go to the gumstix_buildroot directory, then do

make menuconfig

go to

"package selections for the target"

key down to libao, libmad, madplay, etc.
select the ones you want

then exit and type

make

move the modules over or reflash your gumstix.  and the modules should show up in /lib.  they were transferred automagically when i reflashed my gumstix.

if they dont get transferred in the flash image, or you wanna just send them over manually, try looking in build_arm_nofpu/root/lib/ for libao.so.* or look in build_arm_nofpu/LIBRARY_NAME_x.xx.x/.libs

you can always do a find -name libao* in the build_arm_nofpu directory if you can't find them.

libao sounds like a nice library to use for sound playback.
I didn't see it in my lib dir on the gumstix though, or in the gumstix-buildroot dir.
 
Do I need to add it manually?
