Dear all,

I have encountered a problem when installing the Swi-prolog in Raspberry Pi2. 

I followed the instructions from http://jlcreations.com/swi-prolog-raspberry-pi/ to install the Swi-prolog in Pi. However, there is an error of "undefined reference error". Enclosed with the screenshot of the configuration file. Looking forward to have some suggestions. Thanks.
