Henry,

I just noticed the reply you made to a post a I made a couple weeks ago
about the slowness of IDL's fft. I have spent quite some time figuring out
how to create a fftw3 dll and just suceeded at that yesterday. I was about
to spent quite a bit of time writing an extensive DLM and I saw that you
posted that very thing! So you saved me quite a bit of work. I noticed your
DLM has provisions for threads. Is that an altivec thing? I am wondering if
your DLM will work transparently with my win32 dll. Though when I build the
dll, I did not specify multithreading in the config.h file. Also, how did
you combine the double and float functions? On windows, I suppose I would
create 2 static libraries (float and double) and then link them into one
overall dll?

thanks,

brian
