Qt Creator extremely slow when adding large library INCLUDEPATH
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?
Which version of Qt Creator are you using ?
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)
Then please mark the thread as solved using the "Topic Tools" button so that other forum users may know a solution has been found :)
