问题


I want to build samples/subsys/power/device_pm using clang6.0 so I do as follows:

  1. export ZEPHYR_TOOLCHAIN_VARIANT=llvm
  2. mkdir build and cd build
  3. cmake -DBOARD=reel_board ..
  4. make

Then, I got some errors:

Is there any suggestion? Thanks a lot!


回答1:


reel_board is ARM right?

ARM is not supported for Clang yet unfortunately.
