Hi list,<br><br>I have built and installed the 5.4.2 release of VTK from source on Ubuntu 9.10, with Python wrappings (not Java or Tcl), and had some difficulty getting them recognized by python (2.6.4), namely: <br><br>>>> from vtk import *<br>
Traceback (most recent call last):<br> File "<stdin>", line 1, in <module><br> File "/usr/local/lib/python2.6/dist-packages/VTK-5.4.2-py2.6.egg/vtk/__init__.py", line 41, in <module><br>
from common import *<br> File "/usr/local/lib/python2.6/dist-packages/VTK-5.4.2-py2.6.egg/vtk/common.py", line 7, in <module><br> from libvtkCommonPython import *<br>ImportError: libvtkCommonPythonD.so.5.4: cannot open shared object file: No such file or directory<br>
<br><br>My build was a typical out-of-source one:<br><code>$ ls -d VTK<br>
VTK/<br>
$ mkdir build<br>
$ cd build<br>
$ ccmake ../VTK</code><code><br>
$ make -j 3</code><code><br>
$ sudo make install</code><br><br><br>As far as I can tell, the python egg was properly installed in /usr/local/lib/python2.6/dist-packages/VTK-5.4.2-py2.6.egg<br>And the rest of VTK in /usr/local/lib/vtk-5.4<br>
<br><br>According to Wrapping/Python/README.txt this should be enough, but I found that I also needed to add /usr/local/lib/vtk-5.4 to LD_LIBRARY_PATH to get python to find libvtkCommonPythonD.so.5.4<br><br>Unwilling to have to add this to .bash-rc files and so-on, I found that creating a /etc/ld.so.conf.d/vtk.conf containing this path, then running ldconfig seems to work just as well. (as per <a href="http://koobmeej.blogspot.com/2007/04/alternative-to-ldlibrarypath.html">http://koobmeej.blogspot.com/2007/04/alternative-to-ldlibrarypath.html</a>, but using an included file instead of editing the master ld.so.conf file)<br>
<br><br>Should this have been necessary or am I missing something in my build/install?<br>If this seems to be the proper way to finish the install, maybe this should be added to the install target?<br><br>For info, I ran "make test" from the build folder and 97% pass with the /etc/ld.so.conf.d/vtk.conf entry, compared to 3% without. Results with the entry below:<br>
