ccRTP (and commoncpp) GPL linking exception ..

Rate this Message:
Hi.
I've evaluated ccRTP for an application we are developing (I did have to apply a few minor patches for VS 2008 but now it compiles and works) and so far it seems to work quite well. I've been wondering about the linking exception .. I read both the COPYING.addendum file and http://www.gnu.org/software/ccrtp/doc/manual/html/GNU-ccRTP-Linking-Exception.html . If I understand it right it means that I could link the library in a closed source commercial program. Please correct me if I'm wrong .. I'm not really good with license stuff...

All use cases and licensing is exactly the same as found with GCC
libstdc++. You are essentially correct, or to look at it another way, you are license compliant with ccrtp as per the linking exception if you are already license compliant with libstdc++ and are not otherwise modifying the distribution of ccrtp itself as you had received it.

I should add, however, that the ZRTP extensions (which is separately
distributed) are licensed using the GNU General Public License without a linking exception. If you are using the zrtp extensions, then you will need to license your software under a GNU GPL compatible license.

Thanks for the fast answer.
So basically if I make any changes/fixes (e.g. neither commoncpp nor ccrtp would compile as-is with visual studio 2008 so I had to change project files and apply 1 or 2 small fixes) I'll have to make those available as normal, but just using the library (I assume it doesn't matter if static or dynamic) is fine without having the GPL apply to the rest of my code. Correct?

The changed library would either still be either under the GPL only, or
under the GPL with the linking exception, at your choice. In either case, you would have to distribute/make source available to your changes to the library(ies) to propogate the changed libraries. This is relevant to the libraries only, however, and not the linked application, unless you chose to redistribute the libraries as GPL only. If the changes to the libraries are small, I would be happy to review and include them in the next release.
