Thank you for responce.
Could you please comment more on this.
As far as I understand from LGPL text, GTK+ can be used by commercial projects too.
As per section (5)

So, the program that uses GTK+ seems to be not required to inherit the license.
The question is, if I'll include a GTK+ dll's into installer, distributive as a whole can be treated as a work derived from the library, since it does contain the library dll's, so the license should be inherited.
But, on other hand, we have a condition in the section (6) declaring the exception:

So, I thought, dynamic linkage can be a desired solution, because user will be able to use another GTK+ version and run an application.
What do you think?

Hello All,
If I'll write a propriate application, that uses GTK+, can I include GTK+
dll's to the program's package (installer)?
cheers
