Importing Keil Project Linker C library files missing Error: L6218E: Undefined symbol

DS1

Hi ,

Imported a Keil UVISION (5.38) project to ARM DS 2023 using the import tool.

Using: 

Arm C Compiler for Embedded 6.16.2. LLM.

Arm FuSa RTS CM4_noMPU  

Solved  a lot of compiler issues, mostly missing  .h files, but now

I am getting a lot of these linker issues with c library:

    Hi

    It looks like the linker cannot find the C libraries.

    I can reproduce similar errors if I link a test project with the option "--no_scanlib", or set "Prevent scanning of system libraries" in Project > Properties > C/C++ Build > Settings > Arm Linker 6 > Libraries.  Please check that option has not been set accidentally.

    If you need more help, please send your linker command-line.
