espressif32 @6.5.0: mbedtls_sha1() fails to compile

[mhaberler]

I need to step back in espressif32 versions to isolate an i2c bug

[env]
platform = espressif32 @6.5.0
framework = arduino

then I get

what would you suggest? maybe bring in https://github.com/esp8266/Arduino/tree/master/libraries/Hash ?

thanks, Michael

edit: might be the old compiler version, looks like c++11 rather than c++17

Sorry, I can't reproduce this.

I tried building the PicoMQTT websocket_server example for the esp32 pinning the platform version (espressif32 @6.5.0). It compiles fine...

[mhaberler]

I'll post an example to reproduce, this is too convoluted
