Does skylicht only supports glsl 4.0 ?

[Joilnen]

When I try to run in linux with intel gpu I got this, and black screen

[AtlasFrame] add light - 40x40 - [0]
[AtlasFrame] add camera - 40x40 - [0]
Warning: Low FPS: 1332.000000 tpf, 0.750751 fps

Hello Joilnen.
Do you use the SDL Backend?
And can you tell me what Linux OS which you are using to run?

I tested and run well on Ubuntu - XWindow - glx (not yet test Editor). The Linux still supports OpenGL 4.6
https://github.com/skylicht-lab/skylicht-engine/blob/master/Projects/Irrlicht/Source/CIrrDeviceLinux.cpp

Can you test make sure the CMake Linux is ON (CMakeLists.txt line 71)

if (CMAKE_SYSTEM_NAME STREQUAL Linux)
    set(BUILD_LINUX ON)
    add_definitions(-DLINUX)
endif()

The engine still supports OpenGLES 3.0, but I just test this driver on Android and WebGL Emscripten.
g_device = createDevice(video::EDT_OPENGLES, dimension2d<u32>(width, height), 32, false, false, false, g_mainApp);
You can see: https://github.com/skylicht-lab/skylicht-engine/blob/master/Projects/Template/Platforms/Emscripten/MainWebGL.cpp

Yes SDL Backend and it's arch linux, only a embed intel GPU, but it is able to run irrlicht well.
Tested forcing "set(BUILD_LINUX ON)"
I guess this is not related with device creation, but with shaders, the window is created without crashes.

Ok I found an workaround setting MESA_GL_VERSION_OVERRIDE=3.3
