[gentoo-user] unison requires Mozilla, doesn't accept Firefox?

[gentoo-user] unison requires Mozilla, doesn't accept Firefox?

[Mark Knecht]

Hi,
   It seems I've ended up with copies of Mozilla on the two machines I
used to check out Unison. Apparently, at least the way I emerged it,
the ebuild doesn't have any flags to effect this.

   Anyone know how to get rid of Mozilla in this case? If not should I
file an ebuild request?

Thanks,
Mark

I don't have mozilla installed:

$ emerge -avt unison

These are the packages that I would merge, in reverse order:

Calculating dependencies ...done!
[ebuild  N    ] net-misc/unison-2.12.0  -debug +gtk +gtk2 -static -threads 821 kB

No. You should file a bug (if it really *is* a bug). But you'll need to be able 
to reproduce it first.

Found out some more:

You seem to have the 'gnome', 'mozilla' and 'gtk' or 'gtk2' useflag in your 
make.conf.

This is the relevant dependency tree (snipped out some stuff):

[ebuild  N    ] net-misc/unison-2.12.0  +gtk +gtk2
[ebuild  N    ]  dev-ml/lablgtk-2.4.0  +gnome
[ebuild  N    ]   gnome-base/gnome-panel-2.10.2
[ebuild  N    ]    gnome-extra/evolution-data-server-1.2.3  +mozilla
[ebuild  N    ]     www-client/mozilla-1.7.11

You advised portage to build unison, which needs lablgtk. lablgtk gets built 
with gnome-support, so it needs gnome-panel, which in turn needs 
evolution-data-server. And since you have the global useflag mozilla, this will 
pull mozilla in.

Right? (could also be some other combination of use-flags, you get the idea)

Is it possible that the one of the dependencies pulls in Mozilla? Try
emerge with the --tree option for more info.

Christoph,
   Hi, I think you're basically right but this is a case where the
real meaning of flags is important? My understanding of the 'mozilla'
flag was that it instructed apps to build in support for Mozilla and
not that it required Mozilla to get emerged.

   My real thought here is not that I really want 'mozilla' support in
Unison but if any app needs a browser that it should be happy with
Firefox instead of any other app.

   I could look at removing the global mozilla flag and using it only
on certain apps, but really I'm wondering why Unison didn't accept
Firefox as a browser and wondering if the ebuild for it, or more
likely evolution-data-server, could be improved in that area.

thanks,
Mark

I don't know what unison is, but in most cases you can't just swap out firefox 
for mozilla.

Firefox is a web browser.
Mozilla is a web browser (with email client, etc) plus a sofware development 
kit and relevant development libraries.

So even though you are asking "Why does it need mozilla? I have firefox, won't 
that do?", the answer (in the usual scenarios) is no, as they are very 
different packages and firefox does not provide a lot of stuff which mozilla does.

Hopefully in the future, mozilla will split out the SDK/libraries into a 
seperate package so that you don't have to install the mozilla 
webbrowser/emailer/etc.

For right now, the moznocompose, moznomail flags gets rid of the html
editor and emailer. There are some other ones if you

grep moz /usr/portage/profiles/use.local.desc

Daniel,
   Hi. You make a very valid and important point. Thanks.

   Beyond Mozilla splitting out portions of it's functionality it
seems to me that, as a pure user type, I have no way of determining
what a given flag is intending to do when emerge is run. If, for
instance, there was some query through emerge that told me something
about what feature a flag was enabling then in this case (possibly)
we'd see that Unison was depending on Mozilla's mail features, or
Mozilla's browser features, or Mozilla's SDK. If it told me it was SDK
then clearly I wouldn't expect Firefox to provide that. If it's a
browser feature then I think I'd be warranted in asking why it didn't
accept Firefox.

   Is this not reasonable?

Thanks,
Mark

Not completely. I was going to say, most of the time when one installs a
program, one has some idea of what it does, and thus could hazard a
guess as to what thus-and-so USE flag could be expected to enable.

But in order to say that, I would have to know what unison was, so I
looked it up:

 eix unison
* net-misc/unison
     Available versions:  2.9.1-r1 2.12.0 ~2.13.0

     Description:         Two-way cross-platform file synchronizer



... and thought I could see no reason why a file-synchronization program
would demand mozilla at all, so I emerge -pv'ed it:

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] dev-lang/ocaml-3.08.1  -latex +tcltk 2,002 kB

[ebuild  N    ] net-misc/unison-2.12.0  -debug +gtk +gtk2 -static
+threads 821 kB

... and I do have 'mozilla' in my USE flags-- why, I don't know,
actually, but I disable the flag for individual programs, as I don't
want Mozilla, and don't have it installed:

So I don't know what's dragging mozilla in for you-- except that
evolution data server, which I noticed in one of your previous posts,
which does require mozilla, and is enabled these days via the 'eds' USE
flag, which I have explicitly disabled.

But even eds doesn't seem to be dragged in via the unison emerge; I
certainly don't see any 'eds' USE flag on any of the dependencies.

Ultimately, I'm questioning whether unison is in fact the culprit
here.... you might want to disable the 'eds' USE flag for gnome-panel,
if that's the real bad guy here, as Christoph suggested.

It wouldn't help in this case, because Unison does not depend on Mozilla,
nor does it use the mozilla USE flag. You can get the sort of information
you need by reading the ebuild, USE flag settings normally alter
configure options.

Some way of getting this information in plain English would be nice, but
that would require it to be added to every ebuild individually.

Basically, as far as i can work out, mozilla is a dependency of something
that is a dependency of (add layers of recursion) unison IF gtk and
mozilla are in the use flags.  USE=mozilla doesn't directly affect
unison, it works on one of the packages down the recursion chain a bit.
(I think it is in fact EDS)

Thats just from a play I had, can't be bothered repeating it or whatever,
-v,  -a and -t  are there to prevent unwanted consequences of emerge.
