Code not building in PlatformIO but building in Arduino IDE - AVR Core issue?

Hi everyone,

I’m working in my first project (MIDI related - Control Surface lib) using PlattformIO. I’m trying to build the code available in this example:

https://tttapa.github.io/Control-Surface-doc/Doxygen/d2/d96/3_8FilteredAnalogReadSerial_8ino-example.html

Code Example 
#include <Arduino.h>
#include <Arduino_Helpers.h> // Include the Arduino Helpers library
 
#include <AH/Hardware/ExtendedInputOutput/AnalogMultiplex.hpp>
#include <AH/Hardware/FilteredAnalog.hpp>
#include <AH/STL/iterator> // std::back_inserter
#include <AH/STL/vector>   // std::vector
 
// Instantiate a multiplexer
CD74HC4067 mux = {
  A0,           // analog pin
  {3, 4, 5, 6}, // Address pins S0, S1, S2, S3
  // 7, // Optionally, specify the enable pin
};
 
// Convert the list of pins of the multiplexer to an array/vector
// of FilteredAnalog objects.
auto filteredAnalogs = [] {
  auto pins = mux.pins();
  std::vector<FilteredAnalog<>> v;
  v.reserve(pins.length);
  std::copy(std::begin(pins), std::end(pins), std::back_inserter(v));
  return v;
}(); // This is an immediately invoked lambda expression
 
void setup() {
  Serial.begin(115200);
  mux.begin(); // Initialize multiplexer
}
 
void loop() {
  // Loop over all FilteredAnalog objects in the vector
  for (auto &analog : filteredAnalogs) {
    analog.update(); // actually read the analog value and filter it
    Serial.print(analog.getValue());
    Serial.print('\t');
  }
  Serial.println();
}

But I’m getting the error:

According to the library maintainer, it’s probably related to an old compiler I’m currectly using. I should upgrade the Arduino AVR Core to at least version 1.8.1.
He also don’t support PlatformIO users and I don’t exactly how to proceed. I’m not sure exactly what’s the compiler version I’m using neither if it’s possible to update it (I have new installation in my environment).

Does anyone could help me on that?

Thank you in advance!

The code compiles when instructing PIO to use a newer compiler version.

Using the platformio.ini

[env:uno]
platform = atmelavr
framework = arduino
board = uno
lib_deps = 
    ; download latest library from github master
    Arduino Helpers=https://github.com/tttapa/Arduino-Helpers/archive/master.zip
platform_packages = 
    toolchain-atmelavr@~1.70300.191015

while still using the default build_flags (being -std=gnu++11), and the code

#include <Arduino_Helpers.h> // Include the Arduino Helpers library
 
#include <AH/Hardware/ExtendedInputOutput/AnalogMultiplex.hpp>
#include <AH/Hardware/FilteredAnalog.hpp>
#include <AH/STL/iterator> // std::back_inserter
#include <AH/STL/vector>   // std::vector
 
// Instantiate a multiplexer
CD74HC4067 mux = {
  A0,           // analog pin
  {3, 4, 5, 6}, // Address pins S0, S1, S2, S3
  // 7, // Optionally, specify the enable pin
};
 
// Alternatively, if you have a 3-bit mux:
// CD74HC4051 mux = {
//   A0,
//   {3, 4, 5},
//   // 7, // Optional
// };
 
// Convert the list of pins of the multiplexer to an array/vector
// of FilteredAnalog objects.
auto filteredAnalogs = [] {
  auto pins = mux.pins();
  std::vector<FilteredAnalog<>> v;
  v.reserve(pins.length);
  std::copy(std::begin(pins), std::end(pins), std::back_inserter(v));
  return v;
}(); // This is an immediately invoked lambda expression
 
void setup() {
  Serial.begin(115200);
  mux.begin(); // Initialize multiplexer
}
 
void loop() {
  // Loop over all FilteredAnalog objects in the vector
  for (auto &analog : filteredAnalogs) {
    analog.update(); // actually read the analog value and filter it
    Serial.print(analog.getValue());
    Serial.print('\t');
  }
  Serial.println();
}

By default for the Atmel-AVR platform and Arduino framework, PIO uses

meaning GCC 5.4.0. By setting the above platform_packages instruction, you get 7.3.0.

I’m not sure whether the default Arduino-Core has suddenly switched to a newer compiler now (after… ages), but I’ll check. In that case, PlatformIO should adapt its default settings, too.

That was so fast! :slight_smile:

This kind of configuration was not so clear for me. Thank you so much!
