It has been there since the boost package was added: commit f64a740f360439bbab6526b8a08588a57ea8fd52 Author: Yegor Yefremov Date: Thu Oct 13 12:39:12 2011 +0200 boost: New package added. Version 1.47 [Peter: Config.in tweaks] Signed-off-by: Allan W. Nielsen Signed-off-by: Yegor Yefremov Signed-off-by: Peter Korsgaard But I don't know enough about boost to know if it really is needed. I must say that libbz2 is probably not your biggest concern compared to the size of libstdc++ and the template heavy boost code: -rwxr-xr-x 1 peko peko 73K Jun 3 20:28 output/target/usr/lib/libbz2.so.1.0.6 -rwxr-xr-x 1 peko peko 624K 2013-06-03 19:42 output/target/usr/lib/libstdc++.so.6.0.16 Will> If I change the boost package it still manages to build all the Will> libraries so I can't work out which libraries need bzip2. Perhaps it used to be a dependency of something, and isn't anymore? We have relatively recently (February) bumped the boost version to 1.53.0.
