Thank you. Your answer explains.

Hi there. I have installed ROS on Mac OS and found there are source files in most packages' src folder. But in Ubuntu, ROS packages reside in opt folder and I can not find source file. What is the difference?

Hi Prima89, I'm interested in muti-robot planning and have tons of questions in how to implementation in ROS. Could you please walk me through the idea? Thank you.

This works for me too. Thanks a lot and I think I learnt a lot from you!

I'm trying to install robot_pose_ekf to Mac OS. I can just clone it from gitbut and catkin_make it. Please see my question at orocos-bfl. Thank you.

@gvdhoom

Yes , I asked as a question at orocos-bfl. Sorry about that. I tried to add everything to the CMakeLists.txt of the package I want to install(robot_pose_ekf), but it does not work. Thank you.

Hello all, I was trying to catkin_make "robot_pose_ekf" package I cloned from github and it's CMakeLists.txt is: link text. The output error was:

checking for module 'orocos-bfl'

--   package 'orocos-bfl' not found

CMake Error at /usr/local/Cellar/cmake/3.1.3/share/cmake/Modules/FindPkgConfig.cmake:340 (message):
  A required package was not found
Call Stack (most recent call first):

  CMakeLists.txt:13 (pkg_check_modules)


-- Configuring incomplete, errors occurred!

<== Failed to process package 'robot_pose_ekf':

Then I cloned "orocos-bfl" package from github and when I catkin_make it, the output was:

Packages not found in the workspace: orocos-bfl

Then I followed bfl-ROS.wiki the following lines to CMakeLists.txt of "robot_pose_ekf" package:

   1 find_package(PkgConfig)
   2 
   3 pkg_check_modules(BFL REQUIRED bfl)
   4 
   5 message("BFL include dirs:" ${BFL_INCLUDE_DIRS})
   6 message("BFL library dirs:" ${BFL_LIBRARY_DIRS})
   7 
   8 include_directories(${BFL_INCLUDE_DIRS})
   9 link_directories(${BFL_LIBRARY_DIRS})
  10 
  11 [..]
  12 
  13 # for every target using BFL:
  14 target_link_libraries(your_executable ${BFL_LIBRARIES})

In the original CMakeLists.txt there is a line:

pkg_check_modules(BFL REQUIRED orocos-bfl)

and I just substituted is orocos-bfl with bfl as suggested and insert rest of above lines. The result was, this did not work, output was:

package 'bfl' not found

which is installed already and can be found by rospack:

/Users/hxin1/ros_catkin_ws/src/bfl-release-release-indigo-bfl-0.7.0-6

Hi jarvisschultz! Please forgive my ignorance. I'm new to ROS. Here is how I understand this:

   1 find_package(PkgConfig)
   2 
   3 pkg_check_modules(BFL REQUIRED bfl)
   4 
   5 message("BFL include dirs:" ${BFL_INCLUDE_DIRS})
   6 message("BFL library dirs:" ${BFL_LIBRARY_DIRS})
   7 
   8 include_directories(${BFL_INCLUDE_DIRS})
   9 link_directories(${BFL_LIBRARY_DIRS})
  10 
  11 [..]
  12 
  13 # for every target using BFL:
  14 target_link_libraries(your_executable ${BFL_LIBRARIES})

I just insert the above code from line.1 to line.9 to the top-level CMakeLists.txt in src folder in which all of ROS packages reside. And the line.14 should be in the CMakeLists.txt of the specific package which uses bfl(which is robot_pose_ekf in my case). Is this right? And my question is I'm not sure in what detailed line in the txt file(s) should I insert them. Thank you.

Hi guys! Have you solved the problem?

Hi there, I'm not sure where to add the lines in the second section of the link you provided .To the CMakeLists.txt who uses orocos-bfl? Or to orocos-bfl's CMakeLists.txt? Or somewhere else? Thank you.

Hi guys, I don't know where to add above lines. To the CMakeLists.txt who uses orocos-bfl? Or to orocos-bfl's CMakeLists.txt? Thank you.

Hello guys!

I want to perform navigation task in ROS on my Mac and I found I don't have navigation package. The problem is I remember that I installed full-install of ROS which is said to include navigation package. I have the following questions: 1.How to check the ROS on my Mac is full installed or not. 2.Install package to my Mac. I tried pip and brew on ros-indigo-navigation, they didn't work 3.I just found using ROS directly on Mac OS is harder.

Thanks a lot!

Hi there. Have you got any idea about how to create a map? I have the same question.

@dornhege Thanks it's working now.

It doesn't work. When I entered the two command lines "rm: cannot remove ‘/root/.ros/’: No such file or directory" showed up. What is the problem?

The same thing happens to me. I followed the steps strictly, but it still can not be found.
