Error! FFTW3 version 3 is required but was not found
Use --with-fftw=DIR to specify the FFTW directory tree
Use --with-fftw=no to not use it
Check the README or use configure --help for other libraries needed
(--with-xxxdir = obligatory, --with-xxx = optional (--with-xxx=no to disable))
Huh?
This was version 3.1 I installed of fftw. So whats missing?
Any suugestions?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
You need to build FFTW twice. Once without the "--enable-float" switch and once with. The first builds the libfftw3.a library, the second builds the libfftw3f.a library. This isn't clear from the error message.

I have installed fftw in /usr/local/
/usr/local/include
...
H5FDsec2.h H5public.h fftw3.f hproto.h zconf.h
H5FDsrb.h atom.h fftw3.h htags.h zlib.h
...
/usr/local/lib

libfftw3.a libgsl.so.0.9.0 libhdf5.so.0.0.0 libsz.so
libfftw3.la libgslcblas.a libhdf5_hl.a libsz.so.2

Now I try to build GDL:
./configure --with-fftw=/usr/local --prefix=/usr/local --with-plplot=/usr/local/plplot
