    help getting GLEW/GLFW setup in Visual Studio

    I'm trying to get OpenGL going in Visual studio C++ 2010 Express and I downloaded GLEW, GLFW, but I am having issues including them in proper pathway. For e.g. on GLEW instructions, it says to install : "include/GL/glew.h to {VC Root}/Include/GL

    but I don't have a GL directory just this:C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include.

    I'm using 64-bit Windows 7. I need simple help how to include these libraries in the pathway.

    It seems that the GL headers comes with Windows SDK. I have my include files from Windows SDK in the following directory: C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include

    And i also have a gl folder in the Include folder there with GL.h and GLU.h

    Those, in general, tend to have an OpenGL version outdated by decades, afaik.

    GLEW (or other libraries) interact with the driver directly to get function pointers for the new functionality.
    GLFW is just a little framework that eases the process of ..say.. creating windows and contexts in a portable way.

    So I also downloaded Windows SDK, and I want to get GLEW working, but are they outdated as manasij7479 indicates? But GLU, GL not same as GLUT, right? I would like to use GLEW and GLFW (as oppose to FreeGLUT and I understand GLUT has not been updated in more than a decade) as a good tutorial I found is teaching modern OpenGL (so 3, 4). And it tells me to use CMake. I find it confusing but I'll give it a go first. Can I just build manually w/ Visual Studio C++ 2010 Express that I'm using?

    So I found another tutorial and may use both (as this new one focuses on graphics programming in general), but uses OpenGL when necessary, but it chooses to use the windowing scheme w/ FreeGLUT as oppose to another tutorial (that focuses on modern OpenGL so versiion 3,4) that uses the windowsing scheme: GLFW. Can I have both co-exist in .../Windows SDK/GL/ ? Then there's also a header of:
    Code:
    #include <glload/gl_3_2_comp.h>
    . This is overwhelming to get started, so I should include glload lib into .../Windows SDK/GL/ as well? Any help please.

    Also in VS C++ 2010 Express that I'm using, I tried build a simple program, but I get these errors:
    'playground.exe': Loaded 'C:\Users\Documents\Visual Studio 2010\Projects\playground\Debug\playground.exe', Symbols loaded.
    'playground.exe': Loaded 'C:\Windows\SysWOW64\ntdll.dll', Cannot find or open the PDB file
    'playground.exe': Loaded 'C:\Windows\SysWOW64\kernel32.dll', Cannot find or open the PDB file
    'playground.exe': Loaded 'C:\Windows\SysWOW64\KernelBase.dll', Cannot find or open the PDB file
    'playground.exe': Loaded 'C:\Windows\SysWOW64\msvcp100d.dll', Symbols loaded.
    'playground.exe': Loaded 'C:\Windows\SysWOW64\msvcr100d.dll', Symbols loaded.
    The program '[10524] playground.exe: Native' has exited with code 0 (0x0).

    Why do they make it so hard to set up VS, OpenGL...

    I just included
    Code:
    #include <Windows.h>
    , these are the headers I have so far:
    Code:
    #include <stdlib.h>
    #include <GL/glew.h>
    #include <GL/glfw.h>
    #include <Windows.h>
    #include <GL/glm/glm.hpp>
    but now I'm getting these errors when building the program:
    1>------ Build started: Project: playground, Configuration: Debug Win32 ------
    1>main.obj : error LNK2019: unresolved external symbol _glfwGetWindowParam referenced in function _main

    Also, I don't need to have two versions of Windows SDK, right? I have:
    1) C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A
    2) C:\Program Files\Microsoft SDKs\Windows\v7.0

    You need to LINK that library, not only include its headers.

    What is meant by linking the library? I already added the GLEW/GLFW into the C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include\gl\ and I also included glm as well as the lib files from GLEW/GLFW into C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib\. And should I delete v7.0 in Program Files (64bit) of Windows SDK. I'm using Program(x86) Windows SDK which is v7.0a or should I keep both. I'm using Windows 7 64-bit.

    I opened in VS, Properties->Linker and these are the dependencies I have: kernel32.lib
    user32.lib
    gdi32.lib
    winspool.lib
    comdlg32.lib
    advapi32.lib
    shell32.lib
    ole32.lib
    oleaut32.lib
    uuid.lib
    odbc32.lib
    odbccp32.lib

    Please I need major help anyone

    I tried to link: glu32.lib, but in the System32 dir, I only have: GlU32.Lib, is this the same thing?

    Also, now I turned on warnings and the messages I get when building:
