Hi all,

I am trying to install the point cloud library in ROS Indigo, Ubuntu 14.04. I tried several different ways, but no one works.

First, I created the package in a workspace, followed here, and execute the command showed here

rosdep install --from-paths ~/Documents/Projects/catkin_ws/src/my_pcl_tutorial --ignore-src -r --rosdistro indigo -y

However, it shows this

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
my_pcl_tutorial: No definition of [libpcl-all] for OS version []
Continuing to install resolvable dependencies...
executing command [sudo -H apt-get install -y libpcl-dev]
[sudo] password for alex: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libpcl-dev
ERROR: the following rosdeps failed to install
  apt: command [sudo -H apt-get install -y libpcl-dev] failed
  apt: Failed to detect successful installation of [libpcl-dev]

The problem remains if I execute

sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
sudo apt-get update

I also followed the answer here, the same problem occurred. I was confused that I thought it should install libpcl-all, but not libpcl-dev, because I was in Ubuntu 14.04, Indigo.

Then, I tried to follow the instructions from the pcl official site. Remove /etc/apt/sources.list.d/v-launchpad-jochen-sprickerhof-de-*, and execute

sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
sudo apt-get update
sudo apt-get install libpcl-all

After that, I 'catkinmake' in my workspace where I created a pcl package like this, but it shows 'Could not find a package configuration file provided by "pclconversions'.

Can anyone please help me to solve the problem? many thanks.
