Hi Alessandro:

   I build omegalib 16 with omegaOsg on windows with vs2013, when it build osgBullet, the errors is as bloew:

It like that vs can't find osg::Node::asCamera(void) and osg::Node::asCamera(void)const's definition。

But in osg::Node header file:

        virtual Camera* asCamera() { return 0; }

        virtual const Camera* asCamera() const { return 0; }

the definition is in header file.

And when I build omegaOsg whit osg3.4.0, OsgDebugOverlay.cpp:125

foreach(osgUtil::RenderStage::RenderStageOrderPair rsop, stage->getPreRenderList())

osgUtil::RenderStage not have member getPreRenderList.

Help Help Help.

Thank you!

Hi Alessandro:

   Today I rebuild all omega with osg, and no errors anymore.

And is there any omega with osgearth demoes?

Thank you!

There is a python example here: https://github.com/omega-hub/omegaOsgEarth/tree/master/examples (you need to install the omegaOsgEarth module)

Note that this code is pretty old and afaik nobody is maintaining osgEarth support at this time.. it might still work but can't say for sure.
