[openvrml-develop] [Fwd: [www-vrml] Problems with VRML viewers under Linux]

[Thomas F. <tf...@ro...>]

The following message was posted to www-vrml last week from a guy trying 
to get his world to load in ANY browser under Linux. His results are 
posted below with OpenVRML 0.11.2

I've tried his world (attached to this mail) with the latest version of 
CVS and get the following assertion failure on load

../../../../src/openvrml/OpenVRML/nodeptr.h:94: OpenVRML::Node* 
OpenVRML::NodePtr::operator->() const: Assertion `this->countPtr' failed.

 with the following stack trace.

in OpenVRML::VrmlScene::load() at VrmlScene.cpp:286
in OpenVRML::VrmlScene::replaceWorld() at node.ptr.h:93
in OpenVRML::ProtoNode::addToScene() at proto.cpp:292
in OpenVRML::ProtoNode::instantiate() at proto.cpp:188
in OpenVRML::VrmlNamespace::cloneNodes() at VrmlNamespace.cpp:246
in () at VrmlNamespace.cpp:724
in OpenVRML::NodeTransform::accept() at vrml97node.cpp:9238
in () at nodeptr.h:99
in () at VrmlNamespace.cpp:724
in OpenVRML::NodeCollision::accept() at vrml97node.cpp:1519
in () at nodeptr.h:93
in OpenVRML::NodeGroup::setChildren() at vrml97node.cpp:3632



This world loads fine in all the big browsers on Windows. Anyone have 
any insight as to what's going wrong here?

Later,
Tom

Hello,

I just got back to my Linux box and tried to install a VRML viewer to 
look at my animation, and am having trouble getting a browser to display 
the attached file RSA.25-1.0.wrl (there are PROTOs defined in the other 
attached file). The files work just fine under all the Windows browsers 
I've tried. For example, here are the errors I get:

FreeWRL (installation was long but simple):
Invalid field 'set_scale' for node 'Transform'

OpenVRML (installation was a pain due to SpiderMonkey, which is 
installed on my machine under Mozilla, and is almost impossible to 
install standalone. Had to tinker with configure file to make it and use 
the right libmozjs and header files):
lookat: VrmlNamespace.cpp:1067: void 
{unnamed}::NodeRouteCopyVisitor::copyRoutesFromNode (VrmlNode &): 
Assertion `fromNode' failed.
Aborted (core dumped)

Both of these work with other (simpler) VRML models I used for testing!

Xj3D browser not yet installed due to painful installation 
procedure...Clearer and shorter instructions, rpm's, and other widgets 
would be most welcome :)

Could someone that has VRML under Linux running please try and see if 
they can get the attached file to work and let me know.

Thank you,
Aleksandar
