我是LLVM的新手，并且想尝试万花筒示例。我的 PC是Windows 64位系统。我设法从源代码构建LLVM CMake。我设法用Visual Studio构建了万花筒的示例 .vcxproj文件的15 2017。第8章中构建的toy.exe运行良好 从命令行，我可以输入平均值的函数定义 如教程中所示。玩具将output.o写入D：\ llvm.bld \ Debug \ bin。
但是，当我想要编译和链接main.cpp时，如 我得到的教程： clang ++。exe：错误：链接器命令失败，退出代码为1143（使用-v 参见调用）。
完整的详细输出复制如下。您如何编译和链接 Windows 64位PC上的main.cpp和output.o？
问候，
