Hi Devon,

I've checked the sources in sources.list.d:

cat pr2debs.list deb http://packages.ros.org/pr2/ubuntu precise main cat pr2debspr2.list deb http://packages.ros.org/pr2/ubuntu precise pr2 cat rosdebs.list deb http://packages.ros.org/ros/ubuntu precise main

No other source is listed in the sources.list file (In fact, all of them are commented #). I think these are special repositories for the PR2 platform. Unfortunately, there is no libfreenect-dev in these repositories.

I'm afraid if I add "http://archive.ubuntu.com/ubuntu/ precise universe" to the robot sources there could be inconsistencies between the packages versions, and our robot will be unstable.

Hello,

I am working on a PR2 robot (hydro) and I would like to install libfreenect-dev to develop a package for rgbd (kinect) mapping. However, I cannot install this library.

I receive the message "E: Package 'libfreenect-dev' has no installation candidate" from the apt-get manager.

I could install it in my workstation (running the same configuration: ubuntu 12.04, ROS hydro) but not in the PR2.

I looked this library into the ros repositories (from the PR2) but I couldn't find it.

Have you experienced this before? Do you have any clue how to install it or why is it not available for the PR2 platform?

I would appreciate your help.

I found the solution to my problem:

As I was using my previous project it had some cache files from the previous buildings that were creating conflicts. I deleted them.

After I manage to pass that issue I found many undefined references due to some third party libraries I am using. I included those third-party libraries. The final CMakeLists.txt file looks like this:

cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)

# Setup
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)
rosbuild_init()

rosbuild_include(qt_build qt-ros)

# Call any of qt-ros' api, e.g.
rosbuild_prepare_qt4(QtCore QtGui QtNetwork)

#set the default path for built executables to the "bin" directory
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
#set the default path for built libraries to the "lib" directory
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)

#third party libraries
FIND_LIBRARY( SENSOR_LIBRARY sensor ${CMAKE_INSTALL_PREFIX}/lib )
FIND_LIBRARY( QDISPLAY_LIBRARY qdisplay ${CMAKE_INSTALL_PREFIX}/lib )

I did not change the manifest file.

Hello,

I am trying to build a ros node with some code I developed to control a robot using some qt libraries. I checked some tutorials but I can not make it build.

I have three files: the main.cpp that creates and call and object of type (which is in client.cpp and client.h). The three files uses qt objects or functions (mainly network and gui elements).

This is how my manifest.xml and CMakeLists.txt look like:

<package>
  <description brief="robot">

     robot

  <depend package="tf"/>
  <depend package="qt_build"/>

  <rosdep name="qt4-qmake"/>

</package>

cmake_minimum_required(VERSION 2.4.6)

#set the default path for built executables to the "bin" directory

file(GLOB_RECURSE QT_SOURCES RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} FOLLOW_SYMLINKS src/*.cpp)


#common commands for building c++ executables and libraries
#rosbuild_add_library(${PROJECT_NAME} src/example.cpp)

target_link_libraries(robot_client ${QT_LIBRARIES})
#target_link_libraries(example ${PROJECT_NAME})

The problem is that if I make a library with my client.cpp (using rosbuild_add_library(cliento src/client.cpp)), "cmake ." or "rosmake" tells me there is a segmentation fault or "terminate called after throwing an instance of 'St9bad_alloc' what(): std::bad_alloc " respectively. And if I do not create the library and include the sources inside the rosbuild_add_executable instruction I will get undefined references from the linking process.

May someone tell me how to properly write my CMakeLists.txt in order to use qt and ros?

I will really appreciate your help.
