For the usual reasons I can't give any legal advice. But a common interpretation of the LGPL is that you can 'depend' on LGPL libraries (e.g. Qt Creator plugins/libraries) in your code with a different license, provided that the user can easily change the LPGL libraries underneath (and that your license doesn't somehow 'infect' the LGPL ones). See e.g. the wikipedia article about LGPL. > I'd be thankful for any recommendation. I'd just go for LGPL 2.1. It's probably the one given the least headaches in Qt Creator, since Qt Creator is available under this license, too.
