[vtkusers] unable to run example/tutorial code Cone.cxx

[eric lamar]

Dan:
Thanks for the pointer - however, my need is a little different.  I am making a library that uses VTK.   I need to be able to compile this library directly - I need to see on the command line all of the arguments to the compile.  When I compile the first program, titled "Hello World" (http://www.vtk.org/Wiki/VTK/Examples/Cxx/Rendering/Cylinder):
 g++ -g -O0 Cylinder.cxx -I ~/VTK/include/vtk-6.2 -L ~/VTK/lib  -lvtkFiltersSources-6.2 -lvtkRenderingOpenGL-6.2 -lvtkRenderingCore-6.2 -lvtkCommonExecutionModel-6.2 -lvtkCommonCore-6.2
The program compiles without errors or warnings.  However, I get the same segmentation fault with a null pointer when I run the program.  I've also linked against all 117 libraries (rather than just the 5 listed above) without any difference.  Note that when I compile with the default 'Makefile', it works.   I've examined the 'Makefile's that cmake produces to see what it does differently, but I just don't understand what I'm seeing in the 'Makefile's.  What is done differently in the 'Makefile's that I'm not doing on the command line?
Thank you,Eric.

Try using an example and the cmake file from
http://www.vtk.org/Wiki/VTK/Examples/Cxx

Hello!
I am attempting to run VTK 6.2's example/tutorial code Cone.cxx.  It compiles, however I get a segmentation fault.
My environment:  iMac i7 quad coe, oS X 10.10, VTK 6.2

=========================================================================*///// This example creates a polygonal model of a cone, and then renders it to// the screen. It will rotate the cone 360 degrees and then exit. The basic// setup of source -> mapper -> actor -> renderer -> renderwindow is// typical of most VTK programs.//
// First include the required header files for the VTK classes we are using.#include "vtkConeSource.h"#include "vtkPolyDataMapper.h"#include "vtkRenderWindow.h"#include "vtkCamera.h"#include "vtkActor.h"#include "vtkRenderer.h"

  //  // In this example we terminate the pipeline with a mapper process object.  // (Intermediate filters such as vtkShrinkPolyData could be inserted in  // between the source and the mapper.)

  //  // Create an actor to represent the cone. The actor orchestrates rendering  // of the mapper's graphics primitives. An actor also refers to properties  // via a vtkProperty instance, and includes an internal transformation  // matrix. We set this actor's mapper to be coneMapper which we created  // above.  //  vtkActor *coneActor = vtkActor::New();  coneActor->SetMapper( coneMapper );
  //  // Create the Renderer and assign actors to it. A renderer is like a  // viewport. It is part or all of a window on the screen and it is  // responsible for drawing the actors it has.  We also set the background  // color here.  //  vtkRenderer *ren1= vtkRenderer::New();  ren1->AddActor( coneActor );  ren1->SetBackground( 0.1, 0.2, 0.4 );
  //  // Finally we create the render window which will show up on the screen.  // We put our renderer into the render window using AddRenderer. We also  // set the size to be 300 pixels by 300.  //  vtkRenderWindow *renWin = vtkRenderWindow::New();  renWin->AddRenderer( ren1 );  renWin->SetSize( 300, 300 );
  //  // Now we loop over 360 degreeees and render the cone each time.  //  int i;  for (i = 0; i < 360; ++i)    {    // render the image    renWin->Render();    // rotate the active camera by one degree    ren1->GetActiveCamera()->Azimuth( 1 );    }

-----------So, why does the code complain about "no override found ..."?  Why does the 'codeMapper' get assigned NULL?  What am I missing?  What do I need to change?
Thank you,Eric.
