我正在使用 Fedora 18（带有 Gnome），我已经安装了 gcc 和 gcc-c++，当我使用gcc -o slowka.o slowka.cpp命令时，我看到以下错误：
slowka.cpp:(.text+0x1b): undefined reference to `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string()'

collect2: error: ld returned 1 exit status
我不知道这是什么原因。我的代码：
#include <cstdio>
#include <iostream>
#include <string>
using namespace std;
int main()
{
printf("Witaj w aplikacji dodającej słówka ! Czy chcesz włączyć aplikację w tryb permanentny (t/N) ?\n");
string x;
scanf("%s", &x);
if(x != "t" && x != "T")
{
printf("Wybrano tryb \"jednego słówka\" !\n");
return 0;
}
return 0;
}
