Hi protobuf experts,
I am trying to use protobuf static libraries with cmake configurations.
Now it can build and run successfully for windows and mac.
But for linux, I always get the unresolved link errors as below, can anyone
help on this?
link errors:

Hi all,
I was hoping for some advice for designing my publish subscribe system on
top of protobuf and rpc.
The idea is that a developer may have defined set of messages, a normal
service and some rpc methods which they then augment with some publishers
and subscribers.
For example, given this

Another option is to use C++11 scoped enum syntax:
enum class Foo {
FIRST = 0;
SECOND=1;
}
and then generate scoped enums, which would look exactly like the snippet

- deserializing the data in java with protobuf takes 58ms
The amount of data being sent is: 3,959,368 bytes in 158,045 messages
(composed in batches of 1000).

If I comment out the actual serialization and sending of the message
(so I am just composing messages, and clearing them each batch) then
the 100ms drops to about 50ms.

In my stream implementation I'm buffering every 16kb, and calling send
on the socket once i have 16kb.
Thanks!

Hey Bart, I'm not sure I'm seeing the full details of your situation,
But on windows I compiled a library libprotobuf.lib, and linked to it
statically, meaning it gets built into the exe (or dll) you're building.
(I built 2 actually, a release one and a debug one).

Yes, this is a known bug resulting from the fact that I developed the
