Errors when compiling

Hi all,

I am using the template project from SDK to do my programming. After a whole night debugging, I still have two errors left. Could you please help me to figure out what those are? 

1. Error	1	error LNK2019: unresolved external symbol __Znaj referenced in function __Z5runSWv	SW2D.obj
2. Error	2	fatal error LNK1120: 1 unresolved externals	../../bin/win32/Debug/SW2D.exe
