问题在V8引擎的Mac Pro X86_64中运行示例？

Question

最近，我尝试构建并运行谷歌v8的示例hello世界程序。 我的xcode版本是4.0.2GA，x86_64。

该指南的链接：get Started

但是，当运行命令： G ++ -Iinclude hello_world.cpp -o程序hello_world libv8.a -lpthread

的错误显示：

它应该是显而易见的，你正试图链接一个为另一个架构而建立的.a。查看How do I determine the target architecture of static library (.a) on Mac OS X?了解如何检查.a的目标架构。一旦你知道你可以重定向你的项目，或者为x86_64架构创建一个新的libv8.a。
