The logic is still run, but the resulting binary in classic uses rpath and no

make the build process a lot slower. We will need to look into it, but not
short term.
OK -- thanks for the explanation. Completely understand the preference to
require explicit staging of packages over potentially fragile automation.
Anyway, I had a go at tweaking my snap package as defined here:
https://github.com/WebDrake/ldc2.snap/pull/1/files
https://github.com/WebDrake/ldc2.snap/blob/a437ec17d50bdd767febebf5b617d7d3a716716b/snapcraft.yaml
... to use `classic` confinement and staging packages necessary for linking.
I've posted the resulting `snapcraft.yaml` below. The major diff apart from the
`confinement` setting is the addition of these lines to the `ldc` part of the file:
stage-packages:
- libconfig++-dev
- libphobos2-ldc-dev
When I run `snapcraft build`, however, everything builds and links fine, but
_nothing_ gets staged (the `stage/` and `prime/` directories both remain empty).
I've tried the same thing while removing the `gcc`, `gcc-wrapper`, `libc6` and
`libc6-dev` parts, with the same result.
Any thoughts on what could be the problem here?
