How to resolve undefined references to "__stack_chk_fail" in S32DS

[xiongsl]

Hi，

I create a new application project and add the command -fstack-protector-all. The compilation fails with the following message:

undefined reference to `__stack_chk_fail'

undefined reference to `__stack_chk_guard'

S32DS projects created from Example support the -fstack-protector-all command.

I didn't find any difference in the stack protection configuration between these two projects，Can you help me with this?

MCU:FS32K146, IDE:S32DS

I tested your project and it can be build without any issue. What's your S32DS version?
