Hi,

I am having some trouble with the rosbuild_untar_file command. I am
using it to unpack a compressed .tgz file, created with "tar -zcf".

Does rosbuild_untar_file work on compressed files?

This is my cmake script:

--------------------------------------------
cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)
rosbuild_init()

set(URL  http://robotics.ccny.cuny.edu/data/ROS/ccny_exp_20100913_bags.tgz)
set(FILENAME ccny_exp_20100913_bags.tgz)
set(UNPACKED_NAME bags)
set(MD5SUM  77f36f36e36d512967f3e4aaad5e09c5)

rosbuild_download_data(${URL} ${FILENAME} ${MD5SUM})
rosbuild_untar_file(${FILENAME} ${UNPACKED_NAME} ALL)
------------------------------------------------


This is the output of make:

------------------------------------------------
...
[ 33%] Generating ../bags
tar: Old option `f' requires an argument.
Try `tar --help' or `tar --usage' for more information.
make[3]: *** [../bags] Error 2
...
------------------------------------------------

Any suggestions would be appreciated.

Thanks,
Ivan
