Errors at launching laser_scan_matcher demo.launch
Hi there, I'm trying to get the laser_scan_matcher working, I install in through:
$ cd [indigo catkin workspace directory]
$ git clone -b indigo https://github.com/ccny-ros-pkg/scan_...
$ sudo apt-get install libgsl0-dev
$ catkin_make
$ roslaunch laser_scan_matcher demo.launch
(I realise that there isn't an option for kinetic, so according to the wiki, I cloned indigo)
So, when I got the above done, I roslaunch laser_scan_matcher demo.launch, it didn't work as in the site video instead, I got the following errors:
[ WARN] [1540545347.015043625, 1282836371.698945207]: Could not get initial transform from base to laser frame, "base_link" passed to lookupTransform argument target_frame does not exist.

Anyone knows how to solve this?
Please first tell us why you needed to build from source.
The package is released into Indigo and Kinetic and can be installed using
apt-getfor 3 different CPU architectures.I'm trying to clone it because I would like to use navigation stack, but I don't know have odometry. So I'm wondering if laser_scan_matcher can substitute odometry.
I have searched around and saw this, solution provided by mpai227 requiring adding codes into the package..so would like to give it a try..
