by First Error, the configure should be like this:
./configure --host=arm-apple-darwin --target=arm-apple-darwin --enable-float
( without --enable-neon ) and the second Error, its because the libraries are all from the arch x86_64. they should have the right architecture ( libfftw3f_i386.a should have the arch. i386.a and libfftw3f_armv7s.a the arch. armv7s.a and so on )
i could make the right library for FFTW by using macports (or u can use homebrew) to install a universal build of the library for use with OpenFrameworks.
type this into a terminal window:
sudo port install fftw-3 +universal
the port install command will place the fftw3.h header file in your_HD/opt/local/include folder, and the libfftw3.a library in your_HD/opt/local/lib folder. To use the library in your OF project, add these two files to your project via the menu option Project -> Add to project...
thanks for every help and special thanks @Adam Freeman
