Enable udev and speex support for pulseaudio

Question

I tried to install pulse audio, but after running ./configure I got a warning message:

===== WARNING WARNING WARNING WARNING WARNING WARNING WARNING =====
You do not have udev support enabled. It is strongly recommended
that you enable udev support if your platform supports it as it is
the primary method used to detect hardware audio devices (on Linux)
and is thus a critical part of PulseAudio on that platform.
===== WARNING WARNING WARNING WARNING WARNING WARNING WARNING =====


===== WARNING WARNING WARNING WARNING WARNING WARNING WARNING =====
You do not have speex support enabled. It is strongly recommended
that you enable speex support if your platform supports it as it is
the primary method used for audio resampling and is thus a critical
part of PulseAudio on that platform.
===== WARNING WARNING WARNING WARNING WARNING WARNING WARNING =====

I tried to find information about enabling these two services, but I couldn't find anything. How can I enable them?

Answer 1

These are not services, but compile options, use ./configure --enable-XXX to enable them (see ./configure --help first)

Also, to alter compile options for debian based distros, consider the debian way,

First use apt-get source XXX to fetch the source code, and use apt-get build-dep XXX to install dependencies,

Afterwards, change the debian/control file (which contains compile option),

Then at the top source folder, launch dpkg-buildpackage, when succeed, you'd see a few deb packages outside that folder, use dpkg -i XXX.deb to install it.
