gcc和鐺給我一個錯誤，而編譯

Question

這裏是我的簡單的測試代碼，

#include <iostream> 
int main(){ 
    std::cout << "SAO" << std::endl; 
    return 0; 
} 

和編譯如下

gcc -o test test.cpp 

，我有以下編譯錯誤命令。

Undefined symbols for architecture x86_64: 
"std::basic_string<char, std::char_traits<char>, std::allocator<char> >::size() const", referenced from: 
    std::__verify_grouping(char const*, unsigned long, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)in ccMFcxIz.o

我試過把-m32以防萬一，但仍然給我下面的錯誤。

ld: symbol(s) not found for architecture i386 
collect2: ld returned 1 exit status 

的gcc版本是4.2其通過的XCode 「命令行工具」 安裝。 操作系統是Mac OSX Mountain Lion。

我試過用gcc 4.7或3.1譁，但同樣的錯誤..

Ofcourse，編譯CPP代碼gcc會給你錯誤。你應該使用g++
