Phashion crashed for fingerprint on Ubuntu 22

[matthieubrau]

Hello,

I'm trying to use Phashion on Heroku stack 22 (Ubuntu 22)
ruby => '3.1.2'
rails => '7.0.4'

I'm adding builpacks below :
https://github.com/jayzes/heroku-buildpack-jpegoptim
https://github.com/jayzes/heroku-buildpack-optipng
https://github.com/maximusdominus/heroku-buildpack-imagemagick-webp.git

It was working on Heroku stack 18 (Ubuntu 18)
ruby => '2.6.4'
rails => '5.2.3'

And it's working on my localhost (Ubuntu 18)

Looks depending Ubuntu version...

Here is the error :

When I'm trying to resolve fingerprint I have an error and the console crashed :
ruby: symbol lookup error: /app/vendor/bundle/ruby/3.1.0/gems/phashion-1.2.0/lib/phashion_ext.so: undefined symbol: _ZGVbN2v_cos

Phashion::Image.new(tmp_filename) => works
Phashion::Image.new(tmp_filename).mh_fingerprint => works
Phashion::Image.new(tmp_filename).fingerprint => crashed

Thanks for your help

I'm also seeing this error on ubuntu 22.04 with ruby 2.7.7

When running the tests on the gem (rake test), I get the following error:

./home/deploy/.rvm/rubies/ruby-2.7.7/bin/ruby: symbol lookup error: /home/deploy/phashion/lib/phashion_ext.so: undefined symbol: _ZGVbN2v_cos

the following commit, in a fork of the project, seems to fix the issue:

@rounders thanks for pointing out the specific issue.

I merged in #94, which contained the -lm that was linked to.

@matthieubrau are you still having this issue?

@westonplatter I had the same issue under amazonlinux-2023 with Ruby 3.2 but after pulling your changes it is not happening anymore. Can you please publish a new version so I can properly reference the updated gem?

[kimegede]

Any updates on creating a new tag? 🥺 🙏

[ryoga-chan]

@westonplatter please update the gem in the official rubygems repository, this simple issue keeps repeating itself over the years 🙏

PS: I also addressed some chores present in other issues, I can create a PR if you wish 👍

• fixes #20 patch pHash to support alpha channel PNGs #23 - store the original pHash source code and extract the patch to a separate file
• chore: Update CImg to 179 because it fixes leaking file descriptors #65
• Licensing problem #68 - set same LICENSE as pHash library
• chore: Update config.{guess,sub} to support newer architectures (now builds on ARM64!) #76
