hi there:

i released a rplidar_python driver last year, but when i check it today, it not belong to me any more, could anyone help me on this problem? thanks advance! appreciate for helping! here is the link http://www.ros.org/browse/details.php...

rplidar_python (indigo)

Author(s):

Maintainer(s): turtlebot2

License: TODO

Source: https://github.com/DinnerHowe/rplidar...

Dependencies:

Description: The rplidar_python package

while, I did a fusion between rplidar and Asus xtion pro, and it works fun now. Due to roswiki is down now, could you please put more information about Orbbec Astra?

while, I figure out how to install qt4

brew tap cartr/qt4
brew tap-pin cartr/qt4
brew install qt

while now the problem is I need to install qt4-no-webkit, when I go through gazebo installation

here is the discussion: https://github.com/mikepurvis/ros-ins...

while it's works for me, maybe you should check empty_world.launch or you should just get a new launch file and retype it.

why you type command like this cd dev/catkin_ws/ bash: cd: dev/catkin_ws/:?

normally, you should type command in terminal like this cd ~/workspace/src, because we usually put our workspace under /home/*** not under /dev/*** , the /dev index is used to store devices.

hi all:

I'm trying to install ROS indigo into Mac Pro with macOS Sierra 10.12.3.

I follow this tutorial(http://wiki.ros.org/indigo/Installation/OSX/Homebrew/Source), however, it does not looks like such easy for me.

now, I have a trouble about qt4, the error is showing below:

CMake Error at /usr/local/Cellar/cmake/3.7.2/share/cmake/Modules/FindQt4.cmake:1318 (message):
  Found unsuitable Qt version "5.8.0" from /usr/local/opt/qt5/bin/qmake, this
  code requires Qt 4.x
Call Stack (most recent call first):

Reproduce this error by running:

I checked my qt4, and tried all solutions in rosanswers forum, None of them worked. while, the qt4 info is showing below.

If this is unacceptable you should uninstall.

Qt Designer no longer picks up changes to the QT_PLUGIN_PATH environment
variable as it was tweaked to search for plug-ins provided by formulae in
  /usr/local/lib/qt4/plugins

thus, could anyone help me on this problem? thank you for reading and thanks advance
