Protobuf support only compiles with version 3.4.0

[chrischen]

Thought this should be noted as it states minimum version is 3.0.0, but it doesn't compile unless 3.4.0 is used.

It should work with Protobuf 3.0.0 as well.
Compilation problems with Protobuf are very common because multiple versions often exist on the same system.

Hi @YuvalNirkin
I am not able to compile this source code because of protobuf. I get a lot of errors like below
undefined reference to google::protobuf::Arena::AllocateAligned(std::type_info const*, unsigned long)'`

I have tried protobuf versions 2.6.1, 2.7.0, 3.0.x, 3.4.x but none of them seem to work
Any clue on what to fix ?

Thanks
Akash

All Protobuf versions 3.0.x and above should work.
What you're getting is a linkage problem, make sure that you're linking with the right Protobuf libraries.
