Read function in magick++ wont compile - c++

Question

#include <iostream>
#include <Magick++.h>
int main()
{
Magick::InitializeMagick(NULL);
Magick::Image im;
im.read("/home/chase/Desktop/m42.jpg");
im.display();
return 0;
}
I get the following error when I try to compile in eclipse...

Why does the read function not compile. I used the package config tool in eclipse to set up Magick++. Also as far as I can tell all the other functions work fine. I am using Ubuntu. I installed Magic++ using sudo apt-get install libmagick++-dev.
Update:
I got it to work. I had upgraded to g++-5. When I compiled with g++-4.9 it worked. Wonder why it does not work with g++-5?

Why does the read function not compile
Your read function does compile. What you have is a link problem.
why it does not work with g++-5
Because g++-4.x and g++-5.x use different ABI, and are not link-compatible (and your libMagick* libraries were built with g++-4.x).
