Issue or even a problem with current release

Hello!
On a whim I decided to download the currently available release for
GNURadio. It complained that I needed the FFT package. I promptly
found it at its location and built it, and installed it. The configure
script still says that below my signature, even though I’ve moved
everything over to the /usr/lib location. Having never really worked
with pkg-config scripts, I am at a loss here.

checking for fftw3f >= 3.0… Package fftw3f was not found in the
pkg-config search path. Perhaps you should add the directory
containing `fftw3f.pc’ to the PKG_CONFIG_PATH environment variable No
package ‘fftw3f’ found
configure: error: Library requirements (fftw3f >= 3.0) not met;
consider adjusting the PKG_CONFIG_PATH environment variable if your
libraries are in a nonstandard prefix so pkg-config can find them.

When manually building FFTW, you need to add --enable-float to build the
single precision version of the library.

Most systems/distributions have already packaged FFTW this way, so you
could try installing binaries from whatever system or distribution you
are using.

Please take a look at:

http://gnuradio.org/trac/wiki/BuildGuide

…for instructions suitable to your particular situation.

You probably didn’t install a package that contained the
single-precision floating point version of FFTW.

You didn’t say which OS and/or distribution you were using.
It’s easy to build FFTW from source, see the top-level README in
gnuradio.

Hello!
I did not say, because its come up before in this group. I am indeed
building on Linux. The name is Slackware Linux. And yes I did build
the FFT kit from source from their site.

I suspect that since my distribution is not as well known as it should
be, it may not be listed in your build guide, but I’ll take a look
there.

Are there any more “gotchas” I should be aware of?

Hello!
Folks I now know what is wrong and why the configuration script can’t
find what it thinks it is looking for. Basically I have fftw3.pc in
the usual place for these files, and the script is looking for
fftw3f(.pc). (I added the .pc in these things ( ) so that we’d have
some sort of constant indicator there.

Now where do I change this in the files that the configuration script
calls upon to ascertain what its looking for, and how to work with it?
You can’t just change that. As someone said previously, you need to
build fftw with the --enable-float option. Please see:

Doesn’t the group track the development of everything related to our
project?

Hello!
And now a new problem. I found prebuilt packages for jack and
port-audio via a site for my distribution, www.linuxpackages.net and
installed them. However there are still issues. Please see below my
signature. And Matt the previous messages on this thread didn’t bring
to my attention that page on the new site for GNURadio. So I did
rebuild the earlier package that way.

You don’t. You fix the broken installation of fftw on your system.

E.g.,

[[email protected] ~]$ ls -l /usr/local/lib/pkgconfig/
