add php-imagick dependencies

Problem

I tracked down the error I get from the php-imagick extension

$ php -i
PHP Warning:  PHP Startup: Unable to load dynamic library 'C:\Benutzer\remy\scoop\apps\php7.1-imagick\current\php_imagick.dll' - Das angegebene Modul wurde nicht gefunden.
 in Unknown on line 0
// ...

It is because imagick depends on the correct imagemagick installation.
Hint, the imagemagick package from scoop core does not work ;-)

Solution

The correct version has to be grabbed from http://windows.php.net/downloads/pecl/deps/
Unpacked somewhere and the bin directory has to be added to the PATH and a new environment variable MAGICK_HOME.
Then php-imagick loads correctly.

Problem

Adding the imagemagick dependency to the $PATH overwrites the core imagemagick installation if present and could lead to problems if it is installed …

@r15ch13 do you have an idea how to solve this?

Does it work with ImageMagick version 6.9.8-10?
The scoop version is already on version 7.0.6-0.

Is it just me or does the version change if www. is added to the URL?
https://imagemagick.org/script/download.php (6.9.8-10)
https://www.imagemagick.org/script/download.php (7.0.6-0)

@r15ch13 here is same

Same here for the version difference on the webpage

@r15ch13 php 7.1.6 is compiled against imagemagick 6.9.3-7. Using a newer release does not work,

PHP Warning:  Version warning: Imagick was compiled against Image Magick version 1683 but version 1688 is loaded. Imagick will run but may behave surprisingly in Unknown on line 0

I tried it with ImageMagick-6.9.8-10-Q8-x64-dll.exe, only the -dll releases include the required DLLs

---

The DLL files from the old imagemagick version have to be in the PATH.
MAGICK_HOME doesn't seem to be required.

What about deleting all the .exe files from the php-imagick installation so they do not interfere with other imagemagick installations?

[r15ch13]

What if the ImageMagick DLLs are placed in the same directory as php_imagick.dll? Shouldn't they have a higher priority than the DLLs in PATH.

[rrelmy]

No, they would need to be placed along the php.exe

I added the post_install script described in #2 (comment)
