我在让 http-client 工作时遇到问题。我已经安装了本指南中的 C++ REST SDK。
我的操作系统是 Debian GNU/Linux 8.3 (jessie)。我也在 Ubuntu 14.04.3 LTS 上测试过，
构建库并运行测试后会出现问题。使用“make test”，输出如下所示：

The following tests FAILED:
1 - httpclient_test (Failed)
When running './test_runner *_test.so' the errors are:

所有其他测试均通过。我不知道我将要做什么。在 Windows 上，我的代码运行良好，在 Linux 上，使用 http_client 发送 http 请求时出现错误。
有谁知道为什么会这样？
