如何在 netbeans (linux) 中链接库?

I'm trying to write a program in c++ to analyze sound. I want to use libsndfile library. I added an option -lsndfile to g++ compiler options. But I get the error: WavReader.cpp:18: undefined reference to `sf_open'

如何链接库?请帮忙！

#include <cstdlib>
#include "WavReader.h"
#include <sndfile.h>
#include <iostream>


namespace SA {

    WavReader::WavReader(char* fileName, SoundProcessor* soundProcessor) {
        this->fileName = fileName;
        this->soundProcessor = soundProcessor;
    }

    void WavReader::readFile() {
        SNDFILE* sf = NULL;
        SF_INFO info;
        info.format = 0; 
        sf = sf_open(this->fileName, SFM_READ, &info);

    }

    WavReader::~WavReader() {
    }
}

推荐答案

project properties -> linker -> libraries -> add option -> another option: -lsndfile
