Any luck compiling with Arduino ESP-32 3.x.x?

[andcolla80]

I can compile without issues using arduino-esp32 based on ESP-IDF 4.4, but have a lot of error when try to use the same code with some version (3.x.x) based on ESP-IDF 5.x.

My guess is some code is not compatible with the new standard GNU++17 used by GCC 11.

Does anyone ported this code to new api version?

Maybe I found the solution. I changed the menuIO/chainStream.h to the code below and successfully compiled using VSCode, ESP-IDF 5.1.4 and arduino-esp32 3.0.4. These are the latest versions, not tried with 3.1.0-rc1.

// menuIO/chainStream.h

#ifndef MENU_CHAINSTREAM_H
#define MENU_CHAINSTREAM_H

#include <Arduino.h>
#include "../menu.h"

namespace Menu {

  template<int N>
  class chainStream:public menuIn {
    public:
    menuIn* const* const inputs;
    chainStream(menuIn* const* inputs):inputs(inputs) {}
    int available(void) override {
      for(int n=0;n<N;n++) {
        int r=inputs[n]->available();
        if (r) return r;
      }
      return 0;
    }
    int peek(void) override {
      for(int n=0;n<N;n++) {
        int r=inputs[n]->peek();
        if (r>=0) return r;
      }
      return -1;
    }
    int read(void) override {
      for(int n=0;n<N;n++) {
        int r=inputs[n]->read();
        if (r>=0) return r;
      }
      return -1;
    }
    void flush(void) override {
      for(int n=0;n<N;n++) inputs[n]->flush();
    }
    size_t write(uint8_t v) override {
      for(int n=0;n<N;n++) inputs[n]->write(v);
      return 1;
    }
  };

} // namespace Menu

#endif
