Error: VALIDATE_PIPELINEDESC_ATTR_SEMANTICS: D3D11 missing vertex attribute semantics in shader

[funatsufumiya]

Errors happening when running run-passes on Windows 11, on current main (3250a6a). Is this related to #31 ?

It could be - does the sprite-animation example exhibit the same error?

[funatsufumiya]

Yes. probably the same one. (FYI, this is not happening on macOS Metal.)

Pushed a potential fix for the D3D11 shaders loaded via YAML error:
VALIDATE_PIPELINEDESC_ATTR_SEMANTICS: D3D11 missing vertex attribute semantics in shader

Looks like Sokol expects there to be an attrs block in the Shader descriptor that I wasn't populating. That data does exist in the YAML reflection file for the shader, so I'm populating it now.

f6383ce

I'm running into a very strange error on Windows where the Yaml parser is exploding on the first token and first line with an 'index out of bounds' error, so I'm not able to test it currently. For the time being, I removed the YAML shader loading from the sprite-animation example to unblock the stresstest and passes examples until I can make a separate example just for this feature.

Thank you for your prompt action!

I tried current latest ( 2a38275 ). Test results are:

Is the error on Ubuntu still this one?

GL_VERTEX_ATTRIBUTE_NOT_FOUND_IN_SHADER: vertex attribute not found in shader (gl)

[funatsufumiya]

Seems so. I tried once with recompiling shaders (zig run shaders), error logs not changed: passes-log-ubuntu.txt

By the way, using latest sokol-tools-bin, some errors shown kind of like error: 'binding' : uniform/buffer blocks require layout(binding=X) (but error of default-mesh.glsl.zig seems different ). This may be related. (This errors are the same on Win/Mac/Linux.)

shaders-error-log-ubuntu.txt

I could recompile shaders using old (?) sokol-tools-bin, which I already installed before. But I don't know which version I'm using (on old version) because the folder wasn't git controlled...

Could you try pulling and building this commit, and seeing if it fixes thepasses and meshes examples for you?

Ah, sorry. Looks like this was a regression as this branch was not done on the latest main. I've updated the bugfix/vert_attrib_not_found_gl branch and the latest CL for it is now:
d666383a759bb0f7513893756e7ad55dea9d0502

Looking at the logs, it doesn't look like this will fix all of the examples still though.

Okay, this definitely looks like this issue in Sokol, where OpenGL can optimize away unused shader attributes:
floooh/sokol#940

These shaders would probably run just fine, but Sokol is doing a bunch of its own validation that is getting in the way. The only way to really fix this right now will be to use the tangents and normals in the default shaders in a way that keeps them from getting optimized away. Will keep working on a fix.
