Hi, Francisco Carlos, Thanks for your reply. I do add ifndef in mycode. I have added a lot self-defined fucns before by adding the ifndef-define-endif. BUt this morning, I always suffer from this error. The errors are as follows:
build/X86/mem/cache/lib.o.partial: In function `****': /home/syuan3/gem5/build/X86/mem/heap.hh:17: multiple definition of `****' build/X86/cpu/o3/lib.o.partial:/home/syuan3/gem5/build/X86/mem/heap.hh:17: first defined here collect2: error: ld returned 1 exit status scons: *** [build/X86/gem5.opt] Error 1 scons: building terminated because of errors Best regards.
