Which version of gcc are you using?

[Comment 2 Denis Knauf 2005-04-29 09:23:57 UTC]

i've forgotten: i use gcc-4.0.0!


i think, this should be a possible way: i don't know, because there's a new error.

i don't know, if this is the right way, because, it was a static var.

I'll take care of this tonight.

[Comment 4 Diego Elio Pettenò (RETIRED) 2005-05-01 11:49:42 UTC]

Ok I have a patch to fix vidix compilation, but seems not to work here.

If you don't need vidix, disable it to fix the bug.

[Comment 5 Denis Knauf 2005-05-01 23:58:11 UTC]

the second error isn't vidix! it's libffmpeg/libavcodec.

[Comment 6 Diego Elio Pettenò (RETIRED) 2005-05-02 00:47:58 UTC]

For ffmpeg just use the external one, fixing it for gcc4 would be an overkill (and next xine would probably use a more recent ffmpeg already fixed).

[Comment 7 Diego Elio Pettenò (RETIRED) 2005-05-06 18:55:04 UTC]

Fixed in CVS the vidix error.

ffmpeg is a WONTFIX as upstream is updating internal ffmpeg. Just use the external one in the mean time.
