Arduino multiple definition

Jurg · April 12, 2021, 2:26pm

Hello,

I’m rewriting the Arduino example for my project. I want to use this example in a custom class instead of the main file. I include using #include <xxxxxx_inference.h> in my header file.
The problem is that I’m getting a lot of multiple definition error messages like the ones here, starting with ei::spectral::processing::spectral_power_edges.

Full error:

Can someone help me to get this working?

Hey, I’m the one who you mention in that post. I might be able to help you. Do you think you can provide a minimum reproducible code?

Jurg · April 13, 2021, 6:41am

#include "Edge.h"

Edge::Edge()
{
}

ei_impulse_result_t Edge::ai()
{
    ei_impulse_result_t result = {0};
    unsigned short featureAmount = FeatureCollector::getInstance().getFeatureCounter();

    float* features = FeatureCollector::getInstance().getFeatures();

    signal_t features_signal;
    features_signal.total_length = sizeof(features) / sizeof(features[0]);
    features_signal.get_data = &raw_feature_get_data;

    EI_IMPULSE_ERROR res = run_classifier(&features_signal, &result, false /* debug */);
    return result;
}

int raw_feature_get_data(size_t offset, size_t length, float *out_ptr)
    {
    memcpy(out_ptr, FeatureCollector::getInstance().getFeatures() + offset, length * sizeof(float));  
    return 0;
 }

Edge.cpp

#ifndef MY_EDGE_H

#define MY_EDGE_H

#include <drilling_inference.h>

#include "FeatureCollector.h"

class Edge

{

public:
  Edge();
  ei_impulse_result_t ai();

};

int raw_feature_get_data(size_t offset, size_t length, float *out_ptr);

#endif

edge.h

I just placed the example code into a class.

janjongboom · April 13, 2021, 7:59am

@Jurg do you also have #include <drilling_inference.h> in your sketch? Can you remove it there?

Or move the #include to the cpp file.

Jurg · April 13, 2021, 8:08am

No, the Edge.h-file is the only file with #include <drilling_inference.h> in it. I moved the #include to the Edge.cpp-file and it gives me the same error messages.

PHAN · April 13, 2021, 11:25am

Can you try having just the .h file? Edge Impulse SDK ships as a header-only code so it is a bit tricky in terms of what to #include and where

// EDGE.h
#ifndef MY_EDGE_H
#define MY_EDGE_H

#include <drilling_inference.h>
#include "FeatureCollector.h"

class Edge
{

public:
  Edge()
  {
  }

  ei_impulse_result_t ai()
  {
    ei_impulse_result_t result = {0};
    unsigned short featureAmount = FeatureCollector::getInstance().getFeatureCounter();

    float* features = FeatureCollector::getInstance().getFeatures();

    signal_t features_signal;
    features_signal.total_length = sizeof(features) / sizeof(features[0]);
    features_signal.get_data = &raw_feature_get_data;

    EI_IMPULSE_ERROR res = run_classifier(&features_signal, &result, false /* debug */);
    return result;
  }

};

int raw_feature_get_data(size_t offset, size_t length, float *out_ptr)
    {
    memcpy(out_ptr, FeatureCollector::getInstance().getFeatures() + offset, length * sizeof(float));  
    return 0;
 }

#endif
