windows Apache + PHP 8.1 Unable to find library 'libvips-42.dll'

[flexphperia]

Hi,
I'm having trouble running libvips under Windows.
Of course I have FFI enabled, I have the correct path pointed to libvips, and it still doesn't work.
@jcupitt could you help me on this topic?

Error:
Fatal error: Uncaught Jcupitt\Vips\Exception: Unable to find library 'libvips-42.dll' in any of ['D:\wamp64\www\Tests\libvips-phpbinding/lib64/', 'D:\wamp64\www\Tests\libvips-phpbinding/lib/']. Make sure that you've installed libvips and that 'libvips-42.dll' is on your system's library search path.

My sample php code:

<?php
putenv('VIPSHOME='.dirname(__FILE__));

require __DIR__ . '/vendor/autoload.php';
use Jcupitt\Vips;

$image = Vips\Image::thumbnail('somefile.jpg', 128);
$image->writeToFile('tiny.jpg');

Hi @flexphperia,

Could it be a 32/64 bit mismatch? You'll need to use 32-bit everywhere (php and libvips) or 64-bit everywhere.

Did you see this issue? #183 (comment) There are detailed install notes for php-vips on windows. You could try those (they should work), then check that install against your main one for differences.

I'm using 64 bit everywhere, confirmed. Also checked issue that you mention - no luck.

I have PHP 8.1: compiler Visual C++ 2019, x64 installed as Apache handler but I think it does not matter.

Oh, what exactly is in the lib directory you have on your path? Could you copy-paste the directory contents?

It could also be a clash with another package you have installed. What else is on your path?

[jcupitt]

Could you try following the steps I list in that issue exactly? That should work, so then you just need to find the differences between that working install and the one that's failing.
