Environment

  • Development Kit: ESP32-C3-DevKitM 1
  • Kit version (for WroverKit/PicoKit/DevKitC): [v1]
  • Module or chip used: ESP32-C3
  • IDF version v4.4-dev-4-g73db14240
  • Build System: idf.py
  • Compiler version riscv32-esp-elf-gcc.exe (crosstool-NG 1.24.0.123_64eb9ff) 8.4.0
  • Operating System: windows
  • (Windows only) environment type: [PowerShell
  • Using an IDE?: No, idf.py
  • Power Supply: USB

Problem Description

Build TFLite Hello world in EP32-C3 return
../components/tfmicro/tensorflow/lite/kernels/internal/cppmath.h:37:41: error: 'round' is not a member of 'std'
DECLARE_STD_GLOBAL_SWITCH1(TfLiteRound, round);

//Detailed problem description goes here.
When I try to build this example https://github.com/tensorflow/tensorflow/tree/master/tensorflow/lite/micro/examples/hello_world#deploy-to-esp32
in an ESP-32-C3, I get an error
../components/tfmicro/tensorflow/lite/kernels/internal/cppmath.h:37:41: error: 'round' is not a member of 'std'
DECLARE_STD_GLOBAL_SWITCH1(TfLiteRound, round);

If the target is ESP-32 there isn´t any problem

Expected Behavior

Get a binary file

Actual Behavior

Get an error

Steps to reproduce

I follow the instructions to deploy from the example. For ESP32-c3 I use idf.py set-target esp32-c3
For ESP32 idf.py set-target esp32

After idf.py build

// If possible, attach a picture of your setup/wiring here.

Hi @Robertou2,

Thanks for reporting this and providing a clear description of the error. Although we don't support third party projects, I can reproduce this issue using a simple C++11 test case so I've renamed the title.

#include <cmath>

int round_test(void)
{
    return std::round(3.33);
}

This seems like it will need to be fixed by updating the libstdc++ that is bundled with the ESP32-C3 toolchain. Will update once this is available.

Hi @projectgus,
thanks for your fast answer.

I have found a workaround using round() from cmath without std.

Thanks for letting us know about the workaround, @Robertou2 . This is still a bug in ESP-IDF (math headers should "just work"), so happy to keep it until we solve the root cause.
