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
