I just updated the Arduino IDE to Version: 2.0.0-rc9.3  
Date: 2022-09-05T09:30:11.600Z  
CLI Version: 0.27.0-rc.1 [c2af7c5a]

Now I cannot compile sketches that previously compiled without a problem. The verbose output seems to indicate a problem with the WiFiNINA server\_drive.cpp.o file. I don't see any way to clear the cache and recompile cleanly from within the IDE so I'm researching how to use the arduino-cli --clean from the Terminal app on my Mac to do this. Advice would be appreciated. Here is the verbose output from the IDE:

Hi @maulepilot. I see that there are two copies of all the source files of the WiFiNINA library. One of them has the expected name, while the other has a " 2" suffix on the name.

For example, here you can see there is a `WiFi 2.cpp` in addition to the expected `WiFi.cpp`:

> Using cached library dependencies for file: /Users/ameranda/Documents/Arduino/libraries/WiFiNINA/src/WiFi.cpp
>

I think this is the cause of the error.

Do you know how these " 2" files happened?

You should be able to fix the bug by uninstalling and then reinstalling the WiFiNINA library:

1. Select **Sketch \> Include Library \> Manage Libraries...** from the Arduino IDE menus to open the " **Library Manager**" view in the left side panel.

2. In the " **Filter your search**" field, type `wifinina`.

3. Select " **Arduino**" from the " **Type**" menu.

4. Hover the mouse pointer over the " **INSTALLED**" label on the "WiFiNINA" library entry.

5. You will now see the label change to an " **UNINSTALL**" button. Click the " **UNINSTALL**" button.

6. You will now get a dialog asking:

7. Wait for the uninstallation to finish.

8. Hover the mouse pointer over the "WiFiNINA" library entry in the " **Library Manager**" view.

Thank you. That worked. I think the second copy of the WiFiNINA library happened when I updated the Arduino IDE and received several prompts to update a bunch of libraries. I updated all of the libraries but didn't keep a list of which ones were being updated since it was so rapid.

You are welcome. I'm glad it is working now.

I haven't seen any other reports of this problem, nor experienced it myself during my beta testing work, but I will keep a close watch for any other occurrences of this problem in case it is caused by a bug in the IDE.

Please comment here on this forum topic if you run into the problem again.
