High Sierra support

[jmtatsch]

Let's collect some roadblocks and solutions for building on OSX High Sierra:

• Issue: Dependency matplotlib fails to build Solution: https://github.com/Homebrew/homebrew-science/pull/6382

Built successfully 👍 even rviz works, at least until shutting it down...

rqt_image_view has some problems though:

rqt_image_view                                                                                                                           tatsch@JRetinaMacbookPro

Could not import "pyqt" bindings of qt_gui_cpp library - so C++ plugins will not be available:
Traceback (most recent call last):

  Reason: image not found

qt_gui_main() found no plugin matching "rqt_image_view/ImageView"

Is that caused by system integrity protection although i have

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/opt/ros/$ROS_DISTRO/lib

in the beginning of my

/opt/ros/lunar/bin/rosrun ?

@jmtatsch Have you tried just using rqt and then selecting its image_view plugin? I was able to use image_view comfortably in High Sierra, though yes I did disable my SIP.

[jmtatsch]

image_view started as rqt plugin works for me, even with SIP still on. rqt_image_view not working directly is still an issue worthy tracking. Does it work for you with SIP disabled?

[oceanusxiv]

rqt_image_view does indeed work for me with SIP disabled, so it looks like the workaround for SIP is not quite fullproof
