When I ran the gem5 in a server, the error appeared.
[libprotobuf FATAL google/protobuf/stubs/common.cc:68] This program requires version 3.5.0 of the Protocol Buffer runtime library, but the installed version is 3.4.0. Please update your library.

According to the error information, I need version 3.5.0 of libprotobuf. But when I ran the command protoc --version, The output is "libprotoc 3.5.0" which shows that I already have version 3.5.0.
The same code can be run in another server. I run the command protoc --version in that server. It shows
"libprotoc 2.6.1".
