I have a Keil MDK project which outputs a library mc_comms.lib. I have another Keil project which uses this library and don't have any issues. My customer is using STM Cube and can't build the same test project with the same library.

Do you know what is my problem? How can I resolve it?
Thanks.
I added the linker script file used by the Cube project to Keil linker options.. Here is my build output:
