> gdb-cross-canadian was linking with static version of libpython
> and looking for build host python when run. This could be mismatch
> between python-nativesdk and build host provided python. So we
> make it consistent to always use python-nativesdk
>=20
> Instead of adding bunch of -L we add -rpath and -rpath-link
> so that gdb finds all needed libraries in SDK and does not
> reach out into host
>=20
> This should fix yocto PR# 2077 as well.
