Qt Creator extremely slow when adding large library INCLUDEPATH

[gde23]

Hallo,

i need to use /usr/include/eigen3/ for a project.
As soon as i add "INCLUDEPATH += /usr/include/eigen3/ " to the project Qt Creator gets really slow.
(some seconds for copying word to the editor)
Any ideas haw to fix this. I found some post that suggested adding the path to QMAKE_CXXFLAGS would help, but it didn't.
I guess it has something to do with auto-complete / syntax-highlighting of classes?

Hi,

Which version of Qt Creator are you using ?

@SGaist :
Version of qtcreator is 3.5.1+dfsg-2ubuntu2 running on Kubuntu (16.04)
Version of eigen3 is 3.3~beta1-2

Can you try with a more recent version ? Current is 4.2

@SGaist: That solved it thanks. (sorry for not thinking of that by myself)
