Re: [ros-users] vslam install

I'm using cturtle and followed the instructions at
http://www.ros.org/wiki/vslam, but encountered an error about DMatch:

vslam/frame_common/include/frame_common/frame.h:207: error: ‘DMatch’
is not a member of ‘cv’


I don't see DMatch in my vision_opencv or in any of the files the checkout
of the unstable tag pulled in. I tried copying DMatch from
https://code.ros.org/trac/opencv/browser/branches/features2d/opencv/modules/features2d/include/opencv2/features2d/features2d.hpp?rev=3589and
got the build to this error:

vslam/frame_common/src/frame.cpp:163: error: no match for ‘operator=’ in
‘((frame_common::FrameProc*)this)->frame_common::FrameProc::detector =
(int*)operator new(4u)’

I think I could hack further but I'm curious if there's a correct way to get
vslam built.

Thank you,

Lucas Walter
