Compiling XBMC on Fedora 11 beta (rawhide)

im not sure if it will make any difference, but you could also try removing ccache.

It's a bug in gcc 4.4. The functions need double-cast to work around it, but I'll be damned if I could figure it out debugging via proxy on IRC. I won't be installing 4.4 just to get this straight for the nerd circle jerk distro.

Call it what you like, in 5 months Ubuntu 9.10 will also ship 4.4

In which case it won't be for "just the nerd circle jerk distro"

Al/motd2k: I'd like to roll this up again. If you could point me to what "double casting a function" exactly means i'm willing to do the dirty work of hacking that file until it compiles with gcc 4.4.

I'm no newbie to programming but my C/C++ skills are simply not that good. From what i understand is, that some of those functions who get exported need an additional tweak. They're all casted to (void*), so what would the second cast be? I read the bugreport about that 4.4 regression and some guys came up with a second cast into the class where the function is defined. What's that in xbmc-source-speak?

Thanks for all you help, i'm really willing to understand more of this...

tried it with the svn tip right now, same errors. I've had gcc 4.4 ever since it was in testing, and I have managed to compile xbmc with gcc 4.4 before, though it is quite possible that make was picking up stuff from ccache then.

Just google the error gcc spits you. There are plenty of mailing list posts about it.

Yeah exactly the same for me. Sorry for pointing you in the wrong direction. After removing ccache i also hit this issue.

I did, otherwise i wouldn't even know about that double cast thingy. Unfortunately i found no further useful infos, at least none that's xbmc specific. If you say double cast, then what would the second cast be? i doubt it's also (void*)

EDIT: Forget it. I'm seriosly dumb, blind or both. The exact error message lead me to something actually useful - and i'm SURE that was not there yesterday

Update: I have managed to come up with a patch which fixes these issues.
It's attached here: http://trac.xbmc.org/ticket/6627

Maybe a dev will approve and commit it to the main branch.
