The problem you're solving is specific to cross-canadian.bbclass which changes libdir to include a suffix. Please append your two entries to this variable within cross-canadian.bbclass and then this makes a lot more sense! If you don't it will lead to strange RPATHs in parts of the system. Technically this change shouldn't be necessary since we'd use our own dynamic loader within the SDK and it knows about the paths apart from the one with the suffix. We likely could therefore remove some of this but now isn't the time for that! If you used a cross-ldd for our SDK toolchain, you'd should see something different to the above. Cheers, Richard
