which MLA is used in your Project ?

which micro controller used ? And i think u have to set first of all in MPLAB IDE project\Select Language Tool Location and
project\Seclect Language Tool Suit . correctly and then After project\Build Option\Project in Directory Tab u have to add include search path and library search path .

and then after build . also i have same issue in my Pic32 device MLA used in first time .

and give me some more information of your main code here .
