Here is a hack I just threw together. It requires that you have a
local copy of the Contents file for your arch in /var/lib/dpkg.
#!/bin/sh
# findlibpkg: Find the libs that a executable depends on and what
# package they are in.
#
# usage: findlibpkg <full path of executable>
LIST=`ldd $1 | cut -d" " -f3`
for i in $LIST ; do
zgrep "`echo $i | sed -e 's/^\///'` " /var/lib/dpkg/Contents.gz
done
#end findlibpkg
As an example:
% findlibpkg /usr/bin/gs
usr/lib/libz.so.1 libs/zlib1g
usr/X11R6/lib/libXt.so.6 x11/xlib6g
usr/X11R6/lib/libXext.so.6 x11/xlib6g
usr/X11R6/lib/libX11.so.6 x11/xlib6g
usr/lib/libvga.so.1
libs/svgalib-dummyg1,libs/svgalibg1,libs/svgalib1-libggi1
usr/lib/libvgagl.so.1
libs/svgalib-dummyg1,libs/svgalibg1,libs/svgalib1-libggi1
lib/libpthread.so.0 base/libc6
usr/lib/libpthread.so.0 oldlibs/libpthread0
usr/lib/libpng.so.2 libs/libpng2
usr/lib/libpaper.so.1 libs/libpaperg
lib/libm.so.6 base/libc6
lib/libc.so.6 base/libc6
usr/X11R6/lib/libSM.so.6 x11/xlib6g
usr/X11R6/lib/libICE.so.6 x11/xlib6g
lib/ld-linux.so.2 base/libc6
I suppose this could be expanded to use the search engine at
http://www.debian.org/distrib/packages.html via a direct call to the
cgi script and lynx or something. That is for another day though.
Enjoy,
