Cannot Start Server

[akefirad]

I'm trying to build and use mzbench + vmq_mzbench, but cannot get it running. What I did:

1. git clone https://github.com/satori-com/mzbench
2. cd mzbench
3. virtualenv -p python2 venv
4. source venv/bin/activate
5. pip install -r requirements.txt
6. ./bin/mzbench start_serve

and it fails with:

Executing make -C /home/rad/src/github/mzbench/bin/../server generate
make: Entering directory '/home/rad/src/github/mzbench/server'

Makefile:87: recipe for target '.make/compilation-up-to-date' failed
make: *** [.make/compilation-up-to-date] Error 1
make: Leaving directory '/home/rad/src/github/mzbench/server'

The environment is:

Ubuntu 18.04.2 LTS
Erlang/OTP 22
Erts 10.4.4
Rebar 3.11.1
Python 2.7.15+

Then I thought it might be because of the newer version of Erlang/OTP. Then I tried to do the same with Erlang/OTP version 20.3, but it failed with a different error 😞
I also tried to get it running using the RPM package on a CentOS machine:

sudo yum install -y <rpm_file_downloaded_from_github_releases>
sudo pip install mzbench_api_client
mzbench start_server

But it seems start_server is not a valid command, since it fails with the help message.
Can you please help me with this? Thanks.

Hi @akefirad thanks... as a first thing, could you use https://github.com/mzbench/mzbench instead of the old satori fork?

[akefirad]

Sure, I think I tried it and it failed with the exact error. I'll retry again. (would you like to update the README about the repo? I can provide the PR)

[akefirad]

Yup, failed with the same error 😞

[ioolkos]

PR's welcome! The error compiling meck must be due to OTP 22 (complaining about get_stacktrace becasue it's treating warnings as errors)

I'll try compiling a fresh clone on my machine with OTP 21.3. Bear with me... I'm on a slow cell phone network and technically on vacation :)

[akefirad]

Sure thanks for the support. Enjoy your vacation.

[ioolkos]

Confirmed that compilation works for me with OPT 20.3. (on Ubuntu 16.04, using the virtualenv)
This is due to deprecation warnings in OTP 21 and 22 treated as errors in various dependencies.

While this is fine in principle we should look into this with MZBench. Current OTP compatibility would be great there.

[akefirad]

Thanks for the reply. Do you have any idea when it might be fixed? And also as I said I tried to compile it using OTP 20.3 on my machine (Ubuntu 18.04.3) but it failed. Can you please try on U 18.04 too? (Do you want me to post the error?)
