Hi everyone,
I tried to follow tutorials for rviz in http://wiki.ros.org/rviz/Tutorials/Markers%3A%20Basic%20Shapes
However, after I did it step by step, ros cannot find the package even though I have sourced setup.bash. Can someone help me out? Great thanks!!!

catkin config --install and --no-install using same build dir?
With catkin_make (and earlier versions of catkin tools?) I was able to build to either devel or install, but with catkin config I have to clean and rebuild everything when switching from one to the other- it would be less trouble to use a two profiles:
Error: Attempting to build a catkin workspace using build space: "/home/lucasw/catkin_ws/build" but that build space's most recent configuration differs from the commanded one in ways which will cause problems. Fix the following options or use `catkin clean -b` to remove the build space:
- install: True (stored) is not False (commanded)
$ catkin clean -b
[clean] Warning: This will completely remove the following directories. (Use `--yes` to skip this check)
[clean] Build Space: /home/lucasw/catkin_ws/build
[clean] Are you sure you want to completely remove the directories listed above? [yN]: y
[clean] Removing buildspace: /home/lucasw/catkin_ws/build
Or is there another way to do it that uses the least amount of building and rebuilding? (The second profile approach still requires a duplicate build, but at least doesn't need to be deleted) It seems like if all the cmake args are the same then one build should be able to either be used in place or installed (or dynamic libraries are built differently?)

Catkin not building packages in order
I have just had a really odd problem with catkin_make. I have been successfully building a workspace containing three packages, two with messages and another one with an executable.
So far, removing the build and devel folders and relaunching the command worked fine, but now for some reason the process crashes in the linking phase of the executable while the headers of the other packages are still being generated. This means that I have to relaunch the command several times, getting different errors that come and go as new code is generated each time until finally the executable gets linked successfully.
Any ideas what the problem might be?

Problem tracking down an cmake error in a ROS/gazebo project
I am trying to upgrade a number of ROS/gazebo nodes made by some other developers:
https://github.com/ethz-asl/rotors_simulator
My goal is to get them running with Ubuntu 18.04, ROS melodic and Gazebo 9.
I have been able to solve most of the compile errors, but I seem to have encountered a problem I do not know how to find.
My problem is one remaining error, which I have been unable to determine the cause of.
It is a bit hard to solve a problem if you do not know what causes it in the first place:

I think the problem is somewhere between cmake, gazebo and ROS, but I am not 100% sure.
My main problem is, I do not know how to move forward with this problem, so any input would be helpfull.

OpenCV 3 runtime error "Invalid pointer to file storage" cv_bridge + third party library
I'm trying to publish the image of a [picozense camera](https://www.pico-interactive.com/zense) in a ROS node in **ROS kinetic, Ubuntu 16.04**.
I build a catkin package and included the camera's API (.h and .so files) which is OpenCV3 compatible. This works fine, i can call the API functions in the c++ source code. However, OpenCV crashes at runtime with an error that after some research most posts argue is a conflict between OpenCV2 and OpenCV3. But my installed **OpenCV version is 3.3.1** and i don't have any OpenCV 2.x installed. (Also i'm using cv_bridge which [depends on OpenCV3](https://github.com/ros-perception/vision_opencv/blob/kinetic/cv_bridge/CMakeLists.txt) components)
The only OpenCV package i added to my dependencies and in my code is the *highgui* package. If i leave it out, the node does not crash at all. But even with the highgui package the node runs successfully sometimes.
How can i fix the error?

What does "catkin build --cmake-args -DCMAKE_BUILD_TYPE=Release" actually do?
I recently been exploring using these cmake-args to optimize my code. For the past few weeks I have just been running "catkin build ". Today when I ran "catkin build --cmake-args -DCMAKE_BUILD_TYPE=Release" my code ran 10 times faster.
Should I always be running the second command instead with the build type explicitly mentioned as opposed to simply "catkin build "? Is this a safe practice? I could not find much about this on the internet and I would greatly appreciate some advice.

