Glsl emscripten

[axe312ger]

• add glm as dependency so users don't have to grab it on their own
• add some finding i had on another machien to the readme to help others
• fix makefile with our latest findings

[revmischa]

should be a clean target

[axe312ger]

Is there any way to ensure this like a cleanup script?

[revmischa]

i tried making it so all you need is --enable-emscripten now and it infers the others

[revmischa]

is -lvendor needed? that should be in CPPFLAGS or whatever.. -I

[revmischa]

@deltaoscarmike chill?

[deltaoscarmike]

As is, it doesn't work:

• FF displays the page but PM doesn't start (output log is empty) and finally it freeze
• Chrome displays the page, but PM doesn't start (output log is empty)

You've got it working ? What is the status of this branch ?

[revmischa]

No, I never got it to fully run. But it's not a regression either; emscripten doesn't work in glsl now. It just gets a little closer to maybe working now
@axe312ger do you know what the current problem is? is it still GLSL versions?

[deltaoscarmike]

Oops, i've made a mistake while trying to push a commit on this branch, please delete branch PR92.
Oth, i've got it working (sort of), try this patch

[axe312ger]

Thank you, I gonna have a look!

[axe312ger]

Thats my Chrome console output. (It freezes, make sure to open the console first, then navigate to the server running emscripten

I guess the shaders are still broken / using the wrong types. I tried to fix this 2 weeks ago but no, no luck. (Well fixing as of randomly changing values that seem to be related and 🤞 )

Failed to compile shader 'Fragment: blur1'. Error: ERROR: 0:39: 'assign' : cannot convert from 'const int' to 'mediump float'
Failed to compile shader 'Fragment: blur2'. Error: ERROR: 0:30: '-' : wrong operand types - no operation '-' exists that takes a left-hand operand of type 'const int' and a right operand of type 'mediump float' (or there is no acceptable conversion)

I wonder how to add presets to the wasm as well:

[PresetLoader] ENOENT error. The path "/presets" probably does not exist. "man open" for more info.

Thanks for your help 👋

[deltaoscarmike]

WebGL is rather strict concerning implicit casts, this patch will fix blur shaders, re-enable WASM and print root content of the virtual filesystem.
For the preset directory issue, i think this link could be useful on how to embed presets.
My priority is to get a rendering closer to Milkdrop/winamp and that's lot of work 🔧
Good luck

[axe312ger]

It works now!!! Thanks so much @deltaoscarmike

[axe312ger]

I fixed the merge conflicts :)

[axe312ger]

Still need to read into the file system api for emscripten to get the presets running
