我正在尝试在 Visual Studio 2010 项目中编译 companyClient.c，但即使我正确链接到 lib sapnwrfc.lib，我仍然会得到几个未解决的外部：

如果我在这里遗漏了什么，你能告诉我吗？我遵循了 pdf 文档中的指南，并且还阅读了：（http://help.sap.com/saphelp_nwpi71/helpdata/en/22/0430ba488911d189490000e829fbbd/frameset.htm）/NetWeaver RFC SDK/Programming with the NW RFC API/使用 NW RFC SDK 文件

我会很感激任何帮助。

我遇到过同样的问题。确保您正在编译到操作系统，而不是芯片。如果操作系统是 32 位，请使用此处找到的 32 位编译/链接选项，如果芯片和操作系统是 64 位，请按照 64 位条目的说明进行操作：
