VGU on Mesa 9.0

Hi all,

I'm a newbie here, nice to meet you all.

Currently I'm working on a OpenVG app. I've tried writing some little 
code with Mesa implementations, still have yet to get any results (I'm 
learning how to use OpenVG anyway).

I've tried calling functions in vgu.h, says vguLine(). It compiles but 
failed to link, with symbol not found error. Furthermore I've checked 
the symbol insides libOpenVG.so, and none of symbols inside start with 
vgu. I've even go further by compiling Mesa 9.0.1 myself (9.0 does not 
compile). Still failed to link. I saw that 
src/gallium/state_trackers/vega/vgu.c is already compiled, but I don't 
know what file contains the binary from that file.

My question is do I need another shared object file for vgu ? Or did I 
do any mistakes linking/compiling these ?

Thank you.
