Question

I tried to link a .lib library in a C++ project using codeblocks but i got a lot of erros like :

undefined reference to `_RTC_CheckEsp'
undefined reference to `_RTC_Shutdown'
undefined reference to `_RTC_InitBase'
undefined reference to `_RTC_CheckEsp'
undefined reference to `_RTC_CheckEsp'

What should i do to correct this errors ?
