It worked! ```bash echo ">=dev-games/ogre-1.10.12 experimental" >> $EPREFIX/etc/portage/package.use emerge dev-games/ogre # Maybe 'emerge dev-games/ogre[experimental]'? ``` Did the trick to emerge `ros-kinetic/opencv3`. Uhm, @allenh1 how do we approach this for anyone...

I have not managed to have ROS deal in a friendly manner with Python > 2.7, but I do have python 2.7 and 3.6 living together. This is what I...

I'd say check your PYTHON_PACKAGE_PATH env car to be sure it's not pointing to something py3. Also check the catkin related packages for py3 shebangs. If nothing interesting comes up,...

You installed catkin with Python 3.6 Target still enabled and that wrote that setup file and it messed up your PYTHONPATH For any script. I did the same once. I'd...

Oh man, that is hard. I'd grep the hell out of the filesystem for Python3 references. Try the lib/python2.7 folders, both Gentoo and ROS overlay. Any combination you can think...

Also, not directly related to that, but vtk-8.2.0 right now doesn't build correctly as it needs media-libs/glew and dev-libs/plugixml and they aren't declared in their dependencies, they must be emerged...

I don't know what is that demo, but related to Nvidia docker running stuff with X I can copy paste what I wrote some time ago (and use for some...

This looks interesting: https://github.com/ros-visualization/rviz/pull/1242 Even tho I don't think the problem really comes from there... `Ogre::DataStreamPtr` should have a `bind` method: https://ogrecave.github.io/ogre/api/1.10/class_ogre_1_1_shared_ptr.html

Oh, just found out about bind: > this api will be dropped. use reset(T*) instead I'd expect a deprecation warning not an error on compiling... After doing that substitution in...

I kept drilling it and made a patch that successfully compiles Rviz: https://gist.github.com/awesomebytes/c1ba75ec3329aa63d768320b43743e70 (I applied it by hand and it worked, now I'm trying emerging ros-kinetic/rviz with it in $EPREFIX/etc/portage/patches/ros-kinetic/rviz)....
