PHP Startup: Unable to load dynamic library 'imagick' on imagick 3.5.0

[mrmkrs]

Hi,

our tests are failing because of the new imagick version. If i change pecl install imagick to pecl install imagick-3.4.4 everything works as expected.

/app $ php -v

Please can you look in the file config.log that should have been generated when you compiled the 3.5.0 version, and search for checking omp_pause_resource_all usability, and post the contents from that here, down to the next line that has a "checking" on it.

And also, search for a file named libgomp.so.1 with something like find / -name libgomp.so.1 and say where it exists on your file system.

Also, please can you say what platform you're using. And if it's a Mac, try editing the file that was altered by this commit - c9319d1

Fast response :)

I cannot find this config.log, think it should be in a temp folder which is removed. I'm building this in a docker image on Linux. Found out that there is some compatiblity issue with gd:

FROM php:7.4-fpm-alpine3.12 AS dev

RUN docker-php-source extract \
    && apk --no-cache add libpng-dev libjpeg-turbo-dev imagemagick-dev imagemagick build-base autoconf make \
    && docker-php-ext-configure gd --with-jpeg \
#    && docker-php-ext-install gd \ # uncomment this to make it fail
    && pecl install imagick \
    && docker-php-ext-enable imagick \
    && docker-php-source delete \
    && apk --no-cache del build-base autoconf

This will install everything correct unless you uncomment that line.

When it does work libgomp.so.1 is located at /usr/lib/libgomp.so.1. If it doesn't work, than I cannot find libgomp.so.1.

Hope this info makes sence :)

So, running the problematic command docker-php-ext-install gd separately, you can see that it's deleting the libgomp and some other libraries:

(12/20) Purging libgomp (9.3.0-r2)
...
(17/20) Purging libmagic (5.38-r0)

Please can you open an issue at https://github.com/docker-library/php/issues ?

Installing software shouldn't delete libraries installed on the system...

[Danack]

Okay, I'm going to close this.

Although I'm not going to stop people from using Imagick on Alpine, I don't use it myself, so don't really want to get involved with packaging issues, unless they are actually my fault.

Also #328

Thank you for looking into it!

I'm still encountering this issue and this https://github.com/docker-library/php/issues/1173#issuecomment-869870348 helped me get imagick working again in my docker image, it'd be great if GD would not remove what it shouldn't, at least not without checking if something else relies on that library.

basically I just reinstall libgomp after I setup all of my modules and boom, everyone is happy again. :)
