Thanks for the info, this is indeed a bug. I will have it fixed in the next upload in the next few hours. > Furthermore, it means that 32-bit packages are not > built with MMX or SSE2 support, despite every single CPU the last ten years > (and certainly every CPU anyone would want to decode DVB-CSA on) has supported > SSE2. (MMX was added in 1997!) According to Debian's architecture baseline ( https://wiki.debian.org/ArchitectureSpecificsMemo ), MMX or SSE2 is forbidden for 32-bit i386 build. Debian's "i386" should only support up to i686. I cannot add such build flag. Sorry. > Finally, --enable-altivec should probably be enabled on appropriate CPUs. According to Debian's architecture baseline ( https://wiki.debian.org/ArchitectureSpecificsMemo ), altivec is not guaranteed on any architecture. I cannot add such build flag. Sorry. Thanks, Boyuan Yang
