Hi,
I will try later with the latest svn.
I have an older version (8504) and your posted command line for
stereomatch works on Linux here:
The top right is white, but the top left shows the disparity image.
osgmultiplerendertargets without params should display a light yellow
square.
I also post my warnings, they are similar to yours, you do not need a
specific enable for sampler2DRect, OSG does this.
It seems something is up with FBO and multiple targets. Can you check if
osgprerender works properly?

I've compiled OSG from svn HEAD (revision 8952)on Windows XP, but
osgstereomatch isn't working. I have an NVIDIA 8800 card; I tried driver
version 169 and 175 with the same results.
I'm using OpenSceneGraph-Data from svn HEAD (revision 8952) as well.
When I run
osgstereomatch --left Images/dog_left_eye.jpg --right
Images/dog_right_eye.jpg --min 0 --max 31 --window 9 --single
I see the two dog images with a flat red rectangle above them on the
left and a flat white rectangle above on the right. Isn't this example
supposed to show the pixel difference between these images?
I tried without '--single' as well, and the only difference is the red
rectangle is blue.
The only sign of something going wrong are warnings are printed from
compiling the shaders with OSG_NOTIFY_LEVEL=DEBUG_FP (see attached log).
Also, there was an additional warning that said sampler2DRect couldn't
be used without adding the following to the shaders:
#extension GL_ARB_texture_rectangle : enable
But adding that didn't resolve the problem.
On a possibly related note, osgstereoimage doesn't display anything, and
osgmultiplerendertargets only displays a blue rectangle (which I'm not
sure is correct).
Is anyone else having similar problems? Any suggestions?
