ubuntu 12.04 / ros-hydro / rttlua sefaulting

Hello!

I am getting a segfault when I try running rttlua as it currently exists in
the ros.org ubuntu repositories:

$ gdb rttlua-gnulinux
...
Reading symbols from /opt/ros/hydro/bin/rttlua-gnulinux...(no debugging
symbols found)...done.
(gdb) run

My environment:
$ uname -a
Linux groundstation 3.4.29-rt41 #2 SMP PREEMPT RT Sun Feb 10 21:19:29 CET

$ cat /etc/issue
Ubuntu 12.04.2 LTS \n \l
$ cat /etc/apt/sources.list.d/ros-latest.list
deb http://packages.ros.org/ros/ubuntu precise main

I have the following related packages installed:
sudo apt-get install ros-hydro-desktop
sudo apt-get install ros-hydro-orocos-toolchain
sudo apt-get install ros-hydro-ocl
sudo apt-get install ros-hydro-rtt
sudo apt-get install ros-hydro-rtt-typelib
sudo apt-get install ros-hydro-rospack
sudo apt-get install ros-hydro-rtt-rospack
sudo apt-get install python-rosinstall

I know there is a new ubuntu LTS out, but we're rather fond of our current
12.04 installation since it has the lovely rt kernel we hired
Peter/Ruben/Intermodalics to install for us.

Any ideas?

Cheers,
Andrew

Thanks for the report, this really looks not nice(tm)

Since we're running a bunch on stuff on 12.04, using rttlua, I'm a bit
surprised we're not having it. Could you in addition show a backtrace with
the 'bt' gdb command ?

Sure, here it is!

#7 0x00000000004191b3 in main ()

I also checked that it's not some old rttlua that it is getting called:
$ which rttlua
/opt/ros/hydro/bin/rttlua

My deployer installation is a mess too:
http://paste.ubuntu.com/7652013/

So much is broken in my installation, I will go double-check if there is a
problem with my apt configuration...

Cheers,
Andrew

Hi Peter,

I updated again today, and the rtt package got updated, and things are no
longer segfaulting! Unless you just pushed a change out over the weekend,
I guess our installation was just in some bad state. I ~did do an apt-get
update before posting, but perhaps the connection failed to update and we
didn't notice.

Cheers,
Andrew

Thanks for letting us know so soon, I was just getting started in
looking into it...

Great! I'm glad it didn't cost you much time. The only package that
updated when re-did apt-get install on the rtt related ros packages was:

ros-hydro-rtt

So I suppose that one package somehow got behind the other packages on my
machine.

I just checked with apt-cache show, and it looks like the other packages
you are providing indeed correctly have a dependency on ros-hydro-rtt, so
this must well and truly have been a problem with apt just not updating all
the way on our machine.

Thanks!
Andrew
