I'm attempting to cross-compile ROS src to a Zynq based ARM system running a version of Angstrom Linux. I've download src (groovy-ros-comm) based on the install from source instructions and created a catkin workspace. I've set up my rostoolchain.cmake file (embedded below) and successfully cross-compiled boost, apr, apr-util and log4cxx.

set(CMAKE_C_COMPILER /home/adminuser/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc)

set(CMAKE_CXX_COMPILER /home/adminuser/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-g++)

set(CMAKE_FIND_ROOT_PATH /home/adminuser/CodeSourcery/Sourcery_G++_Lite)

set(CMAKE_INCLUDE_PATH /home/adminuser/boost-1_50/includes usr/include /home/adminuser/ros_catkin_ws/ros_ext_deps/include)

set(BOOST_ROOT /home/adminuser/boost-1_50)

set(Boost_ADDITIONAL_VERSIONS "1.50" "1.50.0")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_STATIC_RUNTIME OFF)

set(Boost_LIBRARY_DIRS /home/adminuser/boost-1_50/gcc-4.4-arm/)

I'm running into problems with the compilation when it comes to rospack as follows.

Do I also need a ARM python library to link against?

I have read that tinyxml was included with the rospack src, but don't see it and the build process complains it can't find it. Do I need to download its src separately?

If the eventual goal is to compile something like the beginner_tutorials to my target do I need rospack? From rospack depends it appears even the simple ... (more)
