Are you sure the SFML directory is under /usr/local/include? You didn't copy the include directory to /usr/local/include, thus creating /usr/local/include/include/SFML accidentally? The only thing I could think of other than that is /usr/local/include isn't in the list of directories to include for some reason.

You didn't copy the include directory to /usr/local/include, thus creating /usr/local/include/include/SFML accidentally?

Yes. Instead of copying only the contents of the include and lib folder, I had copied the whole include folder inside the /usr/local/include and the whole lib folder inside the usr/local/lib, but I corrected it now. But it is still not working. This error is coming :-

||=== Build finished: 34 errors, 3 warnings ===|

You will need to install the libraries which SFML is trying to reference. I don't use Ubuntu, though it looks like you will need to use your package manager to get libxcb-image0-dev, libxcb-randr0-dev, and libudev-dev.

If all else fails, you can install directly from the official repositories http://www.sfml-dev.org/tutorials/2.3/start-linux.php. I don't think it's the newest build, but It's also not that far behind.

I installed them. Now only the first three warnings are gone, but these 34 undefined reference errors are still showing :-

It is very far behind. Ubuntu 12.04 has SFML 1.6 in its repositories, whereas the current version is 2.3. I have already tried this 1.6 version but it was totally messed up. The syntax of its functions were very different from the new SFML versions.

So I downloaded the latest SFML for linux, placed its header files in usr/local/lib and placed the modules in usr/local/include, which are the standard locations for installing libraries. Now it is giving me these undefined reference errors in code::blocks, and also when I compile and run from the terminal.

Ah, I was anticipating you were at least using the latest lts (Ubuntu 14.04). I believe that's been updated to 2.1 for awhile now, which isn't the latest build but also not that far behind, feature-wise.

At last i upgraded my Ubuntu to 14.04, now there is no problem.
