im working on mpu6050 package, i have a library which is work well outside ROS, but i have a problem to make the package, i wrote a node and i added the headers an and the cpp files to include directory in my package , when i do catkin_make, the node can't see the headers , thats what i got:

/home/ahmed/catkin_ws/src/mpu6050/src/mpu6050_node.cpp:12:21: fatal error: mpu6050.h: No such file or directory
compilation terminated.
mpu6050/CMakeFiles/mpu6050_node.dir/build.make:62: recipe for target 'mpu6050/CMakeFiles/mpu6050_node.dir/src/mpu6050_node.cpp.o' failed
make[2]: *** [mpu6050/CMakeFiles/mpu6050_node.dir/src/mpu6050_node.cpp.o] Error 1
CMakeFiles/Makefile2:379: recipe for target 'mpu6050/CMakeFiles/mpu6050_node.dir/all' failed
make[1]: *** [mpu6050/CMakeFiles/mpu6050_node.dir/all] Error 2
Makefile:138: recipe for target 'all' failed
make: *** [all] Error 2

i did changes to my CMakeList.txt as questions before me but nothing happened

any ideas ?? thank u in advance.


cmake_minimum_required(VERSION 2.8.3)

find_package(catkin REQUIRED COMPONENTS rosconsole roscpp rospy sensor_msgs std_msgs)

catkin_package( INCLUDE_DIRS include LIBRARIES mpu6050 CATKIN_DEPENDS rosconsole roscpp rospy sensor_msgs std_msgs )

include_directories(include ${catkin_INCLUDE_DIRS} src/mpu6050/include/mpu6050 )

maybe post your CMakeLists then?

Don't post edits as answers. There is an edit button below you question. Use the formatted text button for code (the one with 1s and 0s).

Can you link to github or whatever hoster? This would make live easier.

Otherwise: Post the line where you include the file, as well as the layout of your package (which file is where). Where is the mpu6050.h located?

Please edit your question

i'll link it. mpu6050.h is in include directory

Well, your workspace setup is crooked (at least to the CMakeLists.txt and we do have nothing else).

I see the following paths:

  • src/mpu6050/include/mpu6050 -> this seems like include files, but they are in src?
  • include/mpu6050 -> but there are .cpp files?
  • src/mpu6050/src/mpu6050_node.cpp -> this is the file with the error
  • include -> this is where you say the mpu6050.h is?

And this is all in the following directory: /home/ahmed/catkin_ws/src/mpu6050/src/mpu6050_node.cpp?

So my next question is: Where is your CMakeLists.txt? It seems to me you have the CMakeLists.txt directly in catkin_ws which is just wrong.

Best put the full workspace on github, not only the CMakeLists.txt so that we can try to reproduce.

in this link, the last version of CMakeList, after catkin_make, ros can read the mpu6050.h but it said that it has no members "the methods" like that iam using in the node file

i guess the linking is good, but something wrong with my libraries
