schroot, and it's awesome! I followed the steps on: https://wiki.debian.org/Schroot I was able to build my code just as on Buster. The difference between schroot and chroot is that with schroot you have assess to the files outside the root directory of chroot (like /srv/chroot/buster), and I'm thinking specifically about the home directory.

Re: GCC 7
Georgi, thank you for you email. I gave it a try. On Stretch, GCC 8.1 compiled and installed cleanly. I put the path to the gcc binary (/usr/local/gcc-8.1.0/bin) in my PATH, and I compiled and ran my code without any other configuration. I expected some linking problems, but the binary dynamically links to the system libraries, and things are OK. Cool! Thanks again!
