OpenGL Review

Sid Kraft 46

Running Visual Studio, C++ trying to access the OpenGL Library functions. Per provided instructions, I did the following:

-Created a folder in my system C:\OpenGL Library

-Went to C:\Program File (x86)\Windows Kits\10\lib\10.0.19041.0\um\x64\opengl32.lib, copied the file opengl32.lib to my folder above

-Opened my Visual Studio, C++ project, issued the following

  -Project

  -Configuration Properties

  -Linker

  -Additional Library Directories C:\OpenGL Library\opengl32.lib

Back to the project, issued Rebuild

(have the include #include <GL/gl.h>)

same linker error _glTranslate(-.3,0.,0.) program not found? Getting frustrated as I have followed the advice given in several instances, all makes sense but nothing seems to work. The linker does not seem to find the windows library program. Sid Kraft

Why are you copying OpenGL32.lib? The Windows SDK is automatically in the library paths.

The difference in numbers is irrelevant here, the version numbers will automatically change with your Visual Studio setup.

Anyway, all you have to do to link against OpenGL32.lib is tell the linker to reference the library. The two ways to do this are:

Add OpenGL32.lib to Additional Dependencies in the linker settings.

Use the #pragma directive to tell the linker to reference OpenGL32.lib.

So either:

or

will reference it.

Also notice, in the last screenshot, I also show the project bulding correctly without error referencing OpenGL32.lib and calling glTranslatef. So the linker is also correctly referencing the library and is able to find the function.

Hello @Sid Kraft ,

Thanks for your question.

It appears the issue may be that Visual Studio does not automatically include the OpenGL library during the build process. Because OpenGL is typically included within the Windows SDK, copying opengl32.lib into a new folder might not be necessary. Visual Studio is generally already configured to locate the original file.

You can refer to these following steps:

Open your main C++ code file.
Add this line near the top, right below your #include <GL/gl.h> statement:

#pragma comment(lib, "opengl32.lib")

Rebuild your project.

For official details on how this code command works, please review Microsoft's documentation: pragma comment (C/C++).

I hope this addresses your question. If this response was helpful, please consider following the guidance to provide feedback. Thank you.

The issue is the property value being used. Additional Library Directories must contain a directory path, not the .lib file itself.

Use this setup instead:

In Project > Configuration Properties > Linker > General > Additional Library Directories, enter only the folder path: C:\OpenGL Library
In Project > Configuration Properties > Linker > Input > Additional Dependencies, add the library file name: opengl32.lib
If the path contains spaces, wrap it in double quotes. Unquoted paths can cause linker path parsing problems.
Verify the library matches the project architecture. If the project is building for x64, use the x64 library. Mixing 32-bit and 64-bit libraries causes linker failures.
There is no need to copy the library to a separate folder if the original Windows SDK library path is used correctly. The linker can search the directory specified in Additional Library Directories.
If the error still says the file cannot be opened, check for these common causes:
- incorrect path spelling
- invalid drive/path
- the library name entered incorrectly
- separators entered incorrectly in Additional Dependencies

For Visual Studio, the expected pattern is:

Linker > General > Additional Library Directories = folder containing the library
Linker > Input > Additional Dependencies = library file names

If multiple libraries are entered directly in Additional Dependencies, separate them with spaces, or use the Edit dialog and put each one on a new line.
