ESP32 Compilation on Arduino IDE

[builderdev212]

This is my first time using the library, so there is a very good chance I have missed something during my installation. However, I wasn't to find any examples of a similar problem, so I am not sure exactly what I did wrong. I was attempting to run the PlayAACFromPROGMEM example program.

Board:

Arduino: 1.8.19 (Linux), 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"

Error compiling for board ESP32 Dev Module.

As I said, there's a chance I have something configured incorrectly, and if so, any help would be greatly appreciated. Thanks in advance!

Had the exact same error with esp32/2.0.3 but just uploaded the latest Zip file and worked fine for me.

As a quick check you can open AudioGeneratorMidi.CPP file and check for this.

include "AudioGeneratorMIDI.h"

if GNUC == 8

// Do not build, GCC8 has a compiler bug

else // GNUC == 8

It's pretty well covered in previous posts.

Thanks for the reminder. I recently redid the CI system to build ESP32-head, ESP8266-head, and RP2040-head, fixing several issues as they came up. But I forgot to bump the version number.

I've just updated the version to 1.9.7 and within 24 hours the Arduino Library Manager should pick up the update.

Again the compilation arising in esp32 boards....
