Map_msgs isn't the problem. It also failed to generate the libraries for my custom messages, which I need.

I ran the commands. However, I am now getting: * Warning: failed to generate libraries for the following packages: * map_msgs arduino

All of the help I've seen in my Google and ROS Answers searches to date say to ignore the map_msgs (fine, not using it anyway) but there is nothing on troubleshooting what causes it or how to track down the problem for custom messages.

I'm trying to learn rosserial_arduino. I've worked through the tutorials and am now going back and walking through them with my own code. My initial test code will use rosserial_arduino to turn 8 LEDs on and off. I've created the package (arduino) and a custom message called 8Leds.msg. I added the lines per the tutorials to package.xml and CMakeLists.txt. I source my files and run catkin_make. Everything seems to compile properly and the 8Leds.h file is created in devel/include/arduino. However, when I try to compile the sketch for the arduino I get this error:

In file included from light_8_leds_test.ino:2:0: /home/jcicolani/catkin_ws/devel/include/arduino/8Leds.h:42:18: fatal error: string: No such file or directory compilation terminated.

I don't get it. It's even showing the exact path and file name.

Thoughts?
