That path is odd. It doesn’t seem to be a valid include path. I’d expect something like `/usr/local/include/vtk-9.0` .

Maybe it’s better to remove the symlink. My bad.

Can it be that the rendering libraries are not even build when installing via VTK?

Well, you said you built VTK successfully. Did you do a `make install` after building?

Yes I did do that. `sudo make install -j8`

Where is the `vtkm/rendering/Actor.h` file? Do a `find /usr -name "*Actor.h"`.

This would be the result of that:

```
The last line is from the standalone installation I tried. But the standalone doesn’t work for me because I need certain includes from VTK.

So, how is VTKm install dir configured in the CMake of your program?

To /usr/local/include/vtk-9.0/vtkm

Hence you need to set it to `/usr/local/include/vtkm-1.5`.

Notice that I asked for the **install dir** , not where VTKm’s `CMakeLists.txt` is.

Yes I understood that, thank you for your help up until now. The problem is, when I set up a minimal project which requires both VTK and VTKm the includes work but my program crashes.
Example:
CMake:
VTK\_DIR = `/usr/local/lib/cmake/vtk-9.0`
VTKm\_DIR = `/usr/local/lib/cmake/vtkm-1.5`
main.cpp:
```
#include
#include
#include
#include
int main(int argc, char *argv[]) {
vtkm::cont::Initialize();
vtkm::io::reader::VTKDataSetReader reader("/home/david/Documents/magField.vtk");
vtkm::cont::DataSet inData = reader.ReadDataSet();
vtkm::filter::Contour contour;
contour.SetActiveField("vec");
contour.SetIsoValue(-1, 1);
vtkm::cont::DataSet outData = contour.Execute(inData);
vtkm::rendering::Actor actor(
outData.GetCellSet(),
outData.GetCoordinateSystem(),
outData.GetField("vec")
);
return 0;
}
```
Output is following:
```
**david@david-mint** : **~/Documents/minimal/bin** $ ./minimal **Loguru caught a signal: SIGSEGV** Segmentation fault (core dumped)
```
That’s why I tried installing VTKm via VTK by enabling the CMake options to include VTKm. I thought it might help preventing a SEGV, but when I do that, and then therefore build with `/usr/local/lib/cmake/vtk-9.0/vtkm` instead of `/usr/local/lib/cmake/vtkm-1.5` the compiler fails to include actor.h. What I can’t get my head around is why only this functions when I use vtkm::filter::Contour but comment out the actor.
May it be woth Converting the DataSet back to VTK? How hard could it be to convert the result of contour.Execute(inData) to a VTK DataSet instead of VTKm?
Thank you for your time,
David

Please, compile this and run. Does it crash?
```auto
#include
#include
#include
#include
int main(int argc, char *argv[]) {
return 0;
}
