[Paraview-developers] WG: Paraview with python problem

Thu Dec 19 00:48:31 EST 2013

Uh, now i am close in debugging:

It closes in vtkPythonInterpreter::Initialize(); at vtkMatplotlibMathTextUtilities.cxx at 115

I FOUND SOMETHING WITH PYTHON; YEAH

Now I debugged further deeper:

Inside bool vtkPythonInterpreter::Initialize(int initsigs /*=0*/) of vtkPythonInterpreter.cxx the Py_InitializeEx(initsigs); call closes my app, so there is something wrong with my python... I do not have python in debug mode compiled so I am stopping debugging here, but now I know where to look....

Hi again,

so now i made a completely new empty build directory and i compiled it in 32 and 64 bit in release and debug mode (whereby I only had release libs of python) and all 4 variants close like before after applying any source...... 
So I can really say that there is no dll/lib mismatch....

Which python lib are you exactly using, I use one of my colleges which works for them. May there is something wrong inside them....

Best regards,
Yours tired Gerald.....

Try a clean build :). I am sure that will resolve this issue (well, 90% sure). Nothing should close the application without exceptions or errors, unless the libraries are mismatched -- which could happen in case of a broken build. I'd strongly suggest doing a clean build.

If you cannot step, I think it's a problem with mismatched/improperly built libraries or something. If the call stack starts making no sense, it's definitely that, and I'd recommend a clean build -- start with an empty binary directory.
