Visual Studio 2017 debugger keeps looking for DLL's .obj file after project folder structure changed

Question

My setup

• Win10
• Visual Studio 2017 ver 15.9.15

While trying to step into a DLL API, VS throws the error at me:

Error: Unable to open file /path/to/old/folder/intermediate/file.obj. Error code = 0x80070003

This is different from questions such as

• VS2017 blocking on non-existing object files when debugging with pdb file

in that the error message clearly shows that the file was from an outdated location after I restructured the project.

I've tried

• Clean Solution and rebuild
• Tweak the debug config to use /DEBUG:FULL for all the DLL's and EXE's.

to no avail.

Any help is appreciated.

Answer 1

Solved it myself. All my DLL projects used to output to a location different from my main exe's folder. After I redirect those paths to the exe's folder and rebuild. The problem is gone. It's interesting that the app runs without DLL issues either way.
