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，我都会遇到以下错误：

"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)

是否在mainWrapper()中引用了libStanfordCPPLib.a？提供后一个文件，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？感谢。

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

Answer 1

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

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