Ubuntu 20.04 ceres error

[andrewangbl]

I tried to run VINS-fusion on Ubuntu 20.04. As expected, there are a lot of errors when I catkin. I solved the errors related to opencv version by changing the header files. However, now I left with all ceres related errors. I thought it was my ceres solver problem, but I reinstalled ceres solver several times the errors still exists.

Thanks, this is awsome! I am pretty sure the fatal error I encountered is because of ceres. I changed my ceres version from 2.2.0 to 2.1.0. Then with the repo you provided, I catkin successfully! Again, thanks for your help.
