unable to use audio_example.c

Fresh Tulip
Hello,

I have Kubuntu 8.04 (KDE 4 Remix) installed. I downloaded latest gstreamer source from CVS and have built and installed using the following options:

configure --disable-static --disable-nls --disable-loadsave --enable-debug=yes --enable-gst-debug=yes --enable-binary-registry --enable-gtk-doc

I am able to write test application (in c) and play a wav file fine.

But when I try to compile audio_example.c, I am running into following linker issue.. any ideas why?

gcc -Wall $(pkg-config --cflags --libs gstreamer-0.10) audio_example.c -o audio_example
/tmp/ccE2lsav.o: In function `main':
audio_example.c:(.text+0x58): undefined reference to `gst_controller_init'

GstController is in a separate helper library, try with

 pkg-config --cflags --libs gstreamer-0.10 gstreamer-controller-0.10
