Platform Linux 16-04, no message error on compile!

But => ldd /home/mbariou/.local/lib/python3.6/site-packages/py3d.cpython-36m-x86_64-linux-gnu.so
linux-vdso.so.1 => (0x00007fffd17fc000)
libVisualization.so => not found
libIO.so => not found
libCore.so => not found
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f516808d000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f5167e77000)

@marcel-bariou
Could you be more specific about the steps that led to this issue?
I have some limited experience with Open3D building/installing/importing, maybe I can help.

A possible hack: I personally haven't tried the shared libraries path. Seems to work when I build the static libraries for Open3D. Not sure if that is an option for you.

The "not found" libraries do not exist in the ld search path. See e.g. the answers to this question: https://unix.stackexchange.com/questions/22926/where-do-executables-look-for-shared-objects-at-runtime

hello ! @jakobwilm & takanokage Thanks for your interest. I succeed I tell you !
I met the trouble when, after compile and install, I have done : import py3d in Python, libVisualizaition.so and two other libraries were not found by py3d.cpython-36m-x86_64-linux-gnu.so
In fact the missing libraries were not in the lib path, because they were not installed. they were present in the build directory. So I place them manually in /usr/local/lib/open3d, I indicate the path /usr/local/lib/open3d in /etc/ld.so.conf.d/open3d.conf, I run ldconfig and eveything was OK! Something is missing in the install directives.
