SDK example from Xilinx do not compile

Hello, I have been trying to implement the SDK example
(http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/edk_c...)
into my Avnet Virtex 5 FXT Eval Kit... but the program gives an error...

Is there any way of searching a word inside the whole project in order to
