当我编译这段代码时： 

#include <iostream>
#include <curlpp/cURLpp.hpp>
#include <curlpp/Easy.hpp>
#include <curlpp/Options.hpp>

int main() {
    cURLpp :: Cleanup cleanup;
    std :: cout << "Hello world" << std :: endl;

    return 0;
}

通过控制台：

g++ main.cpp -lcurlpp

有很多错误，例如：

/usr/lib/gcc/x86_64-linux-gnu/4.9/../../../x86_64-linux-gnu/libcurlpp.so: undefined reference to `curl_getenv@CURL_OPENSSL_3'

仅与CURL_OPENSSL_3

我该如何解决？谢谢

Ubuntu 15.04, curl 版本 - 7.38.00, curlpp - 已安装sudo apt-get install libcurlpp-dev

在 Mint 17 上，我能够使用

g++ main.cpp -lcurl -lcurlpp

查看程序的库转储，您可能缺少以下可以安装的库apt-get：

libssl-1.0.0
libcurl4-openssl-dev
