Hi Sebastian,

great, that's it. I love bugs that are already fixed.

Thank you!

Cheers,
Johannes

Re: [osg-users] "Cross-compiling" from XP64 for Windows 7 64: Crashing when rendering with shaders

2013-01-11 Thread Sebastian Messerschmidt 

Hi Johannes,

IIRC there was a bug in the 3.1.2 int osgProgram.cpp in Line 772 which 
can be fixed like this:


if (_extensions->isShaderAtomicCounterSupported())
->
if (_extensions->isShaderAtomicCounterSupported() && 
!atomicCounterMap.empty())



cheers
Sebastian

Thank you!

If you turn up the OSG notification level to DEBUG_FP, do you get any
useful information before/at the crash?

Yes, Alphapixel only.

You're just using the AlphaPixel 3rdparty library binaries then?

Hi,

Jesus. I'm now compiling any OSG release from 3.0.1 to trunk to see where the 
error occurs first.

Hopefully tomorrow I'll find something.

Meanwhile I'd be glad for recommendations...

Thank you!

Re: [osg-users] "Cross-compiling" from XP64 for Windows 7 64: Crashing when rendering with shaders

2013-01-10 Thread Johannes Scholz 
Hi,

I just tried the following:

Build a naked OSG-3.1.2 using VS2008 Express with Alphapixel binaries on Xp-64
Ran it on Win7-64: osgviewer test_geometry.osg -> Crash

Build a naked OSG-3.0.1 using VS2008 Express with Alphapixel binaries on Xp-64
Ran it on Win7-64: osgviewer test_geometry.osg -> Renders as expected.

So what might be the difference?

Thank you!

Cheers,
Johannes
