OpenGL: Version 0.0

[herotom99]

When go in the files drivers I have (about OpenGL):

For 32 bits:
-NvIFROpenGL.dll  (version: 10.18.13.6451)
-OpenCL.dll (version: 1.2.11.0)
-nvopencl.dll (version: 6.14.13.6451)

And 64 bits:
-OpenCL64.dll (version: 1.2.11.0)
-nvopencl.dll (version: 6.14.13.6451)

I don't know if it can help

According to "the internet" e.g. here, 364.51 seems to have a bunch of bugs in it... Try reverting to an older more stable driver and trying again.

[herotom99]

I have already tried to rollback the driver to the previous but it doesn't work, I will try to use a "more" old driver.

[herotom99]

I have installed different drivers:
-362.00
-361.91
-358.50
then come back to 364.51 but it doesn't works.

I have downloaded OpenGL Extensions Viewer, make a complete test and there is no problem to create a context 4.4. It's very stange. I think it's not a problem of driver because everything else works...

You never mentioned what version of SFML you are using... a lot of these kinds of bugs have been fixed by now.

[herotom99]

SFML 2.3.2 Visual Studio 2013 32bits
I think it's the last version

[herotom99]

Another thing, I have tried the OpenGL example in the "examples" file.
It works and I tried to recreate the program with the "OpenGL.cpp". It compiled
but it crashs when I launch the program.
It spams "Failed to activate the window's context"

That means that the error has something to do with how you build your code. Double-check everything again. Don't assume that something isn't a problem just because it does not lead to any obvious effects.

I found the problem !

It was about my opengl32.dll
I used an old .dll because it was the same on my laptop.
I took the opengl32.dll in C:/Windows/system32/ and now it work !

I have also tried to use the "new" .dll on my laptop to be sure that I can switch between two pc without having to change the .dll and it looks to works correctly.

Thanks a lot for your help and your time !
You are awesome (first meaning)  !

Don't copy the OpenGL DLL. It gets installed by your driver and will automatically be available on your system...
