[VS2010] 编译64位静态库lib提示fatal error LNK1112: module machine type 'x64' conflicts等错误的解决方案

环境

Win7 x64

Visual Studio 2010

程序写完，本想导出dll(x64)、lib (x64)，在动态链接库dll下编译成功。



但是在编译静态库lib时，出错了



报错如下：

1>—— Build started: Project: EditAlgoTestFrameWork, Configuration: Release x64 ——

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

原因

由于项目默认 /MACHINE属性值为X86，故在编译lib(x64)时，需要显式指定其值为X64

解决方案

项目右键属性(Properties) –> 配置属性(Configuration Properties) –> 库管理器(Librarian) –> 命令行(Command Line) –> 其他选项(additional Options)　　　指定/MACHINE值为X64：

/MACHINE:X64

保存并重新编译即可通过。
