Problem setting up OpenGL dev environment in Ubuntu 14.04

Question

Currently I'm using this tutorial to get started with opengl.So when I try to compile the example program :

#include <GLFW/glfw3.h>
#include <thread>

int main()
{
    glfwInit();
    std::this_thread::sleep_for(std::chrono::seconds(1));
    glfwTerminate();
}

using

g++ test.cpp -o test -lglfw3

to ensure that all is good with glfw I get this

In file included from /usr/include/c++/4.8/thread:35:0, from test.cpp:2: /usr/include/c++/4.8/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options. #error This file requires compiler and library support for the \ ^ test.cpp: In function ‘int main()’: test.cpp:7:10: error: ‘std::this_thread’ has not been declared std::this_thread::sleep_for(std::chrono::seconds(1)); ^ test.cpp:7:38: error: ‘std::chrono’ has not been declared std::this_thread::sleep_for(std::chrono::seconds(1));

So then I guessed I could use the flag that g++ suggested and compile it using

g++ -std=c++11 test.cpp -o test -lglfw3

But then things get weirder and g++ comes with this error(I will post only a part of it since it's a huge output overall but you will probably get the idea) :

x11_window.c:(.text+0x2d9): undefined reference to XSaveContext' x11_window.c:(.text+0x324): undefined reference to XChangeWindowAttributes' x11_window.c:(.text+0x3be): undefined reference to XSetWMProtocols' x11_window.c:(.text+0x417): undefined reference toXChangeProperty' x11_window.c:(.text+0x41c): undefined reference to XAllocWMHints' x11_window.c:(.text+0x48e): undefined reference toXSetWMHints' x11_window.c:(.text+0x49d): undefined reference to XFree' x11_window.c:(.text+0x4a2): undefined reference toXAllocSizeHints' x11_window.c:(.text+0x5ed): undefined reference to XSetWMNormalHints' x11_window.c:(.text+0x5fc): undefined reference toXFree' x11_window.c:(.text+0x613): undefined reference to XAllocClassHint' x11_window.c:(.text+0x66c): undefined reference to XSetClassHint' x11_window.c:(.text+0x67b): undefined reference to XFree' x11_window.c:(.text+0x6dc): undefined reference to XISelectEvents' x11_window.c:(.text+0x71e): undefined reference to XRRSelectInput' //usr/local/lib/libglfw3.a(x11_window.c.o): In functionhideCursor': x11_window.c:(.text+0x7bd): undefined reference to XUngrabPointer' x11_window.c:(.text+0x7fb): undefined reference to XDefineCursor' //usr/local/lib/libglfw3.a(x11_window.c.o): In function captureCursor': x11_window.c:(.text+0x880): undefined reference toXGrabPointer' //usr/local/lib/libglfw3.a(x11_window.c.o): In function `showCursor':

How could I fix this type of problem cause it really hurts my motivation to get into opengl. And please if you have in mind any better-hassle free guide for setting a proper opengl environment for deving with glfw and glew in linux/ubuntu , care to mention it.

Error undefined reference means that linker can't find function's definition. Probably, you should link X11 library to your program by console parameter -lX11. So, it should be g++ -std=c++11 test.cpp -o test -lglfw3 -lX11. I think you should link OpenGL library too (by -lGL).
