Topic: php_imagick problems (Windows, php 7.4.21)

[laurin1]

I have had zero issues with this in years. Prior to that, we were always having trouble getting this to work. Suddenly, this is failing on 2 machines (maybe more, but we know of 2 for sure, both dev machines). Nothing has changed - no updates, no config, nothing, just suddenly, on 2 dev machines it fails. This does not fail on at least 1 other dev machine and our test machine (luckily also not failing in production).

C:\windows\system32>C:\PHP\php.exe -cC:/php/devrc/php.ini -m

Warning: PHP Startup: Unable to load dynamic library 'imagick' (tried: ext\imagick (The specified module could not be found.), ext\php_imagick.dll (The specified module could not be found.)) in Unknown on line 0

I have tried everything I can think, and as far as I can tell, these are identical. Using the php_imagick.dll and artificat that Jan E creates.

Help!

I even took a brand new VM. Copied the files from the failing machine (c:\PHP and c:\imagemagick) to that machine. Installed vcredist140. Failed with the same issue. Added c:\imagemagick to the %PATH% variable. Works!

I have verified that c:\imagemagick is in the path and even tried copying the files to c:\PHP, still fails. Something has changed that is affecting 2, and only 2 (so far), machines. All machines are Windows 10 21H1 or Server 2019, the 2 that are failing are Windows 10 21H1.

Could it be that you have or once had used the ImageMagick installer on the failing machines? What happens if you do run the installer? Assuming you are still using the x86 version run that one and use “C:\Program Files (x86)\ImageMagick” as install directory, without adding that directory to the %PATH%.

[Jan-E]

BTW. The ImageMagick artifacts are VS16 now. Make sure you install the latest vsredist, linked in the downloads section of this forum. For x86 that is https://aka.ms/vs/16/release/VC_redist.x86.exe

Hi,
You can check arch & compiler version of both imagemagick and php (dll,exe) with this command:

@laurin1 is using PHP 7.4.21, so both php.exe and php_imagick.dll are VC15. But the dependent core*.dll’s and im*.dll’s are VS16 now. That is no problem. See https://phpdev.toolsforresearch.com/php-7.4.21-nts-Win32-vc15-x86.htm for a loaded imagick extension with the dependencies.

[laurin1]

I'll try that, but I don't know how that could be the problem. We've made no changes to these in a while, 2 machines with these same exact files (I know they are the same as we put both c:\PHP and c:\imagemagick in in a Git repo, 2 still work (well, many more than that, but I can confirm 2), and 2 now fail. I've copied these files to a brand new VM, as long as c:\imagemagick is in the PATH, these same files work.

[laurin1]

Both php.exe and php_imagick.dll are:

8664
14.16

[Jan-E]

On a almost untouched Windows 10 21H1 in a Virtualbox, I tried running PHP 7.4.22RC1 with the dependent DLL's in the php-directory:

- I installed https://aka.ms/vs/16/release/VC_redist.x86.exe
- I unzipped https://phpdev.toolsforresearch.com/php-7.4.22RC1-nts-Win32-vc15-x86-keith.zip
- I ran php-cgi -i>php-7.4.22RC1-nts-Win32-vc15-x86-keith.htm

The result: https://phpdev.toolsforresearch.com/php-7.4.22RC1-nts-Win32-vc15-x86-keith.htm

You can see that the imagick extension is loaded, but it reports no supported formats.
I had to run https://phpdev.toolsforresearch.com/ImageMagick-7.1.0-2-Q16-x86-dll.exe to solve this.
Even without adding the application directory to the system path the extension found 263 supported formats:
https://phpdev.toolsforresearch.com/php-7.4.22RC1-nts-Win32-vc15-x86-keith-plus-installer.htm

[Jan-E]

Then I did another experiment:

- I had already installed https://aka.ms/vs/16/release/VC_redist.x86.exe
- I downloaded the official PHP 7.4.21 NTS x86 zip from https://windows.php.net/downloads/releases/php-7.4.21-nts-Win32-vc15-x86.zip
- I unzipped it to C:\PHP
- I added php_imagick.dll to the C:\PHP\ext directory and added it to php.ini
- I ran https://phpdev.toolsforresearch.com/ImageMagick-7.1.0-2-Q16-x86-dll.exe and installed it to c:\imagemagick, this time with adding the application directory to the system path

The result of a 'php-cgi -i':
https://phpdev.toolsforresearch.com/php-with-imagemagick-installed-in-the-imagemagick-directory.htm
See the Environment section in the phpinfo dump to view the system path.
php.ini:

[laurin1]

Thanks for doing that. Not sure what that shows us. Like I said, the files that I am using work fine on most machines, but suddenly do not work on 2 machines. I really think the issue is environmental - some supporting files are different.

Already tried that as well:

Nope.

currently on php 7.4.21 and updated imagick to 7.1.0-2 Q16 x64

maybe you have a bad batch?

[laurin1]

I'm using the exact same files on every machine - I know because both c:\imagemagick and c:\PHP are in Git repos. These have worked for years, but now those same files don't work on 2 machines. I even copied the files from a failing machine to a VM, these work fine on the VM.

[Jan-E]

Are there other core_*.dll’s and/or im_*.dll’s on the failing systems, in the path or outside of the path?
