JeVois 1.10.0 Bug reports, full story, part 5 (last for today)

Trying to build jevoisbase-1.10.0 host, using version jevoisbase-1.10.0 in jevoisbase-1.10.0 folder on Ubuntu 16.04 LTS with latest updates.

[  8%] Building CXX object CMakeFiles/jevoisbase.dir/src/Components/EyeTracker/EyeTracker.C.o

It seems that EyeTracker components are sensive to project path :-\
Somewhere here - /home/user/jevoisbase-1.10.0/include/jevoisbase/Components/EyeTracker/EyeTracker.H

#pragma once

#include <jevois/Component/Component.H>
#include <opencv2/core/core.hpp>
#include <jevoisbase/Contrib/cvEyeTracker-1.2.5/ransac_ellipse.h>

OK, let's rename jevoisbase-1.10.0 folder into jevoisbase.

Answer 1

so, for this one, you are using opencv4, which has eliminated support for the old opencv1 interface, and the eye tracker code was written for opencv1. So we have disabled that eye tracker module a while back. It looks like your problems are coming from maybe being out of date on some components of the software. Did you do a git pull in jevois, jevoisbase, etc to make sure you have the latest?

Incidentally, we are about to publish 1.11 which should resolve these issues.
