Hi! You also need to install the Windows SDK from Microsoft.

@Pavanj you may want to take a look at this answer.

@Wieland Thanks for the info.
Do I need to install windows SDK for visual studio 2017?

Pavanj

@Pablo-J.-Rogina Thanks for the info I will check it

@Pavanj You need the Windows SDK for Windows 7.

@Pablo-J.-Rogina Thanks for the hint, but that topic on SO is about the GLUT library. The OP needs the OpenGL header files.

@Wieland I am able to install windows sdk for win7,but while compiling the qt 5.9 example I got the below error
":-1: error: Failed to retrieve MSVC Environment from "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat":
'chcp' is not recognized as an internal or external command,
operable program or batch file."

On the windows command prompt, check if chcp can be located:

C:\Users\YourName> where chcp

If it can't be located, your PATH environment variable is broken.

@Wieland After running the command I got the below message
"C:\Windows\System32\chcp.com" and I added the "%SystemRoot%\system32" to environment variable
'chcp' is not recognized as an internal or external command issue fixed but still getting below error message

""C:\Qt\Qt5.9.0\5.9\msvc2017_64\include\QtGui\qopengl.h:139: error: C1083: Cannot open include file: 'GL/gl.h': No such file or directory

Is there any other things to be done to get rid of the problem?

Pavanj

Hi All,

Let me know is there any work around for this problem?

Thanks,

Hi @Pavanj,

So do you now have the file GL/gl.h on your system? If yes, please post the path where the file is located.

Thanks.

Hi aha_1980,

Thanks for the replay
I am able to find the gl/gl.h in below folders

C:\Program Files\Microsoft SDKs\Windows\v7.1\Include\gl
C:\Program Files\Microsoft SDKs\Windows\v7.0\Include\gl
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\gl
