[Flightgear-devel] Shaders: Issue 294 not accepted?

[HB-GRAL <fli...@sa...>]

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
