[PD-dev] myfft~.c:2:10: fatal error: fftw3.h: No such file or directory

[Alexandros Drymonitis]

OK. Well, actually, that's what I'm doing, I'm using mayer_realfft(), 
but I didn't realize it is declared in m_pd.h and that I can use it 
straight away. I now removed the line that included d_fft_fftsg.c and 
the object still works. Thanks for pointing it out. I would still be 
grateful if someone can read the code in my previous message (just 
ignore the third line: #include "pd_fft.h") and see if the analysis and 
resynthesis is done as it should be.
