For some reason, there isn't any effect of the type "Enhancement" on my Kdenlive.
Does anybody know what the problem can be?
The three missing are Denoiser, D90 Stairstepping fix and Sharpen from what I can see. What distro, kdenlive version, what Frei0r version and was it from the distro repo's?
is pretty old (2009), many plugins have been added since then.
You will need a later version to get the full set of effects in Kdenlive!
Try this: (changed URL)
git clone git://code.dyne.org/frei0r.git
The main problem is that cmake can't find your C compiler. I am not familiar with cmake, but do you have gcc and glibc installed (developer versions)?
Type gcc at the command line to see...
The other things (no opencv, no gavl, no cairo...) should not be fatal, only certain plugins that use these libs will not be compiled.
Maybe you can compile the old way, something like
sudo make install
If you're on Ubuntu why self compile anyway? There's a perfectly good stable and git PPA available via sunab, near daily automated builds via Dan on the MLT site or the build script to dated folders in your home directory.
