Weird compile error using ROS and Gazebo libraries

edit

Hi guys,

Came across the weirdest compile error:

In function `ignition::math::Vector3<double>::operator[](unsigned long) const':
gzwidget.cpp:(.text._ZNK8ignition4math7Vector3IdEixEm[_ZNK8ignition4math7Vector3IdEixEm]+0x2b): undefined reference to `ignition::math::IndexException::IndexException()'

libgazebo_common.so is throwing this.

What the hell is going on ? Im linking ignition_math2 libraries, people in ignition sent me here.

Thanks
