I am developing an Audio Unit and I need to use the fourier transorm for some DSP. The open-source FFTW3 seemed to me a good choice, but I'm having some troubles with it.

The first time that I installed it, I didnt' know that I had to specify my system architecture (I'm working with a macbook pro, so it is i386) during the configure step. When I wrote a simple test program, the compiler returned no errors, but the buffer that had to contain the fourier transform of a test signal remained empty.

Then I looked at the mailing list and I found some suggestions on how to configure the installation of FFTW3 in this thread: http://lists.apple.com/archives/xcode-users/2007/Apr/msg00127.html

So, I decided to install again cleaning all the old files and using the configure options described in the mentioned thread.

Now I can't even link properly the libraries with my code (I tried with the universal binary one generated by the command -lipo and the one specific for my architecture libfftw3f-i386.a).

In addition, when I try to jump to the definition of an object belonging to a type defined in a fftw3 header, XCode crashes. It crashes also when I access directly the fftw3.h header.

Does anyone have some hints?

Thank you.

Daniele.