How to properly install packages from source?
Hi,
I have been reading on how to install packages INTO ROS that aren't included in the ROS installation for a while now and I still don't get it. I am trying to modify source before installing, hence I would like to build it myself.
I am using Kinetic (Ubuntu 16.04 LTS) distro using catkin filesystem. The package I am trying to install is this: [serial](http://wiki.ros.org/serial)
It is available as a .deb package so initially I installed it using `sudo apt-get install ros-kinematic-serial` and that installed fine.
1. First of all, I don't quite get how a package like this one works when installed (or any ROS package). I checked its CMakeLists.txt file, it only installs headers and an example binary file. Going into `cd /opt/ros/kinetic/share/serial` there is only package.xml file and a cmake folder with serialConfig.cmake and serialConfig-version.cmake files. I compiled a basic ROS node using this library and it works fine, so how does ROS know where to find the src files if it only has headers and cmake configs installed?
2. Secondly, if I try to install package from source into ROS, what's the proper way of doing it? I have tried:
cd ~/catkin_ws/src
git clone https://github.com/wjwwood/serial.git
cd ~/catkin_ws/ && catkin_make
source ~/catkin_ws/devel/setup.bash
That works fine, my example node works and I can adjust the source to my liking, but the package is installed to my catkin workspace and not the global ROS path. How do I add the package into the ROS environment so that something like `rospack list`can identify it?
3. Lastly, how come after `catkin_make` I can't find my package using rosrun my_package serial_example_node?
Any help is really appreciated!

How to cross compile for Raspberry Pi 3 ?
Hello,
Compiling my project directly on my raspberry has a high failure rate so I thought the cross compilation was a good option to avoid that. But it appears to be more difficult than I thought and there are not that much tutorials on the internet about this topic.
Can somebody help me figure it out by describing how to proceed step by step not to miss anything ?
**Here's what I did :** ([this answer](https://stackoverflow.com/questions/19162072/how-to-install-the-raspberry-pi-cross-compiler-on-my-linux-host-machine) from stackoverflow helped me a lot)
1) Install the compiler for the raspberry on my computer (running Ubuntu 16.04) -> for my raspberry it's `arm-linux-gnueabihf`
2) Create a `rostoolchain.cmake` file :
SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
#avoid RT_LIBRARY-NOT-FOUND issue
set(CMAKE_LIBRARY_ARCHITECTURE arm-linux-gnueabihf)
#set(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib")
#set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
set(LD_LIBRARY_PATH ${LD_LIBRARY_PATH}
$ENV{HOME}/raspberrypi/devel/lib)
set(PKG_CONFIG_PATH ${PKG_CONFIG_PATH}
$ENV{HOME}/raspberrypi/devel/lib/pkgconfig)
# specify the cross compiler
SET(CMAKE_C_COMPILER /usr/bin/arm-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER /usr/bin/arm-linux-gnueabihf-g++)
SET(CMAKE_FIND_ROOT_PATH $ENV{HOME}/raspberrypi/rootfs)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_LIBRARY_PATH
$ENV{HOME}/raspberrypi/rootfs)
# Set compiler flag
SET(CMAKE_C_FLAGS "${CMAKE_CXX_FLAGS} --sysroot=${CMAKE_FIND_ROOT_PATH}")
SET( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} --sysroot=${CMAKE_FIND_ROOT_PATH}" )
3) Create a catkin profile to cross compile :
Profile: cross

