问题
A similar version of this question has been asked before (how to compile fftw3 on iOS) about previous versions of IOS and/or OSX, but I am unable to get fftw3 working on a actual IOS device. (Though it works fine in the simulator using the MacPorts "universal" distribution). If anyone has had any success using fftw3 please let me know how you were able to get it working! I am using OSX 10.7 and am trying specifically to run fftw on an iPad3 with IOS 5.1 installed. Thanks.
