[vtkusers] 'Undefined Reference' Error Message

[Mathieu Malaterre]

Jeremy,

	What cmakelists file do you use to compile this ?
	By any chance do you have static lib of VTK somewhere in a path that 
can be found by g++ ? Compiling an example with vtk static libs 
*require* the use of cmake otherwise it's too much a trouble.

HTH

This one works for me:

FIND_PACKAGE(VTK)
IF (VTK_FOUND)
   INCLUDE (${VTK_USE_FILE})
ENDIF (VTK_FOUND)

ADD_EXECUTABLE(translator translator.cpp )
TARGET_LINK_LIBRARIES (translator
   vtkParallel
)

$ cat translator.cpp 

#include "vtkMPIController.h"
#include "vtkConeSource.h"

int main()
{
   vtkMPIController::New()->Delete();
   vtkConeSource::New()->Delete();
   return 0;
}
