Hi )
library PCA9685 cant find library I2C
Can you post all make output from the beggining?
Looks like something wrong with structure of directories

[tawnkramer]

muddling around this by changing CMakeList.txt to comment out other add_libraries and put all source ( 3 files) in the executable:

add_executable(controller_sub src/controller_sub.cpp src/lib/I2C/src/I2C.cpp src/lib/PCA9685/src/PCA9685.cpp)

[Enhub]

I have a similar error... tried the suggested by @tawnkramer "...put all source ( 3 files) in the executable..." and it did let the "~/pca_ws$ catkin_make_isolated" to finish without an error.

But now trying to run and getting error:

ubuntu@urobot:~$ rosrun ros_pca9685 controller_sub
[rosrun] Couldn't find executable named controller_sub below /home/ubuntu/pca_ws/src/ros_pca9685/ros_pca9685

Could somebody help me please?

Here it is what I have in that folder:
