Hi all
For upcoming debugging weeks: Please note that issue #294 and #335 are
still valid here with OSX 10.6, ATI 5750, OSG2.9.7. I still get
Warning: detected OpenGL error 'invalid operation' at after
RenderBin::draw(..)
with every plane (i.e. 737-100) where reflect shaders are active.
I don’t know how to get better debugging information with fgfs, and I
apologize, can someone give me a hint again how I can get "human
readable" error output instead of tousands of this lines above, filling
up my log, pointing to nowhere ?
Now all what I can say is what my "shader builder" on OSX says for
reflect and reflect-bum-spec:
---
Validation Failed: Sampler error:
Samplers of different types use the same texture image unit.
- or -
A sampler's texture unit is out of range (greater than max allowed or
negative).
---
Another validation warning with reflect-bump-spec, but this needs only
some small shader clean up I think ;-)
---
Program link results:
WARNING: vertex shader writes varying 'Normal' which is not active.
---
NONE of the other shaders have problems with passing an external shader
validation. Please accept the issue #294 for OSX/ATI now and assign it
to shader core developers if he/she is still around. (I will try to help
to fix it of course).
btw. using 777-200 (see also issue #335) gives me:
---
FRAGMENT glCompileShader "" FAILED
FRAGMENT Shader "" infolog:
ERROR: 0:58: '>=' : wrong operand types no operation '>=' exists that
takes a left-hand operand of type 'uniform float' and a right operand of
type 'const int' (or there is no acceptable conversion)
glLinkProgram "" FAILED
Program "" infolog:
ERROR: One or more attached shaders not successfully compiled
---
I will vote for removing all the shaders in aircrafts soon :-)
Thanks, Yves
