I also get the following error when doing a ./configure on the gr-audio-alsa
package
checking for pkg-config... /usr/bin/pkg-config
checking for alsa >= 0.9... Package alsa was not found in the pkg-config search
path.
Perhaps you should add the directory containing `alsa.pc'
to the PKG_CONFIG_PATH environment variable
No package 'alsa' found
and search as I might for alsa.pc I cannot find it anywhere on the system never
mind set an environmental variable.
regards
Tom

Thank you Eric. I am using Fedora 3 on a PC trying to compile the core. That
worked (compiling single precision for the FFTW library). So it got through the
.configure stage. Then when I make the core
it does tests... it passed the codec test ok and the next 59 tests it then said
Pass: test-all
However, after that it comes up with loads of errors (all the same one repeated
at different stages). Here is one of them
----------------------------------------------
make[5]: Entering directory
`/root/Desktop/soft/gnuradio-temp/gnuradio-core/src/ python/gnuradio/gr'

and this last error 'cannot find import name buffer' appears again and again.
any ideas?

Tom and everybody else: When reporting a problem *please* at a minimum
report your operating system, architecture, distribution and version.
Keeps me from having to try to read your mind...
My guess would be that the version of FFTW you installed did not have
the single precision library built and/or installed. Not sure of your
distribution, but if you build fftw from source, these are the
configure options you want:
$ ./configure --enable-single --enable-shared [ and perhaps --enable-sse or
--enable-3dnow ]
