That's a valid point.
Well, then i suggest to remove the waf '--universal' option instead of
fixing it. In its current state it is broken.

Does it really? It's just add a handful compiler and linker flags.
What difference does it make to ardour: it is less than 10 lines in the
ardour build-env and code; incl. the FPU #ifdefs. It's more of a

To get a 64bit native binary.
My OSX machine is full of LV2 and LADSPA plugins: only a handful AU
plugins that I never use. The only thing that prevents Ardour from being
a 64bit binary is the Carbon AU plugin interface. Now, I don't expect a
magic speedup - audio processing is 32 bit anyway - but it may give an
edge to GUI responsiveness.

this afternoon.. wanna take a bet if a wallclock will suffice to
quantify the difference between 32 and 64bit? :-)

What version of OSX do you build it on? What compiler?
I guess the Carbon headers are pulled in automatically via the 10.4u SDK
that you're using on your box. Xcode on OSX 10.6,7 does no longer come
with the 10.4 SDK.
I think it can be explained like this:
The CoreFoundation.h header that is included from audio_unit.cc uses the
_Cocoa_ API these days (getCFRunLoop(), CFRunLoopGetCurrent() etc.).
GetCurrentEventLoop() is part of the _Carbon_ Event Manager. You need to
explicitly include Carbon headers and link to the Carbon Framework on
"Use the getCFRunLoop method of NSRunLoop to obtain the corresponding
CFRunLoopRef type. In Carbon applications, use the
