LInk Errors libSTM32Cryptographic_CM0_CM0PLUS.a

Hi, I am implementing ECDSA signing functionality based on some sample code in the package en.STM32CubeExpansion_Crypto_v4.0.1. I am getting the following linker error. What am I missing? Thanks!

c:\st\stm32cubeide_1.6.1\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.9-2020-q2-update.win32_1.5.0.202011040924\tools\arm-none-eabi\bin\ld.exe: ../STM32_Cryptographic\Lib\libSTM32Cryptographic_CM0_CM0PLUS.a(cmox_init.c.o): in function `cmox_initialize':

cmox_init.c:(.text+0x1a): undefined reference to `cmox_ll_init'

Hello @RKher.1​ ,

Make sure that the header file declaring the function is included in the include path, and add the directories with source files in them to the source folders.

Project properties -> C/C++ General -> Paths and Symbols -> Source Location

@Imen DAHMEN​ I was not able to get this resolved I included the STM32_Cryptgraphic folder in en.STM32CubeExpansion_Crypto_v4.0.1 which contains all the header files including cmox_crypto.h. Do you happen to know the name of the particular header file that I should include for this. My understanding was that including cmox_crypto.h would be sufficient. Thanks!
