Hello there!!!
When compiling mplayer on gentoo I get the following error
In file included from imdct.c:757:
imdct_3dnow.h: In function `fft_asmb_3dnow':
imdct_3dnow.h:241: error: can't find a register in class `GENERAL_REGS' while reloading `asm'

Am I missing something or what??
Any ideas, any help is greatly appreciated

Post emerge -pv mplayer

You will need to play with your use flags;

Nopes I have tried everythign on that forum and the links on that forum but I moved from one error to a differente one which try to solve as mentioned in those forums but nothing
Will wait or try somethign else

ere is the new error

I would try to remove the -3dnow flag

What 3dnow flag, I believe I have not set that one...

sorry, looking at the wrong place...
have you posted this on the Gentoo Forums? They are usually very good at solving these kinds over there

I have looked into gentoo forums, and tried everything on those forums, no luck yet, maybe I will wait for the next release
Thanks
