Unit 6 - Fatal error: rrbot_hardware_interface/rrbot_hardware_interface.hpp: No such file or directory

I am doing the ROS Control course and am at the unit: 6 - Hardware Abstraction Layer
I have issues compiling my package using catkin_make:

It states that the directory for the header file, cannot be found in on the first line in the .cpp file, but I cannot see how this is the case.

Hello @asgerdl, let’s first have a look at the CMakeLists.txt file. Could you please post it here?

Thanks,

Roberto

Hallo, Yes I finally found the mistake, which was in CMakeLists.txt.
I had written:
include_directories(
[SPACE]include
${catkin_INCLUDE_DIRS}
)
but it should have been:
include_directories(
[TAB]include
${catkin_INCLUDE_DIRS}
)

Very easy to miss, for the naked eye! :slight_smile:
