Code signing Qt frameworks: is it legal?
I'm developing an app for OS X and I would like to know if it's legal to sign the Qt frameworks included in the bundle with my personal certificate.
Depends on the license you are using Qt under, of course. Under commercial license, you can do almost anything with Qt, so signing should be ok. Under LGPL, I also think you are allowed to do it (especially if you need to do it in order to publish the application), as long as you allow the libraries to be swapped (LGPL requirement!), and you inform your users that you are using Qt.
