Description

Hi I'm trying to use the ESP8266Audio library with an ESP32 dev board. 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?

I posted on the librarys github and was recomended posting here, due to it being a compiler bug.

Sketch

Just removing the ESP8266Audio library enables a compile. So it shouldn't be the sketch itself?

This has nothing to do with this repository :) Such issues should be fixed by the library maintainer (if he wants to support ESP32 in the same lib)

@me-no-dev Howdy, long time no chat!

This is a GCC internal compiler error (internal compiler error: in extract_constrain_insn, at recog.c:2210 . Whatever rev of the compiler is being shipped is barfing on some legal C code.

@earlephilhower maybe then you can help diagnose/fix this at https://github.com/espressif/crosstool-NG ? Was your library supposed to work? Name suggests ESP8266 :)

[earlephilhower]

The library actually built and ran on all earlier ESP32 toolchain releases (say from ~7 months ago??). It even has code to do audio-out using the ULP processor, in fact.

Since it seems to be a logic bug in the Xtensa compiler bits, most likely this is related to the specific GCC version you're building. Did you change it recently? I'll see what I can see in the repo you listed.

[me-no-dev]

versions before 2.0.0 used older 5.2.0 toolchain. We are on 8.4 now. (And I heard we will go even higher soon)
