script error #1

Closed blankered closed 9 years ago

blankered commented 9 years ago

Thank you for creating this script! But like every installation of ROS I perform on my Edison or Jetsen TK1, I always run into errors. I cloned the repository to my home directory and ran the ros-install script from the downloaded directory. I created the px4 user account as the directions said. Here is the error output I am receiving.

Are there some packages I need to fix manually?

SimonWilks commented 9 years ago

Line 56 should read cd ~/ros_catkin_ws and not cd //ros_catkin_ws. Can you check if the /home/px4/ros_catkin_ws directory exists?

I also noticed the README said to run the script with sudo though it should catch this. I just updated the instructions.

If you don't won't any (or less) problems you might want to just copy paste each line one at a time.

I think the first issue is that I have no "px4" user directory. When I login using the created px4 account information, it redirects me the /home directory. Would this cause issues? I will reflash the board and attempt to follow the instructions again.

Ah! I see the problem. In the instructions I say useradd but unlike the adduser app based on it it will not create a home directory. Will update the instructions again in a sec.

If you don't mind reflashing that would be great. My board is operational at the moment and I can't retest at the moment.

SimonWilks commented 9 years ago

Done. And yes it will have messed everything up.

blankered commented 9 years ago

Im running through the instructions again. One thing I think might be useful to add is:

  1. How to mount microsd card "
  2. How to change the /var/apt/cache directory to the mounted sd card
  3. How to change the symbolic directories to forward to the mounted card while this feature would free up space on the board

I think the instructions are as follows, maybe wrong 1.) fdisk -l look for sd card id 2.) mount -t vfat /dev/(sd mount id) /mnt 3.) copy directory /var/cache/apt to /mnt 4.) ln -s /mnt/apt/archieves /var/cache/apt/archieves

SimonWilks commented 9 years ago

I'm using the breakout board which doesn't have an SD card slot. Happy to add the instructions once you verify them.

SimonWilks commented 9 years ago

@blankered any luck with the installation? If not I just received a second Edison that I can use for testing and I can run through it and clean it up tomorrow.

blankered commented 9 years ago

The script works perfectly! Nice work. Now I am trying to figure out how to free up some space now. I was exploring options about booting from the SD card directly but I have had little success on finding resources about doing this.

SimonWilks commented 9 years ago

Great. Thanks for testing it :)

One thing you can move is the cache directory which may give a fair bit of space back:

mv /var/cache /home
cd /var
ln -sf /home/cache cache

I am having problems running the "roslaunch mavros px4.launch" command from the "ros_catkin_ws" folder. I moved my /opt/ros/indigo to /mnt/indigo with the following similar commands above to make more space. I simply get command not found with I run in normal and sudo mode. I am not sure how to fix this issue. I will try and move the indigo folder back and report back.

EDIT: I didn't properly forward the directories. I fixed that "ln -sf /mnt/indigo /opt/ros/indigo" while in super user mode. The "roslaunch mavros px4.launch" command now works. And I have a bunch of space!
