[gentoo-user] how do I remove evolution from gnome?

[Ric de France]

Hi list(s),

I was looking through the dynamic USE flag page (
http://www.gentoo.org/dyn/use-index.xml ), and noticed there were some
flags that brought in evolution support... but after realising I don't
used evolution (as I am happy with thunderbird), I was wondering how
to remove evolution from gnome once and for all...

The solution would be something along the lines of:

# USE="-something" emerge -DNuva world
# emerge -P something_else

That was I was hoping that if I was going to -DNuva on world again, it
would not brought in again... I know I would be editing /etc/make.conf
to make it more permanent than just doing it before the emerge world
command...

It's just that I'm having a hard time from figuring out which USE
flags (if any) to remove to get rid of evolution...

Any suggestions?

TIA,

...Ric

You can't so it with USE flags as evolution is a hard dependency on 
gnome-base/gnome:

RDEPEND="!gnome-base/gnome-core

	[snip irrelevant depends]

        >=gnome-extra/gtkhtml-3.12.2
        >=mail-client/evolution-2.8.2.1
        >=gnome-extra/evolution-data-server-1.8.2
        >=gnome-extra/evolution-webcal-2.8.0


So, if you emerged gnome, you's-a-gonna get evolution. Instead, you 
should unmerge gnome (it's just a meta package), then merge 
gnome-light. This is a minimal set of packages that gnome must have to 
work at all.

Then run emerge -pv --depclean to see what portage wants to remove. To 
prevent this, you must select the packages you want to keep from that 
list and explicitly put them into world with

emerge -avn <list of packages>

Then rerun emerge -pv --depclean again, and if you are happy losing 
what's in that list, let it run without -p

I put evolution in /etc/portage/profile/package.provided.

Then portage assumes, that it is installed ba hand and therefor it's not
installed installed automatically.

Unfortunatly, you still have to install eveolution-data-server and
evolution-webcal, because it's a hard-dependency of some other
gnome-package.

I thought an -eds USE flag will keep evolution-data-server 
from being installed?

No. I think you misunderstand the purpose of USE flags. They do not 
dictate what will be installed or not installed (although sometimes 
that happens as a side effect). USE flags dictate what FEATURES will be 
enabled in package that recognises the flags.

evolution-data-server does not make use of the eds flag (why would it? 
It doesn't need to support itself....). But openoffice.org does have 
such a flag. If you 'USE=eds emerge openoffice.org'  then OOo will be 
built with support for evolution-data-server. This is unlikely to 
compile successfully without evolution-data-server actually on the 
system, so the OOo ebuild contains this line

COMMON_DEPEND=
	[snip stuff]
 eds? ( >=gnome-extra/evolution-data-server-1.2 )

Which will pull in evolution-data-server and build before OOo. Note that 
this is a side-effect of enabling the USE flag. If you now remove eds 
from USE and rebuild OOo, it will be rebuilt without that support. 
However, the evolution-data-server package will remain on the system 
until you remove it explicitly with 'emerge -C' or implicitly 
with 'emerge --depclean' (--depclean will only remove it if it's not in 
your world)

There is a gnome-package, that doesn't compile without
evolution-data-server (I forgot the name, unfortunatly).
So evolution-data-server must to be installed.

Anyway: with the eds-useflag, you can ONLY disable the build of
evolution-data-server-related features of certain packages.
Even if you disable it, there may be packages, that don't recognize the
use-flag and have a hard dependency on evolution-data-server.

These packages need evolution-data-server for being compiled. There is
no way around this! The gentoo-guys can do nothing about it.

You could use gnome-base/gnome-light, which is basically (quote from the
ebuild):
"#  This is a wrapper for the 'light' Gnome2 desktop,
#  This should only consist of the bare minimum of libs/apps needed
#  It is basicly the gnome-base/gnome without all extra apps"

It does not depend on evolution, but some other program you might wanna
install later might.
