DMSf Installation error on "bundle install"

[vergelli]

Hello, I'm having an issue when installing the newest version of DMSf, however, the problem itself might not be related to DMSf, so if you consider that this does not belong here I will understand it. Sorry in advance.
But I thought that maybe you would be familiar with this error and know a practical way to tackle it.

On point 4.:
"4. Install dependencies: bundle install"

After running: bundle install

I recieve:

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x64-mingw32, x86-mswin32. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x64-mingw32 x86-mswin32`.

An error occurred while installing ox (2.14.4), and Bundler cannot continue.
Make sure that `gem install ox -v '2.14.4' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  ox

Seems there is a problem with the ox Gem.
To be honest, I'm not an Expert with Ruby or Rails, and before starting to touch, and try the recommendations that are being shown there, (with the risk I break everything >.<" ), first I'd like to know if you know a practical way to solve this issue.

Sorry if this is Offtopic.

It's very probably a missing library in your system. What is in /usr/local/bundle/extensions/x86_64-linux/2.6.0/ox-2.14.4/mkmf.log?

Run gem install ox -v '2.14.4' --source 'https://rubygems.org/' and go through all related logs as recommended in the output. There must be an error that has to by fixed.

Hello, I tried the command and I got, the result that follows:

One question, what does the OX Gem do? Is it indispensable? Could I ignore it? Don't know if there is another Gem that has issues with the installation yet. This Redmine is running on a Docker Container inside a Centos 8.

[picman]

Package build-essential installed?

ox package is required by the WebDAV module and is referenced in Gemfile.

[vergelli]

Actually, yes, after running apt-get install -y build-essential it worked. It may be good to point out I have this Redmine running on a docker container.
Thank you
