Cannot build with arm-none-eabi-gcc v11 or higher #493

Open microbit-carlos opened 10 months ago

microbit-carlos commented 10 months ago

There are build issues with v11.3.1 (Arm GNU Toolchain 11.3.Rel1) and v12.3.1 (Arm GNU Toolchain 12.3.Rel1 (Build arm-12.35)). Works with v10.3.1 (GNU Arm Embedded Toolchain 10.3-2021.10).

The linker basically fails to find implementations for _getpid and _kill.

With gcc v11:

$ yotta build

  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

And with gcc v12 we get the same linking error:
