Missing libgomp prevents imagick from loading

[netsensei]

Description

The Docker image pulls Imagick 3.5.0 via PECL. However, the PHP extension requires a dependency on a shared library which isn't included in the Dockerfile. As a result, PHP will throw PHP core warnings and CraftCMS will yield PHP errors both via PHP-FPM as well as via the CLI.

Steps to reproduce

1. Set up a fresh environment and use the Dockerfile to build an image. (I use Docker Compose)
2. In my case, I try to restore a SQL dump using the craft command via the docker CLI tool:

$ docker exec -it project_name php craft db/restore /var/www/storage/backups/project--
2021-06-30-084743--v3.6.15.sql

I get these errors:

PHP Warning:  PHP Startup: Unable to load dynamic library 'imagick' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick (Error loading shared library /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick.so (Error loading shared library libgomp.so.1: No such file or directory (needed by /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick.so))) in Unknown on line 0
Restoring database backup ... done
PHP Core Warning 'yii\base\ErrorException' with message 'PHP Startup: Unable to load dynamic library 'imagick' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick (Error loading shared library /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick.so (Error loading shared library libgomp.so.1: No such file or directory (needed by /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick.so)))'

This caught my eye: Error loading shared library libgomp.so.1: No such file or directory (needed by /usr/local/lib/php/extensions/no-debug-non-zts-20190902/imagick.so)

So I added libgomp to the Dockerfile, like below, and rebuild the image. That solved the issue for me.

RUN set -ex && \
    apk --no-cache add \
    ...
    libjpeg-turbo \
    libgomp \
    freetype-dev \
    ...

Fixed in the latest version of the images (1.3.1)!
