Unable to compile workspace for unsolved reference to serial::Serial::waitReadable

edit

Hi to all,

I'm kind of new to ROS and I'm having a problem while compiling the catkin workspace on my laptop. I'm using ROS Indigo on Ubuntu 14.04, and I'm trying to compile the irobotcreate2ros package (https://github.com/MirkoFerrati/irobotcreate2ros).

It requires the packages serial and joy to be installed. The problem is that when I compile the workspace, I received the following error:

CMakeFiles/basic_commands.dir/src/irobotcreate2/OpenInterface.cpp.o: In function irobot::OpenInterface::getSensorPackets(int):

This makes me think that probably the compiler is not able to find the serial package. Now:

1. The problem with serial is only related to the waitReadable() function, as if I comment it from the code, the rest of serial references do not rise any compilation error, and the process ends without problem (I've the right configuration of CMake. I know also because I'm using the same CMakeFile I used on other machines, that is the one provided within the package).
2. I compiled this package (irobotcreate2ros) on other machines without problem, so maybe there's a wrong version of serial installed on my laptop. I went digging around on the internet, and I found that previous version of serial (http://rosindex.github.io/p/serial/), e.g. until v1.1.7, didn't have any waitReadable() method. I then checked which version was installed, and it says 1.2.1.
3. To be completely sure, I also went through the code of serial.h in /opt/ros/indigo/include/serial/ to see if there was the waitReadable() method, and it's there (although there ...
