c++ - XCode 4.4.1 - C++ - Apple Mach-O 链接器 (ID) 错误 - 找不到架构 i386 的符号

Question

我在 XCode 4.4.1 中编写了一些简单的 C++ 程序，每当我编译它们时，我都会收到以下错误:

"Main()", referenced from:
mainWrapper() in libStanfordCPPLib.a(startup.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

它是否在 libStanfordCPPLib.a 中引用了 mainWrapper()？提供了后一个​​文件，是否可以修改内容？否则，我是否需要进行更改以消除对 mainWrapper() 的引用？谢谢。

Undefined symbols for architecture i386:

似乎无论您使用的是什么库，都希望您定义一个名为 Main() 的函数(注意大写的 M)，而您还没有这样做。
