Integration feasibility for STM32

[DanielSSolid360]

Hi, I'm trying to integrate this library in my keil uVision project based on the STM32G070 but I'm encountering problems in doing it. I have made some changes (like defining BARE_METAL) to adapt it but I still find linker failures:

.\GW\GW_3145.axf: Error: L6218E: Undefined symbol ctype (referred from configura.o).
.\GW\GW_3145.axf: Error: L6218E: Undefined symbol __assert_func (referred from osdp_cp.o).

Not enough information to list image symbols.
Not enough information to list load addresses in the image map.

I have searched one by one for those files, and they really exist, for example “osdp_fill_random” or “osdp_crypt_setup” are defined in osdp_common.h
