raspberry rosdep initialised, but still asking to initialise

asked 2013-02-07 21:49:46 -0500

Hi

Trying to install ros desktop on raspberry pi.

I am at the resolving dependencies point and the command sudo rosdep install --from-paths src --ignore-src --rosdistro groovy -y fails with ERROR: your rosdep installation has not been initialized yet. Please run: rosdep update

rosupdate runs fine, but the error still happens. Tried running rosdep init again, but get ERROR: default sources list file already exists:Please delete if you want to re-initialize

tried deleting and re-initializing, but still getting the same error

Hi,

I got this to work by running sudo rosdep update. Give it a try.

You should not run rosdep update as root since it creates the database in your user home with root ownership.

Without root access , I was not able to update the database. Is there any reason it cannot be done without root access?

The install instructions have changed on the site - so am now trying to follow those, but am unable to get that to work either. I am trying to use ubuntu in a virtual machine to compile, but once I chroot into the img I can run uname -a and get Linux ubuntu 2.6.32 #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012 armv7l GNU/Linux

but as soon as i try and run any commands from the instructions, apt-get update for example, I get uncaught target signal 4 (Illegal instruction) - core dumped.

Unless you're suing an ARM VM you need to be cross compiling.
