You can't use the VTK_GRAPHICS_EXPORT macro unless your class is built into the vtkGraphics library itself. Make up your own equivalent macro for your library...<br><br><br><div class="gmail_quote">On Thu, Apr 17, 2008 at 1:36 PM, Renato N.

Hi folks,<br>
<br>
I'm trying to write a simple graphics filter which takes a DataSet, compute something and add a CellData array to the output's DataSet. The structure of the filter is quite the same the vtkElevationFilter, so, I just copied the .cxx and .h and changed some stuffs.<br>
<br>
Here is the my header created from vtkElevationFilter.h: (all files are here <a href="http://www.nacad.ufrj.br/%7Ernelias/transfer/ColorBoundaryRegionsFilter.zip" target="_blank">http://www.nacad.ufrj.br/~rnelias/transfer/ColorBoundaryRegionsFilter.zip</a> )<br>
<br>
//--------------------------------------------------------------<br>
#ifndef __vtkColorBoundaryRegionsFilter_h<br>
#define __vtkColorBoundaryRegionsFilter_h<br>
<br>
#include "vtkDataSetAlgorithm.h"<br>
<br>
class VTK_GRAPHICS_EXPORT vtkColorBoundaryRegionsFilter : public vtkDataSetAlgorithm<br>
{<br>
public:<br>
static vtkColorBoundaryRegionsFilter* New();<br>
vtkTypeRevisionMacro(vtkColorBoundaryRegionsFilter, vtkDataSetAlgorithm);<br>
void PrintSelf(ostream& os, vtkIndent indent);<br>
<br>
protected:<br>
vtkColorBoundaryRegionsFilter();<br>
~vtkColorBoundaryRegionsFilter();<br>
<br>
int RequestData(vtkInformation*,<br>
vtkInformationVector**,<br>
vtkInformationVector*);<br>
<br>
private:<br>
vtkColorBoundaryRegionsFilter(const vtkColorBoundaryRegionsFilter&); // Not implemented.<br>
void operator=(const vtkColorBoundaryRegionsFilter&); // Not implemented.<br>
};<br>
<br>
#endif<br>
//--------------------------------------------------------------<br>
<br>
The filter's algorithm is implemented in the RequestData method. My CMakeLists file is as follows:<br>
<br>
#---------------------------------------------------------------<br>
PROJECT(ColorBoundaryRegionsFilter)<br>
FIND_PACKAGE(VTK REQUIRED)<br>
INCLUDE(${VTK_USE_FILE})<br>
ADD_LIBRARY(ColorBoundaryRegionsFilter vtkColorBoundaryRegionsFilter.cxx)<br>
ADD_EXECUTABLE(test test.cxx vtkColorBoundaryRegionsFilter.cxx)<br>
#---------------------------------------------------------------<br>
<br>
I can have the filter compiled as library, the problem happens when I try to link with the following test program (. The linker gives me a bunch of error messages<br>
<br>
int main() {<br>
vtkColorBoundaryRegionsFilter* br = vtkColorBoundaryRegionsFilter::New();<br>
br-Delete();<br>
}<br>
<br>
Linker error:<br>

<br>
Any idea?<br>
