Hi,

I am trying to compile all the packages in Arch Linux but I received an error. I installed with success the ros-core. Now the problem is this: I followed this guide but when I write the command:

rosmake -a

I receive this message:

mkdir -p bin   cd build && cmake -Wdev
-DCMAKE_TOOLCHAIN_FILE=`rospack find rosbuild`/rostoolchain.cmake  ..   [rosbuild] Building package ivcon   [rosbuild] Error from syntax check of ivcon/manifest.xml   Traceback (most recent call last):

It seems that I have not rospkg installad, but it is not. I follewed this post without success. Could you help me? Thanks in advance
