How to compile boost thread using MinGW in Eclipse?

Question

#include <boost/thread/thread.hpp>
#include <iostream>

using namespace std;

void hello() {
    cout << "Hello world, I'm a thread!" << endl;
}

int main(int argc, char* argv[]) {
    cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!

    boost::thread thrd(&hello);
    thrd.join();
    return 0;
}

I am sure there is nothing wrong with the code above because I have tested it on Microsoft Visual Studio Express Edition. But it doesn't compile in Eclipse.

I'm doing this on Windows machine, I am using Eclipse Kepler with MinGW toolchain, I install boost in this directory D:/tool/boost_1_54_0 with this command ./b2 install --with-thread --libdir=stage/lib --includedir=stage/include --build-type=complete stage toolset=msvc. I have configure additional include directory, library path, and the thread library, which is boost_thread-vc110-mt-1_54 and libboost_system-vc110-mt-1_54, in Libraries (-l) section (project properties > C/C++ build > Settings > MinGW C++ Linker > Libraries)?

This is the output of the compilation, do you see any clue on it?

-llibboost_thread-vc110-mt-1_54

should be

-lboost_thread-vc110-mt-1_54

I works for me with boost_1.45 with following command line options

-IC:\MinGW\boost_1_45_0 -LC:\MinGW\boost_1_45_0\stage\lib -lboost_thread-mgw46-mt-1_45

I notice that your library name contain `mgw46`, and mine one showing `g++ "-LD:\\tool\\boost_1_54_0\\stage\\lib" -o Cpp2.exe "src\\Cpp2.o" -lboost_thread-vc110-mt-1_54 -lboost_system-vc110-mt-1_54` during compilation, does it matter? I mean do I need to configure MinGW toolset during boost compilation? Referring to the documentation, by specifying `toolset=gcc` will automatically configure GCC/MinGW compatible libraries for boost. – huahsin68 Sep 07 '13 at 10:26
@huahsin68 probably that's another issue, you need to build boost libraries using [Mingw](http://stackoverflow.com/q/4926990/1870232) – P0W Sep 07 '13 at 10:36

First run bootstrap.bat mingw and then b2 toolset=gcc in boost_1_##_0/.

You should, after some time, end up with a populated boost_1_##_0/stage/lib folder containing libboost_thread-mgw48-mt-1_55.a (or similarly named).

You will want to then add boost_1_##_0/stage/lib as a library path for the MinGW C++ Linker in the project properties and add boost_system-mgw48-mt-1_55 & boost_thread-mgw48-mt-1_55 as libraries without the lib prefix and .a ending. (Order may also matter so try putting system first if it isn't)
