error compiling example sketch streams-i2s-a2dp

[rkb68]

Hello,

Using arduino-audio-tools 04f44f5 (commit of 2023-03-29)

Upon compiling in Arduino (1.8.19), I get this error:

In file included from /.../Arduino/libraries/arduino-audio-tools-main/src/AudioI2S/I2SStream.h:11:0,
from /.../Arduino/libraries/arduino-audio-tools-main/src/AudioTools.h:60,

#if ESP_IDF_VERSION > ESP_IDF_VERSION_VAL(4, 4, 0)

The is with the Sparkfun ESP32 library v 1.0.1 and the Espressif ESP32 library v 2.0.7

Has anybody else encountered this?
Thanks, rkb

What is Sparkfun ESP32 library v 1.0.1 ?
Maybe it destroys some functionality of the generic ESP32 library

I tested in Arduino (1.8.19) with ESP32 library v 2.0.7 and did not have any issues

The ESP_IDF_VERSION_VAL macro is part of #include "esp_idf_version.h" and can be used to check for the IDF version

I suggest that you try to reinstall ESP32 v 2.0.7

Thank you. The Sparkfun library I referred to is in fact the board support package for many of their ESP32 products. It usually coexists peacefully with the Espressif package, but evidently not all the time.

Success!

Thanks again; did not have HW available when replying earlier; can now compile without error by bypassing the Sparkfun library.

In case anybody else has this problem, I was able to select the board (Sparkfun ESP32 Thing Plus C) not from the "Sparkfun ESP32 Arduino" folder, but instead from the "ESP32 Arduino" folder, and everything works just fine.
