Issue Description

Hello, I’m trying to install librealsense according to https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md in conjuction with https://github.com/IntelRealSense/librealsense/issues/4271.

When I run ./scripts/patch-arch.sh I get the following output:

It seems two patches failed to apply, therefore causing the compilation to fail.

So it finally works! 😃 To recapitulate what I just did to make it work for others in the future:

a) I followed the steps to build pyrealsense2 wrapper from source: https://github.com/IntelRealSense/librealsense/tree/master/wrappers/python. I needed to call cmake with python bindings and then make -j4 which created pyrealsense2 library files (.so files) in build/wrappers/python folder.

b) Now, one has to make sure Python knows about these libraries. Because I use conda, there is, I believe, no reason to change PYTHONPATH, since conda does not use it. There are many ways to achieve this as described here https://stackoverflow.com/questions/37006114/anaconda-permanently-include-external-packages-like-in-pythonpath. I executed conda develop build/wrappers/python/ which created .pth file in anaconda3/envs/ibt/lib/python3.7/site-packages folder.

From now on, I can import pyrealsense2 as rs and it works just fine.

Thank you @MartyG-RealSense for all the help! 😃
