I don't know the particular problem there, but if you send me the source, I could try adding it to Pd-extended and building it with MinGW.
Also, there is a patch to make Pd itself use FFTW3. It looks pretty straightforward to apply and compile, but I haven't tried it.

Hi All!
I have a very interesting external "partconv~" that performs a realtime blocked convolution. partconv~ uses fftw3.
Changing from PD 0.37 to PD 0.39 (Windows XP) the new PD reports "could not load partconv~.dll". I started debugging the external. everything works fine until the point a function from the library fftw3.lib is linked into the dll. In the code I just call a function of fftw3.lib at a spot the program execution never reaches. if I do so PD fails loading the external. If the function call is removed PD loads the dll and everything is fine. this little test shows that there seems to be a linker problem, probably a naming conflict or something similar. yet, neither linker nor compiler report errors at any time.
Q: Has someone partconv~ or a fftw3 based application running within PD0.39, Windows ?
Has someone discovered similar problems?
Is there a programming trick to get more infos or even get the thing running ?
THX a lot!
