Your diff unbreaks csound on my PowerBook G4 from 2004. ok gkoehler@ By default, #include <altivec.h> works on powerpc64 and gives this #error on powerpc. One can use "cc -maltivec" to enable altivec on powerpc, but the result would crash on a Mac G3. It is better to disable altivec. Some packages (like xenocara/lib/pixman) can check for altivec at runtime, compile one file with -maltivec, and call that file only if the check is true. I see no such check in csound. --gkoehler > Index: Makefile > =================================================================== > RCS file: /cvs/ports/audio/csound/Makefile,v > retrieving revision 1.4 > diff -u -p -u -p -r1.4 Makefile > --- Makefile 2 Apr 2026 05:31:44 -0000 1.4 > +++ Makefile 7 Apr 2026 09:04:52 -0000 > @@ -44,6 +44,10 @@ LIB_DEPENDS = audio/liblo \ > devel/gettext,-runtime \ > net/curl > > +.if ${MACHINE_ARCH} == "powerpc" > +CFLAGS += -DPFFFT_SIMD_DISABLE > +.endif > + > TEST_ENV = OPCODE7DIR64=${WRKBUILD} > PORTHOME = ${WRKDIR} > >
