can somebody help me ...

[shelhamer]

Please ask on caffe-users. Issues are for development discussion. Thanks!

The core developers don't have RHEL machines, so I'm sorry we can't help with this question. Try installing protobuf from source?

@lixin7895123 I got the same error and google directed me here. Did you have any luck fixing this?

[lixin7895123]

@Russell91
NO, I give up on fixing it.
using another computer now.

@lixin7895123 The problem on my machine ended up being that the version of libprotobuf available through yum was out of date. I installed it by hand from https://github.com/google/protobuf/ using the simple instructions in the readme and got all the tests to pass.

I was just banging my head against this same problem. Maybe a minimum version of protobuf should be specified in the installation instructions? It will compile fine against v2.3.0, but apparently won't run with it.

When using protobuf version 2.3.1, I ran into the same problem. Then I compiled v2.6.1 and the problem solved.

The problem should be the old version of protobuf on RHEL. I have same issue and solved by compiling with a new version of protobuf.
