的XCode 4.4.1 - C++ - 蘋果的Mach-O接頭（ID）錯誤 - 符號（S）沒有找到i386硬件架構

Question

我已經寫在了XCode 4.4.1一些簡單的C++程序每當我編譯它們，我得到的以下錯誤：

"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) 

是它使得在libStanfordCPPLib.a到mainWrapper()參考？後面的文件被提供並且可以修改內容？否則，我是否需要進行更改以消除對mainWrapper()的引用？謝謝。

更多細節：

看來，無論圖書館使用的是希望你定義一個名爲Main()功能（注意是大寫字母M），而你還沒有這樣做。
