Just installed Arduino 2.0.3 - what is windows path to associated libraries?

Question

Just installed Arduino 2.0.3 and I attempted to build a sketch which includes a library that I manually installed in version 1.8.19 and it can't be found:

In my program I have #include <DS3231.h>

Now, attempting to compile it cannot find the library.

What is the path to the basic libraries in Arduino 2.0.3?

• Juraj: as in IDE1, it is the libraries folder in the sketchbook folder. the location of the sketchbook folder is in the Preferences dialog in the IDE

Answer 1

I found the location by examining the app while it was running.

The associated libraries are at:

%localappdata%\arduino15\Libraries

That will look like : C:\Users\<username>\AppData\Local\Arduino15\libraries

I created a new folder named DS3231 dropped in the .cpp, .h and .config files and now my sketch compiles with the #include <DS3231.h>

Kind of blows my mind that the Arduino 2.0.3 Libraries are found in a directory named Arduino15. Is that an old version or something?

Here's what I see in preferences -- don't see a location for user libraries:

arduino preferences

The best location will be your sketchbook location + a folder named libraries.

For example, in my case my sketchbook location is :

c:\users\<username>\dev\arduino

so my library folder should be:

c:\users\<username>\dev\arduino\libraries

• timemage: "in a directory named Arduino15. Is that an old version or something?" The 15 comes from the the 1.5.x series IDE which first introduced support for boards other than the original set of AVR boards, was carried into arduino-builder, and arduino-cli were it remains relevant to current day IDEs. It is not a normal place to add user libraries.
• raddevus: @timemage Where would the place be to add user libraries? I've added an image to the answer showing the Arduino 2.0.3 preferences but I don't see any location that would work. Do you have an alternative path in mind that works for 2.0.3? Thanks
• Juraj: do you see the location of the sketchbook folder in the Preferences dialog? then read my comment again and slow
