[Kdenlive-devel] SVN version build problems

[Aleksander Adamowski]

Hi!

When trying to build kdenlive from sources (SVN revision 1525), I've
noticed that the includes in  trackviewvideobackgrounddecorator.cpp
and krender.cpp are incorrect for my system.

I've followed the building instructions from
http://en.wikibooks.org/wiki/Kdenlive/Getting_and_installing#Installing_from_SVN
(with the addition of mlt++ installation as it's omitted there).
The prefix for all the libs is /usr.
I'm using unsermake.

After mlt and mlt++ installation MLT headers landed in
/usr/include/mlt/framework.

When building kdenlive, preprocessor bombs out because it cannot
locate Mlt.h (notice the capital M):

error: mlt++/Mlt.h: No such file or directory

I've changed the includes to match my system:

Now the build proceeds further, but it bombs out with another,
source-level error:

Any ideas?
