Hi, I tried to contribute:

Hi,

is it possible, that the operator=() is missing in the image_geometry::PinholeCameraModel? The following assertion is not true as expected.

void ClassA::setCameraModel( const image_geometry::PinholeCameraModel& cameraModel )
{
   mCameraModel = cameraModel; // fails, since no operator= implemented
   assert( mCameraModel.fx() == cameraModel.fx() );
}

a workaround would be to

void ClassA::setCameraModel( const image_geometry::PinholeCameraModel& cameraModel )
{
   mCameraModel.formCameraInfo( cameraModel.cameraInfo() );
   assert( mCameraModel.fx() == cameraModel.fx() );
}

Or is it not recommended to use the PinholeCameraModel that way?

Hi, thanks for your answers. IsaacSaito, you were right. I gave the plugins the same name. Sorry for disturbing you.

Hi, i was developing rqt plugins. I realized, that only one plugin per directory is loaded. I have the following file structure

rqt_plugins/

rqt_plugins/plugin1/

rqt_plugins/plugin1/plugin.xml

...

rqt_plugins/plugin2

rqt_plugins/plugin2/plugin.xml

if i start rqt_gui, plugin1 is loaded. plugin2 is not.

if I change the structure by means of (mv plugin2 ..) to

rqt_plugins/ rqt_plugins/plugin1/ rqt_plugins/plugin1/plugin.xml ... plugin2 plugin2/plugin.xml

Both plugins get loaded.

I was wondering if only one plugin per directory is loaded, or if I am doing sth. wrong?

Some more information: ros-fuerte 0.1.6-s1355472732~precise ubuntu 12.04

Kind regards, Tobias

Hi, i had to delete

CMakeCache.txt CMakeFiles/ cmake_install.cmake

. Afterwards, rosmake worked fine again.

Hi, I upgraded from diamondback to electric. Compiling my sources with rosmake I get

[rosbuild] Including /opt/ros/electric/stacks/ros_comm/clients/roslisp/cmake/roslisp.cmake [rosbuild] Including /opt/ros/electric/stacks/ros_comm/clients/rospy/cmake/rospy.cmake [rosbuild] Including /opt/ros/electric/stacks/ros_comm/clients/cpp/roscpp/cmake/roscpp.cmake CMake Error at /opt/ros/electric/ros/core/rosbuild/public.cmake:448 (message): Failed to invoke gtest-config

Am I missing a (kubuntu) package? libgtest-dev is already installed on my machine. Unfortunately, it does not contain the gtest-config script.

Any ideas?

Hi mate,

Xlib: extension "GLX" missing on display ":0.0" is more linux related. Try:

sudo apt-get purge nvidia*
sudo apt-get install --reinstall xserver-xorg-video-intel  libgl1-mesa-glx libgl1-mesa-dri    server-xorg-core
sudo dpkg-reconfigure xserver-xorg
sudo update-alternatives --remove gl_conf /usr/lib/nvidia-current/ld.so.conf

(see https://theiszm.wordpress.com/2010/06/27/glx-missing-on-display/). Do not worry about removing ros packages. You can reinstall them afterwards.

Regards, Tobias

Hi, I can answer that myself. I had to add

export GTK_NATIVE_WINDOWS=1

to my environment variables. Though the message still appears, rvis starts as usual.

Cheers, Tobias

Hi there,

after updating ubuntu maverick to natty, I get the following error running rviz

rosrun rviz rviz

(rviz:12054): Gdk-CRITICAL **: IA__gdk_drawable_get_size: assertion `GDK_IS_DRAWABLE (drawable)' failed

(rviz:12054): Gdk-CRITICAL **: IA__gdk_drawable_get_depth: assertion `GDK_IS_DRAWABLE (drawable)' failed

I am using KDE and assume my gtk-settings were wrong. Do I miss a package or something? I would appreciate any help! Thanks!
