My project can work on both Windows and Linux. According to my project, I only need a solution for any of the following 2 problems:

  1. Building python3 wrapper on Windows10

  2. Building python2 or python3 wrapper on Ubuntu16.04

    I tried many methods, and my problems are as below:

  1. Building python3 wrapper on Windows10 As you say, the only way to build python3 wrapper on Windows is to use CMake and build from source. I guess that building python2 wrapper on Linux may be easier, so I give up Windows solution.

  2. Building python2 or python3 wrapper on Ubuntu16.04 I followed the tutorial for Linux . I run realsense-viewer and launched the SR300 GUI successfully. Then I run sudo apt-get install librealsense2-dev and sudo apt-get install librealsense2-dbg successfully. However, when I wanted to run g++ -std=c++11 filename.cpp -lrealsense2, I did not know where the "filename.cpp" is . So I skipped that step. Then I browsed python wrapper tutorial for Linux and found I need to install CMake. Is there any method to build python wrapper without using CMake? I want to copy pyrealsense2.pyd and realsense2.dll to my program. But at this moment, I cannot find pyrealsense2.pyd and realsense2.dll in my system. Did I have some step missing?

    After these attempts, I found another tutorial pyrealsense 2.2, and pray this can be an easy python wrapper building tool. But pip install pyrealsense run into an error:

Could you please help me?

Thank you very much!! I followed your guide, but faced some error when make -j4:

I use 'make -j4 -i' to ignore the errors, and get the following result:

Then I found librealsense2.so in the build file, and its color is light blue in the ubuntu common line, which means symbolic link file. Then I run cdll.LoadLibrary('librealsense2.so') in python IDE successfully. But I do not know how to use this file in python. could you please tell me how to use this 'librealsense2.so' to capture images in python?

Then I go to ./wrappers/python, and found pyrealsense2.cpython-35m-x86_64-linux-gnu.so, but its color is red, which means compressed file. I run cdll.LoadLibrary('pyrealsense2.cpython-35m-x86_64-linux-gnu.so') in python IDE and get error:

OSError: pybackend2.cpython-35m-x86_64-linux-gnu.so: cannot open shared object file: No such file or directory

I have written the path in /etc/ld.so.conf but the error still occur. I wonder whether the file is complied successfully or not?
