未解析的外部 SAP NetWeaver RFC SDK 7.1 客户端示例 Visual Studio 2010

问：

我正在尝试在 Visual Studio 2010 项目中编译 companyClient.c，但即使我正确地链接到库，我仍然会得到几个未解析的外部问题：sapnwrfc.lib

你能告诉我我在这里是否遗漏了什么吗？

我按照pdf文档中的指南进行了操作，并且还阅读了以下内容： （http://help.sap.com/saphelp_nwpi71/helpdata/en/22/0430ba488911d189490000e829fbbd/frameset.htm） / NetWeaver RFC SDK/使用 NW RFC API 编程/使用 NW RFC SDK 文件

我将不胜感激任何形式的帮助。
