Boost线程错误:未定义引用
Boost线程错误:未定义引用
提问于 2010-08-27 21:01:25
#include <boost/thread/thread.hpp>
#include <iostream>
void hello()
{
std::cout <<
"Hello world, I'm a thread!"
<< std::endl;
}
int main(int argc, char* argv[])
{
boost::thread thrd(&hello);
thrd.join();
return 0;
}我试着编译这个程序，得到了以下错误：
/usr/include/boost/thread/pthread/mutex.hpp:40: undefined reference to
`boost::thread_resource_error::thread_resource_error()'
/usr/include/boost/thread/pthread/mutex.hpp:40: undefined reference to

使用mt标签进行编译，即-lboost_thread-mt

我也有同样的问题，但是-lboost现在被弃用了参见askubuntu.com上的this answer。相反，您现在想要的makefile (至少在linux上)是：
-lpthread -lboost_thread ...Boost只是让你负责链接到你系统的线程库。

许多boost库都在头文件中完全实现。Boost.thread并非如此。它似乎没有链接到boost线程库中。检查链接器搜索路径。或者，正如Stargazer712对OP的评论所说，检查安装。您应该会在lib目录中看到类似libboothread.xxx-1_nn.o的内容。如果是这样，请尝试在您的链接步骤中显式引用它(类似于-L<path_to_lib> -lboost-thread-gcc-xx-1_nn)。如果不是，那么很明显你没有一个完整的安装。
