[ros-users] rosbuild_untar_file error

[Ivan Dryanovski]

Brian,

I found that using

set(FILENAME ./ccny_exp_20100913_bags.tgz)

instead of

set(FILENAME ccny_exp_20100913_bags.tgz)

works, which confirms what you said. I filed the ticket here:

https://code.ros.org/trac/ros/ticket/3034

Thanks,
Ivan
