Solve undefined reference to 'boost: thread: start_thread () 'in eclipse3.6.1 ()'

Use the boost library to Write multi-threaded programs:

# Define boost_data_time_source
# Define boost_thread_no_lib

# Include <boost/thread. HPP>
# Include <iostream>

Using namespace STD;
Using namespace boost;

Void Hello ()
{
STD: cout <
"Hello world, I'm a thread! "
<STD: Endl;
}

Int main (INT argc, char * argv [])
{
Boost: thread thrd (& Hello );
// Wait until the thread ends
Thrd. Join ();
Return 0;
}

The console prompts an error during compilation:

At the same time, two lines in the source code are prompted with an error.

Solution:

Right-click the project and choose Properties.

 

Open the following settings page:

Open C/C ++ build on the left, find mingw C ++ linker --> libraries in the list under tool settings, and click the plus sign in the upper right corner of libraries, add "boost_thread ",

Click "OK", click "Apply", and then click "OK" to exit. Re-compile, no problem.
