How to build and configure boost.thread in CodeBlocks on Windows

I just wanna ask this very trivial question, I do not know if this the right question or if this one has been asked before and I know this can be solved by just visiting the documentation on boost. But I am really lost and stuck configuring boost.thread in C::B.

I am just a beginner when it comes to this and currently learning how to make windows app, well not seriously, just for learning purposes. I just notice that I really need the concept of multi-threading just to make it work. So I decided to use the Boost library, I did exactly what boost wiki says on building the libraries and I think I did not do something wrong.

I ran some couple of codes from the documentation that are header-only and it works flawlessly, but there are libraries included on boosts which requires special treatment of some sort including boost.thread which I am having difficulties. I know #includ-ing it on my file will not make Boost.thread works. I got errors from this basic code I found from an online tutorial (the very first code on multithreading page I found there) produces an error which says no such file directory.

and for which I know it doesn't detect my boost.thread library, I don't know where to go in this part. I've searched google but I think my best bet is to build the 1boost.thread1 separately as shown here, and I do not know what to do next.

Finally, after days of research and googling and cross referencing multitude of solution over the web I finally made the first code on the site I provided.

first what I did is that I included the extract_directory as the base under builtin fields in global variables. Then I went to project options and I clicked on the name of the project in hierarchy and search directories I added the $(#boost.include) on compiler tab and $(boost)\stage\lib on linker tab.

I started again from scratch in rebuilding boost(esp building boost.thread library) and I follow again what is exactly written on the documentation and then I finally got some error saying undefined reference error on Boost::system. What I did to solve this problem is to link my project against that boost.system (which is in my case was the file in my stage\lib folder).

I link this library on my project libboost_system-mgw34-mt-1_51.a

When I compile my program, an error occurred saying undefined reference to boost::chrono, which library name is:

libboost_chrono-mgw34-mt-1_51.a

and I also link my project against it, the same way I did for boost::system.

And it compiles! With no warnings whatsoever, what I learned from this experience is that I have to look for the libraries needed, what I am doing so far is to just link the boost.thread library and error just keep on saying undefined reference error to boost.system which I am not aware has something to do with boost threads or with other libraries(this is the first error I encountered before I messed things up). I think there are multiple function calls inside each boost libraries that are on another libraries so I have to link with them also that requires such call.

Thank you guys for your kind responses.
