Hi,
while rebuilding stuff for 8.4 i came across pulseaudio. I have fftw
installed and so i expected that pulseaudio will link to it somehow
(as it it mentioned as an optional dep). But it didn't.
The config.log of pulseaudio shows:
...
configure:23251: checking for FFTW
configure:23258: $PKG_CONFIG --exists --print-errors " fftw3f "
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:23261: $? = 1
configure:23275: $PKG_CONFIG --exists --print-errors " fftw3f "
Package fftw3f was not found in the pkg-config search path.

configure:23292: result: no

Indeed, there is no fftw3f.pc, only a /usr/lib/pkgconfig/fftw3.pc
Ideas?

FFTW has three "modes". This requires compiling it three times. See [1].
You need "single precision" for pulse.
https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/fftw
That's interesting. We probably should do that now, but don't we
install single precision with the current instructions?
Checking...
Pulse is looking for ffttw3f...
fftw is now installing :
libfftw3.so.3.5.8
libfftw3.so.3
libfftw3.so
OK, the default for fftw is double...
I'll fix the fftw instructions.
