Glad to have helped! :) That LaserScan timeout error is actually quite misleading.

2017-04-16 17:05:38 -0500 answered a question rqt segmentation fault following tutorials

Had this same issue, and the fix proposed by @CIRobotics in comments worked for me too. I'll just elaborate on the exact steps I took to resolve it.

The issue is caused by newer versions of packages (python-pyqt5 and python-sip) installed by the Cura PPA. The following steps solved the issue for me:

  1. Uninstall the newer package versions that were installed from the PPA:

    sudo apt remove python-pyqt5 pyton3-pyqt5 python-sip python3-sip sip-dev

  2. Remove the PPA:

    sudo rm /etc/apt/sources.list.d/thopiekar-ubuntu-cura-xenial.list sudo apt update

  3. Reinstall ros-kinetic-desktop-full

    sudo apt install ros-kinetic-desktop-full

  4. Check with sudo apt autoremove for any other packages that were broken by the downgrade and install or autoremove them as necessary.

A more elegant solution might be to use the ppa-purge tool as described here, however, I discovered that link after I had already fixed the issue, so I could not try it out.

Of course, the drawback of the above solution is that you will not be able to use the Cura software on your Xenial system. I'm dual-booting Windows, so I'll just install the Windows version. I'm currently not aware of a more elegant solution.

2015-09-22 09:19:12 -0500 answered a question Build error in orocos_kdl when building Indigo from source on Debian 8.0 (Jessie)

Turns out, the problem was a previous installation of Eigen (probably from source), which wasn't cleaned up correctly. There was an invalid /usr/share/cmake/Eigen-3.0.1/eigen-config.cmake file which was setting Eigen_INCLUDE_DIRS instead of Eigen_INCLUDE_DIR (which orocos_kdl was expecting). The result was that the include flag for Eigen was set to -I instead of -I/usr/include/eigen3. Unfortunately the first error message led me way off the right trail.

Ubuntu 12.04 is using gcc 4.6, Ubuntu 14.04 is using gcc 4.8 and Debian Jessie is using 4.9. I can build orocos_kdl on both Ubuntu versions without problems, but the build fails on Debian. I have also installed gcc 4.8 on Debian and tried building with that, but I get the same error.

I would say no, unless they are turned on automatically by CMake/catkin, because I haven't turned them on manually, but I'll check tomorrow when I get back to work. Thanks for helping me out with this!

The disk is only 30% used, the directory is created. Also, CMake version doesn't seem to be the issue. I have tried CMake 2.8.9 and 3.0.2, both work on Ubuntu Precise, none work on Debian Jessie. The one difference I notice is that the file build order is different on the two systems. I'm stumped

2015-05-31 19:11:04 -0500 asked a question Build error in orocos_kdl when building Indigo from source on Debian 8.0 (Jessie)

I am trying to build ROS Indigo from source on Debian Jessie, following these instructions. So far, I have successfully built the ros_comm variant and can run roscore. I'm now trying to build the robot variant. 20 of 116 packages get built successfully, but the build fails when it gets to 'orocos_kdl'. Here is the full error output:

Reproduce this error by running:

Command failed, exiting.

I can't really understand what went wrong, seems like segment.cpp.o and chainiksolvervel_pinv_givens.cpp.o do not get built correctly, but I don't understand why. Copying the whole orocos_kdl folder to my other machine running Ubuntu Precise and building it there works flawlessly. I'm suspecting it might have something to do with the CMake version (Debian has CMake 3.0, while Ubuntu has 2.8.9).

Any help will be greately appreciated!

This does not seem to work for me. I'm running Hydro on 12.04, e.g., both

and

apt-get source ros-hydro-slam-gmapping

Am I missing something?

2014-10-20 20:13:18 -0500 marked best answer Is there a tf:MessageFilter in the tf Python API?

The tf::MessageFilter Tutorial shows the C++ API. Does this functionality exist in the Python API?

Doing a quick search:

grep -i -R --include=*.py messagefilter .

from the tf folder doesn't yield any results.

A colleague of mine made a NAV driver+ROS wrapper recently, based on the sicktoolbox code. It's available here:

The code needs some tyding up and there are a several hardcoded things, but we're currently using it on a project and it works :)
