[ros-users] Linking against 32-bit libs on 64-bit system

[Blaise Gassend]

You are going to have to build your whole app and all its libraries in 32-bits.

Last time we needed to do this, we set up a chrooted 32-bit
environment that we populated using debootstrap. If you come up with a
simpler way, let us know.
