Maybe I miss something and I have not dove into all the details so I
could be totally wrong.  However, from my understanding, A is built
against the shared library C1, and B is built against the shared library
C2, and nothing says that C1 and C2 are compatible.  If you run A inside
B, then C2 is used for both A and B, and A fails because it expects C1
and finds instead C2.  I miss why it is considered as a bug.  Aside the
fact that A and C1 are system-wide so without any control on how it is
built.

From my understanding, it is a bug if A built against C2 run inside B
built too against C2 does not work; which correspond to:

      guix environment --pure --ad-hoc emacs evince
      emacs -q -f shell

    and type “evince”.

    Then I do not have any error when I open the print dialog; but I have no
    setup for CUPS on my machine though.

And it appears to me also a bug if:

  guix environment --pure --ad-hoc emacs-no-x
  emacs -q -f shell

and type “/usr/bin/evince” where the print dialog fails.  On my machine,
it is not the case; but I have no setup for CUPS on my machine though.

Otherwise, from my point of view, failure should happen and I miss why
it should be considered as a bug, but as I said, I should probably miss
something and be wrong.

On foreign distro or Guix System?


All the best,
