C++ :: Peculiar Libcurl Library Error

I have been trying to get the libcurl library to work with the following program shown below but I have been getting the following error:

||=== Build: Debug in test3 (compiler: GNU GCC Compiler) ===|
objDebugmain.o||In function `Z8getstockPcS_':|
undefined reference to `_imp__curl_global_init'|
undefined reference to `_imp__curl_easy_init'|

I'm using Windows 7 64bit and Code::Blocks. Under 'build options' linker settings and link libraries I added all the libraries listed in the lib64 folder namely, libcrypto.a, libcrypto.dll.a, libcurl.a, libcurldll.a, librtmp.a, libssh2.a, libssh2dll.a, libssl.a, libssl.dll.a, libz.a, libz.dll.a, and libzdll.a. Under search directories compiler I included c:libcurl-7.34.0-devel-mingw64include and under search directories linker I included c:libcurl-7.34.0-devel-mingw64lib64.

#include <stdio.h>
#include <curl/curl.h>
#include <string>
#include <iostream>
#include <fstream>
#include <sstream>
#include <vector>
#include <ctime>
