To clarify, what is the bug that you are reporting?

Are you reporting that `guix package -i gtkmm <at> 3` did not work?

Or are you reporting that the hint mentions the wrong package? (I think
it should talk about libsigc++, not gtkmm)

Okay. Is the hint unclear?

The hint is saying that you are trying to install a package that would
conflict with packages that are already installed.

Specifically, you already have installed a package that "propagates"
libsigc++. That means that the package installs libsigc++ alongside
itself.

Now, you are trying to install another package that propagates a
different version of libsigc++. They cannot both be installed in the
same profile.

Guix includes two versions of libsigc++, but you cannot install both of
them in the same generation of a profile.

In general, I think that installing gtkmm is unusual. Gtkmm seems like
something that is used by other programs internally rather than directly
by users. What are you trying to accomplish by installing gtkmm?

I'm very interesting in your experience with this situation, because
other Guix users have expressed confusion with it. I'm planning to
improve the documentation about these "conflicting entries" errors.

  I'm reporting that it did not work.

   Not to me it's not.  You however don't seem to get it...

   No it isn't.  It is saying that the package definitions for gtkmm and its dependencies are inconsistent.

    I haven't.  Please try to get your head around this.

    I am trying to install a package, defined right there in the GUIX repo, which propagates two different versions of
libsigc++.  Please try to get your head around this.

    I agree with you here.

    My software builds against it.

    I would suggest asking someone else to write the documentation; you don't seem to understand it well enough.

I take back everything that I said in the previous message; I sent it quicker than I should have, I'm sorry.

I still don't think the documentation needs changing, just those error messages need to be made clearer.

This issue can be closed now, thank you.

I see. That should be fixed.

It's true that my earlier reply was kind of dense, but you didn't put
any effort into your initial report, and thus you did not communicate
the problem effectively. You have to understand that we triage bug
reports from people with all levels of skill and experience.