Additional catkin Make Args: None

-------------------------------------------------------------------------------------------------------------------------
Whitelisted Packages: None
Blacklisted Packages: None
4) Finally, run `catkin build` but it generates this warning (I display for only one package) :
Warnings << tile_manager:cmake /home/robotics/raspberrypi/logs/tile_manager/build.cmake.001.log
CMake Warning at /home/robotics/raspberrypi/src/tile_manager/CMakeLists.txt:79 (add_executable):

because there is a cycle in the constraint graph:
dir 0 is [/home/robotics/raspberrypi/rootfs/usr/lib/arm-linux-gnueabihf]
dir 1 must precede it due to link library [libpthread.so]
dir 1 is [/usr/lib/x86_64-linux-gnu]
dir 0 must precede it due to link library [libpthread.so]
Some of these libraries may not be found correctly.
Leading to this error :
Errors << tile_manager:make /home/robotics/raspberrypi/logs/tile_manager/build.make.002.log
/opt/ros/kinetic/lib/libtf.so: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
It seems that there is a conflict with the paths `/usr/lib/x86_64-linux-gnu`, `/home/robotics/raspberrypi/rootfs/usr/lib/arm-linux-gnueabihf` and I have other warnings with `/opt/ros/kinetic/lib` too but I can't find which variable is defining those paths (I think I should only have `/home/robotics/raspberrypi/rootfs/usr/lib/arm-linux-gnueabihf` )
Am I missing something here or is it possible that the issues come from my `CMakeLists.txt` files ?
Any insight would be greatly appreciated.

I looked inside python-catkin-pkg which I installed via apt-get
python-catkin-pkg is already the newest version (0.4.6-100).
It seems to me that somehow I need catkin-pkg version 0.4.3, but installed 0.4.6 via an apt-get upgrade.
Anybody of you has an idea how to solve this error?
Thanks in advance for your advice

How do I do it?

AMCL 'openni-dev' not found
Hi,
I am trying to install AMCL ROS package using catkin_make but i get the following error:
*CMake Error at /usr/share/cmake-2.8/Modules/FindPkgConfig.cmake:283 (message):
A required package was not found
.
.
.
-- Found the following Boost libraries:
-- system
-- filesystem
-- thread
-- date_time
-- iostreams
-- serialization
**-- checking for module 'openni-dev'
-- package 'openni-dev' not found***
Openni is already installed, so, maybe, the problem is that its libraries are not included in the CMakeLists.txt file Boost libraries. In that case, I would like to know how and which openni files are needed to be included.

Problem building with non-installed dependencies
I am making a custom ROS package in C++. The problem I am having is that the build of my node fails, because dpkg-shlibdeps, which gets run during
$ fakeroot debian/rules binary
is failing to find shared objects that are not installed yet. These non-ROS libs have just been built in Jenkins which is then followed by building of non-ROS components which use the libraries and then building of the ROS components.

The CMakeLists.txt specifies to find the libraries at the build location, but this does not seem to be transferred through bloom. These libraries are sucessessfully picked up in other, non-ROS, cmake builds with cpack to package them, with similar find_library stanzas.
EDIT: updated CMakeLists.txt

Note that during run time, the libraries are installed from deb packages, but not at build time. Does anybody know how to get the ROS build mechanism to not fail when it learns of non-packaged dependencies through dpkg_shlibdeps?

importerror catkin_pkg
## Problem
I reinstalled ROS1 Kinetic on Ubuntu 16.04 since I realized I had been using pip, apt, and virtualenvs in the wrong way.
In my system environment, I installed ROS Kinetic following the guidelines which worked fine. However when I run
```
sudo rosdep init
```
I get:
Traceback (most recent call last):
File "/usr/bin/rosdep", line 3, in
from rosdep2.main import rosdep_main
File "/usr/lib/python2.7/dist-packages/rosdep2/__init__.py", line 45, in
from .lookup import RosdepDefinition, RosdepView, RosdepLookup, \

File "/usr/lib/python2.7/dist-packages/rosdep2/rospkg_loader.py", line 37, in
import catkin_pkg.package
ImportError: No module named catkin_pkg.package
I had solved this before by installing it with pip instead of with apt but this apparently isn't the recommended method. I've also encountered other similar import errors before where python doesn't recognize packages installed with apt.

