error: 'LocoNetStreamPico' does not name a type;

[Neleird]

Hi,

I'm trying to compile the 'Basic-Listener-Pico.ino' but this gives the error: 'LocoNetStreamPico' does not name a type;
I also get a WARNING: library LocoNet2 claims to run on esp32 architecture(s) and may be incompatible with your current board which runs on rp2040 architecture(s).

Like to use LocoNet2 on a RPi Pico W as a router to MQTT.

Hmmm.... try now... ;)

I've fixed those two errors and added the rp2040 architecture.

It looks like the newer 2.X IDE doesn't let me edit an example and save it into the library folder like the old 1.8.X IDe used to do when you created a ".development" flag file in the root dir of the library. Bit of a gotcha or at least different behaviour I need to check into

Hi Alex
Thank you very much. Quick response! Still the warning but compilation and upload succeeded. Lets start playing with LocoNet on the RPi Pico W...

Output result in IDE 2.2.1:

Hmmm... that is weird as I don't see that error. Can you check the contents of the library.properties file to make sure it has the line:

architectures=esp32,rp2040

As, I believe that is what should make the error go away. If I remove the rp2040 from the above line, I don't see the library in the list of File->Examples/LocoNet2, so I think it is working.

This is the full output I get when I compile in IDE 2.2.1:

So I'm unsure what to do next to debug this. Perhaps may sure you don't have two copies of the LocoNet2 library folder in the search path somewhere or one inside the other if you dragged the folder into the libraries folder, as I've done that before.
