Installation issues on Apple M1

[ShubhamPandey28]

I tried installation using pip, but resulted in the following error

root ➜ /com.docker.devenvironments.code $ pip install fcwt

  ERROR: Failed building wheel for fcwt
Failed to build fcwt
ERROR: Could not build wheels for fcwt which use PEP 517 and cannot be installed directly

I added some changes in the cmake file
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -march=native -O2")
instead of "-mavx"

And I tried to install and use the C++ endpoint but I am getting segmentation faults on FCWT::cwt.

int main(){
    std::cout << "The server started." << std::endl;
    
    std::string filepath = "../static/sample.csv";
    int nchannels = 6;

    std::vector<std::vector<float>> data = readCSV(filepath, 6); // this part will be replaced with an active socket connection received
    std::cout << "File read successfully. Size " << data.size() <<","<<data[0].size() << std::endl;

    int sampling_rate = 44100;
    int nframe = 128;
    int nsamples = data[0].size();
    int fstart = 1, fend = 64;


    Morlet morlet(2.0f);
    Wavelet *wavelet = &morlet;
    int nthreads = 8;

    FCWT fcwt(wavelet, nthreads, true, false);

    Scales scales(wavelet,  FCWT_LOGSCALES, sampling_rate, fstart, fend, nframe);


    std::vector<MatrixXcf> spectrum(nframe, MatrixXcf::Zero(nchannels, nsamples));

    std::cout << nchannels << std::endl;
    std::vector<complex<float>> spec(data.size()*data[0].size() + 5, 0);
    std::cout << spec[0] << std::endl;

    for (int i = 0; i < nchannels; i++)
    {
        std::cout << i << std::endl;
        fcwt.cwt(&data[i][0], nsamples, &spec[0], &scales);
        std::cout << "good" << std::endl;
        std::cout << spec[0] << std::endl;
    }
    

}

How should I rectify this?
