Hello, I have just started to work with Bumblebee2 package which i checked out from http://cu-ros-pkg.googlecode.com/svn/trunk/bumblebee2 , under ROS Diamondback and Ubuntu 11.04. I do rosmake, and i get a problem with one of its dependencies which is the package libdc1394v2 and it is already under /opt/ros/diamondback/stacks/libdc1394v2. I am pasting part of the output from rosmake below : [rosmake-3] Finished <<< camera_info_manager ROS_NOBUILD in package camera_info_manager [rosmake-1] Finished <<< dynamic_reconfigure ROS_NOBUILD in package dynamic_reconfigure [ rosmake ] All 14 linesibdc1394v2: 0.5 sec ] [ 1 Active 42/44 Complete ] {------------------------------------------------------------------------------- mkdir -p build if [ ! -f libdc1394v2-svn-r580.tar.gz.md5sum ]; then echo "Error: Couldn't find md5sum file libdc1394v2-svn-r580.tar.gz.md5sum" && false; fi `rospack find rosbuild`/bin/download_checkmd5.py http://pr.willowgarage.com/downloads/libdc1394v2-svn-r580.tar.gzbuild/libdc1394v2-svn-r580.tar.gz `awk {'print $1'} libdc1394v2-svn-r580.tar.gz.md5sum` [rosbuild] Downloading http://pr.willowgarage.com/downloads/libdc1394v2-svn-r580.tar.gz to build/libdc1394v2-svn-r580.tar.gz...Traceback (most recent call last): File "/opt/ros/diamondback/ros/core/rosbuild/bin/download_checkmd5.py", line 56, in sys.exit(main()) File "/opt/ros/diamondback/ros/core/rosbuild/bin/download_checkmd5.py", line 28, in main urllib.urlretrieve(uri, dest) File "/usr/lib/python2.7/urllib.py", line 91, in urlretrieve return _urlopener.retrieve(url, filename, reporthook, data) File "/usr/lib/python2.7/urllib.py", line 241, in retrieve tfp = open(filename, 'wb') IOError: [Errno 13] Permission denied: 'build/libdc1394v2-svn-r580.tar.gz' -------------------------------------------------------------------------------} [ rosmake ] Output from build of package libdc1394v2 written to: [ rosmake ] /home/edibra/.ros/rosmake/rosmake_output-20110620-115234/libdc1394v2/build_output.log [rosmake-0] Finished <<< libdc1394v2 [FAIL] [ 0.45 seconds ] i was thinking maybe there are some building problems inside the libdc1394v2 package itself. but i cant seem to figure it out why :S. There is no CMakeLists.txt file inside it, maybe thats the problem ? then does it mean that i have downloaded the wrong package ? if so where can i download the correct one ? if any one has any idea please let me know thank you in advance endri
