PCL missing when building Indigo for raspberry pi

I'm trying to setup the ros stack for indigo on my raspberry pi B+ according to

http://wiki.ros.org/ROSberryPi/Instal...

I deviate from the script and specified the robot and perception package and during the actual building of the workspace I get problems from the pcl_conversions package. FindPCL.cmake seems to be missing causing tears.

This is what I get:

By not providing "FindPCL.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "PCL", but
CMake did not find one.

Could not find a package configuration file provided by "PCL" with any of
the following names:

 PCLConfig.cmake
 pcl-config.cmake

Add the installation prefix of "PCL" to CMAKE_PREFIX_PATH or set "PCL_DIR"
to a directory containing one of the above files.  If "PCL" provides a
separate development package or SDK, be sure it has been installed.

I'm quite new to ros so this is a major stumbling block for me. I found some references that PCL needed to tweek some flags in the build scripts in src/pcl but there is no sorce code there for pcl. Where should pcl be coming from? shouldn't the dependency resolve step figure out I need this one?

At a loss here, any help appreciated.

I just ran into the same issue, after installing the perception variant of ROS on a Raspberry PI 2.

Does anyone have or know of any good instructions on installing PCL on the RPI2 ?

I found this: http://rpi-hacks.blogspot.com/2013/08... however this is probably for the first generation RPI, where cross compilation is way to circumvent the limited RAM issue. So I was wondering if anyone had already attempted to build PCL on the RPI2 - is there enough RAM on the RPI2 to compile PCL natively? Any other caveats?

Much appreciated

I think you didn't install PCL on your raspberry pi and thus pcl_conversion doesn't compile.

You will need to install it but I'm not sure if there is a version of PCL in the repo for Debian and if you compile from source, it might take a while. Here I show how to install a version of ROS on the raspberry that is not the bare bone version (like in your tutorial) and it wasn't so easy. There is some dependencies that I couldn't resolve so I had to remove some packages from the install.

You could try that and remove pcl_conversion, hoping that it won't break anything else. Something like :

wstool rm pcl_conversion
rm -rf pcl_conversion

But you won't be able to use pcl in ROS if you do that.

To be honest, I don't think perception is going to be that useful on a raspberry pi. The link I gave earlier show how to install OpenCV and Openni as well if needed.

looks like the pcl does not list the indigo distribution. Is it not available yet? Would expect a lot of the top level stacks to break if that was the case. Should I be trying out the hydro distribution instead?

Did you have any joy with this as I've come across the same problem?

Thanks
