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'
How to link the library? Please help!
#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() {
}
}
project properties -> linker -> libraries -> add option -> another option: -lsndfile
You need to link against -lsndfile library...make sure library path are included so it find library from correct location...check /usr/lib/ to make sure it is present on your system, or add path of correct location for your libs...
