Correct, \n gives me a newline but since the flush is not there I miss out on almost all of my notifications. So I had to replace all \n with std::endl. Several osg examples has the same flaw so they should probably be changed to std::endl.
I wanted to raise this because more people could be in the same situation without knowing it. It is quite subtle but potentially dangerous IMHO. /Per On 14 July 2014 01:32, Robert Osfield <[email protected]> wrote: > Hi Per, > > I think you'll find that \n is working - it creates a newline, but just > isn't doing a flush like you want it to.
