Hi all, Here is my answer to Derek about FFTW, if some people are interested... Hi Derek, In fact, we designed a set of wrapper functions to hide the fftw particular calls. This is probably not what you wanted to hear but I can give you some advices nevertheless. I had to include a big set of C files into ROOT, for my project. The point is that rootcint has some problems with C. I used bare cint to do the job (look at the MAKECINT utility), i.e. produce the dictionnary files from the C headers. The trick is to make it think that the code is C++ and perhaps wrap the headers in extern "C" { <the header> } Tell me if you have problems Cheers Damir Rene Brun wrote: > > Hi Derek, > > There was a discussion recently on roottalk about FFTs (see archive). > > If you want to make an interactive interface to an old library (C or f77), > you can read the instructions at > > http://root.cern.ch/root/HowtoCERNLIB.html > > This URL talks about cernlib, but the same recipee can be used > for other libs as well. > > Rene Brun > > Derek M.
