I decided to port this noise shader from shadertoy (

 and am not compiling in the slab due to variable names, it seems. I'm declaring the variables in the shader, though?

I get these warnings from the max window:

jit.gl.slab: -- START GLSL INFO LOG: fp --

ERROR: 0:104: Use of undeclared identifier 'iResolution'

ERROR: 0:105: Use of undeclared identifier 'uv'

ERROR: 0:105: Use of undeclared identifier 'iResolution'

ERROR: 0:106: Use of undeclared identifier 'uv'

ERROR: 0:107: Use of undeclared identifier 't'

ERROR: 0:108: Use of undeclared identifier 'finalColor'

jit.gl.slab: jit.gl.shader: GLSL program failed to compile.

    //is this perlin? we'll find out after it's working

You are not declaring them, you are only handling the bindings in the xml header.

You need to declare them after the header:

return fract(sin(dot(p, vec2(15.79,81.93)))*45678.9123);

float hash(vec2 p)
{

}


Side note... Since you are in the fragment shader you don't need to declare varyings, only uniforms. Use varyings if you need to pass data from vertex or geom passes.

And it's easier to use the build in states:
