Subject: can't compile 2.6.11-rc2 on sparc64

I get this error :

gcc is 3.4, 64bit. That's ultra5.

Please look for another error. Run 'make' again.
Those are all just warnings and don't cause a build error.

I have no idea what causes error here. What shall I input to get more info
about that error ?

It's the '-Werror' option that makes warnings become fatal
errors that is stopping you here. You could edit
arch/sparc64/kernel/Makefile and remove/comment that for now.

Thanks, I didn't noticed that.
Have built only x86_74 and i386 archs before, these don't use -Wall I guess.
(too many warnings on different signess comparation, btw, IMO security
problem - might be in the future).

All architectures use -Wall.
