[osg-users] [osgPlugins] Problems with dae plugin

[Nikita Petrov]

Thanks for suggestion, I've checked for DLLs and strangely some were not loaded from PATH variable paths.
I copied the needed ones to OSG bin and now it launches.

But still dae is not loading. It throws an exception on the second "if" of D:\OSG\base\sources\collada-dom\dom\src\dae\daeIOPluginCommon.cpp:


Code:

  if (parentElement == NULL) {
          // This is the root element. Check the COLLADA version.
          daeURI *xmlns = (daeURI*)(element->getMeta()->getMetaAttribute( "xmlns" )->getWritableMemory( element ));
          if ( strcmp( xmlns->getURI(), element->getDAE()->getColladaNamespace() ) != 0 ) {
              // Invalid COLLADA version
              daeErrorHandler::get()->handleError("Trying to load an invalid COLLADA version for this DOM build!");
              return NULL;
          }
      }



I will also attach screenshot with this exception and a call stack.

I use this string path as an argument to osgviewer.exe: D:/OSG/123/test.dae.

I guess that this question is not directly connected with OSG (because error occurs in collada-dom library), but maybe someone could confirm this error with latest sources or show me what am I doing wrong.
