[MPlayer-dev-eng] Altivec (again..),G3 and runtime detection..

[Gustav Axelsson]

I can try it on my iBook G3 but how do I compile it? I think I have  
downloaded the files properly using
I tried ./configure and then make but make fails and the compile is  
aborted on line 150 of swscale_internal.c

In file included from swscale.c:72:
swscale_internal.h:150: error: parse error before "vector"
swscale_internal.h:150: warning: no semicolon at end of struct or union
swscale_internal.h:151: error: syntax error before "signed"
swscale_internal.h:152: error: syntax error before "signed"
swscale_internal.h:153: error: syntax error before "signed"
swscale_internal.h:154: error: syntax error before "signed"

swscale_internal.h:156: error: syntax error before "unsigned"
swscale_internal.h:160: error: parse error before '}' token
swscale_internal.h:160: warning: data definition has no type or  
storage class
swscale_internal.h:163: error: parse error before '*' token
swscale_internal.h:164: error: parse error before '*' token
swscale.c:576: error: parse error before '*' token
swscale.c: In function `yuv2packedXinC':

and it goes on and on for like 100 more rows with errors and warnings  
in swscale.c, swscale_template.c and swscale_altivec_template.c

Is this because I have the wrong compiler (3.3) or is it something  
else that's missing?
I've tried the MPlayer v1.0pre7 source and the daily CVS snapshot  
source from the homepage but I cannot compile any of them :-(

I'm on Tiger, 10.4 with xcode installed.

Sorry if my questions are a bit stupid, I have only used fink before.
