build failed, fatal error: ns3/opengym-module.h

[wangs0622]

when I build ns3-gym by the ./waf build, I get an error like:
In file included from ../scratch/linear-mesh-2/mygym.cc:21:0: ../scratch/linear-mesh-2/mygym.h:26:32: fatal error: ns3/opengym-module.h: No such file or directory compilation terminated. Waf: Leaving directory '/home/wangs0622/ns_3_workspace/ns3-gym/build' Build failed -> task in 'linear-mesh-2' failed with exit status 1 (run with -v to display more information)

And I found the opengym-module.h is used by many files in scratch directory. But the opengym-module.h is not existed in the build/ns/ directory. So I think the error reason is that I don't have the opengym-module.h file.

How to deal with it? and where can I get this header file? Thank you~

[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.

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

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.

[HninPannPhyu]

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

[LiYufengzz]

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.

As for

error message "Protocol Buffer messages are missing. Please run ./waf configure to generate the file").
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
