[mythtv] Compiling for DirectFB/Qt-Embedded

[Derek Watson]

Hi Simeon

I've also been trying to get this to compile without much success. Looks 
like you might have solved my problem being the exclusion of lame + 
freetype.

To overcome the problem you describe here I went looking at the qt-embedded 
ebuild under the src_install function in the script (located at 
/usr/portage/x11-libs/qt-embedded/qt-embedded-3.1.2.ebuild). From this 
you'll see that the file 
/usr/portage/x11-libs/qt-embedded/files/47qt-embedded3 is copied into 
/etc/env-d which in turn updates ld.so.conf when env-update is run. You need 
to copy this file in and update to reflect the paths to your src dir if 
you're using that as your qte base and run env-update.

Not sure if you need to ldconfig after this but try that if it still doesn't 
work. Good luck!

Derek.
