I need libpango as a dependency of librrd4 to generate
graphics from rrdtool for output on a (monitoring) web server.
Installing the current version of libpango1.0 would start introducing
X11 libraries on to the system which would be completely unnecessary
otherwise. I admit that I'm afraid to have a complete gnome system
within 2 years of package upgrades.
Either the description
four different font backends:
...
- Direct rendering of scalable fonts using the FreeType library
or the dependency from libx11-6 and libxrender1
(and libx11-6 depending on x11-common in turn) seems to be at least bloating
in some uses of the package.
If the X11 dependency of some packages is achieved only by letting them
depend
on libpango, would there be some other way? (yes, I guess that this is not a
package specific issue but rather a conceptual one).
Thanks for your report.
% ldd -r /usr/lib/librrd.so.4 | awk '{ print $1 }' librrd4
% ldd -r /usr/lib/libpangoxft-1.0.so.0 | awk '{ print $1 }' | grep -v -xFf
librrd4
libXft.so.2
So that's the only thing which you'd save if I were to split
libpangoxft out; given the ridiculously large size of the librrd4 dep
tree, I don't think it would be useful and am closing this bug.
Please reopen if necessary.
The problem from a user's (server admin's) point of view is,
that the package libpango1.0-0 itself depends from a lot of other packages,
which, in turn depend on a lot of other packages which would not be needed
otherwise.
I can't find out, it it would be possible to create a package
'libpango-mimimal' which would provide libpango without the bunch of features
all the other dependencies are providing.
% apt-cache depends libpango1.0-0
libpango1.0-0
Depends: libpango1.0-common
Depends: libc6
Depends: libcairo2
Depends: libdatrie0
Depends: libfontconfig1

Depends: libglib2.0-0
Depends: libthai0
Depends: libx11-6
Depends: libxft2
Depends: libxrender1
Depends: zlib1g
Conflicts: pango-libthai
and when I try to install libpango1.0-0 on a system without X11 libraries, I
would get:
% sudo apt-get install libpango1.0-0

Abort.
And this, although I already would not install recommended packages
automatically:
% apt-config dump|grep -i recommend
APT::Install-Recommends 0;
So I do not know a way out of this situation but I find it a bit annoying
having to pull such a lot of packages, among them a some which are only
necessary for ouput on displays (which is definitely not a server's task):
libdirectfb-1.0-0 libx11-6 libx11-data libxau6 libxcb-render-util0
libxcb-render0 libxcb-xlib0 libxcb1 libxdmcp6 libxrender1
