Hm. The 2nd error message usually means "-lpthread" is missing,
during linking.

It builds fine on my fully-updated 64-bit 14.2 box...

Check the file /usr/lib64/pkgconfig/jack.pc and see if has a line
like this:

Libs: -L${libdir} -ljack -lpthread

Also, it's just occurred to me... are you using jack-audio-connection-kit
(AKA jack-0.125.0), or jack2 (AKA jack2-1.9.10)? I just recently took
over maintenance of jack2, but haven't done anything with it yet.
