Irrlicht Engine

Hi..... I am trying to use ImGui with Irrlicht (ver. 1.84) but getting undefined reference error (using codeblock+mingw64 ) as shown here

Can anyone tell me how can I get this work.

Trying in this way......but still not working......just a corner view of model with no movement/zoom or any effects of mouse with/without CTRL button     ICameraSceneNode* Camera_2 = smgr->addCameraSceneNode();     //Camera_2->setPosition(core::vector3df(0,0,0));     //Camera_2->setTarget(core::vect...

is there any simple example or any example of using Custom Maya Camera Animator......
