Hey guys,

I am installing ROS Fuerte on Ubuntu 12.10 from Source. I was able to do everything but when I do rosmake -a ,I get error:

     rm -f patched
     rm -rf bullet_svn
     rm -rf build
     make[2]: Leaving directory `/home/naman/ros/bullet'
     touch wiped
     mkdir -p build
     if [ ! -f bullet-2.79-rev2440.md5sum ]; then echo "Error: Couldn't find md5sum file bullet-2.79-rev2440.md5sum" && false; fi
    `rospack find rosbuild`/bin/download_checkmd5.py awk {'print $1'} bullet-2.79-rev2440.md5sum`

     CMake Error at CMakeLists.txt:16 (message):

     Build of Bullet failed 

     -- Configuring incomplete, errors occurred!

I have searched a lot on ROS Forums but was not able to find a solution. Any help will be greatly appreciated

Thank you. Naman
