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，都会出现以下错误：

"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)

它是在引用mainWrapper()inlibStanfordCPPLib.a吗？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 的引用mainWrapper()？谢谢。

更多细节：

Ld ./BlankProject.app/Contents/MacOS/BlankProject normal i386

Undefined symbols for architecture i386:
"Main()", referenced from:

似乎您使用的任何库都希望您定义一个名为Main()（注意大写 M）的函数，而您还没有这样做。
