Hi Sebastian,

One thing which is definitely an error:
You are never setting the type of the shaders.
Thank your for pointing that out but I'm sure that's not the problem. I'm using
osgDB::readShaderFile to load the shaders sources from disk. The function uses
osgDB::Registry to to load the appropriate ReaderWriter plugin for the filename
extension, and this plugin then handles the request to read the specified file.
This sets the type of the shaders automatically based on the files' extensions
(which are .vert, .geom, and .frag in my case).

Ok. I'd usually don't rely on something like this ;-)
The other problem is with your shaders:
You are using GL3 shaders without compatibility mode, hence there might
be a missing binding.
try
#version 330 compatibility
and use gl_Vertex in your vertex shader.
Your simple geometry shader lacks a EndPrimitive too.
Apart from this I did not manage to get your geometry shader to output
anything useful, so maybe there is some error in here too.
I'd start by constructing a single triangle to see if the data is passed
correctly and then add the rest.
Cheers
Sebastian.
Cheers,
Ahmed
