使用boost的thread库时遇到一个奇怪的问题

Neverwinter

这是我第一次使用boost的thread库，出错代码如下
[code:1]
//thread.cpp
#include <boost/thread.hpp>
#include <iostream>

boost::mutex io_mutex;

struct count
{
    static int num;
    int id;

    count(): id(num++) {}

    int do_count(int n)
    {
        for(int i=0; i<n; ++i)
        {
            boost::mutex::scoped_lock lock(io_mutex);
            std::cout << id << ": " << i << std::endl;
        }
        return id;
    }
};

int count::num = 1;

int main(int argc, char* argv[])
{
    count c1;
    boost::thread thrd1(boost::bind(&count::do_count, &c1, 10));
    thrd1.join();
    return 0;
}
[/code:1]

在FC4下用g++ -o thread thread.cpp进行编译时，报如下错误

也在FC3下试过，有同样的报错。我的FC3和FC4在安装后都没有进行什么改动，相关设置都是默认的。

lanche

请贴出具体的编译命令。

就这个啊
g++ -o thread thread.cpp

有没有人知道阿，急用

你的boost没有装好

不会吧，FC3和FC4安装时都自带了boost
