Hi, I'm working with ESP32 and the adafruit seesaw library, which has a known bug....that has not been fixed for over a year.  I want to debug the adafruit seesaw library and am running into trouble.  Please bear with me:

The installed adafruit library is with the other installed libraries and exists in a folder named C:\Users\jimfr\OneDrive\Arduino\libraries\Adafruit_seesaw_Library.

I have a solution in VS2019 named Temptester_ESP32 which I'm using to test different sensors for my project.  That solution has several projects, one of which is named soilsensor_example.  This project is the focus of my question.  soilsensor_example lives in C:\Users\jimfr\OneDrive\Arduino\My Examples\soilsensor_example.  I copied the Adafruit_seesaw_library into the soilsensor_example folder.  My code has the following include: #include ".\Adafruit_seesaw_Library\Adafruit_seesaw.h".  VS finds this.  When I'm peeking at definitions in the Adafruit_seesaw.h, it is looking into the local version (I added a comment to the header file to tell which one I'm looking at).  

getting to the problem:  when I build soilsensor_example, I get errors in the attached....indicating that there are duplicate definitions of the methods.  When I look at the External Dependencies folder in the Solution Explorer (for that project), it lists Adafruit_seesaw.h twice.  The properties for those dependencies show that one is pointing to the standard library and the other is pointing to the local library.  I tried to remove the external dependency listed for the standard library by right clicking and cutting it....but I get an error from VS "The operation could not be completed. Not enough memory resources are available to complete this operation."  I don't believe this....there are 8 gigs of available RAM.  I shut VS down, restarted, and got the same error.

Soooooo, my questions:
1) am I approaching this the correct way....creating a local copy of header and .cpp with the intent of debugging the .cpp?
2) If I am approaching this the correct way, then is deleting the external dependency of the installed library the way to go?
3) what should be my next steps?

many thanks.......jim

Thanks.....that did it.  Because I wanted to debug a library that I didn't create, I also cloned it in the project.  I continued to get build errors until I added a new simple project to the solution, copied/pasted my code into the new project, added the library and cloned it to the project I just added, then removed the prior project that was getting the errors.  The build on the new project worked fine.  Thanks again.....jimf.
