Confirmed for another G4.
Created attachment 76500 [details, diff] Fixes OSX style altivec vectors This patch fixes the OSX style altivec vectors that were causing the breakage above. However, I ran into another issue after fixing this, the gcc attribute "always_inline" in altivec.h is screwing up and the compile fails. I can't see why, but it's probably because it's too late at night. :)
Thanks for the patch! To solve inline problem I edited the file /usr/lib/gcc/powerpc-unknown-linux-gnu/3.4.4/include/altivec.h and removed all the "__attribute__ ((always_inline))" definitions in the "Prototypes for builtins that take literals" section. Now avidemux compiles and works well.As to the above change, I don't know how it will influence the overall system performance or future compilation...
This bug should not be closed, it's still broken in the portage tree. I'm glad it worked for you, but that's not a good solution to the problem and may cause other issues in the future.
Created attachment 91244 [details, diff] Final patch, fixes gcc-4 breakage and the altivec issues
Committed to cvs. We need to consider this version for stable as well since 2.0.24 isn't ported to modular X yet. :p
