Hello everyone,

Actually, I am working on Ubuntu 14 and Indigo Version, so am trying to make some packages. I got an error message below :

-- Using these message generators: gencpp;genlisp;genpy
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
Modbus_LIBRARIES
   linked by target "<package_name>" in directory /home/tayssir/catkin_ws/src/robot_ws_debug/src/package_name

-- Configuring incomplete, errors occurred!
See also "/home/tayssir/catkin_ws/build/CMakeFiles/CMakeOutput.log".
See also "/home/tayssir/catkin_ws/build/CMakeFiles/CMakeError.log".
Invoking "cmake" failed

I tried to use ROS_LANG_DISABLE like is mentioned in ROS EnvironmentVariables :

$export ROS_LANG_DISABLE=genlisp

but this can not solve the problem.

How would I fix it? Thanks.

Edit: Thanks for your help @gvdhoorn, and I'm going through the tutorial modbus to install it, and there is my CMAKE File below :

find_path(Modbus_INCLUDE_DIR modbus/modbus.h
   HINTS
   /usr/include/modbus
   /usr/local/include
   )

find_library(Modbus_LIBRARIES NAMES modbus
   HINTS
   /usr/lib/x86_64-linux-gnu
   /usr/local/lib
   )

include_directories(
   ${catkin_INCLUDE_DIRS}
   ${Modbus_INCLUDE_DIR}/modbus
   )

It seems that my environment is set correctly! But I don’t know where is the problem and how can I resolve it??!

thank you very much, your suggestions helped me to solve the problem .. when am looking for the modbus version .. I disc

Thanks i got it ;)

thank you, I try it but it saves only the last value, a = open('goals.txt', 'w+') data_to_save = str(data.pose.x) +

Cannot save data Callback function What I am really looking for is a way to save all value's message that a node receive

What I am really looking for is a way to save all value's message that a node receives (in a list, CSV file..) in a way that I can later do something with this values.

So this is data received :

I tried to put all these values in myData List:

def callback(data):
    id = data.id
    x = data.pose.x
    y = data.pose.y

    #print data
    #list_x.append(x)
    #print id ,x,y
    goals={}
    goals["x"]=x
    goals["y"]=y
    #print goals
    myData=[goals]
    print myData

but it's not what I want(Even with append) ! it put every value in a list like this :

Also, I tried to save this value in a CSV File :

with open('goals_point.csv', 'with') as csvFile:
       writer = csv.writer(csvFile)
       writer.writerows([myData])
       csvFile.close()

it saves only the last value :

So how can I save collected messages (data)? Any idea?

Thanks for answering and for your time in advance,

Tayssir

Thanks, I'm absolute beginner and I'm just getting started learning ROS and I have no idea about rosbag but I will try

I'm absolute beginner in Ubuntu and ROS. I'm using 14.04 LTS (virtualbox) and indigo .I'm just getting started learning ROS and I'm going through the tutorials WritingTeleopNode . I am trying to create to write a teleoperation node and use it to drive the turtle in the turtlesim. First , I create learning_joy/src/turtle_teleop_joy.cpp and the launch File launch/turtle_joy.launch as mentioned in the tutorial . But after adding the following lines to my CMakeLists.txt file:

add_executable(turtle_teleop_joy src/turtle_teleop_joy.cpp)
target_link_libraries(turtle_teleop_joy ${catkin_LIBRARIES})

then building my workspace with catkin_make ,I'm getting the following error :

Linking CXX executable /home/usr/catkin_ws/devel/lib/learning_joy/turtle_teleop_joy

Even that looks red line ? Sorry but because I'am new here so I can not upload image of error.

I know , the code is working but the build is failed because the linking Line appears like an error with red color : L
