uVision to ARM DEVELOPMENT STUDIO import (using FUSA )

We are using the FUSA and keil uVison IDE for the project and wanting to test the new Android Development Studio IDE.

But import didn't go as smoothly.Getting multiple  'Error: L6218E: Undefined symbol' errors.

Partial list:

Error: L6218E: Undefined symbol _setup_stack_from_initial_sp (referred from system_stm32wbxx.o).
Error: L6218E: Undefined symbol __scatterload_rt2 (referred from system_stm32wbxx.o).
Error: L6218E: Undefined symbol __cpp_initialize__aeabi_ (referred from system_stm32wbxx.o).
Error: L6218E: Undefined symbol main (referred from system_stm32wbxx.o).

..

Have I missed something in the import procedure?
