2014-01-28 17:25:25 -0500 marked best answer How are ROS debian packages compiled?

Hi, I'd like to know if there's any documentation on the gcc flags used to compile the Debian ROS packages. I assume -O3 is used everywhere and that sse1-3 is only enabled on those packages which contain rosbuild_check_for_sse(), but I'd prefer to have this documented, to verify whether I need to rebuild it myself to have maximum performance on my machines.

thank you

2014-01-28 17:24:36 -0500 marked best answer How to Log connections

Hi, How can I log ROS TCP connection creations and destructions? I'm trying to move all my clients to persistent connections to avoid recreating too many TCP sockets (to avoid they dangle for a couple of minutes), but I still have many TIME_WAIT connections (for which I cannot see to which process they belong with netstat nor lsof -i)

Maybe enabling logs for roscore? We have diamondback but we're migrating soon to electric.

thanks

when rosinstalling on my machine with svn 1.7.1, I get the following error:

svn: E170000: Unrecognised URL scheme for 'https://code.ros.org/svn/ros/stacks/ros/tags/ros-1.4.10'

The workaround is using svn 1.6. Is there any better workaround?

It sounds fine, thanks. Maybe we can also do it with "cmake -C cacheLocal.cmake"

2013-09-24 11:11:01 -0500 asked a question $ROS_ROOT/rosconfig.cmake fot catkin?

What is the equivalent of $ROS_ROOT/rosconfig.cmake fot catkin? I want to set some build flags for all my catkin packages.

thanks

2013-05-15 05:41:20 -0500 commented answer cannot install at all (ubuntu 12.04 amd64)

Why are groovy and hydro debians for Ubuntu 12.4 not compiled against boost 1.48? Ubuntu 12.4 comes both with boost 1.46 & 1.48, but 1.46 has some problems with c++11

2013-02-04 07:22:14 -0500 asked a question How can I run stacks tests with valgrind?

I could run this, but then I'm also instrumenting all the cmake calls

valgrind --trace-children=yes --trace-children-skip="/opt/*" make test

You can workaround installing ubuntu 12.10's libraw1394, libraw1394-dev and libraw1394-tools packages

2013-01-16 01:44:28 -0500 asked a question API to know if a node is alive?

I could run a system("rosnode ping -c1 /nodeName"), but this always return return code 0. I could grep the standard output of rosnode, but it sounds quite dirty.

thanks

thanks! When I run apt-cache search ros-groovy I get many groovy packages, but not the variant one. Maybe because I'm in 32bits and beta is only available for 64?

Hi, I'm trying to build groovy on ubuntu 12.4, following www.ros.org/wiki/groovy/Installation/Source .

The following works fine roslocate info ackermann_msgs

but if I try to get info for desktop or desktop-full variants, as described at ros.org/reps/rep-0131.html#variants , I get

~/ros$ roslocate info desktop
cannot locate information about desktop

Where is the list of variants that I can select?

thanks
