error during build

[Skamiz]

Hello, I am trying to get this running on Ubuntu according to the guide in the readme. But the last step 'make -C build' is interrupted by this error:
`
[ 1%] Generating sprv/ssao_compose_rq.frag.sprv
/home/daren/github/OpenGothic/shader/ssao_compose.frag
WARNING: /home/daren/github/OpenGothic/shader/ssao_compose.frag:5: '#extension' : extension not supported: GL_EXT_ray_query
ERROR: /home/daren/github/OpenGothic/shader/ssao_compose.frag:20: '' : syntax error, unexpected IDENTIFIER, expecting LEFT_BRACE or COMMA or SEMICOLON
ERROR: 1 compilation errors. No code generated.

ERROR: Linking fragment stage: Missing entry point: Each stage requires one entry point
`
It's my understanding that I need to update some graphics library to make 'GL_EXT_ray_query' available. But I have no clue how to go about that.
Or maybe I am completely off.

Anyway, any help would be appreciated.

Hi, @Skamiz !

Seems like your shader compiler is outdated. What is your version of glslangValidator?

[Skamiz]

daren@nuc01:~/github/OpenGothic$ glslangValidator -v
Glslang Version: 8.13.3559
ESSL Version: OpenGL ES GLSL 3.20 glslang Khronos. 13.3559
GLSL Version: 4.60 glslang Khronos. 13.3559
SPIR-V Version 0x00010400, Revision 1
GLSL.std.450 Version 100, Revision 1
Khronos Tool ID 8
SPIR-V Generator Version 8
GL_KHR_vulkan_glsl version 100
ARB_GL_gl_spirv version 100

I hope one of these lines answers your question, because I have little Idea what I am doing.

seems to working now, many thanks

finished compiling and figured out the command to start the game. it runs at 8 - 20 fps, but that's on me for not having a graphics card, nonetheless is there a way to disable the dynamic shadows?

And also thank you a lot for letting me relive this piece of nostalgia. I don't think I had a finished G2 run in which I didn't cheat, so now I have the opportunity to correct that.

You can set shadowResolution to zero, by modifying render.h - that for shadowmaps
Settings -> Game -> Cloud Shadows , to toggle SSAO effect

works, thank you :)
