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.
You also might want to post in the GNU Toolchain forum. For example, this post sets up a .ld file that defines a _ebss - one of the symbols you are missing.