Automatically run tests on ROS build farm for pure cmake project
I'm hosting a [pure cmake project ](http://wiki.ros.org/ifopt)(not dependent on catkin) on the ROS build farm, for which I generate some unit test in my *CMakeLists.txt* similar to:
find_package(GTest)
add_executable(test my_test.cpp)
target_link_libraries(test ${GTEST_BOTH_LIBRARIES} pthread)
add_test(test test)
I can run these with `make test` after a non-catkin build, this works fine.
**How can I tell the ROS build farm (which seems to be internally calling `catkin_make run_tests`) to run that gtest binary as well after building?** [(jenkins-log)](http://build.ros.org/view/Kdev/job/Kdev__ifopt__ubuntu_xenial_amd64/)
I don't want to *catkinize* my project, which would allow me to use `catkin_add_gtest`. I want to keep allowing the ` cd build && cmake ..` pure cmake build for users that don't have catkin installed.
Any help would be greatly appreciated.

Use IKFast in separate package
I am attempting to use some of the definitions and functions found in the IKFast plugin package (more on this below) but am running into trouble adding the necessary dependencies in my CMakeLists.txt
The file structure of the files relevant to me look like this:
myrobot_ikfast_plugin/
include/
ikfast.h
src/
myrobot_group_ikfast_solver.cpp
CMakeLists.txt
package.xml
my_package/
src/
my_iksolver.cpp
CMakeLists.txt
package.xml
Within `my_iksolver.cpp` I require the use of
- IkSolutionList
- IkSolutionBase
- IkReal
- ComputeIk()
The above definitions and functions come from both `ikfast.h` and `myrobot_group_ikfast_solver.cpp`, so I suppose I only really need to include the `cpp` file as it already has a `#include ikfast.h`. Where I'm stuck is editing the CMakeLists.txts to include the few things I need from IKFast.
As noted here by, my lord and savior, gvdhoorn https://answers.ros.org/question/217214/catkin-tools-how-to-include-source-file-from-another-package/, the "elegant" way to do this is to consider using libraries so naturally I tried the following:
Added to `myrobot_ikfast_plugin/CMakeLists.txt`:
add_library(ik_solver src/kuka_arm_ikfast_solver.cpp)
target_link_libraries(ik_solver ${catkin_LIBRARIES})
And added the ik_solver to the install:
install(TARGETS ${IKFAST_LIBRARY_NAME} ik_solver LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION})
Then I added to `my_package/CMakeLists.txt`:
- `kuka_ikfast_plugin` to `find_package()`
- `add_executable(my_iksolver src/my_iksolver.cpp)`
- `target_link_libraries(my_iksolver ik_solver)` (see above created library)
But when attempting to `#include ` I get a build error "No such file or directory`.
So the questions that I would like to be answered are summarized as follows:
1. How should I edit IKFast's CMakeLists.txt so that I can use components of both the cpp and header files.
2. How should I edit my_package CMakeLists.txt and my_package/package.xml to use those components.
3. How should I #include the cpp file (marked as a library) to be used by `my_package/src/my_iksolver.cpp`.
Thanks for the help ahead of time!

Migrating a custom library package used outside of ROS
Hi all,
We have a custom ROS package which exposes ROS services to the outside world (so as to let the app we are developing call ROS services). The ROS package and app used to work fine under indigo (Ubuntu 14.04), now we are migrating to kinetic (Ubuntu 16.04) and it did not work straight away: the compiler cannot find the `#include "ros/ros.h"` and `#include `. It turns out that we had to add the following lines to our app's `CMakeLists.txt` in order to have the app compile:
include_directories( /opt/ros/kinetic/include )
link_directories( /opt/ros/kinetic/lib )
which is ugly and problably not the intended way.
Has anything changed in kinetic regarding the external use of ROS? We did not find much about this in the migration guides (link [here](http://wiki.ros.org/kinetic/Migration) and [here](http://wiki.ros.org/jade/Migration)). What should we actually do, rather than the CMake include and link instructions above? Anyone knows more about the problem?
As a reference, here are the `CMakeLists.txt` and `package.xml` files of the ROS package:
**package.xml:**
