I gave some pointers on relibtoolizing to my sponsees after vorlon
called for improved library handling as mentioned in
<http://lists.debian.org/debian-devel-announce/2005/11/msg00016.html>.
Especially KDE applications seem to be prone to depend on a plethora
of packages they don't really need for functioning due to the admin/
subdir as shipped by kdevelop, so relibtoolizing can save a great deal
here.
For example let's take a look a keurocalc, a package I sponsored for
Claudio. This is the wdiff between before and after proper
relibtoolization:
| Depends: [-kdelibs4c2-] {+kdelibs4c2a+} (>= [-4:3.4.2-1), libart-2.0-2
| (>= 2.3.16), libaudio2,-] {+4:3.4.3-1),+} libc6 (>= 2.3.5-1),
| [-libfam0, libfontconfig1 (>= 2.3.0), libfreetype6 (>= 2.1.5-1),-]
| libgcc1 (>= [-1:4.0.1), libice6 | xlibs (>> 4.1.0), libidn11 (>=
| 0.5.18), libjpeg62, libpng12-0 (>= 1.2.8rel),-] {+1:4.0.2),+}
| libqt3-mt (>= 3:3.3.5), [-libsm6 | xlibs (>> 4.1.0),-] libstdc++6 (>=
| [-4.0.2), libx11-6 | xlibs (>> 4.1.0), libxcursor1 (>> 1.1.2),
| libxext6 | xlibs (>> 4.1.0), libxft2 (>> 2.1.1), libxi6 | xlibs (>>
| 4.1.0), libxinerama1, libxrandr2 | xlibs (>> 4.3.0), libxrender1 (>>
| 1:0.9.0-1), libxt6 | xlibs (>> 4.1.0), zlib1g (>= 1:1.2.1)-]
| {+4.0.2-4)+}
(well, ok, this also includes the g++ transition, but I guess you'll
get the point)
20 Depends were saved, including libfreetype6 which stood at the
beginning of Steve's mail, resulting in a fine and clean
| Depends: kdelibs4c2a (>= 4:3.4.3-1), libc6 (>= 2.3.5-1), libgcc1 (>=
| 1:4.0.2), libqt3-mt (>= 3:3.3.5), libstdc++6 (>= 4.0.2-4)
which actually is all that package really really needs. All the other
Depends were just unnecessarily pulled in.
Of course, maintainers shouldn't relibtoolize just for the sake of it,
but sometimes it's truly worth the effort.
HTH,
