Feb 14, 2002 GL.h is the header for OpenGL. Glu.h defines some handy functions and other utilities to help you. Glaux.h is the same a glu.h but its purpose is a little different. Basically glu and glaux are just extension libs, there not truely necessary to use opengl that may be why you havn't theard of them. Glut can be found here. The header gl.h is actually present in /System/Library/Frameworks/OpenGL.framework/Headers and as such should be found by cmake, especially since glut.h is in the same structure (simply replace OpenGL with GLUT) and is found just fine.
- In Visual Studio, create a Visual C++ 'Win32 Console Application'.
- In the 'Win32 Application Wizard', under 'Application Settings', check 'Empty project'. (The default is 'Precompiled header'. You don't need it.).
- After the project is created, right click on the project name and select 'Properties'.
- In the 'Property Pages' window, click Linker --> Input, and add the following files to the 'Additional Dependencies' line: freeglutd.lib glew32d.lib SOIL.lib assimp-vc140-mt.lib .
- Don't just copy the file names above. Your file name may be different from this example. For example, your files may be freeglut.lib and glew32.lib. So make sure your file names are correct.
- Note that since Visual Studio 2015, you no longer need to include opengl32.lib in 'Additional Dependencies'.

- If you use Assimp, glm, or SOIL in your program, you also need to add search paths to Visual Studio (VS) so that VS can find the header files from Assimp, glm, and SOIL. In the 'Property Pages' window, select 'VC++ Directories' and then select 'Include Directories'. Click on 'Edit', then add the following paths: 'assimp-xxxinclude', 'glm', 'Simple OpenGL Image Librarysrc'. (Note that I only give the relative path here. You'll need to add the complete path.)
- For newer version of Assimp, you also need to include assimp-4.1.0/build/include.
Figure 7. Make sure to include all the header file search paths.
- Close the project property window. Drag and drop an OpenGL source file into the 'Source Files' branch under the 'Solution Explorer' window. Now you should be able to build and run an OpenGL program. Try the sample program 'draw_vertex.cc' attached at the bottom of this page. If successful, you'll see this image.
How to specify the path of an external file in my program so that Visual Studio can find it?
When writing your OpenGL programs, you often need to load external files such as GLSL shaders, 3D model files, and image files. Sometimes Visual Studio cannot locate these files because the files are not on Visual Studio's default search path. Here's how Visual Studio searches for files and how you should set the file path:
- Assume your program builds successfully, and your program needs to load shader files from your disk. When you run the program from within Visual Studio (VS), VS will look for these files in the 'Working Directory'. To find the 'Working Directory', open Project Properties, select 'Debugging' --> 'Working Directory', you'll find the macro $(ProjectDir). Click on the down arrow icon on the right hand side of this text box, and select <Edit..>, the 'Working Directory' window will pop up. Click on the button 'Macros>>', and scroll down to find the full path for the macro $(ProjectDir).
- By default, the 'Working Directory' is the macro $(ProjectDir), which is the folder in which your VS project file resides.
- Solution #1: Set all file paths relative to the 'Working Directory'. This is the recommended practice.
- Solution #2: Copy all the external files into the 'Working Directory'. The code will be simpler -- you just need to specify the file name, without having to worry about setting the correct file path. But all the external files are placed in one directory, along with the VS project files. It's not well organized.
- Solution #3: Specify full path for all the external files in your program. You don't need to know where the 'Working Directory' is. But this is the least flexible solution. If you share the program with others, then they'll need to reset the path. If you move your project to another folder or reset your folder name, you'll need to reset the path.
- For example, on my computer there is a sample program whose VS project file 'sample.vcxproj' is at 'D:WorkTeachingCourses2014CSC4820-6820HomeworkHomework1samplesample'. When I create this project in VS, VS automatically sets $(ProjectDir) to this folder. This is the 'Working Directory' for this project.
- In the following code sample, the program tries to load two external files (e.g. shader files) with no path specified, VS will look for them in the 'Working Directory' ('D:WorkTeachingCourses2014CSC4820-6820HomeworkHomework1samplesample')
GLuint program = InitShader( 'vshader23.glsl', 'fshader23.glsl' );
Because vshader23.glsl is not under the 'Working Directory', the program will fail. - Solution #1: Set the file path of vshader23.glsl and fshader23.glsl relative to the 'Working Directory'. In my case, vshader23.glsl is under the folder 'D:WorkTeachingCourses2014CSC4820-6820HomeworkHomework1', which is two levels above the 'Working Directory'. So I set the file path as follows. This is the recommended practice.
GLuint program = InitShader( '..vshader23.glsl', '..fshader23.glsl' );
- Solution #2: Copy vshader23.glsl and fshader23.glsl to the 'Working Directory' ('D:WorkTeachingCourses2014CSC4820-6820HomeworkHomework1samplesample'). Then the code will be simpler but the files will be less organized.
GLuint program = InitShader( 'vshader23.glsl', 'fshader23.glsl' );
- Solution #3: Set the full path for each file. This is the least flexible and least elegant solution.
GLuint program = InitShader( '
D:WorkTeachingCourses2014CSC4820-6820HomeworkHomework1vshader23.glsl', 'D:WorkTeachingCourses2014CSC4820-6820HomeworkHomework1fshader23.glsl' );
If you run your program from the command line (not from within Visual Studio), then the shader files should be in the same folder as your executable file.
Example
Mac os x emulator for mac. 1. Install GLFW
First step is to create an OpenGL window. GLFW is an Open Source, multi-platform library for creating windows with OpenGL, to install GLFW first download its files from www.glfw.org
Mac os sierra icon pack for windows 10. Extract the GLFW folder and its contents will look like this
Download and install CMake to build GLFW. Goto www.cmake.org/download/, download CMake and install for MAC OS X
If Xcode is not installed. Download and install Xcode from Mac App Store.
Create a new folder Build inside the GLFW folder
Open CMake, click on Browse Source button to select the GLFW folder (make sure that CMakeLists.txt) is located inside that folder. After that, click on Browse Build button and select the newly created Build folder in previous step.
Now Click on Configure button and select Xcode as generator with Use default native compilers option, and click Done.
Tick on BUILD_SHARED_LIBS option and then click on Configure button again and finally click Generate button.
Welkin suite for os x 10.10. After generation CMake should look like this
Now Open Finder and goto /usr, create a folder name local if not already there. Open the local folder and create two folders include and lib if not already there.

