在 Project 裏的 Library 裏加入 libpPIC24Fxxx-coff.a 的資料庫檔案

其路徑在 C:\Program Files\Microchip\MPLAB C30\lib\PIC24F其路徑在

問一下，以下是我的程式碼。可是一直過不了編譯。
不曉得為什?
錯誤訊息為:
main.o(.text+0x3e): In function `main':
C:\TEST_TEMP\PIC24FJ256GB106_V0.5\main.c:44: undefined reference to `OpenOC1'
Link step failed.

我在Project裡已經加入OpenOC1.C檔案了
不曉得為合還是無法過編譯
