Doesn't above mean that if the compiler host supports altivec then the
compiled binary won't work without altivec?
Yes and no. ffmpeg builds two different flavors on powerpc, one that is
configured with --enable altivec and gets installed into
/usr/lib/altivec and another one configured --without-altivec and gets
installed to /usr/lib.
/lib/ld-linux.so queries the kernel for hardware capabilities and sets
the .so search path appropriately.
Cool!
thanks for the explanation. :-)
