monkey c api

[wbtlb]

Hi, could you please provide more example to show me how can I use monkey C api. I try to compile hello.c, I get an error:

Building the examples. 

The build expects the library to be installed,
to work as closely as possible like an external app.

Package monkey was not found in the pkg-config search path.
Perhaps you should add the directory containing `monkey.pc'
to the PKG_CONFIG_PATH environment variable
No package 'monkey' found
cc -Wall -c -o hello.o hello.c
hello.c:20:23: fatal error: libmonkey.h: No such file or directory
#include <libmonkey.h>
^
compilation terminated.
make: *** [hello.o] Error 1

I can't find libmonkey.h any where. Please help me.
