    Default Qt Creator LGPL licensing question

    Hi, i want to develop a freeware Qt Creator plugin application . I will remove all "Digia" plugins from Qt Creator source. Only core, help and project explorer plugins and my own plugin will exist in the final application. I also want to make some small modifications on Qt Creator source like replacing my own logo with Qt logo, modifying some menus and replacing "Qt Creator" name with my company name. These changes will be perhaps on 3 or 4 classes.

    Now my question is that:

    Is there any problem with that as long as i publish the modified part of the source code?
    Is it enough to put a link to lgpl and say "this app uses Qt Creator sources. you can download at here ...on the "about" dialog and put the modified classes into a folder named "modified" in my app?

    What is missing in the above procedure?

    Thanks, regards...

    I am not a license lawer but I think the safest thing is to either ship the modified QtCreator sources with the product or have a them downloadable from your servers for the required period.

    Modified sources in this case meaning everything that is needed to build the LGPL parts of the product.

    Basically a "product-src-someversion.zip" just without the code of your proprietary plugin, i.e. building that should be able to load and work with your plugin.

    Cheers,
