Well, this is a bug. And it is not a bug. :-)
It is not a bug, only some nitpicking compiler complaining (its a

warning after all) about a non-virtual destructor which wouldn't get

called. But sinced it is an empty destructor this isn't a bug.

It is a bug, because I did not disable all the debugging code (-Wall

-Werror) before releasing the thing. Maybe I will do a 0.3.1 in a few

days that fixes these little things.

Why do you need extraincludes and libdir? for qt you should use qtlibs

and qtincludes. Everything else is (should be?) handled by pkg-config.
Please try again with just calling "scons configure && scons".

No, because aclocal is from autoconf (ac = autoconf) and I am not

using auto* anymore. So while other apps might probably be broken now

(don't drink and su!), JackMix should build just fine :-)

Wenn man mit Raubkopien Bands wie Brosis oder Britney Spears wirklich

einen Sack Rohlinge kaufen.
