How to use OPENGL in Windows??

mrjj

hi and welcome
Did you try one of the examples ?
If you click on Welcome and then Examples, and then type opengl in the search box, there should be some
samples. Like "Boxes". Please See if those works.

Hi how did you get Qt in win 8 ?
Seems that you somehow did not get the opengl version.

Thank you!!:)

Um, Qt version is 5.5 Community V, In Qt homepage.

Did I download the wrong version? :(

@Mue22
Hi for 5.5 it should be dynamic so it should be included.. by default,
so im not sure what is going on.

Hi,

Which package did you use exactly ?

Mue22

@mrjj Yes, Thanks to your help!!:)

https://www.qt.io/download-open-source/#section-2

in above page,

Qt 5.5.0 for Windows 64-bit (VS 2013, 650 MB) (info) <<< downloaded this. and install include all option (all check-box true).

Thanks!!!!!:)

In that case, do you have VS2013 installed on your computer ?

FYI - I found the same thing:

Qt 5.5 commercial, MSVS2010 : Try and compile "boxes" demo and get a ton of OpenGL errors (e.g. "unresolved symbol __imp_glEnable"). The other OpenGL demos that use the newer modules work OK, but not the original stuff.

When using Qt 5.2 MSVC2010 32bit OpenGL commercial "boxes" compiles fine.

I don't see any option for an "OpenGL" version of Qt 5.5 for Windows.
Any suggestions?

So the solution to this is to add the following line to the .pro file:

win32 {
   LIBS += -lopengl32
}

That solves all of the unresolved symbol errors with Qt 5.5.
