问题描述
所以我试图让clang
编译器正常工作..我自然的首选程序是以下极其复杂的代码:
So I'm trying to get the clang
compiler to work.. my natural first choice of program was the following extremely complex code:
#include <iostream>
using std::cout; using std::endl;
/* hello world.cpp */
int main()
{
cout << "Hello, world!" << endl;
return 0;
}
在命令行上,我做了:clang helloworld.cpp
,并且得到了以下不错的错误:
On the command line I did: clang helloworld.cpp
and I get the following nice error:
Undefined symbols for architecture x86_64:
