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.
What else is needed, I am stuck getting these libraries set up. Appreciate all the help.
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Those, in general, tend to have an OpenGL version outdated by decades, afaik.Quote:

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So I also downloaded Windows SDK, and I want to get GLEW working, but are they outdated as manasij7479 indicates?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:. This is overwhelming to get started, so I should include glload lib into .../Windows SDK/GL/ as well? Any help please.Code:#include <glload/gl_3_2_comp.h>
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\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, these are the headers I have so far:Code:#include <Windows.h>
but now I'm getting these errors when building the program:Code:#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glfw.h>
#include <Windows.h>
#include <GL/glm/glm.hpp>

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:
