which unix env is supported, can u state your env?

[larrycai]

I tried to install it in ubuntu bionic + python 3.7 env, but it doesn't work, it ends it could be an issue in upstream which I register there dds-bridge/dds#94

I wonder which platform do you use, will be nice if u have workable Unix platform. If u only verified in windows, then I will focus on windows

BTW: found this from your blog http://datadaydreams.com/posts/a-simulation-tutorial-for-better-decisionmaking-at-bridge/ (excellent work!!)

Things work on Linux for me (Arch Linux or Fedora). In fact the CI testing (via azure-pipelines.yml) is only done on Linux...
The memory issue you mention on the dds tracker should have been fixed by d7e38ae.

[larrycai]

I tried for that pull (change the link in submodule), it doesn't work on ubuntu, i tried it for fedora/centos as well.

Can you state the env for fedora or arch linux? so I can try for docker like archlinux/base

[larrycai]

from the azure-pipelines.yml looks it supports ubuntu 16.04

I tried below fedora according to the guideline with no success, will be appreciated if u can make it work

$ docker run -it  fedora:31
# dnf install -y git gcc-c++ make boost-devel python3-pip
# python3 -mpip install --user --upgrade git+https://github.com/anntzer/redeal
# cd /root/.local/lib/python3.7/site-packages/redeal
# export LD_LIBRARY_PATH=$PWD
# python3 -c 'from ctypes import *; dll = CDLL("libdds.so");'
sh: free: command not found

Same for ubuntu 18.04 (bionic), not sure which is missed

$ docker run -it ubuntu:bionic
apt-get update
apt-get install -y g++ make git libboost-all-dev libomp-dev python3 python3-pip
python3 -mpip install --user --upgrade git+https://github.com/anntzer/redeal
cd /root/.local/lib/python3.6/site-packages/redeal
export LD_LIBRARY_PATH=$PWD
python3 -c 'from ctypes import *; dll = CDLL("libdds.so");'

You need to install procps-ng (on arch/fedora -- whatever provides /usr/bin/free on other distros). I guess that can be considered a dependency of dds... feel free to open an issue on their tracker.

[larrycai]

I installed the procps for ubuntu & procps-ng for fedora. but both don't work still.

[anntzer]

What does running /usr/bin/free -k return?

[larrycai]

# free -k
              total        used        free      shared  buff/cache   available
Mem:        1989472      601400      169936      107636     1218136      681832
Swap:             0           0           0

has issue with swap ?

[anntzer]

I pushed a (local) patch to dds which should fix that.

[larrycai]

excellent, now it works in simple way, see Dockerfile

FROM python:3.7.5-slim-buster
RUN apt-get update && apt-get install -y g++ make git libboost-all-dev procps
RUN python -mpip install --upgrade git+https://github.com/anntzer/redeal

then I can simple do

$ docker build -t anntzer/redeal .
$ docker run anntzer/redeal redeal

Do you want me to contribute PR in your document? or leaving this in issue is enough

[larrycai]

create repo for the docker image https://github.com/larrycai/docker-redeal, I will use this to reproduce your article.

[anntzer]

In theory nearly any unix env should work now (I patched out the dependency on procps-ng), so I don't think there's much to add and this can be closed now?

[larrycai]

thx
