C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp/ccoTHVTd.s:2779: Error: symbol `__vector_dispatch_7' is already defined
Halting build on first failure as requested.
----------------------------------
Debug build of project `d:\isr\test.mcp' failed.


------解决方案--------------------
Error: symbol `__vector_dispatch_7' is already defined,说你的`__vector_dispatch_7' 已经定义过了,或者你找个简单的程序,试试看还有没提示错误
------解决方案--------------------
symbol `__vector_dispatch_7' is already defined,应该是这个被重复定义了
------解决方案--------------------
检查一下你的程序有没有重复定义的变量
------解决方案--------------------
