Curl simple https request returns nothing C++ - c++

Question

I'm using Visual Studio C++ 2010 and it's working just fine with cURL but the problem is that https requests returns nothing. instead of showing the output:
#include "StdAfx.h"
#include <stdio.h>
#include <curl/curl.h>
#include <conio.h>
int main(void)
{
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://www.google.com");
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
_getch();
return 0;
}
This code for example, it's just a https request to Google, but it returns nothing just because it starts with https. and if I take away the "s" of https, it works just fine: "http://www.google.com.br" shows the result normally. what am I missing here? I'm using the example from the cURL.
I tried with other websites and same thing happened. :/ like https://www.facebook.com
Btw also if you guys know how do I store the webpage content in a string, I would be glad to know.
Thanks in advance. :)

This simple example works for me:
#include <stdio.h>
#include <curl/curl.h>
int main(void)
{
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
/* First set the URL that is about to receive our POST. This URL can
just as well be a https:// URL if that is what should receive the
data. */
curl_easy_setopt(curl, CURLOPT_URL, "https://www.google.co.uk");
/* Perform the request, res will get the return code */
res = curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
}
return 0;
}
I got the source code and built the library long time ago but I'm sure I enabled the SSL support before compiling the sources. Make sure you have OpenSSL installed and (in case you're working under Linux) you have the PKG_CONFIG_PATH variable initialized properly. These are two options you specify when executing the configure script.
--with-ssl=PATH Where to look for OpenSSL, PATH points to the SSL
installation (default: /usr/local/ssl); when
possible, set the PKG_CONFIG_PATH environment
variable instead of using this option
--without-ssl disable OpenSSL
I hope it helps.
