Installation problem CentOS ... FFTW3F

GNU Radio
1

Hi,
I have a problem installing gnuradio on Centos-5. I installed fftw-3.2.2
and
ran the configure script in gnuradio. It shows this error as it cant
find
the fftw3f.

ecking for FFTW3F… configure: error: Package requirements (fftw3f >=
3.0)
were not met:

No package ‘fftw3f’ found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables FFTW3F_CFLAGS
and FFTW3F_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I then set the PKG_CONFIG_PATH as /usr/local/share/fftw-3.2.2 as this is
where the fftw package is. I even tried setting the FFTW3F_CFLAGS and
FFTW3F_LIBS as
/usr/local/include/ and /usr/local/lib respectively. I still get the
same
error message. A similar post in the forum
http://www.nabble.com/Problem-iinstalling-fftw-3.2-on-Centos-5.2-64-bits-td21909142.htmlwasn’t
of any help either as I still get the same error.

Any help will be appreciated. Installation in Ubuntu is so much easier
but I
don’t have an Ubuntu system now and will have to work on a CentOS
machine.
Please help.

Thanks,
Mir

Try installing the -devel package.

I followed the instructions given in
http://gnuradio.org/trac/wiki/FFTWInstall but still had no success.
Eric,
suggested installing the fftw-devel package. I used the source
fftw-3.2.2
and wouldn’t this be all I need. The PKG_CONFIG_PATH was set too but
still
had no success.

The output of pkg-config is shown below and it shows that fftw is
installed.
$ pkg-config --list-all | grep fft
fftw3 FFTW - fast Fourier transform library

Gnuradio’s configure doesn’t seem to find it. What can I do now?

Thanks,
Mir

Please post the corresponding output of configure and the correpsonding
lines of configure.log. Maybe we can find the error with more
information.

Note it is looking for fftw3f - not fftw3.
