is it possible to run Magick.NET-Q16-AnyCPU v14.7.0 on Ubuntu 18.04 ?

Hello!

I have been running Magick.NET-Q16-AnyCPU v14.0.0 on Ubuntu 18.04 successfully for over a year now.
I have recently updated my project to v14.7.0, and now when attempting to run my HEIC image conversion to PNG, I encounter the following exception:

System.TypeInitializationException: The type initializer for 'NativeMagickSettings' threw an exception. ---> System.DllNotFoundException: Unable to load shared library 'Magick.Native-Q16-x64.dll' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libMagick.Native-Q16-x64.dll: cannot open shared object file: No such file or directory

Following the instructions, I enablee LD_DEBUG=libs in my docker-compose.yml file, and when I recreate that Exception again, I now see the following:

The first two lines say it all. version `GLIBC_2.29' not found

When I run ldd --version, I see that I am running:

ldd (Ubuntu GLIBC 2.27-3ubuntu1.6) 2.27

I am looking into the effort required to upgrade GLIBC to 2.29 on my Ubuntu docker container, but from what I've read, that is not recommended, as the highest level GLIBC version for Ubuntu 18.04 is 2.27.

At the moment I am constrained to running Ubuntu 18.04, so upgrading the base operating system is not possible at this moment.

Has anyone else successfully ran Magick.NET-Q16-AnyCPU v14.7.0 on Ubuntu 18.04 ?

Thank you very much!

I don't know when but at some point I had to switch the build from Ubuntu 18.04 to Ubuntu 20.04. There were special patches in place for GLIBC 2.27 compatibility but they all have been removed because I no longer need them. So the short answer is no. You could still try to make a fully custom build that use 18.04. But if you are using Docker I would recommend switched to a newer version of ubuntu as your base image. And I also wonder if you are aware about this: https://ubuntu.com/engage/18-04-lts-end-of-support-webinar.

If you continue to run Ubuntu 18.04 LTS without ESM, you will not receive any security updates after 31 May 2023. Security vulnerabilities that remain unpatched open your systems to hackers and the potential of a major breach.