Select install > My Mac and then click on run (Play shaped button).
It is now successfully installed (ignore the warnings).
To make sure Open Finder and goto /usr/local/lib folder and three GLFW library files will be already present there (If not then open Build folder inside GLFW folder and go to src/Debug copy all files to /usr/local/lib)
Open Finder and goto /usr/local/include and a GLFW folder will be already present there with two header files inside it by name of glfw3.h and glfw3native.h
2. Install GLEW
GLEW is a cross-platform library that helps in querying and loading OpenGL extensions. It provides run-time mechanisms for determining which OpenGL extensions are supported on the target platform. It is only for modern OpenGL (OpenGL version 3.2 and greater which requires functions to be determined at runtime). To install first download its files from glew.sourceforge.net
Extract the GLFW folder and its contents will look like this.
Now open Terminal, navigate to GLEW Folder and type the following commands
Now GLEW is successfully installed. To make sure its installed, Open Finder, go to /usr/local/include and a GL folder will be already present there with three header files inside it by name of glew.h, glxew.h and wglew.h

Open Finder and go to /usr/local/lib and GLEW library files will be already present there
3. Test and Run
Now we have successfully installed GLFW and GLEW. Its time to code. Open Xcode and create a new Xcode project. Select Command Line Tool then proceed next and select C++ as language.
Xcode will create a new command line project.
Click on project name, and under Build Settings tab switch from Basic to All, under Search Paths section, add /usr/local/include in Header Search Paths and add /usr/local/lib in Library Search Paths
Click on project name, and under Build Phases tab and under Link With Binary Libraries add OpenGL.framework and also add recently created GLFW and GLEW libraries from /usr/local/lib
Now we are ready to code in Modern Open GL 4.1 on macOS using C++ and Xcode. The following code will create an OpenGL Window using GLFW with Blank Screen Output.
