error[E0463]: can't find crate for core #164
Description
hi, there,
i tried to compile 01_wait_forever sample but get an error log like below:
yan@ubuntu:~/Desktop/rust-raspberrypi-OS-tutorials/01_wait_forever$ sudo make qemu
Compiling kernel ELF - rpi3
Compiling mingo v0.1.0 (/home/yan/Desktop/rust-raspberrypi-OS-tutorials/01_wait_forever)
error[E0463]: can't find crate for `core`

= note: the `aarch64-unknown-none-softfloat` target may not be installed
= help: consider downloading the target with `rustup target add aarch64-unknown-none-softfloat`
For more information about this error, try `rustc --explain E0463`.
error: could not compile `mingo` due to previous error
make: *** [Makefile:121: target/aarch64-unknown-none-softfloat/release/kernel] Error 101
according to log note "consider downloading the target with rustup target add aarch64-unknown-none-softfloat",
but i think the mentioned compiler had been added on my environment:
yan@ubuntu:~/Desktop/rust-raspberrypi-OS-tutorials/01_wait_forever$ rustup show

so, may something in my environment setting was not right, but don't know how to figure this mess out.
please give some advice, thx.
