Best regards.

This is clashing with gem5 behaviour of warning on undefined symbols (Wundef). Feel free to remove the Wundef locally (as a hack) or choose a protobuf version which is not breaking with Wundef. I’ve found that protobuf 3.6.1 is gem5 compatible Giacomo From: Shougang Yuan via gem5-users <[email protected]<mailto:[email protected]>> Sent: 22 May 2020 20:57 To: gem5 users mailing list <[email protected]<mailto:[email protected]>> Cc: Shougang Yuan <[email protected]<mailto:[email protected]>> Subject: [gem5-users] Protobuf error on different ubuntu version Hi, All, I developed some code based on gem5 and ran it on ubuntu16 before. Recently I have installed a newer version of ubuntu18 and tried to re-run my code. I pulled the cold to my private github repo on ubuntu16 and clone it again to the ubuntu18, but I suffered the error as shown in the following: [libprotobuf WARNING google/protobuf/compiler/parser.cc:547] No syntax specified for the proto file: packet.proto. Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. (Defaulted to proto2 syntax.) [ CXX] X86/mem/abstract_mem.cc -> .o [ CXX] X86/mem/comm_monitor.cc -> .o In file included from build/X86/mem/comm_monitor.cc:46:0: build/X86/proto/packet.pb.h:314:6: error: "PROTOBUF_INLINE_NOT_IN_HEADERS" is not defined [-Werror=undef] #if !PROTOBUF_INLINE_NOT_IN_HEADERS I tried some methods from gem5 user lists and did not make it work again. I am wondering if someone else faced the same issues, and if there is a known fix for this. Thanks for your help. Best regards.
