</div></div>Where would you put them for a system vtk installation? For both the<br>
python 2 and the python 3 build, by default they are installed into the<br>
site-packages directory. It feels to me that this is a good place to put<br>
them. It's just that the import rules changed for py3k.<br>
<br>
However you are right that both of my proposals would break your<br>
workflow. The only thing which comes to my mind is to separate the<br>
extension into its own (private) package.<br></blockquote><div><br></div><div>I've looked over the guidelines for installing python modules, and it</div><div>seems that your original proposal was correct, i.e. the extension</div><div>modules should be placed in the same dir as the python files, which</div><div>would require either a) a relative import or b) placing the extension</div><div>modules one directory level up (which is messy).</div><div><br></div><div>The relative import breaks things for me when I try to use VTK from</div><div>the build directory (i.e. without doing a make install).</div><div><br></div><div>I have no immediate solution, but I'll think on this if I find any spare</div><div>time over the next couple days...</div><div><br></div><div> - David</div><div><br></div></div></div></div>
