我按照此处关于设置 CodeBlocks 以使用 GCC 4.7.1 的说明进行操作。我提到的页面上提供的示例编译得很好，但是当我尝试编译以下代码时，它随后产生了错误。我必须说我什至通过编译器设置（-std=c++11）设置编译器 C++11 标志，但仍然没有运气。编译失败的代码：
#include <iostream>
#include <thread>
#include <vector>
//This function will be called from a thread
void func(int tid) {
std::cout << "Launched by thread " << tid << std::endl;
}
int main() {
std::vector<std::thread> th;
int nr_threads = 10;
//Launch a group of threads
for (int i = 0; i < nr_threads; ++i) {
th.push_back(std::thread(func,i));
}
//Join the threads with the main thread
for(auto &t : th){
t.join();
}
return 0;
}
错误：
