Cross install is not supported. As you have seen, certain tools are bootstrapped on the build host and used during the install process. You might be able to get away with nuking /usr/obj/usr/src/arm64.aarch64/tmp/legacy (or maybe tmp) and then running `make toolchain` to build native versions of those tools. -- Brooks --BOKacYhQ+x31HxR3 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJiZvP+AAoJEKzQXbSebgfAO2YH/AlpfPiw7YHHW9AwJS20cMKz J4cbCSEpx/g+tc22NhjOwpPFw0Mo4SrpXma1bHBHkPkGHcSCtXt4FcNJWgaxDeA/ rDkZqnR4GzPhnQk1allJp9Dnkaz2VITCyANv2h9M6VcA/kFcp9Xu3Q58XQo94zrr 9q33ckDWyKPRLAuxfTRCFYlkCLbqaSXqBolOUy/8GGHzJMCpMK5n9e2NiGJh1tjn 8geps7gZwGvhswR44b3B2K0mus8yPwQBBhBItunPErAWzCZ9RVkUsnRvLoMyeap6 sR/WtQuQayRqkKOt45V1IYinWvqD2DLrUlKvqjPBor05LYfV5YYwxr+N8HiqzIA= =/NVF -----END PGP SIGNATURE----- --BOKacYhQ+x31HxR3--
