Custom build and usage of rucaptcha library

[rautniraj]

Hello @huacnlee

I have made some changes like controlling opacity of the background circle. For this i had to build this gem locally so that it can be integrated in my project. I have successfully compiled and generated .so file which is working as needed in my project. Ruby version used is 3.3.0

The issue is my entire application needs to run in a docker setup which uses base image - ruby:3.3.6-alpine3.20

Now integrating in this setup cause issue. I will describe my issue in short..hope i get some solution

Relative path to this rucaptcha folder containing all the code : lib/rucaptcha

Commands i ran to generate .so file

1. bundle install
2. bundle exec rake compile && bundle exec rspec spec

(Earlier bundle exec rake compile was giving error as in my machine Ubuntu 20.04 there was no rust and cargo installed. Tracing the error message i inferred that both needs to be installed. So i installed both latest stable version only and then compiling happened perfectly)

Above two commands generated .so file. Here is my directory structure

Now in my gemfile i used this gem as : gem 'rucaptcha', path: 'lib/rucaptcha'

Configuration file is kept as it is, using all the default value. Except for the self.cache_store which is set to redis container.

Above works very well in my development setup. But when building inside my docker it fails. Let me attach the screenshot :

useradmin | Postgres host: db
useradmin | Postgres port: 5432
useradmin | Redis host: redis
useradmin | Redis port: 6379
useradmin | bin/rails aborted!
useradmin | LoadError: Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /usr/src/app/lib/rucaptcha/lib/rucaptcha/rucaptcha.so) - /usr/src/app/lib/rucaptcha/lib/rucaptcha/rucaptcha.so (LoadError)

useradmin | /usr/src/app/lib/rucaptcha/lib/rucaptcha.rb:10:in rescue in <main>' useradmin | /usr/src/app/lib/rucaptcha/lib/rucaptcha.rb:5:in

'

This part of the rucaptcha.rb located inside customgem/rucaptcha/lib/rucaptcha.rb is throwing error
