Missing binaries error with image_optim_pack in production

Question

I'm trying to deploy a Rails app with paperclip-optimizer and it's giving me an error about missing binaries. I have bundled image_optim_pack to provide the binaries but still get this:

Have you disabled image_optim in your asset pipeline? config.assets.image_optim = false in config/application.rb – Mohur

@PaulColeman I haven't. I thought that I wanted that to be on so it's doing all assets. – Hoxie

@PaulColeman I tried turning it off but it didn't effect uploading a paperclip attachment - which is where I'm seeing the error. – Hoxie

Have you SSHed into the machine to verify that the binaries have in fact been installed? – Hengelo

It turned out to be an issue with my 64-bit kernel and 32-bit environment. It wasn't able to determine the correct version to link to. – Hoxie

@MarkRobinson If you think it's a situation others might run into, would you mind explaining your solution in an answer to your own question? – Hengelo

Thanks @Hengelo my solution is to rebuild my production server as fully 64-bit. I tried a few hacks but couldn't get them to work for me. I should reference my github issue on this for folks following: github.com/toy/image_optim_pack/issues/12 – Hoxie

Answer 1

tl;dr, the binaries in image_optim_pack were probably built against a newer system than the one you are trying to run it on. Try finding the latest version of image_optim_pack that works on your system. For me, the following versions worked:

gem "image_optim", "~> 0.25"
gem "image_optim_pack", "= 0.2.3"

To get information on what piece is failing, run:

$ bundle exec image_optim --info

I see something like this:

$ bundle exec image_optim --info

Workers by format:

It doesn't say why the workers failed. But you can run the worker binaries to find out:

I think the important part is:

version `GLIBC_2.14' not found

I checked the version of glibc installed on my system, and it is only 2.12. If you are able to upgrade glibc via your system's package manager, try that first. If you can't upgrade glibc, then just use an older version of the gems as described above.

Answer 2

I had the same issue with image_optim_pack version 0.5.020170815.

Upgrading to the most recent version (0.5.020170831 as of now) fixed the issue for me.

Capricecapricious

Thanks but I'm still seeing the error with 0.5.020170831 – Hoxie

@MarkRobinson is the image_optim_pack entry AFTER the image_optim entry in the Gemfile? – Capricecapricious
