[mythtv] qt3 vs qt4

Thanks for the reply.

Running ubuntu in mind.  I've found no need to have any freetype2 
libraries installed for it to compile correctly.  I'm not sure what 
purpose libqt3-mt-mysql serves either.  I also haven't need 
xserver-xorg-dev in order to compile.  I'm trying not to install extra 
packages that I don't need since when the compiling finishes I have the 
following problem.

I build the program then run make install.  Then on the mythtv box I 
can't run mythtv-setup or mythfrontend.  I get a floating point 
exception.  The wierd thing is that I can run both those programs over 
an xsession to my laptop without any problems albeit fairly slowly over 
my wireless.  I build everything over ssh from my laptop (don't think 
this matters) since just the TV is hooked up to the mythbox.

So I'm thinking I'm missing some dependencies/runtime required libraries 
on the mythbox that I have on the laptop which is causing the floating 
point exception on the mythbox.  I'm really out of ideas.  If someone 
could install my compiled mythtv installation (I'll supply some .debs) 
and get back to me that would be great.  I'm just not sure where I'm 
going wrong.
