<p>Hi everyone,</p>
<p>I have posted a question already in the Dune support channel, but maybe here in the mailing list are more python experts:</p>
<p><span class="x_x_mx_EventTile_body x_x_markdown-body x_x_translate"></p>
<p>I am currently trying to run a simple Python example in the dune-vtk module, i.e.
<code>dune/python/test/testvtk.py</code>. I have built everything without a user specified venv, using the default that is created in the build directory. To run the code, I use the script
<code>build/run-in-dune-venv.py</code> in my build directory <code>build/</code>. The problem I have is: The JIT compilation step uses an incomplete list of include directories. In particular, the include dirs from dune-vtk are not there. This can be seen in
the <code>compile_commands.json</code> file, which is located in the dune-py directory in the dune-common build directory
<code>build/dune-venv/.cache/dune-py</code>.</p>
<p>The error I get is "fatal error: dune/python/vtk/writer.hh: file or directory not found".</p>
<p>Can anyone tell me how this <code>compile_commands.json</code> file is generated? I am trying to figure out why it does not include all the include directories of the modules involved.</p>
<p>Best, Simon<br>
