movegroup eigen error when doing pick [closed]
ubuntu 14.04 trusty

as soon as my pick place node reaches pick the movegroup launch terminal gives this error :

i have gcc 4.8 installed and have been to the mentioned website, but not being too confident about what to do, i would like to know if there is a simple fix for this, and if no simple fix is available then what course of action i should take?
