License question

[Daniel Lidström <daniel lidstrom sbg se>]

Hello!

I'm interested in using the ustring from gtkmm, but since our project is
``closed'', I need to know how I can use gtkmm. The license is LGPL, which
as I understand, only allows linking with non-modified gtkmm. Otherwise we
would have to disclose our source code too. But if I use ustring for
example,
I would have to make sure that it is not a template class, since in that
case
no code would likely be linked. So in order to use any part of gtkmm, I have
to know if that piece of code causes linking with the shared library? This
would rule out using any template code that doesn't cause linking with the
shared library, in closed source software.

Hälsningar,
Daniel
