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。

LINK : warning LNK4068: /MACHINE not specified; defaulting to X86


但是在编译静态库lib时,出错了

LINK : warning LNK4068: /MACHINE not specified; defaulting to X86

报错如下:

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。
