I'm not sure if I do. ;) Never used the debian symbol files... > Another source of problem is that presence of machine optimization.

I haven't checked, yet, but I have a Debian 486 machine around, so I could try it. ;) Or I disassemble the library and check for SSE instructions. As long as nobody is calling -msse2 with the appropriate arch/cpu definition, no SSE2 enabled code would be compiled.

That's the list each client application relies on. > But is there perhaps a more canonical list? There is doxygen output available: http://jackaudio.org/files/docs/html/index.html Don't know if this qualifies as "more canonical", but this file also refers to the above header files as "the full API" > Moreover, I see some functions marked as JACK_DEPRECATED in jack.h. > Are they still used by applications and does jack2 still provide them? The deprecated functions are still provided and even used by jackd{1,2}'s example clients. ;) This surely needs fixing, but that's upstream's responsibility. I'll file a ticket and provide some patches.
