错误，使用MPLAB IDE编译程序时出现的错误
碰到了这个错误，不知道如何解决，有人遇到过没？
Executing: "C:\Program Files\Microchip\MPLAB C32 Suite\bin\pic32-gcc.exe" -mprocessor=32MX460F512L -x c -c "D:\isr\hs_ir.c" -o"hs_ir.o" -MMD -MF"hs_ir.d" -D__DEBUG -g
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp/ccoTHVTd.s: Assembler messages:
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.
[解决办法]
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
[解决办法]
symbol `__vector_dispatch_7' is already defined，应该是这个被重复定义了
[解决办法]
检查一下你的程序有没有重复定义的变量
