Is there a reason for not creating a static binary of Kdenlive regularly? It would avoid the hassle for new users of trying to find a recent package for their distro (if it exists) or trying to build from source.
Firstly: probably because distributions only accept shared builds to make repositories smaller. In the end, we are convinced that Kdenlive and Melt will make it to the desktops. It is only a question of months. Things are evolving rapidly.
Secondly: the problem of static builds is that you have to decide when "static" ends. Usualy, it is not possible to make pure static builds because the libraries that you would like to build staticly are themselves shared. So you end-up with a monster in size.
The logic behind free software is to make shared builds to reuse the work of others.
Besides, do you experience problems building or using Kdenlive?
