GLEW initialize error about celestia HOT 6 CLOSED

Do you link Qt libs statically so it starts without Qt installed?
I'd check whether that system has proper OpenGL subsystem, afaik default video drivers installed by Windows might lack OpenGL support.

@375gnu I'm not doing anything, just doing the compilation of celestia.pro in QT Creator. Then I place the executable file in the Celestia 1.6.1 folder and add the necessary dll files: libintl_x86.dll, Qt5Core.dll, Qt5Gui.dll, Qt5Multimedia.dll, Qt5Network.dll, Qt5OpenGL.dll, Qt5Widgets.dll, platforms/qminimal.dll, platforms/qoffscreen.dll, platforms/qwindows.dll

On two computers where I tried to start Celestia 1.7.0 there are no problems with OpenGL, because Celestia 1.6.1 works great.

Now found out that Celestia 1.7.0 works on NVIDIA and other GPU, but does not work on integrated Intel GPUs.
Checked on the following:

Vendor: Intel
Renderer: Intel(R) HD Graphics
Version: 3.1.0 - Build 9.17.10.4459
GLSL version: 1.40 - Intel Build 9.17.10.4459
Max simultaneous textures: 8
Max texture size: 8192
Point size range: 1.000000 - 20.000000

and

Vendor: Intel
Renderer: Intel(R) HD Graphics 3000
Version: 3.1.0 - Build 9.17.10.4459
GLSL version: 1.40 - Intel Build 9.17.10.4459
Max simultaneous textures: 8
Max texture size: 8192
Point size range: 1.000000 - 20.000000

It is important that on both these computers Celestia 1.6.1 works perfectly.

You might be missing some dynamically loadable opengl modules for qt5. https://doc.qt.io/qt-5/windows-requirements.html is a good start to get info about how to run opengl with qt5 and windows.

Any dlls specified in this document, I already tried to add in Celestia folder (with compiled execulable), but nothing helped.
It will be hard for me to understand the entire document, to translate it into my native language for a long time.

from celestia.

you should use tools provided by qt to copy required dll instead of doing this manually.
