./interface/c++/sample/main.cpp compilation failed

What steps will reproduce the problem?

when try to geenrate the sample executable, it's fails.

What is the expected output? What do you see instead?

collect2: ld returned 1 exit status
make: *** [main] Error 1

2. change the makefile to add "-lpthread -lrt" :

run: main
    ./main

main: ../libxbee.o main.cpp
    g++ $^ -o $@ -lxbee -lpthread -lrt

3.- execute again "make", it shows:

g++ ../libxbee.o main.cpp -o main -lxbee -lpthread -lrt
./main
libxbee(): -6 - An I/O request failed

4 .- when I execute the binary generated always said:

libxbee(): -6 - An I/O request failed

I consider this a bug in the new Ubuntu toolchain... but I've fixed it anyway :)
see 10d4908c

As for the error in step #4, are you sure you have the correct serial port 
specified in main.cpp:16 - "/dev/ttyUSB0"

• Changed state: Fixed

Yes I test it with the correct /dev/ttyUSB0 port, I can open the xbee pro (868) 
[XBP-08] with a term. Any idea about it? I checked all samples, but Ican't run 
someone without error connection ¿?
