The problem is not Qt in this case but the GPL. Assuming the installed software is considered an integral part of the installer, the installer would have to be released with a GPL-compatible license. I am not sure how this could be achieved with Qt (commercial).
Right, I understand. So the risk is that one of the LyX developers could sue you when you release an installer that contains a commercial Qt.
I have a commercial licence.
That's great news.
However, I am reluctant here because there is a clearly better option with using Qt4.
I totally agree that Qt4 is a better option and completely solves this issue. However, it will probably take a year or so before LyX 1.5 with Qt4 is released.
I'm currently working on a new installer for LyX/Win 1.4 that fixes all the current installation related issues. It would be great if there would also be a solution to provide an installer that works on Win98/Me and doesn't have all those annoying Q../Free bugs.
Woudn't it be an idea to mail all the developers (http://www.lyx.org/about/blanket-permission.php) and ask them whether they want to a make a special exception for linking with a commercial Qt?
Previously there has been such as exception for the non-GPL xforms library. Joost
