How can I debug arduino libraries

Hello,

I am using GDB on ESP32 and I would like to set a breakpoint in an arduino library to be able to use the stack trace to find the location in my application where the library-function is called. 
How can I do this? 
The library sourcefile is WiFiClient.cpp in the arduino/esp32 directory structure ( ies\WiFi\src\" ).

I think the question is "how to see the library sources in the solution explorer so that you can set break points"?

When a project is open and active, there are three ways:-

1) Click "vMicro>Show Hidden Files". That "toggles" the core and library sources in/out of the project. 

or

2) Switch on "vMicro>Add Library>Create Shared Project When Including Libraries", then re-add the libraries to the project. If the library headers are already #included in the .ino code then only the shared project will be created, it doesn't cause a library to be added twice. The "Add Library" menu also has options to clone/copy the library to the local project/solution. That can work better if your libraries are in a location where you do not have permissions to create files. The permissions issue normally only applies to VS when not in Admin mode and when a library is located under "program files/arduino ide"


2) is recommended unless you often switch board architecture for the same project, then 1) is recommended.

Does this help?

I have chosen to copy the libraries to the project directory because this makes the project (more) self-contained and no longer dependant on (bugs in) library-updates in the standard locations.

After that "vmicro/show hidden files" did the trick. I did totally overlook this option.

Thanks!
