[protobuf] Re: Linking error with protobuf 2.6.1 while building ignition-messages0 on ubuntu 16.04
Solved this by linking with protobuf 3.7, just linked in cmakelists.txt , Generator.cc with "protobuf::libprotoc protobuf::libprotobuf".

[protobuf] Re: Linking error
Thanks for answer. No I do not have any inline settings. I suspect the reason is that I use windows 7 since the linking problem disappears when I use windows 10!

[protobuf] Re: Linking error
Those functions are marked "inline", so the compiler should not be emitting references to them. Do you have any unusual inlining settings on your compiler/project?
