[mythtv] Compiling for DirectFB/Qt-Embedded

[Simeon Walker]

Hello,

Since I just can't get X working properly on my G400 DH I thought I 
would have a go at compiling mythtv to sue the DirectFB output. I am 
using mythtv from CVS as of 10am 5/1/2004, DirectFB 0.9.20 and  
qt-embedded-free-3.3.0b1.

I built qt-embedded as mentioned here:
http://mythtv.org/pipermail/mythtv-dev/2003-December/017130.html

I have read the previous emails on this topic. First, I have found that 
I have to add:
DEFINES += QWS
to my settings.pro to prevent some X11 related stuff from being included.

Then I found that all my generated Makefiles refer to -lqt-mt whereas 
building qt-embedded produced libqte-mt. My QTDIR and PATH are set for 
the qt-embedded build directory and only that version of qmake can be 
used. A symbolic link helps me get a bit further...

Finally my build fails at this point:

I have tried this on the original 'TV' box, my destop machine at home, 
and finally my machine at work (which get me to the failures quicker!) 
They all run Gentoo with kernels from 2.4.22 to 2.6.1-rc1.

Can anyone see what I'm doing wrong? Is any other version of qt-embedded 
better?

Simeon Walker
