What does "usage of altivec is not implemented"? In supecollider, or in the compiler? In any case, perhaps the solution is to disable supernova in ppc64el as well instead of adding custom flags. > > While at it, Konstantinos also went ahead and fixed it for ppc32.

I presume the upstream code works on apple platforms, is that an important difference? The second part is adding -mabi=altivec and -maltivec, which is unfortunately not possible, because that would contaminate the rest of the binaries with altivec code. AFAIK, debian still supports non-altivec machines. (supernova requires altivec, but for other machines we have scsynth). Perhaps a more correct patch would alter the logic in external_libraries/nova-simd/CMakeLists.txt to allow passing the required flags just to nova-simd. -- Saludos, Felipe Sateler _______________________________________________ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-multimedia-maintainers
