How to cross-build for a different Linux version (w/ Qt Creator)?

Yes, of course. I did an "apt-get install qtcreator" which installed this all:

Is anything missing?

[wysota]

So is the problem with your project or with lack of valid Qt installation? Can you build the project from the command line?

[Hes]

I have never built a Qt project from the command line before, so I really can't say whether that works (or how to do it). I you tell me what to test, I will happily try.

So far, I tried to load the project which worked both in the new qtcreator and in the one from the old installation. It fails to load in this new schroot enviroment, though, with the error listed above.

Open a chrooted commandline, cd to the project directory, call qmake and make.
