[gentoo-user] Too many X modules pulled in

[Fredrik Tolf]

Dear List,

I'm trying to install Gentoo on a headless machine. I want programs to
use the X libraries, so that I can SSH in from another machine and use X
over TCP, but I'm not too fond of installing the entire X package
(especially the X server) on it, since it won't ever be used.

However, I just tried to install a couple of program linking against GTK
(such avahi), and GTK, for some reason, tries to pull in lots of stuff
that I don't really want (among others, the X server). Looking in the
GTK ebuild, I found this:

RDEPEND="|| ( (
                        x11-libs/libXrender
                        x11-libs/libX11

I even emerged all those X11 dependencies myself, but even then, it
wants to emerge xorg-server. The first few lines of the output of
"emerge -tvp gtk+" look like this:

[ebuild  N    ] x11-libs/gtk+-2.8.19  USE="X jpeg -debug -doc -tiff
                                      -xinerama" 12,015 kB 
[ebuild  N    ]  x11-misc/shared-mime-info-0.17-r2  558 kB 
[ebuild  N    ]   dev-libs/libxml2-2.6.26  USE="ipv6 python readline
                                      -debug -doc -test" 3,338 kB

                                      -minimal -xprint" 8,716 kB 

I'm not an expert with portage, but the fact that xorg-server is
indented one space from gtk+ means that gtk+ depends on it directly,
doesn't it? If so, whence does that dependency come from (it's obviously
not on the DEPEND or RDEPEND variables)?

Please help me -- what should I do to make gtk+ only pull in the minimal
amount of deps?

Thanks for your time!

It's because it inherits the virtualx.eclass -- gtk+ requires an X
server (Xvfb) to build. What you can do is set USE="minimal -dmx -xorg
-xprint" in your package.use for xorg-server to minimize this. Also try
VIDEO_CARDS="" and INPUT_DEVICES="" in make.conf.

However, this only works well on xorg-server-1.1, so you will also need
to add it to package.keywords.

Thanks,
Donnie

I see... how troublesome. Well, I guess there's no choice, but would
anyone happen to know the reason why gtk+ requires Xvfb?

Actually, it seems that it doesn't require Xvfb, or any other X server,
after all. I just tried emerge gtk+ with USE=-X, and it works perfectly.
It didn't emerge any X server, and it works just fine with all the
programs I've tried so far.

Does that mean that the virtualx eclass is unnecessary, and that I
should file a bug report to have it removed?
