Question

Getting error when using urldownloadtofile the error is : undefined reference to `URLDownloadToFileA'

#include <iostream>
#include <Windows.h>
#include <string>
#pragma comment(lib, "urlmon.lib")

using namespace std;
int main()
{   
    string dwnld_URL = "http://www.412312myfuptoload.com/downloadpage/Honeygain.exe";
    string savepath = "C:\\Users\\Ester\\Appdata\\Roaming\\Honeygain.exe";
    URLDownloadToFile(NULL, dwnld_URL.c_str(), savepath.c_str(), 0, NULL);

    return 0;
}

Answer 1

#pragma comment(lib, "urlmon.lib") works with MSVC (or compatible) compiler.

From the error and your previous question it seems you are using MinGW (ld linker) instead, which doesn't support it.

So you should link with the -lurlmon option.
