Lots of errors compiling with ros_lib library since updating libraries

Using Arduino Programming Questions
#1

Hi,

I'm using an Arduino Uno and IDE 1.8.10 (also tried 1.8.4).

Since I updated my libraries a few days ago, my sketches can't be compiled anymore.

one error is:

Arduino: 1.8.4 (Linux), Board: "Arduino Uno"

Error compiling for board Arduino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Other sketches also show errors, but they are too long to post here...
Anybody know whats going on?

#2

Sounds like a problem with that library? Where did it come from? Have you checked the documentation for the latest release of that library?

#3

@DrAzzy
Yeah, guess there's aproblem with that specific library, because the other sketches also give errors about /home/ubuntu/Arduino/libraries/ros_lib/ArduinoHardware.h .
It's the library needed so teh Arduino can interact with ROS via rosserial. The latest documentation is: rosserial_arduino/Tutorials/Arduino IDE Setup - ROS Wiki
Maybe i should try reinstalling that libraray?

I just reinstalled ros_lib, now I’m getting the following error:
