由Atmel Studio 6鏈接器引起的多重定義錯誤

由於多重定義錯誤，我無法編譯Atmel Studio 6.1，這似乎是由鏈接器重複「Libraries/lib_mcu/can/can_isp_protocol引起的。 o Libraries/lib_mcu/can/can_isp_protocol.o「有誰知道它爲什麼會這樣做？以下是編譯器輸出的列表。由Atmel Studio 6鏈接器引起的多重定義錯誤

鏈接器在其命令行上有兩次Libraries/lib_mcu/can/can_isp_protocol.o。由於重複的定義，鏈接失敗。

由於我沒有使用Atmel Studio 6，我無法描述刪除重複的確切步驟。

您可能已將項目添加can_isp_protocol.c兩次。檢查項目中的文件列表。檢查項目選項中的鏈接器設置。
它可能變成了兩倍，以及在（生成/手動創建）Makefile：搜索OBJECTS或OBJS（一般來說搜索can_isp_protocol，不帶擴展名），它看起來是這樣的：

OBJECTS = can_isp_protocol.o can_isp_protocol.o XO喲

對於我的生成（愛特梅爾7）這個錯誤是由冗餘夾雜startup_samd10.c'和'system_samd10的'引起的。在Device_Startup文件夾中。 –
