All compiled good
But after launch ./theforceengine only black screen

The issue is most likely the GPU or driver - it is reporting [RenderBackend] OpenGL Device Tier: 1 - so imGui is likely failing to render. This suggests only OpenGL 2.x or earlier is supported, or there is an issue with the GPU driver.

Thanks. Also here i am curious why all working good under Windows 10 at same GPU but video driver is bit newer 342.01 but Linux driver 340.108?

Also geforce 9800 gtx (g92) support OpenGL 3.3
https://www.techpowerup.com/gpu-specs/nvidia-g92.g58

So it all wired things Linux "problems" and no way to investigate them? I mean to fiind reasons why mouselook can freezing under Wine or why i can't see GUI of TFE in native Linux version?

You could try to raise an issue with nvidia (linux-bugs@nvidia.com) about this. It does work with driver 470 on linux; but I guess your gpu is too old for this version now?

Alternatively, ditch the nvidia blob driver and try the mesa noveaou(sp?) driver.

[12sunflowers]

this gpu and driver have no support anymore by nvidia,
340.108 last driver with support my gpu,
nouveau have slower perfofmance compare with proprietary in this case,

why other games running smooth under wine but TFE mouselook have lag spikes?

[mlauss2]

Please paste the output of "glxinfo" somehwere. A 9800gtx should have GL3.3 support, and I remember nvidias drivers supporting GL very well. There must be something else broken, or an extension missing.

@JakeSmarter
flush mesa cache

you can configure the Nvidia device driver to use some other GLSL compiler?

how do this?

try run flathub version

@12sunflowers: care to try this branch? I've added a few debug statements.
https://github.com/mlauss2/TheForceEngine/tree/test1

run cmake with the following compiler flags to get at least some symbols:
CXXFLAGS="-O2 -ggdb3" CFLAGS="-O2 -ggdb3" cmake -DDISABLE_SYSMIDI=ON /path/to/tfe-src

you have apparently no OpenGL support at all (either missing in libSDL2 or on your system).
Can you paste the "glxinfo" or "eglinfo" output somewhere please?

[12sunflowers]

My old gf9800gtx not fully supports all opengl 3.3 extensions
eglinfo.txt
glxinfo.txt

Amazing! You are a wizard! All working good now!) Thanks for magic! Where is was an issue?

[mlauss2]

Great! The 340.xx nvidia driver series is the last that does not support glvnd (which is a method to have multiple libGL.so files on your system if you have e.g. intel igpu + nvidia dgpu and want to do opengl on both), however modern CMake sets it as default (I did as well in the CMakeLists.txt file), which links the binary against "libOpenGL.so" which does exist on your system, but the nvidia driver
cannot work with it. Almost all applications still just open libGL.so which is why the rest worked for you.

I'll prepare a PR.

Thanks for explanations. It's all bit mess for me but very exiting. Can you suggest some reading about all of that stuff? Radeon drivers also use same way as nvidia, i mean GLX or GLVND?

[mlauss2]

Hello @12sunflowers, could you please test lucius' latest tree whether it works for you? Some other changes have gone it, notably one which removed the whole OpenGL stuff from CMakeLists altogether.

Thanks!

[12sunflowers]

@mlauss2
Hello man! Build current master - worked like a charm!) Thanks a lot for bring back us childhood)

[mlauss2]

fixed by #419

Thanks for testing!

[luciusDXL]

It looks like this has been resolved, so closing.
