# Generally, we (and cross in general) need the same things that native needs,
# so it might make sense to take it's mapping. For now, though, we just mention

# In the cross compilation case, rustc doesn't seem to get the rpath quite

# include the '../../lib' (ie: relative path from cross_bindir to normal
# libdir. As a result, we end up not being able to properly reference files in normal ${libdir}.
# Most of the time this happens to work fine as the systems libraries are
# subsituted, but sometimes a host system will lack a library, or the right
# version of a library (libtinfo was how I noticed this).

# FIXME: this should really be fixed in rust itself.
# FIXME: using hard-coded relative paths is wrong, we should ask bitbake for
# the relative path between 2 of it's vars.
