Hi guys,<br><br>Trying to compile one of my programs I got the following error messages<br><br>/usr/local/include/InsightToolkit/Common/itkVector.h:68: error: no type named ‘RealType’ in ‘class itk::NumericTraits&lt;itk::Image&lt;short int, 3u&gt; &gt;’<br>
<br>After that, I update my itk source to cvs head and clean out everything with a &quot;make clean&quot;. Then I run ccmake to generate a new CMakeLists.txt.<br><br>After all this, I go the following error when trying to compile itk<br>
