IDE won't compile with Pro Micro Leonardo

Projects Programming

The IDE kept bugging me about updating to 2.0.4. so I did so and then I tried compiling a script onto my brand new Pro Micro, which produced this code:

In file included from C:\Users\FunkyMunky\Documents\Arduino\libraries\Control_Surface\src/MIDI_Interfaces/USBMIDI/USBMIDI.hpp:100:0,
                 from C:\Users\FunkyMunky\Documents\Arduino\libraries\Control_Surface\src/MIDI_Interfaces/USBMIDI_Interface.hpp:4,

          ^~~~~~~~~~~

Compilation error: exit status 1

My Pro Micro is on COM 6. The code, thankfully, still compiles on my Arduino UNO but, alas, the Pro Micro is the one I really want to work with.

Any idea of what's going on?

It can't find the library files. Try re-installing the library first. There may be more going on than that, though...

Yes, that's what it looked like to me as well, so I re-installed Control Surface, but still, no go.

IDE 2.0 is new. What were you using before that?

5

Yeah, I stupidly just updated without checking the version I had first. So I don't know what I had before. I installed it 1-1 1/2 years ago though. Any ideas on how to find that out? I was thinking of rolling back to the previous version.

As I understand, 2.0x has categorical changes vs. previous ones, some bugs are being worked out (I mean, a lot more vs. say 1.89 that I use). So it's not impossible. But maybe you mean, a previous version of 2.0. Heck, sometimes a bug fix breaks something.

That seems to be the wrong library to re-install. You have to (re)install the MIDIUSB library.

I have no experience with the libraries mentioned. I installed the control surface library and compiled the first example in IDE 2.0.4 without problems. Looking at the verbose output, I see lines with

"-Ic:\\Users\\sterretje\\Documents\\Arduino\\libraries\\MIDIUSB\\src"

This indicates that you need the MIDIUSB library. I had it already installed (no idea why, I never had a need for it); timestamp is from 2021.

Your topic is not related to IDE installation problems and hence has been moved to a more suitable location on the forum.

Yes, after hours of researching, I finally figured out that A. as a Pro Micro/Leonardo, it needs another library with which to be set up as a USB/MIDI Device, and B. upon reading the various instructions for Control Surface, I did, indeed figure out that what I needed was MIDIUSB Library. So I found the library, successfully installed it, and all the errors went away. My Pro Micro is now working like a champ as a MIDI Device.

Thanks for the help.

Great :+1:
