Build fail

[DanielTao1109]

Hi,
I followed the steps in README.md to try build my chrome image.
Following the steps,

1. I repo sync the branch release-R75-12105.B from googlesource.
2. add this repository in chromiumos/src/overlays
3. run:
   (inside) export BOARD=amd64-generic_vmware
   (inside) setup_board --board=${BOARD}
   (inside) ./build_packages --board=${BOARD} --nousepkg

And met the error:
rust-1.34.0: * ERROR: dev-lang/rust-1.34.0::chromiumos failed (setup phase):
rust-1.34.0: * missing toolchain armv7a-cros-linux-gnueabihf
rust-1.34.0: *
rust-1.34.0: * Call stack:
rust-1.34.0: * ebuild.sh, line 124: Called pkg_setup
rust-1.34.0: * rust-1.34.0.ebuild, line 76: Called die
rust-1.34.0: * The specific snippet of code:
rust-1.34.0: * which "${tt}-clang" >/dev/null || die "missing toolchain ${tt}"
rust-1.34.0: *

Can you help to check is the steps workable?
And should I repo sync the release-R75-12105.B branch? (chromium_os-vm-vmware's branch name is r89 now)

Thank you!

if you are using the r89 branch of chromium_os-vm-vmware's overlay, yes you do need to have a matching repo, i.e. release-R89-13729.B.

You need to create a new repo folder and sync down the code for r89 and start over.
