gtk in snd?
Matti,
On my Mac-Systems Fftw is only recognised when the port fftw-single is installed:
sudo port install fftw-single
One needs to specify the Architecture to get rid of the X-error:
This works for me:
./configure -prefix=/opt/snd-s7 CFLAGS="-arch x86_64 -I/opt/X11/include" LDFLAGS="-L/opt/X11/lib -lmx -bind_at_load" -with-gsl -with-gtk -with-s7
I personally cannot recommend to work with it on macOS anymore, due to increasing audio-latency and fading X11-support. On macOS Big Sur I’ll use it in a virtual Linux-machine, so I won’t have to mess with homebrew and Macports.
All the best,
Daniel

I got only GTK to run. So I would be happy if the solution you will find could work on OSX without having a good recommendation for a specific system myself.
