Hi Mike,
The errors are obviously OpenGL ES related. IIRC there are no built-in
uniforms for material/lights. So maybe the ES path is not yet complete
regarding shaders.
Is the shader maybe inside your osgt file itself? I don't remember if
there is some kind of automagic shader generation to emulate fixed
function path ...
cheers

Hi
right got complete build, Xcode 4.6, SDK 6.1, OSG 3.2 branch (built with
OpenGLES 2.0 only). All links and runs, it loads .osgt files, but I get errors
at runtime when shaders get compiled (see below). I'm not adding the shaders,
it seems to be the default ones OSG adds. The code is basically the same as
osgviewerIPhone…
any ideas as to why it may not work?
Cheers,
Mike

Does the OSG-3.2 branch compile with osgEarth? If so you could try this as it
contains a few of the build fixes that aren't in OSG-3.2.0.
I'll have to try. I'm building OSG 3.2.0 (tag)
