I encounter the problem when running seprantine scenario. Specifically, snakemake -jall yields an error, here is a log

I use windows 10, 64 bit
Python 3.8
veins-gym 0.3.0
gym 0.21.0
omnetpp 5.6.2
sumo-1.8.0
veins 5.2
protoc-3.19.1

Note that I also receive an error when running opp_run. From the error message it does not seem that those issues are related, but if they are - I will provide the log.

How could I solve the problem? Thank you!

Hi,

can you run one of the failing commands directly in the terminal and check what the error is? E.g.

env -C lib/veins-vlc ./configure --with-veins=../veins
# or 
env protoc --proto_path src/protobuf --cpp_out src/protobuf src/protobuf/veinsgym.proto

I suspect that -- as you are working on Windows, your shell environment may not be set up as expected. We've designed and tested the gym only on Linux so far. So maybe the env command or the protoc calls do not work as expected.

Best,
Dominik

[RostyslavUA]

Thank you for the answer!
You are right,
env -C lib/veins-vlc ./configure --with-veins=../veins
yields

'env' is not recognized as an internal or external command,
operable program or batch file.

How should I set up my environment to make it work?

[dbuse]

Your OMNeT++ installation should have brought with it a MinGW environment which contains the necessary environment to execute unix shell scripts. Try to open a console from that or add its binaries to your PATH.

An alternative could be using Windows Subsystem for Linux (WSL) or git bash, which also both bring the necessary tools to your command line environment.

[RostyslavUA]

Thank you for the answer. For already many days I am trying to make it work. I have switched to Linux as you suggested and I use Ubuntu-20.04 on wsl. Now I stuck at the following point: when running snakemake -jall, this is the error I get

Shutting down, this might take some time.
Exiting because a job execution failed. Look above for error message

It seems to me that maybe it is the problem with the linker or with protobuf version. My protobuf version is libprotoc 3.19.1
Could you please give me some hints on how could I circumvent the issue?
Thank you!

[RostyslavUA]

I would like to send post this message as a reminder, because I am afraid that my message got lost

[RostyslavUA]

Eventually, I have solved it by removing protobuf that I have installed manually (which had a version libprotoc 3.19.2) and running sudo apt-get install protobuf-compiler, which for me had a version libprotoc 3.6.1. I am not sure whether the problem was in the version conflict or in some mistake during installation.

[dbuse]

Hy @RostyslavUA, sorry for the late response.

I also assume the issue is due to a mismatch of the generated protobuf-C++-files and the version of libprotoc installed when linking. For future readers, I also suggest to

• check/update the installation of protobuf-compiler and libprotoc on your system (package names may differ based on the Linux distribution)
• remove the generated src/protobuf/veinsgym.pb.h and src/protobuf/veinsgym.pb.cc files
• re-generate the protobuf-files by running snakemake src/protobuf/veinsgym.pb.cc src/protobuf/veinsgym.pb.h
  Hopefully, that helps.

[zaheenSyed]

Thank you @dbuse.

[anjackq]

Hi,

I followed these instructions but I still got the problem. It seemed like the protobuf library is not linked correctly, and finally I figured out, that it is due to the Snakefile:

link_flags = ' '.join(['-L../lib/veins/src/', '-lveins\\$\(D\)', '-L../lib/veins-vlc/src/', '-lveins-vlc\\$\(D\)', '-lzmq', '-lprotobuf']),

The last one -lprotobuf seems not working for the latest Protobuf, so I added another one -lpthread and it works!

And you will get a new Makefile, or you can generate one with the following command:

opp_makemake -f --deep -o experiment -O out -I -I../lib/veins/src -I../libveins-vlc/src -I../lib/zmq/src -L../lib/veins/src/ -lveins -L../lib/veins-vlc/src/ -lveins-vlc -lzmq -lprotobuf -lpthread -e cpp

Hope this will help for others.

Hi, I was hoping you could ask some questions about veins_gym.

Maybe I am not familiar with veins_gym and your example, so some questions may not be quite correct.

I can run the case you provided according to your method. By running python files, however, there is only one result to the whole process. Can it see the detailed process through omnet++ emulation? Can it compile the entire file through omnet++ instead of snakemake?
