[mythtvnz] Fwd: [mythtv] New Video Decode and Presentation API

[Dylan Hall]

I hit the same error.

I tried to build it on my gentoo box but I got the error below because
I'd not installed the 180.06 nvidia drivers yet. I think the error
relates to the final linking stage against the new drivers. The gentoo
box is using gcc 4.1.2 so it should have compiled.

I decided I didn't want to break my media pc by frobbing with the video
driver so I repeated the process on my ubuntu 8.10 laptop (both boxes
have an nvidia 8400 of some description).  I installed the latest nvidia
driver but also failed to get the mplayer + patches to compile.  I'm not
sure if it failed to compile because of an issue with the driver
installation or because of the version of the compiler.

I then tried to remove the new driver and go back to the package manager
installed driver which took me a couple hours of swearing and broken
X... 

My advise to people would be to wait a couple of months while they iron
out some of the teething problems.  I spent 3-4 hours and have very
little to show for it :(
