Ah sorry my script must have been wrong. I did another scan. # Number of ELFs in packages depending on libgsl2 $ wc -l elfs 2315 elfs # Number of ELFs linking against libgsl.so.19 $ for i in $(cat elfs); do readelf --dynamic $i | grep -q libgsl.so.19 && echo $i; done | wc -l 704 # Number of ELFs linking against libgslcblas.so.0 $ for i in $(cat elfs); do readelf --dynamic $i | grep -q libgslcblas.so.0 && echo $i; done | wc -l 681 I guess -Wl,as-needed accounts for most of the difference.
