XCore Exchange

I want to use uart_lib which i already download via libraries column in xmos software.
first i created one fresh project and paste one example code and add resources of lib_uart.
Even i can't use this library for execute my code.
Pls help me out.
Thank you.

I found the solution of this problem.
Go to project and select makefile and select depended library/libraries (must download and open while selection) select and close project.
Start Build it. Thank you.
