Hi there,

I'm trying to install the usb_cam package on my Pandaboard (Armel architecture / System Oneric 11.10-Server. I used:

$ sudo apt-get install ros-electric-bosch-drivers

which probably fails because of the armel architecture. Therefore I choosed the installation from source.

$ svn co https://bosch-ros-pkg.svn.sourceforge.net/svnroot/bosch-ros-pkg/branches/electric/stacks/bosch_drivers/
$ roscd usb_cam
$ rosmake --rosdep-install

I get the following failure message:

E: Unable to locate package yaml-cpp0.2.6-dev
E: Couldn't find any package by regex 'yaml-cpp0.2.6-dev'
Failed to install yaml-cpp!
[ rosmake ] rosdep install failed: Rosdep install failed

I installed the yaml_cpp from source with:

$ hg clone ttp://code.google.com/p/yaml-cpp/
$ svn co
$ mkdir build
$ cd build
$ cmake -DBUILD_SHARED_LIBS=ON ..
$ make
$ sudo make install

without any problems. But when I try to make the usb_cam package by:

$ rosmake usb_cam --rosdep-install

it stills produces the same failure (missing yaml_cpp)

By compiling just the usb_cam package:

$ rosmake usb_cam --no-rosdep

it produces the following failure

would be great to get some help because there is a different Question on that with the same kind of problem. http://answers.ros.org/question/36319/how-to-install-yaml-cpp026-dev-how-to-install-from/?comment=36448#comment-36448

It looks like you need to install libavcodec. I don't know the exact command to install it off the top of my head, but the format will look like this:

sudo apt-get install libavcodec

The exact package name might not be libavcodec. It maybe looks something like libavcodec-VERSION-NUMBER or libavcodec-dev. In these situations you can search for packages with a command like this:

apt-cache search libavcodec

This will find all packages that have text containing "libavcodec". This should find the correct package for you to install.

That worked. I just used $sudo apt-get install libavcodec-dev libavcodec53 and compiled it afterwards. thank you very much.
