How to cross-compile ros-pkg for arm

edit

Hello. Due to using the armel, I install the ros from the source. Now the roscore can run on the arm succesfully. The ROS packages are compiled directly on board. I want to cross-compile it. But the eros seems to have been abandoned. So I do as the following: Create the cmakelists.txt

cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rostoolchain.cmake)  
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_C_COMPILER /opt/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-linux-gcc)
set(CMAKE_CXX_COMPILER /opt/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-linux-g++)
set(CMAKE_FIND_ROOT_PATH /opt/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM BOTH)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)    
ADD_EXECUTABLE(mrobot_driver src/mrobot_driver.cpp src/mrobot_comms.c)
SET(BOOST_ROOT /usr/include/boost)

than :

 $ camke .
 $  make

I got the error messages:

Building CXX object CMakeFiles/mrobot_driver.dir/src/mrobot_driver.o

While , boost/math/special_functions/round.hpp does exists. And the path of boost is right. Is the method of cross_compiling correct? Please help me.thank you very much.
