当尝试使用Boost Threading库编译一些示例C ++代码时，我得到了这个编译错误：

我试图编译的代码是Boost线程的一些示例代码，但是我已经确定这些错误不是这个特定源代码所独有的：
#include <iostream>
#include <boost/thread.hpp>
using namespace std;
class MyRunnable {
public:
MyRunnable(int id, boost::mutex* mutex, boost::barrier* bar) {
this->id = id;
this->mutex = mutex;
this->bar = bar;
}
// The entry point for a thread
void operator()() {
for(int i = 0; i < 10; ++i) {
boost::mutex::scoped_lock lock(*mutex);
cout << "id: " << this->id << ", " << i << endl;
}
// all done, wait at the barrier.
// wait() returns when everyone has met at the barrier
bar->wait();
}
private:
int id;
boost::mutex* mutex;
boost::barrier* bar;
};
int main() {
boost::mutex io_mutex;
// this barrier will wait for two invocations of wait()
boost::barrier my_barrier(2);
cout << "Starting two counting threads..." << endl;
// the boost::mutex cannot be copied (for obvious reasons)
// so we must pass the pointer to the mutex.
boost::thread thread1(MyRunnable(1, &io_mutex, &my_barrier));
boost::thread thread2(MyRunnable(2, &io_mutex, &my_barrier));
thread1.join(); // wait for thread1 to finish
// Note how the program doesn't return until all threads are dead
return 0;
}
我是C ++编程世界的新手，我不知道出了什么问题。任何帮助将不胜感激。
