Hello!
I’m trying to integrate yours brand new Ruby SDK 3 with our Rails 6 application. And unfortunatly stucked at connecting to cluster from dev environment with Segmentation fault error. Could you please guide me where I’m wrong? I’ll start from the beginning of my struggle.
My setup is: Ubuntu 16.04.7 LTS, rvm 1.29.12 (latest), Rails 6.1.3, Ruby 2.7.2p137, gem couchbase ‘3.1.1’ from yours sources, cmake version 3.20.2. Also I have installed libcouchbase-dev, libcouchbase2-bin, libssl-dev, build-essential.
I run Couchbase Server inside Docker container with docker-compose in such a way:
couchbase_server:
image: couchbase:community-6.6.0
restart: always
volumes:
- ./couchbase:/opt/couchbase/var
ports:
- “8091-8094:8091-8094”
- “11210:11210”
And through web panel it works great, everything works fine. I added travel-sample bucket and executed several N1QL queries, all good.
First I attempted to install couchbase gem from rubygems sources. I guess I tried everything that was generally available in the public docs, forums, etc. Building everytime fails at ~31%. I don’t know does it matter to install gem from rubygems?
And finally I installed it from yours sources with Bundler and Gemfile like this:
gem ‘couchbase’, ‘3.1.1’, platforms: %i[ruby], source: ‘https://packages.couchbase.com/clients/ruby/2.7.0/’
With Irb it works fine! But when I try it in Rails console or from Controller actions all my dev environment fails. Here is log:
$ rails c
