I have a similar error, but after updating protoc, the error still exists.

@Forsworns , have you solved the issue (open gym). I have face the exact same error.

[wangs0622]

I have solved this problem. The main reason is that my protoc version is 2.6.1， it must be greater than 3.0。 After I update this protoc manually, I can build successfully.

The same as your errors, though I have upgrade to the latest protobuf manually.
It seems the opengym module is not built as it is supposed to.

here is my ./waf configure output,

And the /src/opengym/model/ns3gym/ns3gym/messages_pb2.py is not generated when I run ./waf configure before. After configuration, I run pip install ./src/opengym/model/ns3gym and get this error message "Protocol Buffer messages are missing. Please run ./waf configure to generate the file").

I removed the scratch dir and the other modules are built successfully, except opengym. Do you have any idea why it is not built? I have run ./waf clean before the cofiguration.

I have solved this problem. The main reason is that my protoc version is 2.6.1， it must be greater than 3.0。 After I update this protoc manually, I can build successfully.

I have the same question,when I update the'protoc',it can't build correctly,still.

[dubin142857]

My protoc version is greater than 3(3.6.0),but i still face the problem....sad

[JuBeeInc]

I also have the same issue with Opengym-module.h it does not exist after building.

Hope the creator can help us resolve this.

[Zhangjinjin123]

I have a similar error, but after updating protoc, the error still exists. [1795/1863] Compiling scratch/opengym/sim.cc ../scratch/opengym/sim.cc:23:32: fatal error: ns3/opengym-module.h: No such file or directory compilation terminated.

Have you solved this problem? I also have this problem. How can I solve it?

[Forsworns]

Sorry for the late response, I have not worked on that project for a long time...

To be honest, I gave up and didn't use ns3-gym finally. Instead, I directly communicate with python code by Python/C API

if you can read Chinese and interested how to do this, here is my notes written during implement that.

of ns3-gym

I cannot remember this. I can only find some clues in my notes mentioned above: check your zmq version, protoc location, try to leave anaconda environment ...

Thank you very much for your reply. I didn't install zmq. This problem has been solved, but there are other problems during the test
