[Opensg-users] Clustering and attributes

Discussion:

Hi all,

I tried to run my application on a cluster and the slaves did not display
the geometry with custom attributes and gave me this in console:

WARNING: attributes given, but support not enabled, please compile with
OSG_ENABLE_OGL_VERTEXT_ATTRIB_FUNCS=ON

I tried to recompile the cluster server with
-DOSG_ENABLE_OGL_VERTEXT_ATTRIB_FUNCS=ON without success, I will now
recompile the client with that flag and then opensg.

Any idea why it runs perfectly on the local application?

Best regards,
Victor

IIRC that is a cmake flag of OpenSG's build system, so I don't think
it'll have an effect if you recompile your application code - this is
not a flag that is passed to the compiler to define a pre-processor
macro on the command line; unfortunately the syntax for setting cmake
variables on the command line looks exactly like it was.

To me it sounds a bit like there are OpenSG builds compiled with
different options in the mix. Can you make sure all machines use
OpenSG builds compiled with the same options?

Cheers,

Hello Carsten,

I compile my server with:

#!/bin/bash
libs="-lOSGBase -lOSGContribTrapezoidalShadowMaps -lOSGCluster
-lOSGDrawable -lOSGEffectGroups -lOSGFileIO -lOSGGroup -lOSGImageFileIO
-lOSGState -lOSGSystem -lOSGUtil -lOSGText -lOSGWindow -lOSGWindowGLUT
-lOSGWindowX -lGLU -lGL -lSM -lICE -lX11 -lXext -lglut -lXmu -lXi
-lboost_system"
libpaths="-L/usr/lib/opensg"

g++ VRServer.cpp $libs $libpaths -o VRServer

Everything on a single local machine, same opensg installation, same
problem :(
I tried compiling OpenSG with OSG_ENABLE_OGL_VERTEXT_ATTRIB_FUNCS=ON and
got:

cmake .. -DOSGBUILD_TESTS=OFF -DOSG_ENABLE_OGL_VERTEXT_ATTRIB_FUNCS=ON

CMake Warning:
Manually-specified variables were not used by the project:

OSG_ENABLE_OGL_VERTEXT_ATTRIB_FUNCS

When I rerun cmake again I don't get that warning but after compiling
OpenSG the problem is still there.

I do this at the beginning of my server:
OSG::preloadSharedObject("OSGBase");
OSG::preloadSharedObject("OSGContribCSMSimplePlugin");
OSG::preloadSharedObject("OSGContribWebInterface");
OSG::preloadSharedObject("OSGGroup");
OSG::preloadSharedObject("OSGUtil");
OSG::preloadSharedObject("OSGCluster");
OSG::preloadSharedObject("OSGContribCSM");
OSG::preloadSharedObject("OSGDrawable");
OSG::preloadSharedObject("OSGImageFileIO");
OSG::preloadSharedObject("OSGWindowGLUT");
OSG::preloadSharedObject("OSGContribBackgroundLoader");
OSG::preloadSharedObject("OSGContribGUI");
OSG::preloadSharedObject("OSGDynamics");
OSG::preloadSharedObject("OSGState");
OSG::preloadSharedObject("OSGWindow");
OSG::preloadSharedObject("OSGContribCgFX");
OSG::preloadSharedObject("OSGContribPLY");
OSG::preloadSharedObject("OSGEffectGroups");
OSG::preloadSharedObject("OSGSystem");
OSG::preloadSharedObject("OSGWindowX");
OSG::preloadSharedObject("OSGContribComputeBase");
OSG::preloadSharedObject("OSGContribTrapezoidalShadowMaps");
OSG::preloadSharedObject("OSGFileIO");
OSG::preloadSharedObject("OSGText");

commenting them did not help..

any ideas where I can continue to investigate?

best regards,
Victor

OSG_ENABLE_OGL_VERTEXT_ATTRIB_FUNCS

yes, it appears that option (together with the code it controlled) was
removed/rewritten in commit fadad10632f50b122fe95e0a0cf50bdda1045a85
(from 2014-07-17).

OpenSG the problem is still there.

If the server is still printing the message about
OSG_ENABLE_OGL_VERTEX_ATTRIB_FUNCS it is definitely using a different
set of OpenSG libraries - the code producing that message was part of
what was rewritten.

Those should not be related, I think.

You could try running with environment variable LD_DEBUG=libs to get the
runtime linker to print information about where it loads libs from - see
man ld.so for other settings.
