Hi, dmraid-1.0.0.rc13 started linking with zlib for crc32(), this is used to support "SNIA DDF1 v1.0 metadata". Debian has libdevmapper in /lib and zlib in /usr/lib, so this makes the dynamic dmraid binary we're currently shipping unusable until your /usr is mounted. I see the RPM packages are shipping a dmraid.static alternative, but they seem to require /usr by default as well. It would be nice to avoid this dependency; solutions we have discussed for Debian in <http://bugs.debian.org/396762> were: 1) copy crc32 from zlib 2) implement crc32 3) link statically with zlib (and only zlib) crc32() seems trivial to implement in C, here's a sample implementation with some optimizations (you might want to chop off the optims since metadata is probably not crc-ed a lot of times): <http://www.w3.org/TR/PNG/#D-CRCAppendix> I attach the patch to force linking statically with zlib, by Steve Langasek, but beware not to add any lib after zlib in the Makefile or these would *always* be linked dynamically obviously. You might want to drop the zlib dep because of the +12KB it causes (crc32() is IMO smaller). Bye, -- Loïc Minier <lool@xxxxxxxx>
