I'm currently trying to build the mythtv cvs version on AMD64 system pure64 (Debian alioth)
gcc is 3.3
I apt-get'ed libqt3-mt-dev libmysqlclient10-dev liblircclient-dev
libartsc0-dev liblame0 liblame-dev
$PATH and $QTDIR points respectively to :$PATH:/usr/share/qt3/bin and /usr/share/qt3
When I try to make mythtv cvs I get an "unrecognizable insn" error: (see below)
Figuera:/usr/local/cvs/mythtv/mythtv# ./configure
Please note that these settings only deal with libavcodec, not MythTV.
CPU x86_64
Big Endian no
MMX enabled yes
Vector Builtins no
Creating config.mak and config.h
config.h is unchanged

Maybe the fact that my system is pure64 could explain the problem? I prefer to ask here before initiating a bug report on gcc.
I initially built mythtv-cvs on a PIII-450 and was pretty amazed with the results. This made me decide to go for a whole new config with AMD64, which was supposed to be well supported by MythTV (apart from some Mythmusic issue).
I've spent the whole week-end trying to figure it out before resulting myself to post here and ask for some help.
May I add I'm eager to test/validate the whole thing on my architecture (Asus K8N-E Deluxe, PVR350) and help the mythtv community. Still I first have to make it work :)
Thanks
Eric

Any idea/ressource to point me to?
I tried to build the 0.16 sources, and ran into the kind of trouble (unrecognizable insn, this time in generictree.cpp file)
Should I consider submitting a bug to gcc/Debian gcc? Many people seem to build AMD64 flawlessly... Did anyone succed on a Debian pure64 system?
