Ah, you did say cross compiling so . . . my instructions above were for native( on the BBB ).
Well since you forgot to mention which cross tools you're using . . . https://wiki.debian.org/Multiarch/HOWTO Also, Derrek Molloy has a video on youtube for setting up a cross toolchain for the beaglebone white, and possibly an early video for setting up a cross toolchain for the beaglebone black using the armel ABI. If you follow that video exactly, and use the armhf ABI instead, it should work perfectly fine. It did for me.
