GCC 3.0 changed the ABI, and I believe 3.2 did as well. Then again, I
mostly use C, so it hasn't bothered me much. One way to do it is leave
qt2 at the old version for older programs, and compile qt3 with the new
gcc; that is how debian is handling it (if gnuradio can use qt3; I don't
know, I haven't looked at it that hard).

In any case, you may save time by upgrading your distro, depending on
how much you have customized it.

R C

P.S.
My current project is AFSK1200 on an AVR, which is much easier than what
you folks are doing :) I've got transmit working, but receive needs some
DSP and thus a part with a hardware multiplier. :)
