unable to compile for ESP32 using Arduino IDE

[exiledyorkie]

Hi

I've used the library for an ESP8266 board which worked fine but now I want to use and ESP32 board. It won't compile for any board, if I remove the ESP8266Audio library, then all is fine. I've tried partitions to increase space and changed the board manager multiple times but nothing works. Any idea's please?

The error messages are below.

``` Arduino: 1.8.19 (Windows 10), Board: "ESP32 Dev Module, Disabled, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, Core 1, Core 1, None"

The Espressif compiler has a bug, it seems. I suggest opening an issue there. This code is pretty simple and others may be hitting the GCC bug, too.

Okay, thank you for the advice.

I have posted here;

Hi, I posted on the ESP32 github and they state that it is the lib itself. No idea to be honest.

Any thoughts, please?

I've pinged me-no-dev about it, we'll see. If they don't want to update their compiler then the only thing to do is remove the AudioGeneratorMIDI from any ESP32 builds.

Okay, I'll await and see how it goes. Appreciate the replies.
