2 years ago I managed to get it compiled through the guide using one exception: i did call "util/install_deps_ubuntu.sh" before running cmake.
I also followed the guide you found: http://www.open3d.org/docs/release/tutorial/visualization/headless_rendering.html
Precontidtions I am using Ubuntu 20.04 LTS as WSL and would like to render 3D objects (.stl/.obj files) in order to automatically generate pictures of these objects.
Basically the issue is the same as #940 but I will summarize it shortly.
I performed the following steps: Follow the instructions from here except that I did not use a virtual environment.
For OSMesa, I tried two different approaches: 1.) Follow the instruction from the link above 2.) Follow the instructions from here except that I used BUILD_GLEW=OFF and DBUILD_GLFW=OFF
Both approaches resulted in
[Open3D ERROR] GLFW Error: X11: The DISPLAY environment variable is missingwhen trying to execute the example from headless_rendering.pyIt seems to me that the 2 compiler flags does not have any impact. As I cannot find any solution for this problem I am writing this issue in hopes that someone could explain step by step what needs to be done on a clean OS in order to get this thing working.
My output from GLInfo

[Open3D DEBUG] GL_SHADING_LANGUAGE_VERSION: 1.40As an user who just wants to use the library for rendering I spent a lot of time figuring out how to install missing dependencies etc. . It would be nice to get an installation script that handles all of these things.
