Why can't the SysTick_Config function be directly located in the project file copied directly from STM32? [Copy link]

[SysTick_Config is defined in core_cm3.h, and core_cm3.h is referenced in stm32f10x.h] 1. First of all, all the files related to the project on other people’s computers are in one folder, and SysTick_Config can be directly located by “go to definition” on his computer. 2. I have newly installed MDK5 and have installed the support package correctly. After compiling, two stm32f10x.h header files (but they are actually the same) and core_cm3.h header files appeared in the project tree. SysTick_Config cannot be located by “go to definition”, as shown in the figure. (I am sure that no files have been deleted after directly copying the entire project folder) But why does this problem occur now? Other library files can locate the source, but this one can’t. Is there any other related settings?

You haven't compiled successfully yet. You need to compile it all to correctly locate the problem of environment configuration. Clear it and rebuild it
