I'm new to uVision for a University project and since trying to get my code to build on my PC at home I get this error with any code I try to compile. Anyone know any way to fix this? I've been racking my brain for hours trying to find a solution as I can't work on my project if the code won't even build. Thank you.

Hi I'm still having issues with this. Even with an example project downloaded directly from Keil, it still gives me this error: Undefined Symbol APBPrescTable, is there anything I can add to my code that would fix this?
Build one of the example or template projects. From *ST* https://www.st.com/en/embedded-software/stm32cubef4.html
Seems like your project is missing some meta-data, either in the command line defines for compiler, or paths for include files. Or the source is just not built/included in your project. Check for #ifdef block code inclusion.
Or you are mixing things from inconsistent sources.
