update for ubuntu 20

[JessicaBertolasi]

Hi, I'm trying to create a vio tracking using kimera-vio, but actually I'm working with ubuntu 20 on my pc, is it compatible in some way with this project? have you suggestions, in case it isn't, for vio algorithm compatible and similar to this kimera version?
Thank you and best regards

It will work with a couple minor adjustments.

First, if you are building in ROS make sure to apply the focal patch in mesh_rviz_plugins using git apply ubuntu_focal.patch.

If you are building native (without ROS), use opencv 3.4.2 instead of 3.3.1.

I am regularly testing Kimera in 20.04 using this dockerfile, it may be useful as a starting point:

# Use an official Python runtime as a parent image
FROM ubuntu:20.04

LABEL maintainer="mabate@mit.edu"

# To avoid tzdata asking for geographic location...
ENV DEBIAN_FRONTEND=noninteractive

# Set the working directory to /root
ENV DIRPATH /root/
WORKDIR $DIRPATH

Here are some tips that might be helpful if you want to compile Kimera locally:

• Please follow the gtsam version suggested in Kimera-RPGO which is 686e16aaae26c9a4f23d4af7f2d4a504125ec9c3. The commit number shown in Kimera-VIO does NOT work for me;
• ISAMParams is changed and the cacheLinearizedFactors and evaluateNonlinearError are set as default, you may need to comment some of the lines VioBackendParams.h
• If you are using OpenCV 4.X version, you may need to include another viz/viz3d.hpp in visualization related header files

Good luck

Hi, what is the proper way to proceed?
