This version of vtk was the nightly build from yesterday . The following code was working before without problems . <div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>char *buffer;</div><div>
<span class="Apple-tab-span" style="white-space:pre"> </span>buffer = _getcwd(NULL,0);</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>QString path(buffer);</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>QString filename = QFileDialog::getOpenFileName(this,"LoadVTk Files",path, "Txt (*.vtk)");</div>
<div> vtkPolyDataReader *slcreader = vtkPolyDataReader::New();</div><div> slcreader->SetFileName(filename.toStdString().c_str());</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span> std::string wq = "image.stl";</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span> // wq.replace(wq.size()-3,3,"stl");</div><div><span class="Apple-tab-span" style="white-space:pre"> </span> // cout << wq << endl;</div>
<div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span> vtkSTLWriter *stlwriter = vtkSTLWriter::New();</div><div><span class="Apple-tab-span" style="white-space:pre"> </span> stlwriter->SetFileName(wq.c_str());</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span> stlwriter->SetInputConnection(slcreader->GetOutputPort());</div><div><span class="Apple-tab-span" style="white-space:pre"> </span> stlwriter->Update();</div>
<div><br></div><div>That is all i have in the app . I changed the stlwriter->SetInput to stlwriter->SetInputConnection() because the former function does not link .</div><div><br></div><div><br></div><div><br><div><div class="gmail_quote">

What version of vtk? Also can you post a small, compilable example<br>
that illustrates the error? Looks like a programming bug on your part.<br>
