Re: [sc-dev] fftw

[Ryan Brown <ryan@xxxxxxxxx>]

Nick,
	I just created a test UGen using fftw and got it compiling. How did  
you add libfftw3.a to your plugin target? You should drag it into the  
Frameworks folder first (not in targets), then once it's there drag  
it into the "Link Binary With Libraries" node for your plugin. I  
don't know what plugin target you used as a template for creating  
yours, but if the target is setup to build universally then you'll  
see those messages unless libfftw if built universally as well. Could  
you include the entire compilation log (after cleaning your target)?

Also, if you just want to mess around without worrying about the  
linking crap, someone packaged up libfftw as a universal framework:

I wouldn't use this in a UGen you give to others though because they  
will have to d/l and install the framework as well.
