| Post subject: | lame with AltiVec support |
i tried to build lame-3.98.4 with AltiVec support using this patch: Code:
i compiled it with success on my CRUX PPC 2.6 (32bit) with the following steps:Code:
patch -p0 -i $SRC/lame-3.98.4-altivec-20100323.diff
but the resulting binary segfaults on my G4 cpu based machine.export CONFIG_DEFS="-maltivec -DALTIVEC" ./configure --prefix=/usr --mandir=/usr/man \ --disable-nls --with-gnu-ld \ --disable-analyzer-hooks --disable-gtktest \ --enable-all-float On the contrary when i compile it on my 64bit (still CRUX PPC)with: Code:
export CONFIG_DEFS="-maltivec -DALTIVEC -DALTIVEC_970"
it works like a charm on my G5 with great speed improvement.Is there someone that have success on G4 machines? Some AltiVec guru around to give me some tips? ## EDIT ## my toolchain: binutils-2.20, gcc-4.4.5 and glibc-2.11.2 |
