[PD] constantq~ - Thomas Grill

[Dan Wilcox via Pd-list]

To save time and further headache, the brew command would be:

    brew install fftw --enable-sse2 --universal

This will give you fftw compiled as a fat 32 & 64 bit library.

I just tried it and double checked with lipo:

    $ lipo -info /usr/local/Cellar/fftw/3.3.4/lib/libfftw3.3.dylib 
    Architectures in the fat file: /usr/local/Cellar/fftw/3.3.4/lib/libfftw3.3.dylib are: i386 x86_64

For future reference, the --universal brew command works with almost all formulas.

My processor is Intel Core i7, so according to Apple that is 64 bit. Related: since Thomas suggested I should do "single precision" installation, I used "brew install fftw --enable-sse2" which I thought enables single precision according to https://github.com/Homebrew/homebrew/blob/master/Library/Formula/fftw.rb . When that didn't work I uninstalled and just used "brew install fftw", with same results. Terminal session of this attached.
