Hello,
After upgrading from Fuerte to Groovy (debian packages under Ubuntu 12.04) I have found rosmake runs much slower than it used to. For example, for one of my typical stacks including 7 packages and mostly Python code, rosmake takes 7.9 seconds under Fuerte and 149 seconds (2 min 29 sec) under Groovy. That's 18x slower(!). Is this expected?
Thanks,
patrick
I guess groovy's rosmake is so slow because rospack is so slow now. This is also the topic of this Q/A. Would of course be very interesting if any improvements are planned as this affects a lot of people.
Thanks @Stefan Kohlbrecher. I didn't see a ticket on this problem so I logged one here: https://github.com/ros/rosdep/issues/218
I confirm the patch mentioned above also worked for us, reduced the compilation time of almost empty packages by a factor of almost 5. For the lazy, here is the list of instructions to install it.
sudo apt-get install python-jsonpickle --yes
cd /usr/share/pyshared/rosdep2/
sudo rm sources_list.py
sudo wget https://raw.github.com/ros/rosdep/b0aaeb0fd1e12c6e857d7ebe1785c61f90df5a5a/src/rosdep2/sources_list.py
rosdep update
rosmake <package>
On my system the source_list.py file that rosdep uses is located in /usr/local/lib/python2.7/dist-packages/rosdep2 , instead of the directory specified (ubuntu 12.04, installed from debian package) The patch improved things a bit but is I think still quite slow compared to fuerte or catkin
A fix for this would be to move to the new catkin build system - it is faster than the original rosbuild. I believe rosbuild is slow now because it has been "patched" to work along side catkin, but eventually it will be depreciated - if I understand correctly.
