Running an external code for fpga target

Hello,

     I want to run a dll file from a c++ code within the fpga target of a single board rio, but when i press the run button of the fpga vi (the vi which contains the call library function node) 5 target specific errors and warnings are displayed. The first error is Call Library Function Node 'Solar Position Algorithm.dll:spa_calculate': Node not supported in current target 

Please I want a solution for this error

thanks
