[Dev-C++] Re: newbie: trying to install FFTW library on XP

Siva:

Thanks for your help, and I did as you suggested, and tried compiling the
tutorial code...but I'm getting an error I don't quite understand:

invalid conversion from `void*' to `double (*)[2]'

this appears at the two lines with fftw_malloc(lines starred in my code below)
here's the exact code I'm trying to compile...and I already put the header in
the include folder and linked the .lib file.  If you or anyone else had any
ideas why this would happen, I'd appreciate it thanks.

#include <stdlib.h>
#include <fftw3.h>

int main()
{
    int N = 256;
    fftw_complex *in, *out;
    fftw_plan p;
*    in = fftw_malloc(sizeof(fftw_complex) * N);
*    out = fftw_malloc(sizeof(fftw_complex) * N);
    p = fftw_plan_dft_1d(N, in, out, FFTW_FORWARD, FFTW_ESTIMATE);
    fftw_execute(p); /* repeat as needed */
    fftw_destroy_plan(p);
    fftw_free(in); fftw_free(out);
    system("PAUSE");
    return 0;
}
