[Kdenlive-devel] Compiling kde4 on ubuntu 8.04

[Fran García]

Hi,

I'm a total newcomer to kdenlive, but I really like what I see, and I'd
like to thank all the devs for the terrific job you're doing! I'd really
love to help, I just don't think I have the skills, but that's another
story  ;)

I've benn trying to build the kde4 version on Ubuntu 8.04 and, after
chasing a lot of dependencies and fighting a few problems I was succesful.

I wanted to share some of the problems because I'm not really sure if
the problems are in the code or in my machine.

One of the problems was in renderjob.cpp, the compiler kept telling me
that stderr, fprintf, exit and something else I can't remember were
indefined.

With this patch I was able to compile that part:

I stumbled across an error in kthumb.cpp, telling me that tostring in a
kurl was private, and looking in kurl.h it suggested to use the method
url():

+        m_clipManager->setThumbsProgress(m_url.url(), p->value());
~     }
~ }

The last error I had is something that I don't know if it could be a
problem in the future. Ubuntu 8.04 ships with Qt 4.3, and clipitem.cpp
have calls to QPainterPath::addRoundedRect, which doesn't exist in QT
4.3, but in 4.4.
In Qt 4.3 it is addRoundRect, so I had to reflect that in the code to be
able to compile it.

Unfortunately, after compiling, the first thing it does is crash on me
at start, just after it asks me to say the location of inigo:

Looks like it crashes doing Mlt::Factory::init(), maybe is something in
mlt or my kde installation?
