(25+dev-SNAPSHOT): FXGL-ShaderExample does not run for me on Windows 11 with an exception "Cannot open library..."

[steinmartin]

After cloning the https://github.com/AlmasB/FXGL-ShaderExample on a box with Windows 11 x86_64,
I get the following exception:

18:35:34.352 [FFCThread-0              ] WARN  ForeignFunctionCalle - FFCThread task failed

The JDK versions I tried were:

• liberica-full-23.0.1
• temurin-23.0.1
• openjdk-23.0.1

The fxgl-shaderlib.dll is present in the cache.

The full startup log is:

Thanks for this. Could you also confirm that "SDL2.dll" and "glew32.dll" are in the ...\cache\fxgl-21\gl\ directory?

I've tried running the demo with the same version 28.12.2024 08.41 with a cleared cache and it seems fine. So, my initial thought is there might be some .dlls (opengl32.dll or similar) not being loaded properly in the above case. Are you running in a virtual environment by any chance?

[steinmartin]

Both "SDL2.dll " and "glew32.dll" are in the ...\cache\fxgl-21\gl\ directory. I cleared cache ones and they returned correctly.

I am not on a virtual environment:

Edition Windows 11 Home Version 23H2 Installed on ‎12/‎28/‎2024 OS build 22631.4602 .... Experience Windows Feature Experience Pack 1000.22700.1055.0

I checked for the opengl32.dll and it has a size of 933,888 bytes. If you have further ideas it would be my pleasure to help.

[AlmasB]

Thank you for the offer.

It loads them in the order of SDL2, glew32, fxgl-shaderlib, so I assume the first two (and their deps) are loaded correctly. The last one has these unique deps:

MSVCP140D.dll => /c/Windows/SYSTEM32/MSVCP140D.dll
VCRUNTIME140_1D.dll => /c/Windows/SYSTEM32/VCRUNTIME140_1D.dll
VCRUNTIME140D.dll => /c/Windows/SYSTEM32/VCRUNTIME140D.dll
ucrtbased.dll => /c/Windows/SYSTEM32/ucrtbased.dll

Could you check these please, and list all of the missing ones (if any?). If this is the cause, I might need to link downloads via Microsoft VC++ Redist.

[steinmartin]

MSVCP140D.dll not present:

VCRUNTIME140_1D.dll and VCRUNTIME140D.dll not present:

ucrtbased.dll not present:

Thanks for hanging on...

Have you solved this problem, brother? I encountered the same problem and downloaded the above four DLL files, which were placed in the System32 folder, but the problem still hasn't been resolved
